Recommendations for best way to create my strings (9 panels per string, 2 strings per mppt - Sol-ark 12k) Arrays are facing south, those trees are to west running south west south

On page 51 of the current installation manual it shows a bypass transfer switch. If the inverters are wired this way and their is a grid outage, you will need to manually change the bypass switch in order to have power with the grid down. Wouldn't this be better served with an ATS if you do not...

Does anyone add fuses between panel strings and a DC disconnect (IMO switches)? If so, are there any ready made solutions out there?

I have a 400A service to my property (small farm, milling machine, lathe, welders, band saw) I'm trying to work up a wire diagram utilizing a 400a ATS, 2 - 12k sol-ark inverters 26KW array, and a 4kw ac coupled enphase array. Ideally i want my solar arrays powering both of my 200A main...

Looks like Muller industries has disappeared. I'm creating a 48v series parallel battery bank with 20 batteries. So other than the Thunderstruck unit, are there any other options out there for a usable BMS? I've read that the factory HV BMS units can be reprogrammed, but haven't found any info...

I'm creating a 48v battery bank with 20 Valence batteries to connect to my 2 12k sol-arks inverters. What are my best options for combining the 5 battery strings together?

Just found this forum. I'm in the process of installing my PV system (2) 12k sol-ark inverters, 26kw of panels. I've got (20) U27-12xp batteries and interconnect cables from the smith trucks to make (5) 48v strings. How are you guys combing your strings in parallel? Busbar, midnite solar...
