Suitable Applications

Caravan, RV, marine, backup and off-grid power systems.

Operating demanding 240V appliances when battery capacity and installation are suitable.

Systems requiring automatic AC transfer, Grid Boost and battery charging from AC input.

Power Source and Battery Requirements

Use only a suitable 12V DC battery system.

Battery capacity guidance: 12V battery banks; lead-acid 100–2400Ah and lithium 100–1200Ah charge capacity range listed in the manual.

Ensure the battery is fully charged and in good condition before operating high loads.

High-power appliances draw very high DC current. Undersized batteries, cables or fuses can cause voltage drop, shutdown or battery damage.

Runtime guidance: Runtime depends on load and battery capacity.

Installation Notes

Install the unit in a dry, cool and well-ventilated location.

Keep ventilation openings clear and do not mount the unit where heat can build up.

Install the correct fuse or circuit breaker as close as practical to the battery positive terminal.

Use the cable size and installation method specified in the instruction manual.

Check polarity carefully before connecting the DC cables.

All 240V AC wiring must be completed by a licensed electrician.

Operating Instructions

Make sure all connected appliances are switched off before turning the inverter on.

Turn the inverter on and allow it to start normally.

Connect or switch on appliances one at a time.

Do not exceed the continuous output rating or peak surge capability.

If a fault occurs, switch the unit off, remove the load, correct the cause and restart the unit.

Common Troubleshooting

The inverter/charger will not power the load. What should I check?

Confirm the battery voltage is within the DC input range.

Check the AC input, AC output and DC battery connections.

Confirm the connected appliance is within the inverter rating and surge capability.

Check whether the RCD or external protection device has tripped.

The unit is not charging the battery. Why?

Confirm AC input is present and within range.

Check the selected battery chemistry and charge settings.

Confirm battery capacity is within the suitable range listed for the model.

Inspect battery temperature sensor and temperature compensation settings if used.

What is Grid Boost?

Grid Boost supplements limited mains or generator supply with inverter power when the AC source alone cannot support the load.

Reduce the connected load if the unit still overloads or the AC source cannot provide sufficient support.

Safety Warnings

Read the instruction manual before installation or use.

Use the inverter in a dry, cool and well-ventilated location protected from rain, water, dust and excessive heat.

Do not install the inverter in the same compartment as batteries or flammable materials.

Always use correctly sized DC cables, fuses and secure connections.

Do not connect the AC output to fixed building wiring, mains wiring, or another inverter output unless the manual specifically allows the installation and it is completed by a licensed electrician.

High AC voltage is present during operation. Do not open or service the unit unless qualified.

Reverse polarity connection can damage the inverter and may not be covered under warranty.

All 240V AC wiring must be completed by a licensed electrician and must comply with applicable electrical standards.

Warranty Information

The Projecta INVCHR2 is listed with a 5 years warranty under normal use. Warranty does not cover damage caused by incorrect installation, reverse polarity, misuse, modification, overload, water ingress, physical damage or failure to follow the product instructions.

Contact Support

If the issue continues after completing the troubleshooting steps, stop using the inverter and contact Projecta support.
