Installation Guide

Unpack and verify all components. Choose a dry, well-ventilated location.

Mount the inverter: Use provided brackets to secure on a stable surface.
Connect battery: Attach cables to battery terminals (positive to positive, negative to negative).
Connect solar panels: Use MC4 connectors to solar input terminals.
Connect AC loads: Plug devices into AC output sockets.
Ground the system: Connect grounding wire to grounding terminal.

WARNING! Ensure all connections are tight and correct polarity is observed to prevent damage.

First-Time Setup

Power on the inverter; follow initialization sequence.

Check battery voltage: Ensure battery is within 10.5V to 15V range.
Set system parameters: Use buttons to configure battery type, charging current, and output voltage.
Enable solar charging: Connect solar panels and verify charging indication on LCD.
Test AC output: Connect a small load to verify proper operation.
Configure preferences: Set low voltage cutoff, alarm thresholds, and eco mode.

CAUTION! Do not connect AC input while battery is connected. Follow sequence precisely.

Turn off all power sources before making connections.
Connect battery first, then solar panels, then AC loads.
Use appropriate cable gauges (minimum 10 AWG for battery).
Verify polarity before powering on.

Tip: Install fuse (20A recommended) between battery and inverter for added protection.

Operation Modes

Supports multiple operation modes for optimal efficiency.

Solar Priority Mode: Uses solar power first, battery as backup.
Battery Mode: Operates solely from battery power.
Grid Mode: (If equipped) Uses grid power when available.
Eco Mode: Reduces standby power consumption.
Charging Mode: Charges battery from solar or grid.
Load Management: Automatically adjusts output based on load demand.

WARNING! Do not exceed rated power capacity. Monitor battery voltage regularly.

Safety Features
