[RE-wrenches] Battery Backup for Older Enphase Systems
I'd appreciate some ideas as to what backup system designs work well with the older Enhase equipment (M250/215 era). I've tried this at home with a XW4024, but the frequency rise causes the lights to flicker and it is awfully unpleasant. A customer of mine has asked about backup to go with an array that uses M250s and this prompted me to write.

[RE-wrenches] Bergey XL.1 HummmBuzzz
Friends, I've exhausted the Bergey tech support expertise on this issue and I'm hoping someone on the list may have a solution to share. I have a customer with an older XL.1 on a tilt-up tower. The machine has been in place since 2007. I've done some work to it over the years including blades, yaw bearings, painting, slip rings, brushes, rectifier. The machine/property has a new owner who finds the noise of the machine to be objectionable. The original owner also noted the noise, but was not as dogged about resolving it. The noise is best described as a "hummbuzzz" and it happens when the machine rpms have slackened and then begin to accelerate again. The transition causes some kind of electrical harmonic that is not noticeable once the rpms increase. So, if the machine furls out of a high wind and the rpms drop then the noise begins as soon as it un-furls and the blades begin to accelerate. The noise disappears as it comes up to speed. This noise does not happen if the machine is allowed to run unloaded (with the breaker in the off position). Anyway, I'd sure appreciate any thoughts.

[RE-wrenches] 600Vdc Transfer Switch Between Charge Controller and GT Inverter
Hi All, I've been asked to review a GT-BBUS that was installed with a DC to AC ratio of 2.14. The system owner is frustrated b/c his 9.2-kW of PV is bottlenecked by an 80A MPPT (~4,300W). The inverter is a XW-5548 so there is a second bottleneck to overcome even if an additional CC were added. My inclination is to install a GT inverter for half the array and make a separate point of connection. I have considered adding a transfer switch on the PV conductors to allow the owner to toggle between this new GT inverter and the existing CC. I thought that having the option would be of benefit during extended outages with little sun. I'd be curious to know if anyone has had to solve a problem similar to this one and if they were able to find a suitable switch. To-date, I have not located a good transfer switch or breaker assembly with handle-tie etc... Any thoughts are greatly appreciated. -- Matt Sherald PIMBY Energy, LLC NABCEP Certified Solar PV Installer® 304-704-5943 www.getpimby.blogspot.com www.getpimby.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-wrenches] Two MPPT Charge Controllers, One PV Circuit
Hi All, I recently posted a request for suggestions regarding a 600Vdc xfer switch. In the intervening time, I've been out to visit and review the system in question and found that the original installer had been called back and had added a second XW MPPT 80. The installer did not run separate strings to each of the two MPPTs, but instead they split the PV output circuit with split bolts and now feed the two MPPTs from this splice. A Schneider tech whom I spoke with said that this was a safety issue, but was unable to clearly explain why it posed a danger. Can anyone lend some insight? I can imagine how the MPPT function might be skewed, but the wire size of the feeders are adequate for the combined current of the full PV array and the units are producing power. -Matt I'd like to give the system owner advice with t -- Matt Sherald PIMBY Energy, LLC NABCEP Certified Solar PV Installer® 304-704-5943 www.getpimby.blogspot.com www.getpimby.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-wrenches] Enphase IQ and Schneider XW AC Coupling Performance
Friends, About seven years back I connected a dozen M215 Enphase inverters to our battery backup system at home (Schneider XW4024 with 370AH battery bank). The result was something that I would never want to duplicate for a customer owing mainly to the flickering of lights during the daytime when the XW is shifting frequency. I'm curious if the newer Enphase IQ and Schneider XW equipment behave better in an AC coupling scenario. Can the newer Schneider inverters cue the micros to taper their output and are there any downsides to power quality that the customer might notice during an outage? Hoping to glean some real-world observations.

[RE-wrenches] SWWP Whisper 200 - Looking for a Short to Ground
I've got a Whisper that's not performing and I'm putting this out to the group in hopes that someone has had a similiar dilemma. My line to line voltage measurements are the same between the three phases. However, my line to ground measurements are consistent across only two of the phase-ground combinations. The third phase appears to be shorting to ground. I had the tower down and took the machine off to check the split bolt connections at the top of the tower for wear/rubbing. The down tower wiring checks out. I opened the wire access on the machine to double check wire insulation and the wire nut connections. I unbolted the slip rings and checked for any sign of a smoking gun there. Nothing jumped out at me during the inspection and I'm curious if it might be in the spinner assembly. With no tech support to turn to I am hoping that someone in the Wrench community might have had a similiar conundrum at one time. I'd appreciate hearing from you if you have. Many thanks in advance.

