Quattros not charging batteries from AC1 connected to generator. AC2 grid connected.

Good day,


I'm from South Africa where our grid power is very unreliable. We've installed three 10kVA inverters which supply three phase power from 30kW solar panels on the roof and a 24kW lithium battery bank. We have connected the grid to AC input 2 and the generator to AC input 1. It is a 31kVA generator.

Our problem is that when the grid power fails and the generator starts up, the inverters either does not accept the AC input, or does not charge the batteries and only runs the loads. How can we configure the system such that the batteries can be charged through AC1 with the genset running?

I've tried looking at previous forums and found some information regarding weak AC input, accept wide input frequency and dynamic current limiting. All these have been applied to no avail.

Please help if you can.

Regards

Gawie

Sometimes the wave form from the generator is too distorted.

Also check the grounding for it.

The other thing maybe the powercontrol is stopping charge from the generator as there is not enough input current set to charge and run loads.

Does it happen if the system is in charge only?
