Newly installed MultiPlus 12/1600/70-16 230V enters alarm when powered up. 230Volt AC-In connected and 2 x GEL 110Ah connected in parallel (12Volts)
When MultiPlus is switched on the inverter comes on, fan runs for about 2 sec then switches off and alarm LED is ON.
Trouble Shooting Table just says "Check the table for the appropriate course of action)
Where I purchased the MultiPlus, they don't know either!
