1. Product Overview
The EDECOA 3000W 24V Hybrid Solar Inverter is an integrated power solution designed for off-grid solar systems. It combines the functions of a power inverter, an 80A MPPT solar charger, and a battery charger into a single unit. This pure sine wave inverter converts 24V DC battery power to 230V AC, suitable for various household and industrial applications.
Key features include an LCD display for battery type settings (compatible with FLD, AGM, Gel, and LiFePo4 batteries), multiple charging and output modes, and comprehensive safety protections.

2. Safety Instructions
Please read all instructions and warnings carefully before installation and operation. Failure to follow these instructions may result in electric shock, fire, or severe injury.
- Installation must be performed by qualified personnel.
- Ensure all wiring is correctly sized and properly insulated.
- Do not disassemble the inverter. There are no user-serviceable parts inside.
- Keep the inverter away from flammable materials, moisture, and direct sunlight.
- Ensure adequate ventilation around the unit to prevent overheating.
- Always disconnect power sources (solar, battery, AC grid) before performing any maintenance or wiring.
- This inverter is designed for off-grid use only. Do not connect its AC output directly to the public grid.

4. Installation and Setup
4.1 Mounting the Inverter
Mount the inverter vertically on a solid surface in a well-ventilated area. Ensure sufficient clearance around the unit for heat dissipation. Refer to the dimensions for proper placement.
Figure 3: Product dimensions for installation planning.
4.2 Wiring Connections
Follow these steps for wiring. Always ensure all power sources are disconnected before making connections.
- Battery Connection: Connect the 24V battery bank to the inverter's battery terminals. Ensure correct polarity (positive to positive, negative to negative). The inverter is compatible with FLD, AGM, Gel, and LiFePo4 battery types.
- Solar Panel Connection: Connect your solar panel array to the PV input terminals. The inverter supports up to 3000W PV input with an MPPT voltage range of 55-430Vdc.
- AC Load Connection: Connect your AC loads (appliances) to the AC output terminal. The inverter provides a 230V AC pure sine wave output.
- AC Input (Optional): If using grid or generator power for charging, connect the AC input to the designated terminal.

5. Operating Instructions
5.1 Initial Power-Up
After all connections are secure, switch on the battery breaker, then the solar array breaker (if applicable), and finally the inverter's power switch. The LCD display will illuminate, showing system status.
5.2 LCD Display and Settings
The digital display provides real-time information on voltage, current, power, and operating modes. Use the control buttons to navigate menus and adjust settings such as battery type, charging priorities, and output modes.
5.3 Charging Modes
The inverter offers four optional charging modes:
- CSO (Solar First): Solar energy charges the battery as the primary priority. The utility (grid) charges the battery only when solar energy is unavailable.
- SNU (Solar and Utility): Both solar energy and utility power charge the battery simultaneously.
- OSO (Solar Only): Solar energy is the sole charging source, regardless of grid availability.
- Utility Only: The utility (grid) is the sole charging source.
Figure 6: Overview of the three primary battery charging modes.
5.4 Output Modes
The inverter features two load output modes:
- SUB (Solar-Utility-Battery): Solar energy powers loads as the primary priority. If solar is insufficient, the utility grid provides power. If both are unavailable, the battery supplies power.
- SBU (Solar-Battery-Utility): Solar energy powers loads first. If solar is insufficient, the battery supplies power. The utility grid provides power only when the battery voltage drops to a low level.
Figure 7: Explanation of the two load output priority modes.
5.5 ECO Mode
The ECO mode (<15W) minimizes power consumption when the inverter is idle or under light load, preventing unnecessary battery drain.
5.6 Monitoring Software
The inverter supports monitoring via a dedicated software interface, allowing users to view real-time system data and adjust settings from a computer or mobile device (Wi-Fi module sold separately).
Figure 8: Example of the monitoring software interface.
6. Maintenance
Regular maintenance ensures optimal performance and longevity of your inverter.
- Cleaning: Periodically clean the exterior of the inverter with a dry cloth. Ensure ventilation openings are free from dust and debris.
- Connections: Annually check all electrical connections for tightness and signs of corrosion.
- Battery Health: Monitor battery voltage and performance regularly. Follow battery manufacturer guidelines for maintenance.
- Environment: Ensure the installation environment remains within specified temperature and humidity ranges.
7. Troubleshooting
If the inverter is not operating correctly, refer to the following common issues before contacting support.
| Problem | Possible Cause | Solution |
|---|---|---|
| No output power | Inverter off, low battery voltage, overload, short circuit | Check power switch, charge batteries, reduce load, check for short circuits. |
| Battery not charging | Solar panels disconnected, incorrect charging mode, faulty battery | Check solar connections, verify charging mode settings, test battery. |
| Overload warning | Connected load exceeds inverter capacity | Reduce the total power of connected appliances. |
| Overheating warning | Insufficient ventilation, blocked vents, high ambient temperature | Ensure clear airflow, clean vents, move to a cooler location. |
