5. Setup and Installation

Follow these steps for proper installation of your EAPRO Solar PCU 1500.

1. Mounting: Choose a dry, well-ventilated area away from direct sunlight, heat sources, and flammable materials. Ensure sufficient clearance around the unit for airflow.
2. Battery Connection:
   • Ensure the inverter is OFF.
   • Connect the positive (+) terminal of the 12V battery to the BATT. (+) terminal on the inverter using the red battery connecting wire.
   • Connect the negative (-) terminal of the 12V battery to the BATT. (-) terminal on the inverter using the black battery connecting wire.
   • Ensure connections are tight and secure.
3. Solar Panel Connection:
   • Connect your solar panels (up to 1000W total) to the SOLAR input terminals (+/-).
   • Ensure the total Voc (Open Circuit Voltage) of your solar array does not exceed 22V and Vmp (Maximum Power Voltage) is around 17V for optimal charging.
   • Observe correct polarity: positive to positive, negative to negative.
4. AC Mains Input Connection: Connect the MAINS input socket on the inverter to a reliable utility grid power outlet using an appropriate power cord (not included).
5. AC Output Connection: Plug your desired appliances into the AC Output Socket on the rear panel. Ensure the total load does not exceed 850 Watts.

Important: Always double-check all connections for correct polarity and tightness before powering on the unit.

6. Operating Instructions

This section details how to operate your EAPRO Solar PCU 1500.

6.1 Powering On/Off

• To Power On: Press and hold the ON/OFF button for a few seconds until the LCD display illuminates.
• To Power Off: Press and hold the ON/OFF button for a few seconds until the display turns off.

6.2 LCD Display

The LCD display provides critical information about the inverter's status:

• Battery Voltage: Current battery charge level.
• Load Level: Indicates the percentage of connected load.
• Input Source: Shows whether the inverter is running on Mains, Battery, or Solar power.
• Error Codes: Displays specific codes in case of a fault.
• Operating Mode: Indicates the currently selected mode (e.g., UPS, Power Saving).

6.3 Operating Modes

• UPS Mode: Provides uninterrupted power supply. When mains power is available, it charges the battery and powers the load. Upon mains failure, it seamlessly switches to battery power.
• Power Saving Mode: Optimizes energy consumption by reducing standby power. The inverter may enter a low-power state when no load or very light load is detected.
• Real Time Clock Based Operation: The inverter can be configured for specific charging and discharging cycles based on a real-time clock, optimizing solar energy usage and battery life. Refer to the advanced settings menu on the LCD for configuration.

Use the MODE (UPS) and HIGH/LOW buttons to navigate through menus and select desired operating modes or settings.

7. Maintenance

Regular maintenance ensures the longevity and optimal performance of your EAPRO Solar PCU 1500.

• Cleaning: Periodically clean the exterior of the inverter with a soft, dry cloth. Ensure ventilation openings are free from dust and debris. Do not use liquid cleaners.
• Connections: Annually check all electrical connections (battery, solar, mains, output) for tightness and corrosion. Loose connections can cause overheating and poor performance.
• Battery Health: Monitor battery health regularly, especially if using lead-acid batteries. Ensure battery terminals are clean and free of corrosion.
• Environment: Ensure the installation environment remains dry, cool, and well-ventilated.
