After changing out my 10 gauge wire and connectors that connect one array to the next, I am hitting 700 watts with light on/off cloud cover. I am going to inspect my wire and connections I removed to see if I can find the fault.

I found a loose fitting mc4. The metal contact wasnt able to lock into the connector as designed. This could have caused a bad connection by allowing the crimped contact portion to back out of the connector when pushed together to make a connection. Producing 650-700 watts now. I made the mc4...

I agree. However, this was a few weeks ago that I was able to get 720watts. Is it possible that a panel could have become comprimised since then?

Also, I tried to go back to all parallel as a troubleshooting step and still got 550 watts max. Oddly, I can hit the 550 watts before noon and stay there until around 5pm.

I'm understand. This has occured across two controllers despite soc. Currently, my mppt outputs this wattage during bulk charge ( correct term?) mode. I recently ran my lifepo4 bank down to bms low voltage. During the charge time back up, it displayed 550 watts. I'm going to check my...
