Hello,
We installed three Quattro 10kW for a three phase system with lithium battery storage. The master inverter's low battery light is on, while on the other two inverters the light is off. Also, on the color control as well as on the battery's display, the battery voltage is 50V (70% SOC).
Can anyone advise the reason for this warning?
In a three phase system only the master shows the status by LED. The other two units are slaves and don't show their status. Check the DC voltage and connection to all three units.
In the 3 phase system there is no one master. All three units are masters for respective phases.
Master and slave exists in the parallel connections.
