• Battery Safety: Work with batteries requires caution. Wear appropriate personal protective equipment (PPE) including eye protection and gloves. Do not short-circuit battery terminals.
• Disconnection: Before performing any maintenance or wiring, ensure all power sources (PV array, AC input, battery) are disconnected.
• Off-Grid Use: This inverter is designed for off-grid systems only. Do not connect its AC output directly to the public utility grid.

3. Installation and Setup

3.1 Package Contents

Verify that all items are present in the package:

• EDECOA 6200W 7000VA Solar Power Inverter
• At least one MPPT charge controller (80A or 110A) - Note: The 110A MPPT controller is integrated into this model.
• User Manual (this document)
• Communication Cable (RS232)

3.2 Physical Installation

Choose a suitable mounting location that is dry, well-ventilated, and protected from direct sunlight and moisture. Ensure there is sufficient clearance around the inverter for proper airflow.

• Mount the inverter vertically on a sturdy wall or surface using appropriate fasteners.
• Ensure the mounting surface can support the weight of the inverter (approximately 7.8 kg).

3.3 Wiring Connections

Refer to the diagram below for connection points. All wiring must comply with local electrical codes and regulations.

Figure 3: Overview of the inverter's display, buttons, and connection ports including battery input, PV input, AC output, AC input, and ground terminal.

1. Grounding: Connect the ground terminal of the inverter to a reliable earth ground.
2. Battery Connection: Connect the 48V DC battery bank to the "Batt. In (+)" and "Batt. In (-)" terminals. Ensure correct polarity. This inverter is compatible with FLD, AGM, Gel, and LiFePo4 battery types.
3. PV Array Connection: Connect the solar PV array to the "PV In+" and "PV In-" terminals. Ensure the PV array voltage is within the 55-450Vdc MPPT range and the maximum PV input VOC does not exceed 450V DC.
4. AC Output Connection: Connect your AC loads to the "AC Out Port".
5. AC Input Connection (Optional): If using a grid or generator as a backup, connect it to the "AC In Port".

Important: Always connect the battery first, then the PV array, and finally the AC input/output. Disconnect in reverse order.

4. Operating Instructions

4.1 Initial Power-Up

• After all connections are secure, switch on the battery breaker.
• Turn on the ON/OFF switch on the inverter.
• The LCD display will illuminate, showing the system status.
• If applicable, turn on the PV array breaker and then the AC input breaker.

4.2 LCD Display and Buttons

The LCD provides real-time information about the inverter's operation, including input/output voltages, charging current, battery status, and load percentage. Use the touchable buttons (ESC, UP, DOWN, ENTER) to navigate through menus and adjust settings.

Figure 5: The LCD display provides comprehensive system information, including input/output parameters, battery status, and charging details.

4.3 Operating Modes

The inverter supports various operating modes to optimize power usage:

• Utility Priority Mode: AC input (grid/generator) is the primary power source. Solar and battery are used as backup.
• Solar Priority Mode: Solar power is the primary source. Battery is used when solar is insufficient, and AC input is used as a last resort.
• Battery Priority Mode: Battery power is the primary source. Solar charges the battery, and AC input is used only when the battery is low.
• ECO Mode: Reduces standby power consumption to less than 15W, extending battery life.

Figure 6: The inverter offers a default smart mode and three priority options for charging, allowing users to select the best configuration for their power needs.

4.4 Battery Charging

The integrated 110A MPPT solar charger and 80A AC charger ensure efficient battery charging. The inverter supports 6-stage charging for optimal battery health and lifespan:

• Soft Start: Gentle initial charge.
• Bulk: Main charging stage, delivering maximum current.
• Absorption: Constant voltage charge to fully charge the battery.
• Float: Maintains battery at full charge.
• Equalize: Periodically balances battery cells (for certain battery types).
• Float (Re-float): Maintains charge after equalization.

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your EDECOA inverter.

• Cleaning: Periodically clean the exterior of the inverter with a dry, soft cloth. Do not use liquid cleaners or solvents.
• Ventilation: Ensure ventilation openings are free from dust and debris. Clean them gently with a brush or compressed air if necessary.
• Connections: Annually check all electrical connections for tightness. Loose connections can cause overheating and damage.
• Battery Inspection: Regularly inspect battery terminals for corrosion and clean them if necessary. Monitor battery voltage and health according to battery manufacturer guidelines.
• Environmental Check: Ensure the installation environment remains within specified temperature and humidity ranges.

For any internal maintenance or repairs, contact qualified service personnel. Do not attempt to open the inverter casing yourself, as it contains high voltage components.
