Recently bought above secondhand to add to other Victron kit in campervan. it won’t work. When powered up from batteries all 3 leds flash briefly ( when switching on to inverter or charger) and then go off and unit won’t work. Victron Connect recognises unit using mk3 cable. Screen shows no output frequency. So unless anyone has any ideas I may have to sell this unit for parts and buy a new one- expensive.
