Inverter_man reacted to kuba.cz in Anern 10.2kW schematicsHere are some schematics that I reverse engineered from Anern Victor Max 10.2kW inverter. Should be very similar to Axpert VM models. Of course, part references and connector pinouts are different. Also ADC and GPIO assignments do not match genuine Voltronic's.
The SCC board schematic is complete - PV boost circuit, voltage and current measurement, AC power supply and bus soft start circuit.
Then there's a schematic of the two power supplies on the main board - this inverter uses an auxillary 150V power supply to start from the battery.
Also a I attempted to trace the analog part of the control/DSP board. This was little bit harder as there were no printed part references on the board. But all op-amps are there, nothing important (for understanding the circuit function) should be missing. [15/Aug/2025 added the remaining "digital" part]
I think there will be some errors, so every feedback is appreciated. I can provide KiCad project files if anyone is interested.
