5Product Overview
5.1 Brief Introduction
Product overview
The AMASSTORE GTX3000 high-voltage lithium battery energy storage system
consisting of 4-10 pcs battery modules (51.2V / 50AH) and one BCU(Battery
Control Unit) in series with an operating voltage range between 180V—700V. It is

utilized in household / commercial energy storage applications and works together
with a high-voltage inverter to realize the goal of energy storage.
AMASSTORE GTX3000 has built-in BMS (Battery Management System, include
master BMS in BCU and slave BMS in battery modules), which can manage and
monitor cells information including voltage, current and temperature. What’s more,
BMS can balance cells charging to extend cycle life. BMS has protection
functions including over-discharge, over-charge, over-current and high/low
temperature; the system can automatically manage charge state, discharge state
and balance state.
AMASSTORE GTX3000 have soft-start circuit, so AMASSTORE GTX3000 can
support inverter without soft-start function, and also can support multiple battery
system connected in parallel to expand capacity and power for larger capacity and
longer power supporting duration requirements. AMASSTORE GTX3000 support
up to 8 parallel system operation.
AMASSTORE GTX3000 supports independent charging of each subsystem of the
parallel system. When one subsystem is fully charged, the other subsystems will
continue to charge until all subsystems are fully charged.
AMASSTORE GTX3000 could support the black start function of compatible

inverters. The ways to trigger this function are different when the battery systems
are operated with different inverters.
