2.1 General System Description

GMDE Powervortex series hybrid inverters are designed for customers to build new PV energy storage
system as it is shown in below Figure 1 and Figure 2. GMDE all-in-one designed hybrid inverter
integrates both solar inverter and battery inverter. 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 hybrid 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 hybrid 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 hybrid inverter is required.
