Hi, wonder if you can help.
I have an Axpert 5KW 48V inverter with with 9 x 270W PV connected in an array of 3strings with 3 panels in each string.
I measured each string, got 107V with 7~8A per string.
But measuring the leads connected to the inverter there is 107V.
But the Amps reading on the inverter is intermittent, jumping from 0A to 6A.
Can you shed some light on this.
Not sure what other tests I can do.
It almost looks like there might be a problem with the Inverter PV controller.
Pleas advise.
