Quick Installation Guide

Important Information

The contents of this document are subject to periodic updates. This guide is intended to supplement, not replace, the user manual and product safety instructions. Always read the user manual and relevant standards before operation. Professional personnel trained in electrical systems and safety regulations should perform all operations.

Before installation, verify that all components are present and undamaged. Contact the shipping company or Sungrow immediately in case of damage or missing items. Ensure cables are intact and well-insulated, using appropriate tools and personal protective equipment.

Safety Statement

⚡ DANGER

High voltages are present during operation, posing a risk of electrical shock, severe injury, or death. Non-professional personnel must not disassemble the components.

⚠️ CAUTION

Keep the charger away from flammable and explosive substances. Store in a dry, clean, well-ventilated area, free from harmful gases. Avoid storing near corrosive objects.

ℹ️ NOTICE

• During transport, the charger must be securely packed, marked with the loading direction, and not stored upside down.
• Secure the equipment to prevent violent shaking and damage during transport.
• Upon arrival, inspect for transport damage and contact the shipping company if necessary.
• Verify that all delivered devices match the delivery list.

• Adjustable spanner [Image: Adjustable wrench]

Mounting Place Requirements

Ensure the installation location meets the following conditions:

• Ambient temperature: -30°C to 50°C
• Relative humidity: ≤ 95%
• Sufficient cooling space around the unit.
• Avoid direct sunlight and flammable/explosive environments.

Dimensions and Weight

Cable Connection

Note: Cable connection must be performed before charger installation. Recommended cable cross-section: 2.5mm².

1. Remove the back cover of the charger. [Illustration: Screwdriver removing charger back cover]
2. Thread the power cable through the designated opening. [Illustration: Cable being fed into the charger housing]
3. Crimp the terminals onto the cable wires. Use appropriate torque: M3 terminals at 0.5±0.1 N·m, M5 terminals at 3±0.2 N·m. [Illustration: Crimping tool attaching terminals to wires, with torque specifications]
4. Connect the prepared cable wires to the corresponding terminals inside the charger. [Illustration: Wires connected to internal terminals]
5. Install the back cover securely. [Illustration: Back cover being reattached]

Wall-mounted Charger Installation

Preparation: Before drilling, check for hidden water or electrical wiring in the wall. Use a 6mm drill bit with a drilling depth of approximately 45mm. The wall mounting surface must support at least 4.5 times the charger's weight.

1. Install the backplate onto the wall using tapping screws. [Illustration: Backplate being screwed to a wall]
2. Install the socket-out. It is recommended to place it approximately 20cm to the right and below the charger. Site conditions may dictate the final placement. [Illustration: Socket-out mounted on the wall]
3. Mount the charger onto the installed backplate using M4 screws, applying a torque of 1.2±0.1 N·m. [Illustration: Charger being attached to the backplate]

Pile-mounted Charger Installation (Optional)

Preparation: Use a 12mm drill bit with a drilling depth of approximately 85mm for pole mounting.

1. Perform AC line installation on the pile. [Illustration: AC line connection on a pole]
2. Install the charger components onto the pile after threading. [Illustration: Components being attached to a pole]
3. Install the backplate and the socket-out onto the pile using M4 screws (torque 1.2±0.1 N·m). [Illustration: Backplate and socket-out mounted on a pole]
4. Install the upper and lower hanging plates, then attach the charger to these plates. [Illustration: Charger mounted using hanging plates on a pole]

Inspection Before Commissioning

Commissioning

1. Confirm that all inspected items meet the requirements before commissioning.
2. Close the cable inlet leakage protection circuit breaker.
3. Power on the charger. Allow approximately one minute for the power-on self-test.
4. After the self-test, observe the status of the indicators.
