2. System Overview
This manual describes the installation and operation of the GHESS series solar battery hybrid
energy storage system (HESS). The GHESS series hybrid energy storage system is designed and
developed by GMDE Technology Ltd. and can be widely used in residential applications. In which,
the GHESS 5.0_6.0kWh refers to a solar battery hybrid system with 5.0kW nominal AC output
power and 6.0kWh lithium-ion battery capacity. As the battery module adopted in this system is
150V20Ah cell, this system is battery capacity extendable with each step 3kWh (150V20Ah).

3. Installation
The system is very easy to install. Insert the battery modules and hybrid inverter into the system
cabinet according to the following steps in Section 3.2 Install the battery packs and Section 3.1
Install the inverter; finish the output line connection according to Section 3.3 External Line
Connection; check and then the system installation is done.
3.1 Install the inverter
Please follow these steps to install the inverter into the system cabinet:
1) Align with wall bracket, move Powervortex 305KTL hybrid inverter in horizontal direction to
proper position;

2) Make the hook on wall bracket insert into the hole on the back of Powervortex 305KTL hybrid
inverter;
3) Slowly lower the hybrid inverter , ensure the device hang on the hook of wall bracket;
4) Check if the hybrid inverter is properly fixed on the wall.

3.2 Install the battery packs
5) Insert the battery modules into the system cabinet, as shown in Figure 6;

Figure 6 Battery installation
2) At the back side of the cabinet, connect the hybrid inverter, Battery Control Box and battery
modules with the lines as shown in Figure 7; the detailed DC line connection between inverter
and battery packs are illustrated in Figure 8. (The battery packs are connected in parallel, which
means the final battery pack equals to 150V/40Ah)
