I may have really goofed.
I bought 4 Longi 355w panels that were rated for 12, 24 or 36v and a combo inverter/controller. I hooked them together in series parallel with multiple 2 foot y cables with mc4 connectors. I didn't have any combiner connectors. So some of the connectors are partially empty. I measured the volts coming off the main wires where they would connect to the controller around 1700 watts on a smoky day where we had no sky/sun showing due to heavy smoke cover.
I then put ring connectors on the pos and negative and attached them to the combined controller/inverter. I didn't hook any batteries up yet. I didn't plug the combined unit into any electrical outlet. I switched it to on and nothing happened.
A day or two, later I went down to finish hooking everything up to the batteries. I checked on the volt meter the watts coming in off the panels and it was around 85. I went out and checked for loose wires and found some were not tight and tightened them. Still the meter reading was fluctuating around 85. I cut the rings off and checked the output on the end of the wire. Still fluctuating roughly around 85. If I disconnect the mc4's after covering up the panels, can I measure the watts somehow with the MC4's on the wires?
We had a clear and sunny day in between there. Did the output exceed the all in one unit? Did I fry everything? Is there a way to repair?
Here's the info on the all in one controller/inverter:
And info on the panels:
DC/Charger Volt Compatible 12v, 24v, 48v
