This morning the sun was shining and my PV output was near 0. I went to check and inverter was in bypass mode (no PV no Batt supplying the load). You would expect bypass mode in case of a) inverter overload of some kind or b) batt undervoltage and PV not available.
I rebooted the system with no luck. I turned off grid and it kept supplying the load with PV and batt no problem. I turned off batt and it kept supplying the load (500w at that point), but as soon as I turned grid back on, it went to bypass mode again.
The only way I was able to make it go to hybrid (grid+pv supplying the load and pv excess energy exported to the grid) was to change to UPS mode. After that, PV power jumped from 0 to 7kw therefore supplying the load and exporting the rest to the grid.
I switched to APL days ago with no issues at all.
I know must people dont want to feed excess energy to grid but for me, it works pretty well to lower my bill. That's why I want full PV power all the time and not just to carry the loads.
UPS mode did the opposite after power outages... inverter didn't want to switch from solar+batt only to hybrid even at night, only.a reboot would fix that.
