[RE-wrenches] Problems with Conext SW inverter
I recently discovered a critical problem with a client's SW inverter and I want to know if others have encountered this. It's an SW4024 with Flooded Lead Acid batteries. The system is configured using the Custom Battery setting: Bulk and Absorption are set to 29.2 V. Equalize is set to 32 V. The problem is when Equalize is enabled, the system goes through Bulk and Absorption just fine. However, when it switches to Equalize it doesn't actually equalize. What I observed was the voltage actually decreased to 0.5 V below the Absorption Voltage setting. Eric Smiley, P.Eng.

Re: [RE-wrenches] Problems with Conext SW inverter
It is of grid and, yes, the generator was running when I attempted to equalize. Schneider has no solution and it is just outside the 2 year warranty. I am going to try a couple of things when I go back: - setting the battery type to the default for FLA battery - it is set to Custom battery right now; - installing an older firmware version, to see if it is just a bug in the last update. However, based on the condition of the battery, I suspect the client has never been able to properly equalize; despite thinking they were doing everything properly. A real shame they even released this inverter to the market. This will likely be the third and last CSW that we end up replacing with a Magnum. If anyone else has had issues with the CSW, I'd like to know. We know other installers that believe this was a defective product from the beginning and would like to press Schneider to compensate clients and installers who have wasted far too much time and money trying to make it work as promised.

Re: [RE-wrenches] Rapid Shutdown Compliance
We are running into the same problem with battery back-up, grid-tie systems. Many Rapid Shutdown solutions turn off the array when utility power is off, which isn't desirable. We have one client with an underground service and the local AHJ wants the RS initiating device near the meter (as our Canadian EC requires) which is hundreds of feet away. In this circumstance but without back-up, we would usually just use an AC disconnect near the meter to initiate RS, but now we're facing the prospect of running a new control circuit all the way back to the pole or requesting a variance.

[RE-wrenches] MidNite SOB problem and possible solution
Season's Greetings Wrenches We have been attempting to use MidNite SOB's with Sol-Ark inverters this year. In Canada we only need one SOB per string since our Code requires Rapid Shutdown for PV source or output circuits more than 1 meter from the array. However, not all the SOB's were closing the circuit when we had two strings on one MPPT - both when we combined two strings on the Sol-Ark PV input terminals or when we used MC4 Y connectors outside the Sol-Ark to combine two strings. MidNite had no solution for this back during the summer and tech support there only suggested that we had configured the system incorrectly or that we shouldn't combine strings that way. This array also had a very long underground run between the array and inverter. So, at that time, not knowing if it was distance, interference from something else or gremlins, we just took out all the MidNite equipment and installed a DC SunVolt Rapid Shutdown box. Diagnosing the problem was a challenge since only one of the parallel strings on each MPPT was not producing power at any given moment. Also, everything worked fine while I made voltage and current measurements but when I pushed the coil and wires into the JB I lost half my solar power. Anyway, today I solved the problem on a new system I was commissioning by wrapping the SOB Transmitter coil, with the positive conductors passing through it, in aluminum foil. I hypothesized that with the coil on the positive conductors, the negative conductors, which were very close to the coil, all of which was inside a metal junction box, were picking up a signal from the coil and this was interfering with the signal on the positive. It's a bit cludgy, but shielding the coil seems to be the solution. I'd love to hear if anyone else has had this problem and/or solution.

Re: [RE-wrenches] fortress power question
My experience and advice from Tech Support at Fortress was NOT to network the eVault 18.5 with only 2 batteries. We just installed two eVault18.5 with one Sol-Ark12K. The communication doesn't work properly with only two batteries. The tech advised to run both batteries independently as Masters, which was the only way we could make it work. All attempts at networking them failed. We didn't try to network the batteries to the inverter. Of course, Murphy's Law dictated that this was a remote system with no internet or cell reception. So, I had to make a second trip out to make it work after I found this out from Tech Support the next morning. Apparently you can network one battery with the Sol-Ark in closed loop but the tech I talked to said how this is done (special com cable) varies with the version of the Sol-Ark one is using since Sol-Ark has been making changes to their circuit board.

[RE-wrenches] Trace DR inverter fan
I have a client whose Trace DR 1524 inverter (yes, it's an old system) fan is running constantly. I haven't been to the site (3 hour drive, 1 hour boat ride) but I am guessing that it's a failure of a temperature sensor. Does anyone have experience with something like this?

