The PowMr POW-RELAB 3KU is a 3kW grid-tied solar inverter-charger all-in-one unit integrating a pure sine wave inverter, solar and mains charging. Three operating modes enable flexible energy dispatch, supporting hybrid charging and power priority configuration, with multiple protections, precise alarms, RS232/RS485 communication, and BMS battery management. Suitable for residential and commercial grid-tied energy storage applications.

Overview

Powerful Load-Handling Capability

Flexible energy deployment is achieved through three operating modes, ensuring stable operation of loads while maximizing the utilization of solar clean energy. The energy-saving mode minimizes equipment self-consumption losses. The standard peak power of this inverter is 3 times the rated power, and it has a built-in toroidal transformer, making it suitable for high-load application scenarios.

Compatible with Various Batteries

It combines pure sine wave inverter output with mains or generator bypass output functions, supporting solar charging and AC power charging. The output power and charging power can be prioritized according to actual application needs. The solar inverter supports lithium-ion batteries, LiFePO4 batteries (User Mode), AGM batteries, Gel batteries and Flooded batteries.

Smart BMS for Optimized Energy Efficiency

Real-time monitoring of key battery parameters helps prevent issues like overcharging, over-discharging, and overheating, offering reliable protection for home safety. It provides accurate readings of State of Charge (SOC) and State of Health (SOH), so users can avoid unexpected power outages and plan energy use more intelligently.

Full System Protections

Equipped with advanced multi-stage protection and accurate alarm mechanisms, it offers all-around security for the entire system. Whether dealing with overloads, voltage fluctuations, or unexpected faults, it actively monitors, alerts, and protects to maintain smooth and stable operation at all times.
