We are in the process of installing and commisioning a 10Kw system on a council building. We have two strings of 20 modules.
When we tested the strings we were getting 694 and 692 Volts and 5.8 amps - clear sunny day - all looked good.
However, during the afternoon one of the strings managed to burn out its DC isolater? We disconnected the load and checked the connections etc, all seemed ok - so we assumed a faulty DC switch. But, when we reconnected after about an hour it did the same?
Any thoughts?
Cheers.
