1. Introduction
This ECGSOLAX Hybrid Solar Inverter is a multi-function inverter/charger designed to provide uninterruptible power support. It integrates the functions of an inverter, a solar charger, and a battery charger into a portable unit. The comprehensive LCD display and user-friendly buttons allow for easy configuration of settings such as battery charging current, AC/solar charger priority, and acceptable input voltage, adapting to various application needs.
The solar charging module incorporates the latest optimized MPPT (Maximum Power Point Tracking) technology. This ensures quick and efficient tracking of the maximum power point of the PV array in any environment, maximizing the energy harvested from the solar panels in real-time. The inverter then converts this DC power into a pure sine wave AC output.

5. Installation and Setup
5.1. Safety Information
WARNING: All wiring must be performed by a qualified personnel to ensure system safety and efficient operation. Failure to do so may result in serious injury or damage to the equipment.
CAUTION: For safety operation and regulation compliance, it is requested to install a separate DC over-current protector or disconnect device between the battery and the inverter. It may not be requested to have a disconnect device in some applications, however, it is still requested to have over-current protection installed.

5.3. Battery Connection
WARNING: It is very important for system safety and efficient operation to use appropriate cable for battery connection. To reduce risk of injury, please use the proper recommended cable as below.
Figure 5.3: Battery Wiring Diagram for 4.2KW (2x12V) and 6.2KW (4x12V) Inverters, with Recommended Cable Sizes.
| Model | Wire Size | Cable (mm²) | Torque value (max) |
|---|---|---|---|
| 4.2KW/6.2KW | 1 x 2AWG | 25 | 2 Nm |
5.4. AC Input/Output Connection
CAUTION: Before connecting to AC input power source, please install a separate AC breaker between the inverter and AC input power source. This will ensure the inverter can be securely disconnected during maintenance and fully protected from over current of AC input. The recommended spec of AC breaker is 32A for 4.2KW and 50A for 6.2KW.
CAUTION: There are two terminal blocks with "IN" and "OUT" markings. Please do NOT mis-connect input and output connectors.
WARNING: All wiring must be performed by a qualified personnel. It is very important for system safety and efficient operation to use appropriate cable for AC input connection. To reduce risk of injury, please use the proper recommended cable size as below.

6. Operating Instructions
6.1. LCD Display and Button Operation
The inverter features a comprehensive LCD display and intuitive function buttons (refer to Figure 3.1 in Product Overview) for user-configurable settings. These allow you to monitor system status, adjust charging parameters, and set power priorities.
6.2. Output Source Priority Configuration
The inverter allows you to configure the load power source priority based on your energy management needs. This setting determines which power source (Utility, Solar, or Battery) is used first to supply power to your connected loads.
Figure 6.2: Output Source Priority Settings (Program 01).
| Setting | Mode | Description |
|---|---|---|
| 01 | USB (Utility first) | Utility will provide power to the loads as first priority. Solar and battery energy will provide power to the loads only when utility power is not available. |
| 01 | SUB (Solar first - default) | Solar energy provides power to the loads as first priority. If solar energy is not sufficient to power all connected loads, utility will supply power to the loads at the same time. Battery provides power to the loads only when any one condition happens: - Solar energy and utility is not available. - Solar energy is not sufficient and utility is not available. |
| 01 | SBU (SBU priority) | Solar energy provides power to the loads as first priority. If solar energy is not sufficient to power all connected loads, battery energy will supply power to the loads at the same time. Utility provides power to the loads only when battery voltage drops to either low-level warning voltage or the setting point in program 12. |
7. Maintenance
- Regularly inspect all wiring and connections for any signs of damage, corrosion, or loose contacts. Ensure all terminals are securely tightened.
- Keep the inverter's ventilation openings clear of dust and debris to ensure proper airflow and prevent overheating. Use a soft, dry cloth to clean the exterior.
- Monitor the LCD display for any fault indicators or warning messages. Refer to the troubleshooting section for guidance on resolving common issues.
- Periodically check the battery bank for proper voltage, electrolyte levels (if applicable), and overall health. Follow battery manufacturer guidelines for maintenance.
- Ensure the environment around the inverter is within the specified operating temperature range (-10°C to 55°C) and free from excessive humidity.
8. Troubleshooting
- No Power Output: Check the AC input breaker, battery connections, and inverter's power switch. Ensure the battery voltage is within the operational range.
- Fault Indicator On: Note the specific fault code displayed on the LCD. Refer to the detailed manual (if available) or contact technical support with the fault code for diagnosis.
- Battery Not Charging: Verify solar panel connections and output. Check AC input if AC charging is enabled. Ensure charging current settings are appropriate.
- Inverter Overheating: Ensure adequate ventilation around the unit. Clear any obstructions from the cooling fans. Reduce load if continuously operating at maximum capacity.
- Unstable Output Voltage: Check input voltage stability from both solar and utility sources. Ensure all connections are secure.