Re: [RE-wrenches] Is Solark UL 9540 Certified?
Sol-Ark says it has UL9540 with Simpli-Phi https://www.sol-ark.com/battery-partners/ You should ask for documentation. NFPA 855 and the new electrical code rules are going to change the off-grid market drastically. Not only do you need the inverter and battery certified to work together per UL9540, the charge controller has to be part of the system too - mixing MidNite, Morningstar, Outback, Magnum, Schneider, Victron, etc. components will likely be verboten. To make it more confusing, only one manufacturer - either the inverter/PCU manufacturer or the battery manufacturer gets the UL9540 listing for the combination. Also, there are apparently no NRTL agencies that are equipped or prepared to certify lead acid batteries right now. The size/threshold limitations in NFPA 855 may pose some problems as well, since exceeding them either requires UL 9540A cell level certifications, which few if any battery manufacturers have yet, or I've been told they can be exceeded if a fire propagation study is conducted on site. But I have no idea who would be qualified to do that or how much it would cost. So, it looks like 1 and 2 family dwellings will be limited to 80 kWh of energy storage if located in attached or detached garages and 40 kWh if in utility closets, storage spaces, etc. So, ~800 Ah at ~50V appears to be the limit. And using lead acid batteries seems to be in limbo. We are struggling with understanding the implications in Canada as well. As North America harmonizes standards, UL9540 and UL1973 are actually ANSI/CAN/UL standards and thus apply in both countries. In a nutshell: the inverter/charge controller is listed to UL1741, the battery to UL1973, and the combination to UL9540. Outback systems are UL9540 with SimpiPhi. Schneider Conext systems are UL9540 with Discover Magnum doesn't appear to have any UL9540 battery partners Sol-Ark has a long list on their website. *Eric Smiley,* Project Manager e...@vecoop.ca T: 250.703.6004 <+12507036004> T: 888.386.0116 <+18883860116> *VIRIDIANENERGY.CA <https://viridianenergy.ca/>* * <https://viridianenergy.ca/>* On Tue, 20 Jul 2021 at 11:05, Dave Angelini Offgrid Solar < offgridso...@sti.net> wrote: > Sounds like California Loren? > > I use Schneider and they have UL9540 certs. > > Here is a link to them and yes I have been asked this locally. > > > https://solar.schneider-electric.com/schneider-electric-solar-and-discover-battery-attain-ul-9540-certification-for-xw-pro-and-aes-batteries/ > > > > *Dave Angelini Offgrid Solar > "we go where powerlines don't" > http://members.sti.net/offgridsolar/ <http://members.sti.net/offgridsolar/> > e-mail offgridso...@sti.net > text 209 813 0060* > > On Tue, 20 Jul 2021 10:22:43 -0700, Lorenzo Ortiz > wrote: > > Wrenches, > > We have recently had an AHJ reject our Solark 12k system with Simpliphi > batteries stating: > *"Energy storage systems are required to be listed per UL 9540 per NEC > 706.5 (See also Annex A in the NEC, under energy storage systems).

Re: [RE-wrenches] BP HI / Namaka with Sol-ark inverters
Kirk We tried using SolArk for off- grid applications but stopped for several reasons: - surge on single phase loads - too many firmware updates (i.e. bugs in the firmware or new features that are standard in other inverters) - too many service calls: false positive arc faults, AGS not working, battery over charging,.. - not modular. If one component has an error, it can take out the whole system. - too reliant on an internet connection - hidden settings that aren't described in the manual - including one that could only be accessed via the internet and left a customer without AGS for several months until they hooked up their satellite internet. We thought we were going to have to replace the inverter. We've gone back to equipment that does less and has a longer track record; so we don't feel like we're beta testing equipment with our clients and we know what the limitations are. Tech support has been great and the monitoring is quite good. It just hasn't been reliable enough for full time offgrid. When we compare the service calls for our Magnum, Outback, Conext, Trace (yes we still have two SW systems going strong) and SolArk systems, the initial savings with SokArk disappear. I can't recall the last time I had to repair/service a Magnum system unless it was user error. Keep it simple!

[RE-wrenches] Outback Radian transfer time
I have an off grid system with three GS8048A inverters. Every time it switches from generator charging to inverting - at the end of absorption - the lights flicker and a propane boiler in the house goes into fault. I'm using Advanced AGS on the Mate3S. The loads don't exceed about 6 kW right now. Does anyone know if there's a way to reduce the transfer time? The transition to charging is smooth. I don't understand why it's so clunky transitioning back to inverting.

