[RE-wrenches] Outback Radian Generator Charging
Hello wrenches, We just installed an GS8048a Radian build with Mate 3SL controller (no Optics). We are having some with charging from the generator, as the generator charging seems to be limited to about 4500Watts +/- (20amps AC) when charging through the Radian. It is a Kohler 8.5RES generator and we have the AC input limit set to 30amps and the Gen input set to 30amps. The house load is only about 200Watts when we are charging. The system is at 2200ft of elevation, but I don’t know if that makes enough of a difference. The Gen output voltage seems pretty good and holds around 234V-236V while charging. Any thoughts as to why it may be limiting would be appreciated.

Re: [RE-wrenches] Sol-Ark/Fortress charging issue
Howie, Just to add, I have noticed this type of behavior with a Solark system with AGM batteries. It was very clear that the Solark was limiting the charge to the batteries (about 35-40AmpsDC) when the generator was running, but not clear as to why. This happened after a recent firmware update (maybe 2 months ago) on a Solark 12K Outdoor. The Solark tech looks things over, Enabled the “Activate Battery” setting (I do not know what this does), and he may have changed something else but I don’t think so. Anyways after that it started charging at a higher rate again and I believe has been good since. We also have had some ongoing trouble with the Generator turning on and turning off when it’s supposed to…and wishing their was more customization with the Gen settings, as I know others have mentioned before.

Re: [RE-wrenches] Has anyone ever had one of his customers get a note from SolarEdge like this one?
I know everybody is experiencing supply chain problems and it’s over my head as to what’s going on… I have also recently had poor support from Solaredge. Support was good several years back when the company was young, but it’s been getting worse and worse the last couple of years. We have an 11.4KW where the customer is now on his 4th inverter in 4 years. We are still waiting for a replacement after 6 weeks. We also recently had a SE6k stop producing. SE did a firmware update on day one, and that didn’t help. Day #2 we did a “load test”, by turning off all of the house AC loads and leaving just the inverter on (per SE recommendation), still no dice. Day #3 I called in and they are going to send a replacement but no concrete timeframe. This is very frustrating for customers and us as installers when our customers have to wait this long for a replacement, especially during prime producing days of summer. Somehow they are able to maintain a good stock price and some inventory at local distributors(but not in their warranty department). Solaredge’s customer support needs to step up a notch (or two) if they are going to make it through this. The long wait times and level 1 techs are also not so good.

Re: [RE-wrenches] PAE series surge capacity/ power factor ?
I also have a new (7 month old) PAE system with 2-4448 Inverters (stacked) that we are having some strange issues with. The most troublesome issue is the new Rheem wall-hung LP instant water heater/boiler is throwing an Error Code 12 which is supposedly a “Flame Failure”. It’s a brand new installation with new tanks and lines and the gas guys have doubled checked everything. We are now wondering if it might be related to the power supply. The other indications that it could be related are flickering lights, a 12V battery charger (AC plug in type) that won’t work off inverter power (but will when plugged into the genny, and I’m seeing a little bit of wondering in the Hz on my simple Exeltech volt meter. Magnum recommended a run capacitor on the boiler circuit. I installed that on Friday and still had the error code come up 4 times over the weekend. Any thoughts?

Thanks Larry, This would be a 240V to 120V step down configuration correct? So the sub panel would be 120V only?

Re: [RE-wrenches] Load imbalance issues with SolArk?
We have had this issue with a recent installation. It’s a new off-grid house build, and so not many loads to speak of yet, except mainly power tools. The Solark 12K will not start any of: portable air compressor, table saw, and sometimes struggles with a miter saw, which are each 16amps or less at 120V, but I have measured close to 50amps start up for the air compressor and table saw. The air compressor and table saw are 1.5HP each. What helps is if the motors are warmed up, or putting another load on the other leg to balance the inverter’s output. Was thinking we would install a couple of dedicated 120V outlets for “high-current” 120V loads with a PSX-240, stepping down the inverter's 240 to 120. My understanding is this will solve the issue for starting these loads, but not sure if we might run into issues with inbalance down the road... Would be curious to know if there’s another way to balance all of the house loads using the PSX-240?..

Re: [RE-wrenches] Enphase intermittent breaker trippjng
I was just at a site last week where the Enphase branch circuit breaker, outside utility disconnect breaker, and feed breaker in the main panel all tripped simultaneously, and it happened about 1 hour before I showed up onsite. The customer said it had happened 1 other time last fall but that time it was just the 1 branch circuit in the Enphase combiner panel. Interestingly the customer mentioned that he had just washed off the panels, also about 1 hour before I got there. I went on the roof and found that the installing contractor had not put on the Enphase termination caps. 1 string was wire-nutted with regular wire nuts and sitting on the roof, and the roof was damp right there. This was a fairly flat roof. The other micro trunk cable was just cut with no protection at all, tied to the rail… Amos Post Integrity Energy W 802.763.7023 C 802.291.2188 ienergyVT.com <http://www.ienergyvt.com/> Facebook <https://www.facebook.com/integrityenergyllp?ref=hl> > On Jun 3, 2020, at 2:05 PM, Jason Szumlanski > wrote: > > The breaker in the main panel IS tripping simultaneously with one of the > branch circuit breakers each time. > > > > > > > On Wed, Jun 3, 2020 at 12:43 PM Jay <mailto:jay.pe...@gmail.com>> wrote: > A question that keeps nagging me is why do these breakers trip and not the > breaker in the main panel? > Presuming there is a 40 amp in the main > > I would have thought that given all the times the breakers have tripped at > some point that one would have tripped and I can’t understand why not? > > Jay > >> On Jun 3, 2020, at 8:27 AM, Jerry Shafer > <mailto:jerrysgarag...@gmail.com>> wrote: >> >> >> Wrenches >> Looking g at the bigger breaker tripping at the same time is very likely do >> to response time of the breaker nothing more.

[RE-wrenches] Fwd: Well Pump Sizing
I have an off-grid customer who is having problems with his 10 year+ old 1/2hp well pump. It is running and running at 900watts constant and hardly building pressure and even caused the 250amp breaker on his single VFX3524 inverter to trip. He is running the pump at 240V off a x240 transformer and thinking he might need to replace the pump and might want to go with a larger 3/4hp pump for better performance and more future capacity. Does anyone have experience running 3/4hp pumps on this setup? The pump is approx. 200’ down in the well. -- * Amos Post* Integrity Energy O: 802.763.7023 C: 802.291.2188 ienergyVT.com <http://ienergyvt.com/> <http://ienergyvt.com/> <https://www.facebook.com/integrityenergyllp?ref=br_tf> -- * Amos Post* Integrity Energy W: 802.763.7023 C: 802.291.2188 ienergyVT.com <http://ienergyvt.com/> <https://www.facebook.com/integrityenergyllp?ref=br_tf> ___ 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
