GS7048 Inverter Shutdown

Post by Oncherex » Thu Jan 23, 2020 7:20 am

I have a stacked of 2 of 7kw outback inverters, on optics showing low soc while the other inverters using same batteries are not displaying this same error message. This will cause the inverter to shutdown.
I need an explanation to this cause and possibly a solution.Thanks

It sounds like you have other inverters connected to the same battery as your GS7048's. Is that the case?

More detail on your exact system configuration would, as Jerry Macguire once famously said, "Help me, help you". :grin:

Are your Low Battery Cut Out Settings the same voltage?
