Initially I was thinking despite the generator output not being connected to inverter Gen input, I would use the Gen start dry contacts of the inverter to command startup at a certain state of battery bank discharge, then I realized 53.xx volts would appear on battery terminals, telling the...

Right, my concern really was what the inverter will make of this oddly behaving battery. Since there's no connection or monitoring between inverter and generator. The expected battery discharge would be reversed, I was thinking that may cause some logged error in the inverter.

I have a Luxpower 12Kw inbound, it can do 120/240 split, or 120/208 (2 out of 3 phase legs). I happen to live in a community with a lot of multifamily buildings, so the distribution transformers are all 3-phase output At my single family, 200A residential service, 2 out of 3 phases are serving...

We've got the same shingles! Man are they beautiful. GAF Camelot Williamsburg Slate is my guess. Couldn't bring myself to cover them with panels, ended up using pergola over deck and about to add a vertical wall of shingled bifacials.

Hi, did you ever get to the bottom of this?

Any update on your SunArk experience? I'm buying panels from their sister company Sunevo & considering trying one of their inverters as well

This happened to my LVX6048WP... array voltage present at inverter input terminals... Inverter doesn't register input. Did you ever resolve?

I would go nominal output plus 20%. Consider the double pole breaker as what it is, a breaker for each leg. and your nominal is 25A, so... 30A double pole, or 40A to give yourself some margin depending on what kind of loads you have (pumps, AC compressors). The manual tells you for grid AC input...

I have one. After a week of not accepting 120/208 grid input, finally was told to swap L1-L2 around....successful grid input. Left it under moderate load yesterday (2Kw between PV & grid) and went out, returned to find it beeping with fault code 03, Bus soft start timeout. Basically the code of...

Please explain the mechanism, before I need to use it and break something (:

its still only 120 degrees away from the other leg, just in the other direction, and since its alternating, what does it matter which is 'leading'?..... honestly it escapes me, I'm too old to break open electrical theory books anymore..

I think it was more a matter of input "rotation" because it wouldn't accept AC in even if output was switched off.

FIXED! Not afraid to eat crow.... MPP engineer asked me to interchange L1 & L2.... I scoffed, but did it anyway. Immediate acceptance of grid power!... Now I thought I had a handle on electrical theory, I know phase rotation is a thing with at least 3 phases... but I was sure 2 phases was just...

yep, triple checked. Inverter freq settings & wiring are good, 4 conductors in, 4 out, 8AWG, 40' run (I'm a past Avionics tech, I've rewired & modified heavy jets half my life, so very confident re wiring and setting review) too bad that confidence didn't translate to a specification phone call...

I dunno, looking at the OEM's specs page, I may have foolishly interpreted one of the AC output configs as being an acceptable AC input config: https://voltronicpower.com/en-US/Product/Detail/InfiniSolar-WP-LV-6K-10K If I can find a 208 to 120/240 wall mount on the cheap, I may go that route...
