I had intended on building fixed "Stand Alone" solar (ESS configuration with 2KW panels, 3KW inverter, 10kWh Lithium).
Designed in accordance with NEC 690 and 710 "Stand Alone" ....implementing multi-circuit 120 VAC transfer switch (Reliable 10-circuit 30Amp).
Local permitting proving to be expensive and complex for DIY solar (mainly due to required certifications of installer and component requirements above and beyond NEC specs).
So, tossing around idea of implementing Plan-B instead:
Small-scale of system will allow me to implement a portable battery generator solution.
Notable design considerations:
*)Inverter and charge controllers are NOT UL-listed.
*)Conductors fabrication, breakers/fusing, labeling scaled as outlined in general electrical code/best-practices and NEC 710.
*)Designed using "NEC 690 Standalone System" guidance. Considerations include PV&ESS/&Inverter-out disconnects (integrated within generator unit),
*)using 2020 NEC 706 guidance for ESS implementation
*)No grid interconnect (NEC 705?)...is standalone with power transfer (Using NEC 710 guidance) to select circuit (total 125% amps of selected cicuits under rated capacity of generator design).
*)Instead of installing hard-wired 10-circuit transfer switch myself will instead hire electrician to install transfer switch with 30A generator inlet box/connection.
*)10X solar panel array is ground mount solution......pushing through coding/permiting for DIY ground-mount I have not figured out yet......ideas?
Thoughs?
