Yeah I called and left a message, I may have to resort to email, I was just hoping some people here have dealt with something like this and maybe had an idea of what could of happened based on the given symptoms. I would much rather figure out the actual problem vs just throwing a very expensive board at it with no clue what actually failed and if it could have been fixed independently. Solark tech is not likely to know the nitty gritty details of the system. Someone who has disassembled/repaired any all in one Inverter might have useful insightEmail Solark, describe the situation and ask if they will repair it and for how much.
A factory reset will reset KWh to 0. If you know the passcode.I don't know of any way of resetting the history to 0kWh. It must be new.
Did you go through the manual of how to program and get it turned on the first time?
Is the pass code unique not default?A factory reset will reset KWh to 0. If you know the passcode.
That seems pretty poor. That's like being able to roll back the odometer of your car before selling it?? LolA factory reset will reset KWh to 0. If you know the passcode.
Battery powering screen is ok (low voltage). Pv powering screen means the connection from high voltage to low voltage is working. Maybe the high voltage bus to inverter is faulting. Lots of capacitors there, so not diy friendly repair.I believe I tried that, I think it still turned on the screen but kept the Inverter board off. Which is weird since it means it is capable of pulling power from battery atleast enough to power itself. I think even PV only had the screen working but staying off otherwise
Lol has anyone actually gotten the password on these forums? I didn't try but it could be 0000 for all I know.That seems pretty poor. That's like being able to roll back the odometer of your car before selling it?? Lol
Capacitors usually blow correct? Blown capacitors in my experience emit alot of smoke and residue and will smell bad in the box forever basically lol. Neither was detected inside this unit from basic opening of panel. Is there some other way the DC bus could fail less noticeable from over voltage? Also not so DIY, working with capacitors is fairly common for me.Battery powering screen is ok (low voltage). Pv powering screen means the connection from high voltage to low voltage is working.

A common mistake with the error codes you stated is someone accidentally connected an AC input source to AC output of inverter.
Usually the AC PWM IGBT H-bridge devices. They often take out the gate drivers also. If they short out, they can also blow out the battery side MOSFET's.Like grid input wires into load output? It's possible... any idea what exactly gets damaged?
This is exactly the kind of info I was hoping for, Thank you!. Have people had luck finding replacement components and soldering new ones in?Usually the AC PWM IGBT H-bridge devices. They often take out the gate drivers also. If they short out, they can also blow out the battery side MOSFET's.
On SolArk's, these devices are buried below several layers of PCB boards on back heat sink requiring removing a couple hundred little screws.
This is picture of a MPP HF inverter that had AC input source hooked up to inverter AC output.

Don't laugh, is the on/off switch connected ?
Mine was reversed, the on/off part worked but not the light because its an LED.

Wouldn't they just freewheel and passively rectify incoming AC into DC and charge DC bus capacitors? The IGBT body diodes in inverter H-bridge look like they form a bridge rectifier.Usually the AC PWM IGBT H-bridge devices.
That, I do not know?Is the pass code unique not default?
Trust me, I don’t want to share the thoughts I had, when I learned that…That seems pretty poor. That's like being able to roll back the odometer of your car before selling it?? Lol
What if the inverter is on and not frequency/voltage synchronized?Wouldn't they just freewheel and passively rectify incoming AC into DC and charge DC bus capacitors? The IGBT body diodes in inverter H-bridge look like they form a bridge rectifier.
Then thing goes BOOM!What if the inverter is on and not frequency/voltage synchronized?
