2.1 General System Description
With GMDE GEatom series battery inverters, customers can easily retrofit existing PV system to PV
energy storage system as it is shown in below Figure 1 and Figure 2. GMDE battery inverter has open
interface and is capable of working with all grid-tied inverters. The energy management solutions of
the energy storage systems are described as solution 1 and solution 2.
Solution1: Integrated Energy Management Solution
Through RS485 cable, the battery inverter communicates with the power meter that is installed
between the AC grid and the customer load. With the power-related information sent from the power
meter, the battery inverter can automatically decide how to charge or discharge the connected
battery packs
Note that:
(1)
In this solution, lead-acid batteries can be integrated into the energy storage system without BMS
(Battery Management System).
(2)
If lithium batteries are adopted, an independent BMS is compulsory to maintain battery’s lifetime.
(3)
The power meter used in this application must be confirmed by GMDE first since the integration
of communication protocol between power meter and GMDE battery inverter is required.
