Are connection cables included in the kit?

To support more flexible DIY installations, connection cables are not included in the kit. Customers can select suitable cables separately based on their specific system requirements.

What can this power kit run?

This system can power common motorhome essentials such as fridges, lights, TVs, laptops, coffee machines, CPAP machines, water pumps, and other small appliances while travelling or camping off-grid.

What’s the difference between the 2000W Inverter and the 2000W Inverter Charger?

The standard inverter converts 12V DC battery power into AC power for appliances. The Inverter Charger also includes a built-in battery charger and automatic transfer function for shore power or generator charging.

Does the Inverter Charger require additional components?

Only the High-Surge Inverter Charger requires an external N-G Bonding Relay and an RCD/RCBO for installation. Please refer to the installation guide in the Manuals Center for details.

Is the battery suitable for cold weather use?

Yes. The Core Mini LiFePO4 battery includes low-temperature charging protection and an IP65-rated design for reliable use in outdoor and mobile environments.

Is this kit suitable for off-grid camping?
