Product Overview

This unit is designed to be wall-mounted. Please ensure the installation is perpendicular to the floor and the AC plug at the bottom. Do not install the device on a slanting wall.

To mount the inverter on the wall, please follow the procedure below:

1. Screw the mounting bracket on the wall with 8 M6 Phillips head screws. Please refer to Figure 3-3.

2. Attach the inverter to the mounting bracket.

3. Use Hex Wrench fixing the inverter with 2 M4 Hexagon Socket screws. Please refer to Figure 3-4.

3 Installation

- The unit should not be installed in a direct sunlight.

- Servicing of batteries should be performed or supervised by personnel knowledgeable about batteries and the required precautions.

CAUTION !

WARNING !

- Do not install the unit near or on flammable surfaces.

- Please mount the unit tightly on a solid / smooth surface.

Figure 3-5 : Proper installation gaps

- The bracket supplied with the unit is specially designed and should be the only mounting device used for the unit.

- It is recommended to install the inverter in a suitable location which offers non-obscured and safe access, in turn ensuring easy access for service and maintenance.

- Please install hybrid inverter at an eye level to allow easy observation for operation and parameter setting.

- Ambient temperature -25° C~60° C. (power de-rating above 40° C)

CAUTION !

Installation

• Please use PVC insulated outdoor power cables and connected to the inverter through a specific certified connector.

• Please use ungrounded PV power system due to E5 does not have galvanic isolation between the DC-input, Battery and AC-output.

• E5 has array insulation resistance measuring function. Please ensure the insulation resistance of array is over 550k ohm.

• There are two earth bonding methods for E5. You can ground the inverter by enclosure grounding hole that shown in Figure 2-4

or by PE terminal of AC plug. Please use at least one grounding method to avoid electric shock.

• Inverter can support DC inputs in parallel connection (1 MPP tracker) or

separate connection (2 MPP trackers).

• The overview of wiring please refers to Figure 4-1.

4　Wiring

4.1 Preparation Before Wiring

WARNING：SHOCK HAZARD!

- Whenever a PV array is exposed to sunlight, a shock hazard may exist due to output wires or exposed terminals. To reduce the risk of shock during installation, cover the array with an opaque (dark) material and ensure that the AC/DC disconnect switch in the inverter is set to OFF before commencing any wiring.
