maintaining the inverter.
Before installation:
Check for damage to inverter and package. If you are in doubt, please contact us or the distributor
before installing the inverter.
Before connecting the battery packs to the inverter, check the voltages and ensure that they are
within the limits of the GMDE inverter specifications. Failure to observe these specifications could void
your warranty.
Installation:
Only trained and qualified personnel familiar with local electrical codes may work with the electrical
installations. For optimum safety, please follow the steps described in this manual.
Please keep in mind that the inverter has battery input and AC grid output.
Disconnecting the inverter:
Please refer to “Disconnecting for maintenance” in section 6.1. Note that wait at least 15 minutes
before proceeding, after disconnecting the battery inverter from AC grid and battery packs.
Operating the inverter:
Do not commission the device until the overall system complies with the application-specific national
rules and safety regulations.
The ambient conditions given in the product documentation must be observed.
The machine or installation manufacturer is responsible for compliance with the limit values as
prescribed in the national regulations.
Only persons who are trained and qualified for the use and operation of this device may work on the
device.
Maintenance and modification:
Only authorized personnel are allowed to repair or modify the inverter. To ensure optimum safety for
user and environment, only the original spare parts available from your supplier should be used.
Functional safety parameters:
Unauthorized changes of functional safety parameters may cause injury or accidents to people or
inverter. Additionally,it will lead to the cancellation of all inverter operating approval certificates.

2. Description
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.
Figure 1 Integrated Energy Management Solutions
Solution2: External Energy Management Solution

Figure 2 External Energy Management Solutions
In this solution, a third party EMS (Energy Management System) is required. GEatom battery inverter
is connected to this EMS by RS485 communication cable. The EMS monitors and controls the start-up
and operation of both the PV and battery inverters.. GEatom battery inverter can work with all the
EMS units as long as the communication protocol is integrated. To request the detailed
communication protocol, please contact us at [e-mail].
Note: Maximum Charging current, Maximum Discharging current, Discharging Stop Voltage and
Charging Stop Voltage should be set before commissioning to maintain battery’s lifetime. We
recommend user to set these parameters every time before activate the inverter. In solution1, these
parameters are set in LCD screen see 4.3.4 Battery Setting”. In solution2, these parameters are set by
external commands according to communication protocol through RS485 interface.
2.2 Description of the Device
The GMDE battery inverter is a three-phase transformerless inverter, mainly being applied to
charge/discharge the battery packs, which could help save client’s electricity bill by optimizing use of
energy.
