4. Setup and Installation

Proper installation is crucial for the safe and efficient operation of the inverter charger. Refer to the wiring diagram below for a visual guide.

Figure 3: Connection Diagram illustrating the setup with solar panels, solar controller, battery, utility power/generator, and home appliances.

4.1 Battery Connection

1. Ensure the inverter is OFF and all power sources are disconnected.
2. This inverter operates with a 24V battery system. Connect two 12V batteries in series to achieve 24V.
3. Connect the positive (red) battery cable to the inverter's positive terminal and the negative (black) battery cable to the inverter's negative terminal.
4. CAUTION: Be extremely careful not to reverse the polarity, as this will cause severe damage to the inverter.
5. Secure all connections tightly.

4.2 AC Input Connection

The AC input allows the inverter to charge batteries from the grid or a generator, and to pass through AC power to loads when available. Use a 3-core AC cable (Live (L), Neutral (N), and Ground (G)).

1. Remove the protective cover of the AC input terminal block.
2. Connect the Live (L) wire to the terminal labeled 'AC Input L'.
3. Connect the Neutral (N) wire to the terminal labeled 'AC Input N'.
4. Connect the Ground (G) wire to the grounding screw.
5. Ensure all connections are secure and replace the protective cover.

4.3 AC Output Connection

The AC output is where you connect your home appliances or loads. This inverter provides 120V/240V split-phase output. Use appropriate 3-core AC cables for your loads.

1. Remove the protective cover of the AC output terminal block.
2. Connect the Live (L1) wire for 120VAC output to 'AC Output L1'.
3. Connect the Live (L2) wire for 240VAC output to 'AC Output L2'.
4. Connect the Neutral (N) wire to 'AC Output N'.
5. Connect the Ground (G) wire to the grounding screw.
6. Ensure all connections are secure and replace the protective cover.

4.4 Remote Control and Sensor Connections

• Remote Control: Connect the remote control cable to the 'Remote Control' port on the inverter.
• Battery Temperature Sensor: Connect the optional battery temperature sensor to the designated port to optimize charging based on battery temperature.
• Automatic Generator Start (AGS): Connect your generator's start/stop control wires to the AGS terminals. The inverter will automatically start the generator when battery voltage drops below a set threshold.

5. Operating Instructions

After successful installation, follow these steps to operate your inverter charger:

5.1 Initial Power-Up

1. Ensure all battery and AC connections are secure.
2. Turn on the battery breaker (if installed).
3. Switch the inverter ON using the main power switch. The LCD display will illuminate.
4. If AC input is connected, the inverter will automatically detect it and begin charging the batteries (if needed) and transfer AC power to the loads.

5.2 AC/Battery Priority Settings

The inverter offers flexible priority settings:

• AC Priority (Default): When AC input is available, the inverter charges the battery and transfers AC to power the loads.
• Battery Priority: The inverter will supply power from the battery even when AC input is present. This is ideal for maximizing self-consumption from renewable energy sources.

These settings can be configured via the DIP switches or the optional LCD remote panel.

5.3 DIP Switch Settings

The inverter features five DIP switches for advanced configuration:

• SW1: Low Battery Trip Voltage (adjusts the voltage at which the inverter switches to AC input or shuts down).
• SW2: AC Input Range (sets the acceptable voltage range for AC input).
• SW3: Output Frequency Setting (50Hz or 60Hz).
• SW4: Power Saver Setting (enables or disables power saving mode).
• SW5: Utility/Battery Priority.

Refer to the detailed table in the full manual for specific DIP switch combinations and their corresponding functions.

5.4 LCD Display

The integrated LCD display provides real-time operational status, including input/output voltage, frequency, battery status, and load percentage. It also allows for parameter adjustments.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your inverter charger:

• Keep the inverter clean and free from dust and debris. Ensure ventilation openings are not obstructed.
• Periodically check all electrical connections for tightness and corrosion.
• Inspect battery cables for any signs of wear or damage.
• Monitor the battery bank's health and ensure proper charging cycles.
