Figure 1 GHESS 3.7-4.8-SL hybrid system
The system includes three modules: Powervortex 3700TL hybrid inverter, lithium battery packs
and energy meter.
A
B
C
Figure 2 Main system components
A - Powervortex 3700TL hybrid inverter
The hybrid inverter converts the DC power generated by PV modules into AC power. The
generated electricity from PV is used by the household loads, charged into the battery packs or
fed into the grid .
B - Battery packs
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.
C - Energy meter
The 1-phase bi-directional energy meter is for data collection and communication. With the
meter data, the hybrid inverter decides when to charge/discharge the battery packs.

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 Powervortex 3700TL is 35kg. 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 Powervortex 3700TL hybrid inverter weights 35kg. The installation wall must be vertical and
can carry the weight of the devices.
3. Install the GHESS 3.7-4.8-SL system in a location where the ambient air temperature is less than
45◦C. The GHESS 3.7-4.8-SL 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 install space for Powervortex 3700TL and battery cabinet, please refer to the device
dimension figure and installation space figure (Figure 5).
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.
