3 Installation Environment Requirements

1) Do not install the inverter on the structures constructed of flammable, thermolabile or explosive materials.

2) Ensure the inverter is out of children's reach.

3) The ambient temperature should be between -30℃~ 60℃.

4) The humidity of the installation location should be below 100% without condensation.

5) Do not install the inverter outdoors in salt, sulfur or other corrosive areas.

6) Prevent the inverter from direct exposure to sun, rain and snow.

7) The inverter should be well ventilated. Ensure air circulation.

8) Never install the inverter in living areas. The inverter will generate noise during operation, affecting daily life.

3.3 Installation Clearance Requirements

1）Reserve enough clearance around the inverter to ensure sufficient space for heat dissipation，shown as FIG 3-3.

( Under the premise of ensuring installability, the gap between the left and right sides of the inverter can be reduced

to 200mm, and it is recommended to be ≥ 500mm.)

2) In case of multiple inverters, reserve specific clearance between the inverters. 3-4

3.4.2 Steel Frame Installation

Mounting Steps:

Step 1: Level the assembled mounting-bracket by using a level, and mark the positions for drilling holes on the steel frame.

Drill the holes by using a hammer drill. Recommended aperture:10mm.

Step 2: Secure the mounting-bracket with M8 bolts and nuts.

3.4.3 Wall-Mounted Installation

M8 or M10 expansion bolts can be used to fix the wall bracket on the wall. (Note: No expansion bolt is supplied)

Mounting Steps

Step 1: Level the assembled mounting-bracket by using a level, and mark the positions for drilling holes on the installation

site.

Step 2: Insert the expansion bolts into the holes and secure them with arubber hammer. Fasten the nut with a wrench to

expand the bolt. Remove the nut, spring washer, and flat washer, and store them properly.

Step 3: Fix the mounting-bracket with the expansion bolts.

3.5 Inverter Installation

Step 1: Take out the inverter from the packing carton.

Step 2: If the inverter is installed in a high position, hoisting the inverter is recommended (refer to manual "4.3.2 Hoisting

Transport"). If not, skip performing this step.

Step 3: Hang the inverter to the mounting-bracket and ensure that the mounting ears perfectly engage with the mounting-

bracket.

Step 4: Fix the inverter with screws M6x30 (Note: It is not locked or fixed here, and the screw can be locked to the end).

4.2 Connecting the PE Cable

WARNING

Since the inverter is a transformerless inverter, neither the negative pole nor the positive pole of the

PV string can be grounded. Otherwise, the inverter will not operate normally.

Connect the additional grounding terminal to the protective grounding point before AC cable

connection, PV cable connection, and communication cable connection.

The ground connection of this additional grounding terminal cannot replace the connection of the PE

terminal of the AC cable. Make sure thoes terminals are both grounded reliably.

4.2.1 Additional Grounding Requirements

All non-current carrying metal parts and device enclosures in the PV power system should be grounded, for example, brackets

of PV modules and inverter enclosure. When there is only one inverter in the PV system, connect the additional grounding

cable to a nearby grounding point.

When there are multiple inverters in the PV system, connect grounding points of all inverters and the PV array frames to the

equipotential cable (according to the onsite conditions) to implement an equipotential connection.

4.2.2 Connection Procedure

Step 1 Prepare an external ground cable according to the following figure: strip the cable - > crimp the terminal - > cover the

heat shrinkable sleeve. Recommended terminal type: DT/OT.

Step 2 Remove the screw on the grounding terminal and fasten the cable with awrench.

Step 3 Apply paint to the grounding terminal to ensure corrosion resistance.

Communication Cable Connection

This series of models provides standard wireless communication function and optional wired communication function.

4.3.1 Data Logger Connection

Connect the Data Logger to the communication accessory port.

After successful connection, information such as power generation and running state of the inverter can be viewed via the APP

on the phone.

4.4 AC Cable Connection

4.4.1 AC Side Requirements

Before connecting the inverter to the grid, ensure the grid voltage and frequency comply with requirements, for which, refer to

Specification. Otherwise, contact the electric power company for help.

Connect the inverter to the grid only after getting an approval from the local electric power company.

4.4.2 Connection Procedure

Step 1: Disconnect the AC-side circuit breaker and prevent it from inadvertent reconnection.

Step 2: Open the wiring compartment, loosen the swivel nut of the AC waterproof connector, take out the multi-layer sealing

ring and select aseal rings according to the cable outer diameter. Lead the cable through the swivel nut, seal rings, and w

wiring compartment successively.

Step 3: Strip the protection layer and insulation layer by specific length, as described in the figure below.

≤80-140mm

FIG 4-4 Strip the protection layer and insulation layer

Step 4: Make the cable and crimp OT/DT terminal.

FIG 4-5 Make the cable

Step 5: Remove the protective box by pushing the clasp in the left and right directions. Take out the inter-pole insulation

shield of the terminal block delivered with the machine and install it on the terminal block.
