The Esener 3kVA PowerBoard Mini is a factory pre-wired backup and solar kit on a single wall-mount board, put together for Esquire by system engineers and electricians to cut installation time. It pairs a 3kW, 24V Esener pure sine wave off-grid inverter with a 60A MPPT solar charge controller (145V DC PV input) and 80A maximum battery charging, already wired to a ready DB board. The DB includes the main breaker, UPS breaker, 40A AC changeover switch, plug circuit breaker and surge protector, plus a DC fuse holder for battery protection. A built-in plug socket with 2-pin and USB ports gives you emergency power at the board itself. Because it is pre-wired and tested, Esquire says only four wires need connecting to the home's existing DB, saving about eight hours of installation work. It is a good fit for a small home or office: add two 12V gel/AGM batteries or a 24V (25.6V) lithium pack, and solar panels or a Wi-Fi dongle later. Batteries and panels are not included. 1-year limited warranty.
