Thanks, Vincent. This is the information I needed. I did read that at least 1 MCI is needed even if you do not require RSD. The MCI instructions are a bit confusing. I know for RSD you need one at the start of a string and at least one every three modules, but it's unclear if you need the MCI-1 o

It's expensive, but I second Jerry's recommendation. With three subarrays, you should look at the Sol-Ark 15K with three MPPTs. The wiring is so clean with this inverter in most circumstances, even on a retrofit. I am getting more and more comfortable with EG4 LL batteries, mostly out of necessity
