The Solarix Esener 5.5kVA PowerBoard is a factory pre-wired inverter system on one wall-mount board, aimed at homes and small offices that want reliable load-shedding backup now and solar later. It combines a 5.5kVA, 48V Esener pure sine wave off-grid inverter rated at 5500W with a 100A MPPT solar charge controller (145V DC PV input) and up to 100A battery charging. Esquire lists it as a parallel-capable inverter (up to 12 units, single phase). The inverter is pre-wired to an AC/DC-ready DB with a 40A AC UPS changeover, main and UPS breakers, plug circuit breaker, surge protector and DC disconnect fuse, plus an unpopulated DB ready for solar, a Wi-Fi dongle and an emergency plug socket with 2-pin and USB ports. Only four wires go to the home's existing DB, which Esquire says saves around eight hours of installation. Use four 12V gel/AGM batteries or a 48V lithium pack; batteries and panels are sold separately. 1-year limited warranty.
