How it all works
Three ways in, one way out
Driving: the 40A DC to DC charger charges the van’s lithium from the tow vehicle. Powered site or home: the 40A Pro Series charger takes over from 240V. Off-grid: the 3000W inverter turns the battery into 240V for your appliances.
- ✓Inverter has a built-in RCD and automatic transfer switch (ATS): plug the van in and it switches to mains power
- ✓Pro Series batteries: Bluetooth app and active cell balancing
- ✓Inverter wiring kit sized for the 3000W inverter, with MEGA fuse and holder
- ✓Two batteries in parallel: connect them with equal-length cables

Inverter sizing
Why this inverter suits this battery
How big an inverter a battery can run depends on its continuous discharge rating (the BMS), not just its amp hours. As a guide, 100A continuous suits about a 1000W inverter, 150A about 1500W and 200A about 2000W.
- ✓Batteries: 2 x 200Ah Pro Series, 200A continuous BMS each (400A together)
- ✓Inverter in this kit: 3000W
Air conditioning
Runs your van’s air conditioner
Most newer inverter caravan air conditioners draw about 700W once they’re running. This kit runs one for about 4 hours from a full battery. For longer, choose a kit with more amp hours.
- ✓200Ah kit: about 2 hours
- ✓400Ah kit: about 4 hours
- ✓600Ah kit: about 6 hours
Run times are a guide. They depend on the air conditioner, the weather and what else is running.
Compatibility
- ✓Caravans, campers and motorhomes
- ✓Tow vehicles with standard or smart alternators
- ✓240V appliances within the inverter’s rating, including most inverter air conditioners
