Re: [RE-wrenches] GENERAC EcoGen 6kw problem
If the unit is still under warranty, have any Generac dealer run through the diagnostics. The testing flow suggests rotor or stator problems, and there is a proscribed testing flow that needs to be performed. If it is determined to be a warranty issue, it will be fixed for you at no cost. If it is not under warranty, I would still have a dealer look at it. There are a large number of possible issues and you are going to spend a lot of time trying to find the problem. A Generac tech will likely find the problem in a few minutes unless it is a serious problem, in which case you were never going to find it. I'm a Generac tech so I can speak from some experience that this is likely not a simple issue.

Re: [RE-wrenches] automatic transfer switch
I think Radians are redundant anyway, if you parallel the output they will keep going when one fails. Also, the 8KW are two x 4KW modules, both can function independently. I know this because we lost one at home and kept going until a replacement arrived.

Re: [RE-wrenches] 1,000V combiners
The reason I need these inverters is we had two CL60 480V inverters with bases, and they fell off the bases in the hurricane and filled with water. They were good inverters but the bases were garbage and could not support the inverters in high wind. Very disappointing as the arrays had only a relatively small amount of damage. I am planning on using the Symo 24 fused inputs directly, recabling to hard wire the strings to the inverters. That's how we do all our European spec systems, it's so much better to have all the strings present at the inverter. Thanks for your advice.

Re: [RE-wrenches] has anyone ever had this happen?
I've done this once because the client had duty free concessions, he had to have the manufacturer's invoices. I quoted him Cost plus 20 for the materials plus a labour fee and a management fee. He took the quote and I never heard from him again, guess he tried to buy the goods at the same cost. One way around this is to explain that you have confidential pricing and giving that to them would break that agreement. On the other hand, I work with a large company that handled the shipping and brokerage, so they had to get my supplier invoices. But, and this may work for you, I first signed a Per-Watt contract with them, so what they seen afterwards didn't make any difference. You can always edit the invoices to make them higher.

Re: [RE-wrenches] Is there a charge controller do this?
PWM chargers should work fine, dial the generators to about 50V. Then the batteries will charge to 50V float, and the solar will manage the stages after that. 4 x 60A PWM charger should do what you want. You can buy a 20A and see how that works so you don't waste much money. On Sun, Jan 28, 2018 at 11:23 PM, Mac Lewis wrote: > Hello wrenches, > > I'm working on 3 off-grid telecom sites.

Re: [RE-wrenches] Li+ Systems Puerto Rico
I live in a Caribbean Island and use off-grid solar with grid as backup when available. We just went through Irma and lost power for three months. I've lived these solutions. I wouldn't use anything other than an Outback Radian for this with a DC charge controller, but finding a good Lithium solution will take a little work. We have 1100 Ah of Lead acid, but only use 20% of that. So 300Ah of useable storage would have been adequate for Lithium and that's what we will use later. Relion looks promising. Right now there is no good integrated Lithium solution.

That's what we are looking at, but it's harder to design for this application, if I didn't have to cost it, I would just go with it.

Re: [RE-wrenches] Lithium Batteries
I'd be very cautious about getting too cosy with any of these battery companies, it seems their only aim is to get bought. Sonnen was acquired by Shell Oil, Pika by Generac. I'm a generac dealer so I am exploring what their intentions are. I doubt Shell will be gung-ho to continue to support solar, so where does that leave my Sonnen customers? Make sure your customers are aware you don't know where this is going and whether any of these guys will stay the course. Companies like trojan and Outback are going to be around, but Fortress? Unlikely. On Fri, May 3, 2019 at 4:34 PM wrote: > Hi Howie, > Have you looked at Fortress Power batteries? We're about to install > some and they look like a very decent battery.

Re: [RE-wrenches] Consolidating meters
It's the consumer's right to have one point of metering and distribute the power to their loads. I would not ask the utility, I would tell them I was rewiring and wanted to have only one metering point. It's stupid to pay for all those meters. Most customers don't realize there is a cost to having multiple meters and the problems it causes when it comes to self consumption. We regularly consolidate customers who have one meter for each guest cottage or main house, once they understand the advantages they rewire and tell the utility to remove the redundant meters.

