The system includes three main parts: Hybrid inverter, LFP battery packs and energy meter.
A
B
C
Figure 2 Main system parts
A. Powervortex 309KTL solar battery hybrid inverter
The hybrid inverter converts the DC power generated by PV into AC power. The generated
electricity from PV is used by the household loads, charged into the battery packs or fed into
the grid.
And the inverter is charging / discharging the battery packs according to commands from
integrated energy management unit.
B. Battery cabinet
Battery packs, an on-/off-grid auto-switching component and system Terminal Box are all
integrated in the Battery Cabinet as shown in Figure 2B.
Battery packs stores the energy and discharges it if necessary. In this system, the standard
nominal capacity is 14.4kWh with 6 battery modules in string connection; a high voltage battery

controller is adopted to manage those battery modules and communicate with hybrid inverter.
C. Energy meter
The 3-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 System Installation
3.1 Unpacking and Install Preparations
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 pack them in the original packages that
they were delivered.
3.1.2 Before 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 de-rating to avoid damage on
internal components
2. The Powervortex 309KTL hybrid inverter weights 55kg and Battery Cabinet weights roughly
200kg. The installation wall must be vertical and the floor must be solid to carry the weight of the
devices
3. Install the GHESS 9.8-14.4-TH in a location where the ambient air temperature is less than 45◦C.
As in the system, the inverter may derate the 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. Please refer to the Figure 3 to Figure 4 with regards to the installing space for GHESS 9.8-14.4-TH
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

3.2 Mounting
3.2.1 Mounting Hybrid Inverter
Choose an adequate location and clearance. Drill holes for the mounting bracket in the wall.
There are only two steps to mount the inverter. The first step is fixing the wall bracket and the
second step is mounting the Powervortex 309KTL. All the steps are shown below by the form of
illustration.
The wall bracket can be fixed to the wall by four expansion bolts (M8*12mm: thread diameter is
8mm, nominal diameter is 12mm). Select the appropriate screw types and dimensions for the
wall material is very important.
Mount the wall bracket according to the following steps:
1. Mark the installation position of wall bracket
2. Remove the wall bracket and then drill installation holes
3. Fix the wall bracket on the wall with screws
4. Tighten up all the screws
Figure 9 Inverter wall bracket mounting
Mount the inverter on the bracket with the following steps:
1. Put the inverter over the bracket and move it in horizon direction
2. Insert the hook on the bracket into in the slot behind the inverter
3. Slowly move down the inverter and hook it on the bracket
4. Fix the inverter on the wall bracket tightly
