800W 1000Wh Balcony Energy Storage System-Residential ESS-DEMUDA

800W 1000Wh Balcony Energy Storage System

Product introduction

This balcony energy storage system is a plug-in small distributed photovoltaic energy storage solution suitable for home balconies. It consists of a 1024Wh (51.2V) DEMUDA energy storage battery pack, an EM800W grid connected micro inverter, and a 1600C energy storage host. The battery pack has IP65 waterproof, multiple electrical protections, storage, transportation, and sleep modes, supports CAN/485/4G communication, inverter IP67 protection, can dock with two photovoltaic panels, has a complete set of grid connected protections such as islanding, over temperature, overvoltage, and undervoltage, and supports parallel connection of multiple machines; The entire system can achieve photovoltaic power generation, battery energy storage, and grid connected output linkage. When multiple batteries are connected in parallel, priority is given to the batteries with fewer cycles for charging and discharging. Paired with an APP and cloud, it can achieve 30 second level data reporting, daily/monthly/annual power generation statistics, fault alarms, and historical problem tracing. The equipment automatically synchronizes the time when powered on, and can automatically restart after fault conditions are restored. It is easy to install and suitable for balcony self use scenarios.
