At Zhejiang SUNOHOO Technology Co., Ltd, we take pride in developing intelligent and efficient renewable energy solutions designed to empower users with energy independence and stability. Our Hybrid Solar Inverter (Off-Grid) is the cornerstone of a reliable solar power system, combining advanced power conversion technology, intelligent control systems, and flexible energy management for both residential and commercial applications.

1. Product Overview

The Hybrid Solar Inverter Off-Grid is an integrated energy management device that efficiently converts solar energy into usable AC power while managing energy flow between solar panels, batteries, and electrical loads. Designed for off-grid and backup power systems, it enables continuous power supply even in areas with unstable or no grid connection.

This inverter not only supports solar charging, but also battery storage and generator input, offering a true hybrid experience. Whether you’re powering a remote cabin, a rural home, or an industrial facility, our inverter ensures 24/7 energy availability with seamless automatic transitions between sources.

2. Product Functions and Uses

Our Hybrid Solar Inverter is designed for multi-source energy integration and autonomous operation.

Its primary functions include:

• DC to AC Conversion: Converts direct current (DC) from solar panels or batteries into alternating current (AC) for home and business appliances.
• Battery Charging & Management: Supports smart battery charging from both solar and generator inputs, optimizing charge cycles and extending battery life.
• Load Management: Automatically prioritizes solar power usage and efficiently manages battery backup for critical loads.
• Generator Compatibility: Works seamlessly with diesel or petrol generators to ensure uninterrupted power supply during extended cloudy days.
• Monitoring & Control: Equipped with an LCD display and remote monitoring capability for real-time data on performance, voltage, and energy output.

Typical applications include:

• Remote homes and off-grid cabins
• Agricultural irrigation systems
• Small commercial operations
• Telecommunication towers
• Backup systems for critical facilities (hospitals, schools, etc.)

5. User Manual Overview

Before Installation

• Read the manual carefully before operation.
• Ensure all components (inverter, cables, fuses, breakers) are undamaged.
• Select an installation location that is dry, well-ventilated, and away from direct sunlight or heat sources.

Operation Modes

• Solar Priority Mode: Solar power supplies load first, then charges the battery.
• Battery Priority Mode: Battery discharges to supply load when solar is insufficient.
• Generator Mode: Automatically starts the generator when battery voltage drops below threshold.

Maintenance Tips

• Clean air vents regularly.
• Check all cable connections monthly.
• Update firmware (if applicable) via USB or Wi-Fi module.

6. Installation Process

Installing the Hybrid Solar Inverter Off-Grid is straightforward and can be completed by a certified technician following these steps:

Step 1: Site Preparation

• Choose a vertical, shaded wall or rack mount.
• Maintain at least 30 cm clearance around the inverter for ventilation.

Step 2: Mounting the Inverter

• Use provided brackets or screws to secure the inverter firmly on the wall.
• Ensure it is level and stable.

Step 3: Electrical Connections

• Connect the Battery Bank: observe polarity (+/-) carefully.
• Connect the Solar Panels: via the PV input terminal (ensure correct voltage range).
• Connect the AC Output: to the load distribution panel.
• Optional: Connect generator input if hybrid backup is desired.

Step 4: System Start-Up

• Turn on the battery switch first.
• Then, power on the inverter and check the LCD screen for correct system parameters.
• Turn on the solar array breaker.
• Verify system operation (solar charging, load supply, battery status).

Step 5: Testing and Commissioning

• Confirm that voltage and frequency are within expected ranges.
• Test load operation under solar and battery mode.
• Confirm automatic switching between energy sources.
