Figure 1 GBESS 2.4_4.8KWH System
The system includes four modules: Soldate 3100/3700 TL, BM024 battery manager, lithium battery
packs and energy meter.

Figure 2 Main System Components
1) SolDate3100/3700TL inverter
The inverter converts the DC power from BM024 into AC power. The electricity from battery is used by
the household loads or fed into the grid.
2) BM024 battery manager
In connection with the SolDate3100/3700TL via DC bus line, BM024 battery manager charges /
discharges the battery packs according to commands from integrated energy management unit.
3) Battery packs

GBESS 2.4_4.8KWH system user manual
6
Battery packs stores the energy generated from PV generator. Generally each battery module’s
capacity is 2.4kWh; so two battery modules can constitute 4.8kWh battery pack.
4) Energy meter
Two 1-phase bi-directional energy meters are needed. One is for grid data collection, another is for PV
inverter data collection. With the meter data, the GEatom 103KHF decides when to charge/discharge
the battery packs.
2.2 System Connection
The four main components are connected as displayed in Figure 1, which can not only optimize solar
energy self-use and realize peak shaving, but also protect family from power outages.

3.1 Unpacking the Device
3.1.1 Before Unpacking
All products are thoroughly tested and inspected before they’re packed and transported. Although
they’re shipped in reliable package, damage during transportation could still occur.
It is important to inspect the shipping package prior to the installation carefully. If any external
damage on the package makes you suspect the device could be damaged or if you find that the device
is damaged after unpacking it, report the damage immediately to your distributor or the goods
forwarder.
If it becomes necessary to return the device, please use the original packages in which they were
delivered.
The gross weight of SolDate 3100/3700TL is 25kg, for which BM024 is 10kg. To avoid injury, take the
device by the two holding grips that are visible on the side and take the device out of the package.
Ensure a second person to assist in the unpacking and installation of the devices.

3.1.2 Mounting
1. Don’t install the device in direct sunshine. External heating from exposure to the sun may cause
excessive internal heating. This may result in output power being reduced in order to protect the
internal components from damage.
2. The SolDate 3100/3700TL weights 25kg, the BM024 weights 10 kg. The installation wall must be
vertical and can carry the weight of the devices.
3. Install the GBESS 2.4_4.8KWH in a location where the ambient air temperature is less than 45◦C.
The GBESS 2.4_4.8KWH may reduce its output power if the ambient air temperature exceeds 45◦C
(The cooler the air temperature, the longer the life expectancy of any electronics device).
4. The installation space for GEatom103KHF and battery cabinet, please refer to the device dimension
figure and installation space figure (Figure 6~Figure 8).
5. The system should be installed in a location where is inaccessible to children.
6. The device is designed for indoor installation (IP20).
7. It is recommended to mount the device at eye level to ensure optimum user comfort.
8. Do not install the system on flammable construction materials, in areas close to flammable or
explosive materials.