Re: [RE-wrenches] 120/240 to 3 phase 120/208
Yes, I just did it yesterday, but only if it is a 12 wire alternator. If you open the connection box on top of the alternator, you will be able to reconfigure the alternator. However, that's only possible if the generator was built using a three phase alternator connected in zig-zag to give single phase - which is very common. All the big generators I order are built this way. If you give me more info on the generator I can tell you how to do it. https://www.smokstak.com/forum/attachment.php?attachmentid=3483&d=1125167403 On Tue, Aug 6, 2019 at 10:20 PM Jay wrote: > Hi all > > Is there a way to convert a 120/240v generator to a 120/208 3 phase output? > > Thx > > Jay > ___ > List sponsored by Redwood Alliance > > List Address: RE-wrenches@lists.re-wrenches.org > > Change listserver email address & settings: > http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org > > List-Archive: > http://www.mail-archive.com/re-wrenches@lists.re-wrenches.org/maillist.html > > List rules & etiquette: > www.re-wrenches.org/etiquette.htm > > Check out or update participant bios: > www.members.re-wrenches.org > > -- Chris Mason Solar systems designer Generac Generators Industrial technician Comet Systems Ltd DBA Comet Solar Anguilla Cell 264.235.5670 WhatsApp 264.235.5670 Skype: netconcepts www.cometsolar.com <http://www.cometenergysystems.com/> ___ List sponsored by Redwood Alliance List Address: RE-wrenches@lists.re-wrenches.org Change listserver email address & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://www.mail-archive.com/re-wrenches@lists.re-wrenches.org/maillist.html List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out or update participant bios: www.members.re-wrenches.org

Re: [RE-wrenches] Grid tie w/o battery no sell back
I misunderstood the question the two options I listed are battery systems. What I should have suggested as a solution was the Enphase microinverter system with the Zero Export profile and Production CTs on the service to the panel. That will do Zero Export so that all the power produced is self consumed, there is virtually no exported power to the grid.

Re: [RE-wrenches] seeking PV mounting advice to Shipping Container for Off-grid
I have a bunch of containers, I put solar on a couple. I would weld tabs onto the container so as to avoid penetrations. The worst thing about containers is they leak, so holes in the top are a problem. In fact, I would weld on tabs, put galvanized stringers cross at an angle, put galvanized purloins along the length of the container, put galvanized corrugated sheeting on the purloins and the racking of your choice on top. That way the container roof won't rust and leak, you have your angle, and the container will be cooler.

If you only want to change over, why not use a contactor with three poles, a NO and NC contact? that will switch instantly.

Re: [RE-wrenches] Offgrid Generators?
Ray, I'm a Generac dealer. Why are you having support problems? Generac has a large dealer network, if the unit is under warranty you should have no problem getting it fixed. Did you buy through a dealer and have them install it? Why are the services expensive? What failures are you seeing? There is a hole in the market for products in this application. Virtually no-one makes an affordable ~10KW diesel enclosed 2 wire start 1,800 rpm reliable diesel generator. I once ordered, on spec, a 9KW Perkins engine liquid cooled enclosed diesel from a factory in China I deal with. I sold it to a customer that ran it 18 hours a day on 100% load, to power his restaurant refrigeration outside service hours. It lasted him years, it must have thousands of hours on it. I think the big problem in the US is getting permits for diesel generators.

William, Generac has a structure where box stores like HD and Lowes sell the residential generators and arrange local certified dealers to perform the installation, warranty and service work. The dealers are not real fond of it but Generac can't get to be the largest brand relying on dealers for sales. Generac is pretty good on compensating dealers for warranty work so there are a number of dealers that make their living on installation, servicing and warranty work.

Re: [RE-wrenches] Offgrid Generators?
Generac also has a nice 15KW Diesel Protector unit, that'll keep the lights on very nicely, is relatively inexpensive and I haven't heard any complaints about them failing. We had one Protector Diesel with a failed fuel pump solenoid but I changed it out under warranty and there hasn't been any other issues. Of course they are not $4,000, you are not going to get a liquid cooled generator for under $10,000.

Re: [RE-wrenches] Offgrid Generators?
Ray, Let me try to address some of those issues for you. 1) You can get the activation code before you take it to site, you just need the serial number. Generac has a good warranty policy but they need to know where the generator is and when it is installed to be able to provide that. 2) An electrician can connect the wires but you would not believe the installations we have seen, done by licensed electricians. We have a dealer forum where installers post pictures of installations they find, and the mistakes are criminal and dangerous. I once found a propane 20KW generator running side a shipping container, doors closed. 3) Generac does not do direct support for generators, they require customers call a dealer. The dealer can then call Generac, and often does. I can't even call them if my certification expires. 4) If the generator is under warranty, you may not pay anything, depending on the coverage. Generac is offering up to ten year warranties. But once it is out of warranty, you will have to pay. Dealers don't work for free. The average electrician won't be able to diagnose problems reliably on these generators. The residential air cooled generators are very reliable and rarely have problems if well maintained. Techs should be traveling with common parts, I bring a controller and a few other parts so I can solve the problem in one go. Blown engines are rare, but they do happen. Generally in the first few hours, so under full warranty and replacement is generally done at Generac's expense. If you do have issues, contact me and I will try to help you.

