So new to the forum, moderator suggested I post picks of our system. Here is what it is, pictures following: 1500 watts roof top solar, Schneider 4048 inverter/charger, Schneider 60/150 SCC, 4 x 2kw 48v Chevy Volt modules powering off-grid cabin in the Rockies. Our desire was for a robust system that would function for many years without "fiddling around" with it. Hence Schneider Conext equipment and lithium modules connected with a Bobolink Red Wing BMS. The 4 lithium modules are connected via a Square D Q panel with a breaker for each module so they can be taken offline one at a time if needed.... the panel also serves as a positive busbar to combine the modules. All negatives are tied into a common busbar. A Conext System Control Panel is mounted in the living area and through that we have the able to make the adjustments needed for our custom system. Rapid Shutdown to comply with NEC codes. BTW.... DIY'ers spend the money to buy the pre-owned system ready to hang on the wall! It took me 4 days to design and build the connecting conduit and after all was said and done, I really didn't save much money! If you will be inspected, you need to do it right... even if you are not you don't want to have a mess of wires with the potential to burn your place down!
I actually don't have a picture of the
Chevy volt modules in their box. It is a 12" x 42" plywood box, no lid, they sit on styrofoam insulation and the box sits 2 more inches of insulation to "help" keep them isolated from the cold floor. Two of the modules have temperature probes taped and insulated on their sides so we can tell what the temperature is of the modules before we commence charging during the winter months. We are headed up to the cabin Tuesday and expect the modules to be too cold to charge for a couple of days. We will be tucking seedbed warmers around them and of course warming the cabin via wood and propane heaters.
