Anern 4200W Hybrid Inverter 24V User Manual

1. Introduction

This manual provides essential information for the safe and efficient operation of your Anern 4200W Hybrid Inverter 24V. This off-grid inverter integrates the functions of an inverter and a charger, featuring an integrated 120A MPPT photovoltaic charge controller. It delivers a pure sine wave AC output at 220V/230V. A 24V battery connection is required for operation. This inverter does not support split-phase or three-phase systems.

2. Safety Information

Important Safety Instructions: Read all instructions carefully before installation and operation.

• The starting power for inductive loads must be at least three times the inverter's rated power. Exceeding this limit can damage the inverter.
• Ensure all circuits are connected correctly according to the wiring diagrams and that a dedicated switch is installed for each circuit.
• Follow the correct startup sequence: first, connect the battery, then start the inverter, and finally, activate the PV, grid, and load switches. For shutdown, reverse this sequence.
• Always ensure proper grounding for all components, especially solar panels, to prevent electrical interference and ensure safety.

• PV Input: Max 8200W, Open Circuit Voltage 500VDC, MPPT Voltage Range 90-450VDC, Start-up Voltage 120VDC. Recommended PV Cable: 10AWG / 6mm². Connect solar modules in series.
• AC Input: 230VDC, Max AC Input Voltage 300VAC, Max AC Charge Current 160A. Recommended AC Cable: 10AWG / 6mm². Recommended Breaker: 63A.
• AC Output: 4200W, 220V/230V. Recommended AC Cable: 10AWG / 6mm². Recommended Breaker: 63A. Note: The inverter's output is 230V. A converter (not included) may be needed for 110V appliances.

6. Operating Instructions

The inverter offers various operating modes to optimize energy usage based on your preferences and available power sources.

6.1 Charge Modes

You can configure the battery charge current via the LCD display settings. The following charge modes are available:

• Solar Priority (CSO): Solar energy charges the battery first. Utility power charges the battery only when solar energy is unavailable.
• Solar Only (OSO): Solar energy is the sole charging source, regardless of utility availability.
• Utility Priority (SNU): Utility power and solar energy charge the battery simultaneously.
• Solar and Utility Hybrid: (Default) Solar and utility power charge the battery simultaneously.

6.2 Output Modes

The inverter supports different output priorities:

• Utility Priority (USB): Loads are primarily powered by the public grid. Solar and battery power are used only if the grid is unavailable.
• Solar Priority (SUB): Loads are primarily powered by solar energy. If solar energy is insufficient, the grid supplies power. The battery powers loads only when both solar and grid are unavailable.
• SBU Priority (Default): Loads are primarily powered by solar energy. If solar energy is insufficient, the battery supplies power. The grid is used only when both solar and battery power are insufficient or the battery voltage drops below a set warning level.
