60 amps per mppt right? So if I have PV connected to only 1 x mppt and want to charge the battery at say 20 amps, I would need to set program 01 at 40 amps?

The SC48120 has a 7000w PV input limit with 2 independent MPPTs. Does this mean a maximum of 3500w per MPPT, or could you put 7000w to one MPPT and nothing to the other MPPT?

Thanks, I have read through most of this and will continue reading your other threads

I’ve posted my setup. I will also be using 3 x SCC48120

Here is the planned setup. It was only partially commissioned with PV array 1 & 2, Growatt 12kw inverter, and 1 x battery.

I was 30% over on each mppt (4560w)

Okay I am currently using a 250a ZJBENY BDM series breaker https://www.zjbenysolar.com/Molded-Case-Circuit-Breaker/Energy-Storage-Breaker-BDM-series-2487.html

I am still scouring the forum for information so I will try to find kromc5 post

I can easily pull some PV fuses (3S4P per mppt) and get under the 3500w per mppt, but I want to continue researching the possible cause before I fry a 3rd inverter, so I’m scouring this forum for clues. I may start a post for help

I installed a SPF12KWHMV with 4740w 126V to mppt 1 and the same again to mppt 2, based on the understanding overpaneling is fine as long as the VOC limits are not exceeded. I also took into consideration the thermal coefficient factor. We are fully off grid without utility supply. All working...

We’re you able to determine the cause of the DC short?
