5. Setup and Installation
Proper installation is crucial for the safe and efficient operation of your inverter charger. If you are unsure about any step, consult a qualified electrician or technician.
5.1 Mounting the Unit
- Mount the inverter charger in a dry, well-ventilated area, away from direct sunlight, heat sources, and flammable materials.
- Ensure at least 1 foot (30cm) of clearance around the unit for proper airflow and cooling.
- Mount the unit securely to a stable surface using appropriate fasteners.
5.2 DC Battery Connections
- Battery Type: This unit is designed for 12V battery banks. Ensure your battery bank voltage matches the inverter's input voltage.
- Cable Sizing: Use appropriately sized cables for your battery connections to minimize voltage drop and ensure safety. Refer to electrical codes or a qualified professional for correct sizing.
- Connection Order:
- Connect the negative (-) battery cable to the negative (-) terminal on the inverter.
- Connect the positive (+) battery cable to the positive (+) terminal on the inverter.
- Connect the other end of the negative (-) cable to the negative (-) terminal of your battery bank.
- Connect the other end of the positive (+) cable to the positive (+) terminal of your battery bank.
- Secure Connections: Ensure all connections are tight and secure. Loose connections can cause arcing and overheating.
5.3 AC Wiring Connections
- AC Input: Connect the utility grid or generator AC power to the AC input terminals. Ensure the input voltage and frequency are compatible with the inverter charger.
- AC Output: Connect your AC loads to the AC output terminals or use the GFCI outlet.
- Grounding: Connect the grounding terminal of the inverter charger to a reliable earth ground.
- Circuit Protection: Ensure appropriate circuit breakers are installed on both AC input and output lines as per local electrical codes.
5.4 Remote Control and Sensor Connections (Optional)
- LCD Remote: If using an optional LCD remote, connect it to the designated LCD remote port on the rear panel.
- Battery Temperature Sensor: If using an optional battery temperature sensor, connect it to the battery temp sensor port and attach the sensor to the battery bank for accurate temperature compensation during charging.
- Auto Generator Start: Connect compatible auto generator start wiring to the designated terminal if this feature is desired.
6. Operating Instructions
6.1 Initial Power-Up
- After all connections are securely made and verified, switch on the DC power from the battery bank (if a disconnect switch is used).
- Turn the main power switch on the inverter charger to the "ON" position.
- Observe the LED indicators for normal operation. Refer to the troubleshooting section if any fault indicators illuminate.
6.2 Configuring Settings (Dip Switches)
The dip switches on the rear panel allow configuration of various operational parameters. Refer to the label on the unit or the full user manual for specific dip switch settings for battery type, charge voltage, and power saver mode. Ensure the unit is powered off before changing dip switch settings.
6.3 Inverter Operation
- When the unit is powered on and no AC input is present, the inverter will convert DC battery power to AC power for your connected loads.
- Power Saver Mode: This mode reduces idle power consumption. When activated via dip switch, the inverter will periodically "search" for a load. If a load greater than 50W is detected, the inverter will fully activate. If no load is detected, it returns to low-power search mode.
6.4 Charger Operation
- When external AC power (utility or generator) is connected to the AC input, the unit will automatically begin charging the battery bank.
- Charge Current Control: Use the charge current control dial to adjust the charging amperage. This is useful for smaller battery banks or when using a generator with limited output.
- Multi-Stage Charging: The charger employs a multi-stage charging process (bulk, absorption, float) to optimize battery health and lifespan.
6.5 AC Auto-Transfer Switch
- When external AC power is detected at the input, the unit will automatically transfer the AC loads from inverter power to the external AC source. This transfer typically occurs within 10 milliseconds.
- When external AC power is lost, the unit will automatically switch back to inverter power, drawing from the battery bank.
7. Maintenance
- Regular Inspection: Periodically inspect all wiring connections for tightness and corrosion. Clean any corrosion with a wire brush and baking soda solution.
- Ventilation: Ensure ventilation openings are clear of dust and debris. Clean with compressed air if necessary.
- Battery Maintenance: Follow the manufacturer's recommendations for your specific battery type. This may include checking electrolyte levels for flooded lead-acid batteries.
- Environmental Conditions: Keep the unit in a dry, cool environment. Avoid exposure to moisture, extreme temperatures, and corrosive fumes.
8. Troubleshooting
This section addresses common issues you might encounter. For more complex problems, contact AIMS Power technical support.
8.1 No AC Output from Inverter
- Check DC Connections: Ensure battery cables are securely connected and not corroded.
- Battery Voltage: Verify battery voltage is within the operating range (e.g., above low voltage cut-off). Charge batteries if low.
- Overload: Disconnect some AC loads. The inverter may have shut down due to an overload.
- Over-temperature: Ensure adequate ventilation. Allow the unit to cool down if it has overheated.
- Internal Fuse: If the unit is completely unresponsive, an internal fuse may have blown. This requires professional service.
8.2 Batteries Not Charging
- AC Input: Verify that external AC power is present and connected to the inverter's AC input.
- AC Input Breaker: Check if the AC input circuit breaker on the unit or external panel has tripped.
- Charge Current Dial: Ensure the charge current control dial is not set to zero.
- Battery Type Settings: Confirm dip switch settings match your battery type.
8.3 GFCI Outlet Trips Frequently
- Ground Fault: A ground fault may exist in the connected appliance or wiring. Disconnect appliances one by one to identify the faulty one.
- Overload: The connected load might be exceeding the GFCI outlet's rating.
