Installation Guide for Solplanet ASW 3000/3680/4000/5000-S Solar Inverter

Quick guide from the manual

This document provides essential installation and commissioning steps for the Solplanet ASW 3000/3680/4000/5000-S series solar inverters. Only qualified technicians should perform installation. Ensure all DC switches and AC circuit breakers are disconnected before starting any electrical work. The inverter must be grounded firmly to prevent electrical shock.

Mounting

The inverter should be installed out of reach of children in an environment with an ambient temperature below 40°C. Avoid direct sunlight, rain, or snow; a protective roof is recommended. The unit is suitable for solid vertical walls or tilted backwards by a maximum of 15°. Do not install on plasterboard or similar materials.

• Drill 3 holes with a 10mm bit to a depth of 70mm using the wall mounting bracket as a template.
• Insert wall plugs and fix the bracket using self-tapping screws (SW10).
• Hang the inverter onto the bracket.
• Secure the inverter on both sides using M4 screws (torque: 1.6Nm).

AC connection

All electrical installations must comply with local and national rules. The AC cable must be prepared with a ferrule according to DIN 46228-4.

• Loosen the swivel nut of the AC connector.
• Insert the crimped conductors into the corresponding terminals.
• Tighten the screws using the provided Allen key (torque: 2.0Nm).
• Plug the AC connector into the socket on the inverter.
• Ensure the PE conductor is 2mm longer than the L and N conductors.

DC connection

Before connecting, ensure PV modules have good insulation against the ground. The open-circuit voltage of the PV modules must not exceed the maximum input voltage of the inverter on the coldest day.

• Check the polarity of DC cables.
• Ensure the DC switch is disconnected.
• Insert the DC plug connectors with sealing plugs into the inverter's DC input connectors to ensure the required protection degree.
• Do not disconnect DC connectors under load.

Communication setup

Communication cables must be CAT-5E or higher-level shielded cables. Keep them separate from power cables to avoid interference.

• RS485: Loosen the swivel nut on the communication cover, remove sealing plugs, and route the cable through the magnetic ring and cover. Connect to the socket and tighten the swivel nut (torque: 1.6Nm).
• Smart Meter: Remove the communication plate, route the cable through the gland, press the latch of the smart meter terminal to insert the cable, and reattach the plate.

Commissioning

Before starting, verify that the inverter is grounded, ventilation is adequate, and grid voltage is within the permitted range. Ensure all sealing plugs are tight.

1. Switch on the AC circuit breaker between the inverter and the grid.
2. Switch on the DC switch.
3. The inverter will start automatically when sufficient DC power is applied and grid conditions are met.

Technical data

The series supports a maximum DC input voltage of 580V and an MPP voltage range of 80-550V. The operating temperature range is -25°C to +60°C. The unit features IP65 protection and convection cooling.
