My off-grid system consisting of a Quattro 5k 48v inverter did some weird stuff for the second time last night.
I suddenly lost all power. The inverter LEDs were showing Low Voltage and Overload.
The Venus GX reported a warning :
Low voltage - 49.59v (which is far from low)
And an error - Overload
This is the second time I have seen this, the first time was over six months ago.
Turning the inverter off and back on resolved the issue.
Here is what I’m thinking (and I’m really only guessing):
If there was a dead short on a house 240v circuit you would of course expect this to trip a distribution circuit breaker, but what if the inverter can not supply enough current to exceed the trip point?
Does anyone know what the inverter will do when presented with a dead short on the output?
Any other ideas what might be causing this?
