just bought a MultiPlus-II 12/800/35 for a small installation in my planned camper.
Today i wanted to test the device but MP-II shows an overload alert when cutting of AC power an switching to inverter mode.
It's just a testbuild with a LiTime 100Ah LiFePo4 battery and no other device connected.
Updated firmware to v502 and used VictronConnect via MK3-USB-Adapter to check configuration an alert messages.
AC throughput works.
Charger starts in bulk mode but with 0A and does not change to absorption or float.
Battery fully charged an voltage is at 13,55V. No powerloss between battery an MP-II connectors. Cables (25mm²) are short with a mega fuse and mainswitch to cut off battery connection.
Configured MP-II via VoctronConnect to LiFePo4 and checked voltage settings.
Any hint is welcome!