[RE-wrenches] Sol-Ark arc fault issues
A general question for those who have installed Sol-Ark. We have a handful of systems that have consistently displayed arc-faults that, as best as we can determine, are false positives. Is this something others have experienced? We are trying to determine if this is a general problem with Sol-Ark or if we are having poor luck. Our other string inverter systems are not displaying this problem, which leads us to believe it isn't due to installer error. *Eric Smiley,* Project Manager e...@vecoop.ca T: 250.703.6004 <+12507036004> T: 888.386.0116 <+18883860116> *VIRIDIANENERGY.CA <https://viridianenergy.ca/>* * <https://viridianenergy.ca/>* ___ List sponsored by Redwood Alliance Pay optional member dues here: http://re-wrenches.org 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 There are two list archives for searching.

Re: [RE-wrenches] 3 phase off-grid UL listed
I've worked with a few larger 3-phase Conext XW systems - 3 inverters and 6 inverters. The inverters' output capabilities are slightly reduced since they have to be converted to 120 V, effectively doubling the output current. Also,they required an external transfer switch. Even with 3 inverters configured for 3-phase, I would recommend an external transfer. The relays have a habit of welding. Once they were configured properly, there was no problem starting large HVAC loads and even large single phase loads were OK. *Eric Smiley,* Project Manager e...@vecoop.ca T: 250.703.6004 <+12507036004> T: 888.386.0116 <+18883860116> *VIRIDIANENERGY.CA <https://viridianenergy.ca/>* * <https://viridianenergy.ca/>* On Thu, 8 Sept 2022 at 08:49, Vince McClellan via RE-wrenches < re-wrenches@lists.re-wrenches.org> wrote: > That’s a market segment that no inverter company that I know of really > makes a product for. > I would probably use 3 Sol-Ark 12K inverters. > You’ll have to be careful with load balancing with any Sol-Ark inverter > though. > Schneider would also work but you will have a lot of individual components > and you would need to be careful that the internal transfer switch is > within its 60 amp capacity limit from a generator or other source.

In addition to Frequency/Watt response Voltage/VAR response is also used. https://en.wikipedia.org/wiki/Droop_speed_control Building inverters that mimic the behaviour of spinning generators is a great development as some jurisdictions now require, for example, ride-through capability when brown-outs occur, rather than the older requirement for inverters to simply turn off when voltage or frequency dropped below certain limits, which just exacerbated brown-outs. Essentially an inverter can be programmed to have "inertia" just like a big spinning generator. Larger grid-interactive inverters have done this for a while, with very complex settings, but we are now seeing smaller residential and commercial inverters with similar capabilities. This industry keeps evolving and improving, which is great for keeping us on our toes and I find it very exciting. *Eric Smiley,* Project Manager e...@vecoop.ca T: 250.703.6004 <+12507036004> T: 888.386.0116 <+18883860116> *VIRIDIANENERGY.CA <https://viridianenergy.ca/>* * <https://viridianenergy.ca/>* On Fri, 2 Dec 2022 at 07:08, Windy Dankoff via RE-wrenches < re-wrenches@lists.re-wrenches.org> wrote: > Dear Mike, > > As co-author of upcoming book "The Handbook of Solar Water Pumping", we > have expanded its definition to include micro and national grid-tied > systems in which pumping is synchronized with power availability from PV.

[RE-wrenches] XWPro produces noise at low (<50 W Power)
The inverter produces acceptable noise under no-load and at loads above 50 W or so. The noise (humming/buzzing) increases drastically at low power. So, essentially it makes a lot of noise at night. Has anyone else encountered this? We suspect it is the transformer vibrating - some kind of resonance with the inverter enclosure. But it's the first time we have encountered this. *Eric Smiley,* Project Manager e...@vecoop.ca T: 250.703.6004 <+12507036004> T: 888.386.0116 <+18883860116> *VIRIDIANENERGY.CA <https://viridianenergy.ca/>* * <https://viridianenergy.ca/>* ___ List sponsored by Redwood Alliance Pay optional member dues here: http://re-wrenches.org 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 There are two list archives for searching.