Re: [RE-wrenches] SWWP Whisper 200 - looking for a short to ground.
Thanks to all who pitched in and responded to my request for help on the Whisper! Turned out that the problem lay in the down tower wiring. Two legs were shorting to ground. Measuring the voltage of each leg to ground should have provided me with 0V, but I was reading voltage to ground on two of the three legs. I had checked continuity of the down tower wires to ground, but the results did not highlight the presence of a short so I thought the cable was good to go. It wasn't. The short blew the Whisper Controller (as well as a second AMP meter that I had installed). Those familiar will appreciate that we had an old Easy-Wire Power System from World Power Technologies Inc. that we could pull out of retirement. With a new cable and an old charge controller the Whisper is back in action. Thanks to all for your time and suggestions!

They didn't inherit the warranties on prior sales, but at least they have good support staff (like Therese, who used to be the Senior Tech Support Rep at SWWP) and they have parts for sale.

Re: [RE-wrenches] Split bolt
William, We've mostly stopped using split bolts owing to the same trouble you've noted. Stray wire strands can also be problematic. I try to use an insulated tap/connector anywhere that a split bolt might have been used in the past. I think the added expense is well worth it. I also think that proper torquing of the wire connection is easier on something like an Ilsco ClearTap or similar.

I was curious to see how it would work as I have customers with Enphase systems that occasionally contact me about adding a battery backup system. Why do the fluorescent lights and LEDs flicker once the grid power is dropped.

Re: [RE-wrenches] SB -40 Wi-Fi
William, I would ditto your comment about customers who are not adept at computer/network/web being left out by a decision to remove the built-in display. Wireless and networked systems always add a layer of complexity to the installation and commissioning of a system. Setting this stuff up is tedious and I'd argue that it provides limited value to the owner. Less emphasis on WIFI connectivity and more emphasis on a useful built-in display would be my wish for not only SMA, but all inverter manufacturers. As an installer I greatly appreciate having a display that conveys information helpful to understanding the operation of the system. SMA dropped the ball by not providing a User Manual with their 40 series. Try troubleshooting an error without the User Manual. Having all the info in hand and on a screen in front of you makes life in the field a lot easier. You definitely don't want to have to call SMA - that sucks up a lot of time. I have a couple of customers with Xantrex SW series inverters. These older inverters have a built-in display with buttons that allow the installer or owner to check system information and to program variables. I sure like visiting these jobs and I've found that over-the-phone troubleshooting with customers is pretty smooth. Anyway, I'd trade all the web connectivity and wifi capability for a similar built-in display on today's inverters. -Matt On Thu, Dec 15, 2016 at 2:39 PM, William Miller wrote: > Howie: > > > > I have not tried the Wi-Fi capabilities, so I cannot comment on that > aspect.

[RE-wrenches] Hydro Off-grid Battery Sizing
Good morning! I went to bed wondering if the off-grid battery bank sizing rules that I use for PV systems hold true for hydro-based systems. I woke up and I was still mulling this over. My battery bank sizing standard is to use the method outlined in the SEI Photovoltaics Manual. I would presume that since the charging source is fairly consistent (day-to-day and hour-to-hour) that I could then reduce the days of autonomy to 2-days. I'm curious though if anyone has advice for sizing a battery bank for hydro. Any suggestions would be greatly appreciated.

[RE-wrenches] Puzzle: Dryer does not work during FXR battery charging
Hello All, My curiosity was piqued by a recent customer complaint. I'm hoping someone has bumped up against this issue before. The customer has a OB FXR2812 and a 3,000W Honda gen. Her gas clothes dryer runs just fine off the OB inverter. It runs properly on the Honda gen (when the inverter is bypassed) It will not run when the gen is on and battery charging is taking place. All the other AC loads (including the washing machine) run properly during battery charging with the gen. The OB inverter replaced an old Trace unit. The dryer worked as it should with the Trace during battery charging. Any thoughts are greatly appreciated.

