Key Features

• 【Powerful Performance】This power inverter delivers 2500W of continuous power and 5000W peak power, with a 23.3A operating current and three AC outlets to support multiple pumps or devices simultaneously. It features pure sine wave output with less than 6% total harmonic distortion (THD), delivering clean, stable power that protects sensitive electronics from damage and interference. During a power outage, it automatically switches to battery mode in under 10ms, keeping your pumps running and your basement dry and protected
• 【Real-Time Monitoring】The clear LCD display and LED indicators provide real-time monitoring. You can instantly monitor voltage, power output, battery level, frequency, internal temperature, and real-time protection status (overload, over-temperature, under/over voltage)—so you always know your system's status and can trust it's ready when you need it most
• 【Safety Protection】The InsensVert inverter is built with multiple protection mechanisms. Soft start technology gradually increases power during pump startup, preventing damaging current surges and extending motor life. It also provides over-temperature protection, short circuit protection, over/under voltage protection, overload protection, overcharge protection, battery low/high voltage protection, reverse polarity protection, and a circuit breaker—offering reliable safeguards against potential hazards
• 【Fast Charging】This inverter charger features a built-in 25A three-stage smart charger that recharges a 100Ah battery in about 4 hours. Unlike basic chargers, its intelligent charging algorithm delivers fast, safe charging while significantly extending battery life. It supports a wide range of battery types, including lead-acid (GEL, AGM, SLA, Flooded, WET, EFB) and lithium (LiFePO4), giving you flexibility to use existing batteries or choose the best option for your needs
• 【Easy & Safe Installation】The unit features a convenient 3-pin plug design for quick, hassle-free installation without complex wiring. It includes 3AWG heavy-duty pure copper battery cables (2 ft) that ensure stable high-current transmission for safer operation. The included ground wire provides essential shock protection, preventing electrical hazards in damp environments
