Alright guys I wanted to start a thread to make sure I am not missing anything or there is a better way to go about what I am trying to do. In short I currently have a single 14.3kwh EG4 indoor wall mount battery with a Midnite 12KW AIO and 9 of my 400w Hyperion panels mounted on a south facing array. I am looking to finish the AC side of my system and the main goal is to maintain being off-grid but utilizing the grid as a grid assist function as well as keeping my generator port open for future installation of a full size backup generator to charge my batteries.
Initial schematic of what I am planning to do is attached. System would be expanded further with a 36 panel 400w Hyperion bifacial carport setup as my covered porch next to the garage (where the inverter, batteries, 200amp grid service is located) as well as future additional capacity of more batteries (probably additional EG4 power pros mounted on the garage sill plate) as well as one additional Midnite AIO. Idea is to have a minimum of 60KWH of battery capacity and enough inverting capability to run everything in the house. Thoughts are to gradually expand but have everything wired to where I can simply add capacity as required. Entire system is able to be put back to grid only if there were any solar side failures by a 200amp double throw Siemens MTS that I have already procured. I also have already purchased a Siemens Catalog Number SN4060B1200 Plug on Neutral Main Breaker Load Center and a Siemens Catalog # SN2040L1200 SN Series Main Lug Load center for both combined inverter outputs to feed to then go to the main breaker load center.
*Initial thoughts were to use a chargeverter to directly top off batteries from Grid but I am rethinking that and directly tying in AC in from Grid on inverters*
Photos of said area where all of this will be installed is included. Thoughts are to surface mount the load panels and run a trough between the main grid load center and the additional items. Not sure what I want to do yet with the Tesla Charger. (Excuse the mess in the garage it's been nuts with projects lately). Another idea I am stealing from Adam De Lay is to use Mersen Power Distribution blocks so I can easily combine AC in from Grid and AC out from Inverters when paralleling. Let me know your thoughts and what you may change or feel would be a better solution.
