Volts but no amps on 15 month old panel

[wrighta]

My home made panel was working fine until recently when it stopped reporting to Enphase. I am getting plenty of volts, but zero amps! It is not even powering the microinverter enough to turn on the light.

Any one out there with any idea what I should look at? Plenty of sun when checking amperage (my other home made was kicking out 2.5 amps).

Thanks.

how are you checking
Voc and Isc?

You got 6 months more than expected out of a DIY panel. Water vapor penetrated and corroded the tab terminals so now you have now current from high resistances.

Any ideas for a fix?

Any way to improve this issue?

I have a volt/ amp meter which I connect to the wires just before they enter the microinverter.

Unplug the inverter and check VOC and Isc
