This unit is an advanced unit that combines a powerful 2200W pure sine wave inverter and an ultra-fast 1800W AC battery charger. Its "bi-directional" capability means it can intelligently manage power flow in two directions: converting 12V DC battery power into 230V AC for your appliances, and using 230V AC shore power to rapidly charge your 12V batteries.

You can purchase the KickAss 2200W Bi-Directional Inverter-Charger directly online through our website, call our sales team on (07) 3123 4715, or find a KickAss Store near you.

A standard inverter only converts DC power to AC power. Our bi-directional unit does that and much more:

• Inverter: Converts 12V DC to 230V AC.
• Charger: Uses 230V AC to charge your 12V batteries.
• Power Management: Intelligently prioritises power for your appliances over battery charging when shore power is limited.
• Transfer Switch: Seamlessly switches between shore power and battery power.

Yes. The inverter-charger has integrated Bluetooth, allowing you to connect to it using the KA Charge smartphone app. This allows for remote monitoring, configuration, and control of the unit.

Yes, the optional KickAss Smart LCD Remote Switch is compatible with this model. It allows you to conveniently turn the inverter on and off, view the total output power, and check the charging status via LED indicators from a different location within your vehicle or setup.

This is a key feature of the bi-directional design. When running on shore power, the unit intelligently prioritises supplying power to your connected AC appliances first. Any remaining power capacity from the AC input is then used to charge your battery. This ensures your essential equipment keeps running smoothly without nuisance trips, even if the shore power supply is limited.

Yes. The 2200W Bi-Directional Inverter includes two built-in USB-A ports that provide a total of 18W, allowing you to charge smartphones, tablets, and other accessories.

Below are the key specifications for the KickAss 2200W Bi-Directional Inverter-Charger.

This 2200W Bi-Directional Inverter-Charger is designed with comprehensive protection features for safety and reliability:

• Integrated RCBO: Provides combined Residual Current (earth leakage) and Overcurrent (overload/short-circuit) protection.
• DC Protection: Protects against battery under-voltage, over-voltage, and reverse polarity.
• AC Protection: Protects against overload, short-circuits, and AC under/over-voltage.
• Thermal Protection: Shuts down if operating temperature is too high or too low.

The inverter-charger is compatible with most common 12V deep-cycle battery types, including:

• LiFePO4 (Lithium)
• AGM
• GEL
• Standard Flooded Lead-Acid (STD)

Important: you should only use batteries with a maximum charge rate above 47A, as this is the lowest charge rate on slow mode. Additionally, as the inverter draws up to 2200W, your battery bank must be sufficient to support the discharge rate, and large enough to maintain charge based on your usage habits. 

For portable, plug-and-play use (connecting via the supplied AC and DC leads), a licensed electrician is not required. However, any fixed or hardwired AC installation into a vehicle, caravan, or building MUST be carried out by a licensed electrician to comply with Australian wiring standards (e.g., AS/NZS 3000 & 3001).

You can select the charging mode using the KA Charge app or the Mode button on the unit by pressing and holding the button.

The inverter may have shut down due to a built-in protection feature. Check the following:

1. Overload: The connected appliance(s) may have exceeded the 2200W continuous rating or the 4400W surge rating. Reduce the load and restart the unit.
2. Low Battery Voltage: The battery may be depleted, causing the inverter to shut down to prevent excessive battery discharge. Check the battery's state of charge.
3. Overheating: The unit may have overheated due to a heavy load or poor ventilation. Ensure the cooling vents are clear and allow the unit to cool down before restarting.
4. Loose DC Connection: A poor connection to the battery can cause a large voltage drop under load, triggering the low-voltage protection. Check that all DC cables are tight and secure.

Always check the KA Charge app to see if there are any error messages/alerts, these will clearly inform you as to why your inverter shut down. 

If the battery isn't charging, check the following: 

• Ensure the 230V AC shore power supply is switched on and properly connected to the IEC input.
• Check whether the unit's AC input circuit breaker has tripped.
• Open the KA Charge app and ensure that a charging mode (Fast or Slow) is enabled and the correct battery chemistry is selected.
• Make sure the battery is not already fully charged.
• If the AC output is maxed out, there will be no available current to charge your auxiliary battery. 

If you're having trouble connecting to the KA Charge app, try these steps:

• Ensure the inverter-charger is powered on.
• Make sure Bluetooth is enabled on your smartphone and that it is within range (approx. 10 metres).
• Check that no other smartphone is already connected to the inverter, as it can only pair with one device at a time.
• Close and reopen the KA Charge app. If that fails, restart your smartphone and try connecting again.
