Make sure that the
mounting bracket is
inserted into the slot.
Step 4:
Fix the inverter to the wall mounting bracket using the screws from the accessory bag.
Step 3:
Install the inverter on the wall
mounting bracket.
If equipped with a hand, please install the
handle to the inverter, then as shown in the
figure below Inverter to hang in the back flip
chart.
4.3 Electrical Installation
4.3.1 AC side lines connection
1. Measure the voltage and frequency of the grid access point, determine the grid specifications
conform to the inverter.
2. Suggest add the circuit breaker or fuse on the AC side. The specification of it is 1.25 times of
AC output rated power.
3. The inverter of PE line (ground) must be reliable grounding, ensure that the impedance
between the zero line and ground wire is less than 10 ohms.
4. Inverter and mains connection of the circuit breaker or fuse should be disconnected.
5. It is recommended to use copper wire, if you need to use aluminum wire, please consult the
inverter manufacturers.
6. Follow these steps to connect the utility and inverter.
7.If the diameter of the cable does not match the terminal, or if the cable is aluminum cable,
please contact after-sales service.
Two mounting holes in the middle of the wall-mounted bracket are only used for single
column installation, other environments may not be used.
Step 1:
Select and strip appropriate AC cable following the specifications below.
GEP12~20-L-10&GEP25~36-10:
10~25mm². Copper cable with area of
16mm² is recommended.
GEP30~35-L-10&GEP50~60-10:
35~50mm². Copper cable with area of
35mm² or aluminum cable with area of
70mm² is recommended.

Step 2:
Remove the nut of the delivered
AC cover, then thread the AC cable
through each part as shown below and
tighten the parts.

Step 3:
Take the terminals out from the
accessory bag and press them on the
conductor.
Press the terminals against the cable.
Perform insulation protection.