Re: [RE-wrenches] PV direct EV charging
Mac, Our car gobbles 11,500W when it's plugged in to the grid. Even if we reduced the charge rate it would still be a heck of a draw - the chargers in the EVs are greedy. I'll be curious to hear if anyone has a solution, but my bet is that you need to give the EV a deep well to pull from (probably deeper than a battery bank or PV array can directly and consistently satisfy). -Matt On Mon, Apr 12, 2021 at 7:55 PM Mac Lewis wrote: > Sorry, I should have clarified, I am interested in EV charging with no > grid available.

[RE-wrenches] Battery Monitor for Li
Hello Friends, I have an off-grid customer for whom I recently installed some SimpliPhi 3.8kW batteries. This is an older system and it has a Trimetric battery monitor that the homeowners have used for years to keep an eye on their battery bank. The SimpliPhi batteries appear to be working fine at the site, but the homeowners feel uneasy b/c the Trimetric is reporting that they are finishing each charging cycle with an amp-hour deficit. The voltage of the SimpliPhi batteries indicate that they are getting fully charged and are doing so fairly early in the AM (solar is the primary power source). I've spoken with SimpliPhi tech folks and their hunch is that the Trimetric is not reporting correctly. They suggested that a Victron BMV-712 would be more accurate at tracking Percent Full etc... Do you folks think that the Victron is better at counting Ah in/out for Li batteries? Or is the Trimetric adequate - do I maybe just need to adjust the settings? Anyway, the implication that the Victron BMV was better at monitoring Li batteries has me curious and I will enjoy hearing what the group thinks.

Re: [RE-wrenches] Head scratcher
Hi Kris, I think you want the "shore power" to feed into a 240V load center on the tiny home. You might have to add this panel as part of the power inlet equipment. I'd feed the minisplit off this 240V panel and subfeed 120V to the AC IN on the inverter. In turn, the inverter can supply a load center with 120V ONLY circuits. -Matt On Tue, Oct 18, 2022 at 1:30 PM Kristopher Schmid via RE-wrenches < re-wrenches@lists.re-wrenches.org> wrote: > Hi All, > > I am hoping that someone on the list can help me think this one through. > > I have a client that builds tiny portable homes.

[RE-wrenches] XW Pro and the spoiled stuff if the fridge
Hi All, I'm writing to ask if anyone else might have run into a similar situation. My customer came home to dead circuits after being out of town for several weeks. They are grid-tied and have a BBUS with an XW Pro. Their PV array is AC-coupled (Enphase IQ7+). When they arrived home all of the critical load circuits were dead. The other circuits were working fine. The internet router was dead. I got called and made a visit. The XW was not feeding AC through to the loads and it was not charging the batteries. Two battery status lights on the XW were illuminated. A value "279" was displayed. The small LED next to the "A" for charging was illuminated. No other green LED was on - no AC1, no AC2, no Event, no Equalize . The batteries had been discharged, but were well above the LBCO. I tested the grid and it was 60Hz with 240V. All good there. There is no SCP. This is one of the early installs with a Gateway and I did not have computer stuff to get a look at any codes or other status info. Perplexed, and a bit frustrated, I turned off the main DC 250A breaker and let it sit for a couple of minutes. Then I turned the breaker back on and the XW worked just as one would hope - the grid connected through AC1 and, in turn, powered the critical loads and began charging the battery. I thought that I would be able to find some answers once things were back online and I got home to the office where I could look at Insight and Enlighten. Looking at the Enlighten data I could see that production had ceased ten days prior to my visit. Insight has no recorded Alarms/Warnings/Events for this time period. The XW load and battery discharging data show very little draw throughout the period which makes me believe the AC loads were not powered and the battery drain was attributable to idle consumption of the XW, Gateway and Battery Monitor. A series of thunderstorms coincided with the loss of data reporting. The neighbors, when asked, offered that they had lost an internet router to the same storms. They said that they didn't recall a power outage, but their router was cooked and their PV system (Enphase) had stopped working requiring them to contact tech support. My gut is that a surge on the Gateway's CAT cable triggered the XW's relays to open and stay open. The system seems to be working just fine now and doesn't appear to have suffered lasting damage. Not so for the venison in the freezer. I'd love to hear from anyone who may have had a similar experience with the XW or who feels like they have a fair guess as to what caused the problem. -Matt -- Matt Sherald PIMBY Energy, LLC 304-704-5943 ___ 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.
