5Product Overview
5.1 Brief Introduction
Product overview
AMASS GTX5000 is a battery system with an operating voltage range between
45.6~56.16V. It is utilized in household energy storage applications and works
together with a low-voltage inverter to realize the goal of energy storage for the
home.
AMASS GTX5000 has built-in BMS (battery management system), 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.
Multiple batteries can connected in parallel to expand capacity and power for
larger capacity and longer power supporting duration requirements, AMASS
GTX5000 support up to 4 parallel operation.

L7: Red, long bright if equipment failure or protected.
2、In parallel system, connect the parallel communication wiring according to
section 5.3.1, then long press the start button of the Master PACK, after normal
startup, the battery system will automatically encode and assign ID to each
parallel PACK, and then the parallel system will run normally.
3、Press start button of Master PACK more than 3s and then release the button,
LED will lights from L1 to L7 to shut down the battery module. In parallel system,
the master pack will shut down after all slave packs shut down.

5.3.1 Wiring instructions
Wiring Diagram
1、Power cable wiring instructions
Power cable terminals: there are two pair of power terminals, each pair with same
function.
Single module: Any of the terminals of each pair can be used.
Parallel system:
NOTE: P+ must connect to master pack, and P- must connect to last slave
pack.
Master pack: one of the P+ terminals connect to PCS, the other one paralleling to
another battery for capacity expanding.

Last slave pack: one of the P- terminals connect to equipment, the other one
paralleling to another battery for capacity expanding.
Other slave pack: for each pair terminals, paralleling to another battery for
capacity expanding.
2、Parallel communication cable wiring instructions
Link Port In / Link Port Out communication terminal (RJ45 port) is integrated
with the signal for automatic coding function.
NOTE: The connection order of Port In and Port Out should not be wrong,
otherwise it will lead to the automatic coding failed.
It is required that the Port In of the master PACK do not connected to the
communication line, and the parallel communication wire is connected to the Port
In of the first slave PACK from the Port Out of the master PACK. Then the Port
Out of the first slave PACK is connected to the Port In of the second slave PACK.
The Port Out of the second slave PACK is then connected to the Port In of the
third slave PACK. The parallel system support up to 4 parallel operation, and Port
Out of the last slave PACK do not connected to the communication line.
3、PCS communication cable wiring instructions
The CAN communication port of the Master pack is connected to PCS.
