Pure Off-grid ESS Networking
The pure off-grid ESS consists of the PV strings, LUNA2000 batteries, inverter, AC switch, and load. In off-grid mode, PV strings and batteries must be configured.
The pure off-grid ESS supports only a single inverter and does not support parallel connection of inverters.
Optimizer is not supported in the pure Off-grid ESS Networking. Otherwise, the system may fail to start.
