3000W Off Grid PSW Inverter Charger

Product Overview

The 3000W Off Grid PSW Inverter Charger is a robust power solution engineered for off-grid environments requiring reliable electricity. This dual-function device integrates a pure sine wave (PSW) inverter and a high-capacity charger, converting DC power from batteries or renewable sources (solar, wind) to stable AC power while replenishing battery banks when connected to an AC input. With 3000W continuous power output and 6000W surge capacity, it handles heavy-duty loads commonly found in remote settings, ensuring consistent performance in grid-independent systems.

Features

Pure Sine Wave Output: Delivers clean AC power (220V) compatible with sensitive electronics, including laptops, medical devices, and variable-speed motors, eliminating the risk of damage from harmonic distortion.

High-Efficiency Charging: Boasts 94%+ charging efficiency with multi-stage charging (bulk, absorption, float) to optimize battery health, supporting lead-acid (flooded, AGM, gel) and lithium-ion batteries.

Dual Power Inputs: Accepts DC inputs from 10.8V to 15V (12V nominal) and AC inputs from 90V to 260V, adapting to diverse off-grid power sources and unstable grid connections.

Advanced Protection Systems: Includes overload, short-circuit, over-temperature, and reverse polarity protection, with an auto-restart function after fault resolution.

Smart Monitoring: Equipped with a LCD screen displaying input/output voltage, load percentage, battery status, and error codes for real-time system oversight.

Application

Ideal for off-grid homes, remote cabins, agricultural facilities, and solar-powered workshops. It efficiently runs large appliances such as refrigerators, water pumps, power tools, and small air conditioning units, serving as a primary or backup power source in areas without reliable grid access.