Well said, WIlliam. Just because we are installing solar does not mean all our intent is "green" I provide solar systems and generators, I am a provider of engineering solutions. I do not judge clients based on their green qualifications, just on their ability to pay me. We are in business to provide engineering solutions. By the way, William, have you looked at the SMA Fuel Saver solutions? I am proposing that technology for an industrial customer whose plant runs entirely off generators.

Re: [RE-wrenches] 1000 V meters?
I bought the EX730 for the DC current measuring capabilities but realized it would read 1000V DC systems on the job. It works fine. I don't need precise measurements, just to compare strings to ensure all strings are about equal. If I bought it again, I would get the EX840. It's 1000V CAT IV. I have a number of Extech units, they are fine.

Re: [RE-wrenches] 3-Phase Service, One Phase Fails
I have felt for some time that inverters should have a logic control to turn them off. "Short contact A to ground to disable inverter" type of interface. If we had that, we could implement generator protection very simply. For your application, I see these being used in 3 phase pump control systems. http://www.taylorphaseguard.com/ Let me know if you need any more information.

Re: [RE-wrenches] ECO GEN ALERT
Drake, As a Generac service dealer, I brought your generator problem to the attention of Generac's managers. They had a couple of comments: 1) The activation issue sounds like a misunderstanding. Activation is only a data gathering process, I normally do it online ( https://www.activategen.com/ ). There is no reason why you could not do it on behalf of the customer. The activation reps do not handle service calls. 2) The oil hose issue should have resulted in a shutdown which would have been simple to remedy. There's no record of generators being damaged by this issue. However, if this is what happened, Generac is very good about warranty repair and would be very responsive. I would call the nearest Generac dealer and let them file a warranty claim. It does not matter that the generator was not purchased from the dealer, all dealers are required to handle warranty for any generator as they get paid to repair the units. Generac will advise the dealer how to proceed. You seem to indicate Generac did not want to replace the unit but I also get the feeling no tech has looked at the unit yet. You have to follow the process. Generac will determine the best course of action once they know the details. Feel free to pass on any issues you are having resolving this issue. I can get the service manager involved if you feel you are not getting adequate response but you do need to get a service dealer involved before any repairs or replacements can be discussed.

Re: [RE-wrenches] Generator automatic disconnect
I haven't been a dealer long enough to remember the problems you refer to. We don't have the sales volume to be able to speak with authority on faults statistics but I get the impression that the quality of Generac units has improved a lot over the last couple if years. Most of our problems are related to lightning and bad power from the utility. One of the problems with these air cooled units, from any manufacturer, is the unrealistic expectations of the buyers. People want to spend $3,000 and get a whole house generator with service rated transfer switch, and they think that it will perform like a prime mover. The air cooled units are good for about five or six years of occasional use. I have Kohler units that have failed at about that period. The whole point of the ecogen is the longer run times due to the large oil reservoir. I have a 10 year old Lister Petter diesel with a Stamford 16KW alternator at my warehouse that will run 20,000 hours before it needs a strip down. Generac sells very good industrial diesels, but they cost 6 times as much as an air cooled, so no homeowner will buy them. Most people do not need a heavy duty generator and I see so many businesses here over specify their generators and spend way more than they need to. I visited a store that bought a 200KVA genset so they could run air conditioning, but turned the air conditioning off because the electricity cost was too expensive. Their operational load was only about 20KVA. Anyway, I think you will find the new Generac units are very affordable and reliable, as long as your customers have realistic expectations.

Re: [RE-wrenches] smaller 3-phase commercial inverters
Probably because these small three phase inverters are adapted European designs. In Europe, three phase 415 is normal. The Tripowers have an upper voltage range of 480V so adapting them to the US is pretty easy. To adapt to 208, all the power boards, terminals, and cabling would need to be twice the size, so a total redesign is required. I suspect that the larger Tripowers could never be 208V because of the currents.

Re: [RE-wrenches] Elliot Power Systems MPSG-12
Most gensets are combinations of other manufacturers products, such as a Perkins engine with a Stamford alternator in a housing with a controller. Very few generator manufacturers make their own controllers. You need to find the manufacturer and model of the controller, the genset is irrelevant. Once you get that you should be able to find the documentation.

The project is hybrid, the house has utility power at the moment. I was looking for feedback on the product, I haven't heard comments on the Outback RE battery system. In the end I recommended a single string of TROJAN, IND9-6V. We will revert to grid at 80% DOD. The house is tropical, high in the mountains and doesn't use a lot of power.

