I'm needing to find the Open Circuit Voltage and the Short Circuit Amps.
There are two strings going into the combiner box. Each string has 7 modules. I'm fairly certain I'm needing to open the combiner box and do the tests there for each string.
Finding the Open circuit Voltage is pretty simple: Positive to Negative with a DC tester. However the Short Circuit Amps is my concern.
How do I perform this test? I'm thinking I connect the positive and negative wires together then use an Ammeter.
Any advice would be appreciated.
Thanks!
