【EXCELLENT PERFORMANCE】 MWXNE sump pump battery backup delivers up to 3000W power output and up to 27.5A current output, supporting multiple sump pumps simultaneously. The high-efficiency power inverter generates a stable pure sine wave 120 VAC waveform, ensuring clean power comparable to grid power and preventing damage to electrical appliances.
【AUTO SWITCHOVER】 This battery backup for sump pump features 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 seamlessly switches over, ensuring continuous pump operation and protecting your basement from flooding at all times.
【CHARGING MODE】 The sump pump battery backup system features a built-in 20A charger that supports rapid charging for most common battery types. It also includes overcharge protection — once the battery (sold separately) is fully charged, the unit switches to trickle charging to maintain it safely.
【COMPREHENSIVE SAFETY PROTECTION】 Equipped with a circuit breaker that quickly cuts off power to the circuit when a ground fault is detected, preventing electric shock. It features an industrial-grade smart chip with overload, short circuit, over-voltage/under-voltage, over-temperature, overcharge, and reverse polarity protection.
【EASY PLUG-AND-PLAY INSTALLATION】 No rewiring needed. Simply connect AC and DC cables, then plug in. Standard 3-pin design prevents wiring errors and electrical hazards. Flat or wall mountable. Setup takes under 10 minutes.
