3000W Sump Pump Battery Backup System with LCD Display for Emergency and Power Outage, Pure Sine Wave Inverter, Auto Switches for Grid and Battery

This sump pump battery backup provides up to 3000W power output and up to 27.5A current output, supporting multiple sump pumps at the same time. The high-efficiency power inverter produces a stable pure sine wave 120 VAC waveform, delivering clean power similar to grid power and preventing harm to electrical devices. This battery backup includes ultra-fast (<10ms) automatic switching between grid power and battery backup. Under normal power conditions, the battery automatically recharges; during a power outage, the backup inverter switches over seamlessly, ensuring continuous pump operation and protecting your basement from flooding. The sump pump battery backup system includes a built-in 30A charger that supports rapid charging for most common battery types. It also features overcharge protection once the battery (sold separately) is fully charged, the unit switches to trickle charging to maintain it safely. Equipped with a circuit breaker that quickly cuts off power to the circuit when a ground fault is detected, preventing electric shock. It includes an industrial-grade smart chip with overload, short circuit, over-voltage/under-voltage, over-temperature, overcharge, and reverse polarity protection. No rewiring required. Simply connect AC and DC cables, then plug in. Standard 3-pin design prevents wiring errors and electrical risks. It can be mounted flat or on a wall. Setup takes under 10 minutes
