Product Description

This all-in-one device uses clean energy and supports solar charging, allowing you to fully utilize renewable energy, reduce carbon emissions, and contribute to a sustainable planet.
The built-in high-definition LCD screen displays the remaining battery power, input/output power, and estimated usage time in real time. The mobile application also supports remote monitoring of device status, customized charging/discharging modes, and firmware upgrades for continuous performance optimization.

Say goodbye to cumbersome cabling and device configuration! This all-in-one device seamlessly integrates a high-performance inverter, a long-life lithium-ion battery, and a smart battery management system (BMS). Its lightweight and portable design lets you enjoy instant power anytime, anywhere.
It features comprehensive overvoltage, overcurrent, overheat, and short-circuit protection. The advanced BMS ensures balanced operation of battery cells, effectively preventing overcharging and over-discharging, and ensuring safe and stable operation even in extreme environments.
The wiring between the inverter, battery, and BMS is pre-installed at the factory, and on-site installation takes only 1-2 hours (performed by a professional electrician). It connects to solar panels via standard MC4 connectors and to your home distribution panel via pre-wiring terminals—no complicated splicing or configuration required.
