Hello all, I have a new setup I'm working on, long store ill try to get to it. I have 2 x 100 ah server rack battery connected to my 8kw growatt inverter, inverter output and battery are working fine. its output is split phase 220 volt. all that's good. on the input side ( I'm off grid so no grid ) but I have a single phase honda 2200 I ( for battery charging and testing battery charging now ) connected to a Victron autoformer , output is split-phase 220 volt on my meter at 60 hz but on the inverter screen, it shows as 262 volt which is still below the high voltage cut off (273?) so at first the grid icon would just blink it would not sync. So I had a 500-watt light to the honda to put a load on it and sure enough, it then syncs with the inverter and bypassed power through to the output of the inverter ( off battery use at this point ) but it is NOT charging, the charge light will not come on... So I tried to simulate the grid with a 1500-watt inverter I have ( instead of honda 2200 ) that inverter ( on a different battery bank ) did sync faster and after a min, it went into charge mode( the 8kw inverter ) and started charging the server rack battery . . back on the honda again I even tried bypassing the auto former in case it was the issue but this inverter ( the 8kw ) has to have input split phase it would not do anything on single phase other than run off the battery, so is there a way to force it into battery charger mode ?? Im stumped
