I have an east/west roof. 42 panels going into a Sol Ark 15k with 3 MPPT inputs. Plan is for all three strings to be 7s2p, but then one of the strings will have both east and west facing panels (10 east, 4 west). If I'm using optimizers (RSD at the panel is a requirement, so I need to use them)...

Choosing between the Sol-Ark 15k and EG4 18Kpv. When wiring the panels to the inverter (to the MPPT inputs), each input has voltage and amperage limits. The Sol-Ark also has a limit of 6.5kw per MPPT. I'm trying to see if they will work with my 42 panel, 17.64kw pv array. After doing some...

Planning out my system and would like to use EG4 batteries here in California. No EG4 products are listed in the approved battery list. I'm guessing, but I want to make sure, that means I can't use any of their batteries in my system plan and get it approved here?

I'm installing a relatively large system with 42 420v REC panels. I'm having a new roof put in and they're going to install all the mounts for me. I'll be installing the rails/wires/panels etc. Since I'm new to this, I'm looking for ease of use, but I'm also being very conscious of the...

I'm already drilling into my roof about 80 times for the solar mounts and I really don't want to make any more holes for conduit mounts. So, two questions. Are conduit mounts even needed? If so, do conduit mounts have to be screwed into the roof or can I just use risers to keep the conduit off...

So I'm planning my solar system and I believe I've sized it correctly. The plan is for a 18kw panel array, and a 30kwh battery and an all-in-one charger/inverter with grid features. Right now I'm planning on the EG4 18kpv with either the EG4 server rack batteries or a pair of the EG4 Powerpro...
