4. Setup and Installation

Follow these steps carefully to install your power inverter system. While the video below provides a general visual guide, always refer to the specific wattage and voltage of your Temank PowMr 2500W 24V inverter and associated components.

4.1 Component Mounting

1. Mount Inverter and Controller: Securely mount the inverter and the solar charge controller on a stable, vertical surface (e.g., a wall) in a well-ventilated area. Ensure there is sufficient space around both units for airflow.
2. Install Circuit Breakers: Install appropriate DC circuit breakers. For this 24V system, you will need:
   • Two DC air circuit breakers (e.g., 63A) for the PV input to the controller and the controller's charging line to the battery.
   • One molded-case DC breaker (e.g., 250A) for the battery-to-inverter discharge line.

4.2 Wiring Connections

Important: Always ensure all power sources are disconnected before making any wiring connections. Double-check polarity (positive to positive, negative to negative) for all DC connections.

1. Controller to Battery Breaker: Connect the controller's battery port to the battery-side DC breaker. Use appropriate gauge wires (e.g., 6AWG or thicker for higher current).
2. Battery Breaker to Battery: Connect the other side of the battery-side DC breaker to your 24V battery terminals. Ensure secure connections.
3. Controller to PV Breaker: Connect the controller's PV input port to the PV input DC breaker.
4. PV Breaker to Solar Array: Connect your solar array (solar panels) to the PV input DC breaker.
5. Inverter to Battery Breaker: Connect the inverter's positive and negative DC input terminals to the 250A DC breaker. Use heavy-gauge battery cables provided or suitable alternatives.
6. AC Output Wiring: From the inverter's AC output terminals, wire out to the AC loads you intend to power. Ensure proper distinction between live, neutral, and ground wires.

4.3 Power-On Sequence

After all wiring is complete and verified for security and correct polarity:

1. Activate Controller Battery Breaker: First, switch on the DC breaker connected between the battery and the solar charge controller.
2. Activate PV Breaker: Next, switch on the DC breaker connected to the solar array (PV input).
3. Activate Inverter Breaker: Then, switch on the 250A DC breaker connected between the battery and the inverter.
4. Power On Inverter: Finally, flip the inverter's rocker switch to the "ON" position. The inverter will start operating, and connected AC loads will receive power.

Note: Always follow this sequence to prevent potential damage to the system components.

5. Operating Instructions

Once the inverter is powered on, you can monitor and control its operation using the remote control panel and the unit's display.

5.1 Remote Control Panel

The remote control panel allows convenient monitoring of key system parameters from a distance (up to 15ft away). The LCD display shows:

• Battery Input Voltage (V)
• AC Output Voltage (V)
• AC Output Power (W)
• AC Output Frequency (Hz)
• Pure Sine Waveform Indicator
• Inverter Operating Status (Normal/Error)

5.2 Connecting AC Loads

The inverter provides two standard AC outlets and an AC output terminal for hardwiring. Ensure that the total wattage of all connected appliances does not exceed the inverter's continuous power rating (2500W) to prevent overload. For appliances with high startup surge currents (e.g., motors, refrigerators), ensure their surge wattage is within the inverter's peak power rating (5000W for 10 seconds).

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your inverter. Perform the following checks periodically:

• Cleanliness: Keep the inverter's exterior and ventilation openings clean and free from dust and debris. Use a dry cloth for cleaning.
• Connections: Periodically check all electrical connections (DC input, AC output, battery, solar panels) to ensure they are tight and free from corrosion.
• Cables: Inspect cables for any signs of wear, fraying, or damage. Replace damaged cables immediately.
• Ventilation: Ensure that the cooling fans are operating correctly and that the inverter's ventilation is not obstructed.
• Battery Health: Monitor your battery's health and charge level regularly, especially in off-grid systems.
