Anern Hybrid Solar Inverter Instruction Manual

1. Introduction and Overview

This manual provides detailed instructions for the installation, operation, and maintenance of your Anern Hybrid Solar Inverter. The Anern Hybrid Solar Inverter is a pure sine wave inverter designed for off-grid solar systems, capable of running with or without a battery (note: low power inverters of 3.2KW and below require battery connection for use). It features a built-in MPPT solar charge controller and offers multiple charging and output modes to suit various application requirements.

The AN-SCI-MAX series includes models up to 10.2KW, while the AN-SCI-ECO series covers models up to 6.2KW. Both series are designed for efficiency and reliability in managing solar power.

2. Safety Information

WARNING: This is an off-grid inverter. Please read all safety instructions carefully before installation and operation.

• Low power inverters (3.2KW and below) must be connected to batteries for proper operation.
• The starting power of inductive loads should be at least three times the inverter's rated power to prevent damage.
• Ensure all circuits are connected correctly and install appropriate circuit breakers for each circuit.
• Always follow the correct power-on and power-off sequence.

Power On Order:

1. First, turn on the battery.
2. Start the inverter.
3. Then, turn on the circuit breakers for photovoltaic (PV), mains, and load.

Power Off Order (Reverse of Power On):

1. First, turn off the circuit breakers for load, mains, and photovoltaic (PV).
2. Turn off the inverter.
3. Finally, turn off the battery.

3. Product Features

The Anern Hybrid Solar Inverter offers a range of advanced features for efficient solar power management:

• Pure Sine Wave Output: Provides high-quality and stable AC current, compatible with most loads, protecting electrical devices and extending their service life.
• Battery-Free Operation: Capable of running without a battery (for models above 3.2KW). For battery-free operation, the solar module voltage must exceed 360V DC.
• One-Key Factory Reset: Convenient function for restoring default settings.
• PV Automatic Lithium Battery Activation: Solar input can automatically activate lithium batteries.
• Integrated MPPT Solar Controller:
• 160A MPPT solar controller for 10.2KW models.
• 120A MPPT solar controller for AN-SCI-ECO series.
• High Solar Input Power: Max 7500W (for 4.2KW) & 10800W (for 6.2KW) solar charge.
• Wide PV Input Voltage Range: 90-450VDC for AN-SCI-MAX, 60-450VDC for AN-SCI-ECO.
• Anti-Dust Kit: Built-in for enhanced durability in harsh environments.
• Smart Battery Charge Design: Optimizes battery lifespan.
• Dual PV Input & AC Output (10.2KW models):
• Two independent MPPTs for convenient solar panel wiring and reduced need for sink boxes.
• Dual AC output with primary and secondary circuits. If PV and mains are absent and battery voltage is low, the primary circuit shuts down, and only the secondary output is maintained (Super Power Saving mode).
• WIFI Monitoring: Available for iOS and Android systems, allowing remote system control and monitoring.
• Compatible Battery Types: Supports Lead-acid, Lithium iron phosphate (LiFePO4), Gel, AGM, FLD, SLD, and user-defined battery types.
• Touch Button & LED Display: User-friendly interface for monitoring and control.
