Inverter has been cycling on/offline recently for no reason when there is plenty of sun available. System starts generating up to about 1KW, then cycles off. Then comes back online, climbs back to about 1KW, then goes offline again. this cycle just keeps repeating throughout the day.

Just started happening recently, the system has been running fine for a few years and this is the first instance of an error condition. (No ground fault indicated on system panel, or anything burnt, marred etc internal on PCBs)

Comments

This sounds like a possibility.  Can you tell me the location of your system (for weather reference) the inverter make/model, module make/model, the number of strings and modules per string?  I may be able to evaluate what is occurring from that data.