Re: [RE-wrenches] XWPro produces noise at low (<50 W Power)
Thanks. That was the feedback we already received. I think it is SOP for Schneider to tell you to reinstall firmware and reset to factory - no matter what the problem. Fortunately, we have to go back to do some more wor - they are finally receiving their generator. That will give us a chance to recommission the system. *Eric Smiley,* Project Manager e...@vecoop.ca T: 250.703.6004 <+12507036004> T: 888.386.0116 <+18883860116> *VIRIDIANENERGY.CA <https://viridianenergy.ca/>* * <https://viridianenergy.ca/>* On Tue, 6 Dec 2022 at 11:45, Tump via RE-wrenches < re-wrenches@lists.re-wrenches.org> wrote: > I have heard this too.

Re: [RE-wrenches] Off Grid, Cloudy Days, Solar Tilt Question
It is difficult to quantify but this was pointed out to me years ago by a long-time off-grid installer, who also lives off grid on Vancouver Island where weeks of solid cloud isn't unusual. We never tilt to latitude + 10 to 15 for off-grid, as many textbooks recommend. Latitude works quite well. When I've tried modelling it, January is the only month that seems to outperform when tilted at less than latitude, which is often our cloudiest month. We also have a lot of conifers here so tilting to 60 degrees often means the modules are facing the trees anyway. Fortunately we don't get much snow so a shallow tilt is OK. *Eric Smiley,* Design Manager e...@vecoop.ca T: 250.703.6004 <+12507036004> T: 888.386.0116 <+18883860116> *VIRIDIANENERGY.CA <https://viridianenergy.ca/>* * <https://viridianenergy.ca/>* On Wed, 25 Oct 2023 at 17:42, integrityenergy101 via RE-wrenches < re-wrenches@lists.re-wrenches.org> wrote: > This is too funny.

Re: [RE-wrenches] Fortress
The BMS in the eVault Classic has been a headache. Fortunately, we were able to convince Fortress to let us proactively replace the BMS in some of our systems - especially the remote off-grid systems. We are still having problems with weird SOC readings on many of the batteries. Apparently the SOC reading can get stuck at 100% and Fortress is aware of the bug. It is frustrating because the owners rely on the SOC reading rather than voltage. This experience did convince me that Li-Ion in off-grid applications is not a reliable solution unless there are multiple independent batteries with their own BMS. The battery itself may be robust (how long have these actually been in the field in real-world applications) but the BMS is a complicated piece of electronics on which the entire system is dependent. Li-Ion violates the KISS principle. So we talk our off-grid clients out of using Li-Ion. IMHO relying on firmware and circuit boards to keep your system running and protect it from catastrophic failure is not sustainable. *Eric Smiley,* Design Manager e...@vecoop.ca T: 250.703.6004 <+12507036004> T: 888.386.0116 <+18883860116> *VIRIDIANENERGY.CA <https://viridianenergy.ca/>* * <https://viridianenergy.ca/>* On Wed, 14 Feb 2024 at 06:47, Peter Giroux via RE-wrenches < re-wrenches@lists.re-wrenches.org> wrote: > Good morning my fellow wrenchers.

Re: [RE-wrenches] Sol-Ark 15k solar panel frame grounding
SolArk arrays are ungrounded. However, because they are transformerless, when the inverter is operating, there is a reference to ground on the DC side via the AC side neutral bond to ground. So, a ground fault on the AC side will also cause a GF error. Many transformerless interactive inverters are using Isolation Resistance testing to detect ground fault, rather than measuring current. Sol-Ark doesn't have any literature to say what method of GF detection they use, but it is unlikely there is a reference to ground via the GF detection method. In any case, they aren't solidly grounded, and none of the DC conductors should be white or grey, they can both be hot with respect to ground.

Re: [RE-wrenches] Lead acid batteries taking too much current
Our company does not pair any lead acid with a Sol-Ark. Our opinion is that the unit is designed for Li-Ion and that is what should be used. In much the same way that some legacy off-grid products don't play nicely with Li-Ion, we stick with combinations that don't require specialized programming work-arounds that aren't in the manufacturer's manual. Interesting aside, I recently had to service a very old Trace DR system which the client had upgraded to Can-Bat Li-Ion. The service call had to do with the generator but I checked the batteries and charging history. It looks like the DR is so dumb it, it works just fine with the BMS keeping an eye on things.

Re: [RE-wrenches] Outback Optics RE is down again
Same here. I had to defeat my security to access the site. This is worrisome since some of our sites are fly-in or boat access only. In addition, all Outback products lost their CSA listing when they were bought. So we cannot install any of their products - if we could get them - under a permit. We are crossing our fingers we don't have any failures.
