We have connected a three phase 5KVA multiplus-II system.
the inverters are updated, now we want to configure them, we doing so without wiring the AC in but with the 480V battery wired up.
when we switch on the first one its ok but when the second one is switched on it starts beeping and the "absorption LED" lights up same with the third inverter, and we get error code 3.
Any assistance will be appreciated.
