2000W Sump Pump Battery Backup System, UPS Inverter with LCD Screen — Open-Box, 20% Off

Ultra-Fast Switchover: This UPS power inverter delivers 2000W continuous / 4000W peak, easily handling high-startup loads for dual sump pumps. Auto-switches from grid to battery in just 10–15ms, keeping your sump pump battery backup running seamlessly during blackouts, storms, or hurricanes – no interruption, no flooding.

23A Fast Charging: Built-in 23A charger fully charges a 100Ah battery in just 4.3 hours – 4.6x faster than ordinary inverters. Features 3-stage smart charging (bulk/absorption/float) for speed and safety, preventing battery damage. Operates on 12V with 9.6–16V wide range; low-voltage cutoff and over-voltage protection safeguard your pure sine wave inverter and battery backup sump pump kit.

Full Protection: Six protections over-temp, over-current, over/under-voltage, short-circuit, and overload. Dual cooling fans activate above 45°C. Below 500W load, fan noise is just 30dB – whisper-quiet. Even at full cooling, noise is only 65dB, quieter than standard 75dB designs – ideal for basements where quiet sump pump battery backup matters.

Premium LCD & Build: Bright color LCD shows real-time voltage, power status, battery level, and fault codes. Durable aluminum-alloy housing provides superior heat dissipation and impact resistance. Dual AC outlets let you power two devices simultaneously – perfect for a pure sine wave inverter serving both sump pump and other critical loads.

Pure Sine Wave: True pure sine wave inverter technology works flawlessly with all pump types and sensitive electronics. Ultra-low noise, heavy-duty construction, and comprehensive protection make this the reliable UPS power inverter for basement flood defense. No pump shutdowns, no motor damage – just stable, silent, nonstop protection.