Re: [RE-wrenches] Long transmission line inductance and LED light flicker
You should rent or borrow a power quality analyzer to look at the phase angles and harmonic distortion throughout the day. A scope will also help to allow you to look at the waveform of the inverter produced electricity. You need to properly identify the cause of the problem before you invest in any equipment. Resistive loads will not change phase angles. Only capacitive or inductive loads can do that. However, LEDs work fine in commercial installations where 0.8 power factors are common so I doubt that is your problem. It is more likely that badly formed waveforms cause switching issues for the LED's driver electronics. Filtering may help. Line to Line capacitors are probably not going to help, but Line to Earth capacitors could act as a high pass filter to shunt noise to ground.

Re: [RE-wrenches] Solaredge inverters w/ backup generator
That's total nonsense. Most of our installs involve a generator, as generators are very common here due to intermittent electrical supply and hurricanes. We also sell and install generators and I am a tech. A decent heavy generator will produce electricity that will fall within the IEEE 1547 specifications for grid tied interconnections. Additionally, in our area, we alter those settings to widen the windows as the electricity supply on an island is not as stable as a large grid. My rule of thumb is that no lockout is required if there is no risk of backfeeding the generator, that is, if the load will always exceed the solar output by a reasonable factor. We have customers that have constant loads in the 40 to 80KW range, and so 20KW of PV will never cause a problem. Residential is the larger issue, as there is often no load. A generator's output is controlled by the Automatic Voltage Regulator or AVR. It senses the voltage at the terminals of the alternator and changes the excitation to keep the voltage constant. Usually the generator's controller has voltage sensing and will stop the generator if the voltage exceeds limits. If the solar inverter is making power and there is no load, it will increase the voltage until it finds enough load, or trips. If the generator sees the increased voltage and the AVR cannot reduce the excitation enough to control it, the controller MAY shut down the generator. A generator's controller and AVR presumes it is the only source of power on the electrical system. The inverter presumes it is connected to an infinitely large grid system that can absorb all power generated. Our usual solution is to put a contactor in front of the inverter controlled by voltage from the generator, or ideally by a contact on the transfer switch. It may be possible to program the generator to run faster or slower so as to keep the frequency outside the inverter limits, but you run the risk that a future tech will adjust the inverter or generator.

Re: [RE-wrenches] Charging a HUP
A 12KW generator can produce 250A at 48V, and the breaker should be 12KW *125% or 62.5 amps. You may have an unbalanced load, you probably can only put 6KW per leg of the 240V feed.

Re: [RE-wrenches] Outback Chargers
One of the issues to be aware of is power factor, and most people will not be able to determine power factor. If the Outback operates at a poor power factor, your 10KW generator will become a about a 6KW generator. A lot of the current will be wasted and will not produce charging power.

The "Door Open" switch is a very useful feature. I am trying to get Fronius to put a digital shutdown terminal on its CL line of inverters, or all inverters preferably. We need to pressure all the inverter manufacturers to provide a logic in or dry contact method of shutdown. Most ATS will provide a N/O dry to indicate position.

If you are using Sketchup for solar, you should be using the Skelion plugin. It will compute and draw the solar modules on any surface based on your preferred module, tilt angle and azimuth.

Re: [RE-wrenches] Project management tool
The term Project Management can be applied to a wide range of tools and methodology. If your needs are only to track tasks, I would use Wunderlist as it can be installed on every device and lists can be shared. If you want a real PM tool, Microsoft Project is the midrange tool of choice. There are a ton of industry specific platforms that you could use but they are mainly for large enterprises. The problem with PM software is you need time to design and administrate the data. In a lot of projects there is a dedicated person who coordinates all the contractor and subcontractor tasks. It is a full time job. I would be careful about launching into a PM tool that you are not familiar with while already overwhelmed. It will suck up a load of your time and return you very little gain in efficiency. If you have a number of people to coordinate and you think PM software to be the best way, hire a consultant to select and implement the application.

Re: [RE-wrenches] Autocad
D'assault Systeme offers a free CAD program Draftsite, that reads and writes Autocad files. We use it for our drawings. The commands are all the same as Autocad so you can learn for free. They also have tremendous tutorials. http://www.3ds.com/products-services/draftsight/overview/ On Fri, Mar 14, 2014 at 4:28 PM, Jason Szumlanski wrote: > I'm pretty sure the free version of Skelion will do the roof layout.

Re: [RE-wrenches] Unusual problem with SMA TL inverter on metal roof
If the problem is capacitive, it ought to be possible to fit a high resistance conductor between ground and the center point of the arrays to discharge the capacitive charge without affecting power performance.

Re: [RE-wrenches] 1000V System Wiring Details
All the European spec inverters I have used would shut down at 600V so that's not a great idea. On systems with long runs, we use a fused switched combiner and run 1KV #6 for the home runs. But that's for very long runs. You can put a lot of power over a #10 PV Wire at 800V working voltage.
