Split charge relay
Volt sensing relay for charging leisure batteries from the engine. This is a decent heavy duty one that has never failed me
Midi fuse holder
I use midi fuses for my main battery fuses. This holder lets you conveniently mount the fuse on a nearby surface
Pure sine inverter
The best inverter I've tried so far. It's low noise and has eco-mode.
Automotive cable
For the split charge cable use at least 16mm size cable
Crimp connectors
For terminating automotive cable for connection to battieres, and possibly other things
Heat shrink sleeve
For insulating crimp terminations.
Use these if you don't have a roofrack to mount your solar panels on to
This fusebox has a built-in negative busbar and easily enough fuse slots for most conversions
Cable ties
I use these a lot to keep everything neat and tidy – messy wires are confusing and stresssful
For the main fusebox. It's handy to keep a selection of these fuses for spares
These are the lights I have. Low profile and low power consumption. They don't have a blue hue like most LEDs
This is the current solar panel I have. I think it's a great size vs power combination AND it's a great price
Solar charge controller
This has been the best solar controller I've used so far. I should have got this one in the beginning
To have efficient USB charging in your van – instead of plugging your charger into the inverter
The neatest way to bring the solar panel cables through the van roof to inside.
For connecting two solar panels together in parallel
Electrical tape
Always handy. You can use it if you don't have any heat shrink sleeving, to finish around crimp connections
Multimeter
Essensial for finding faults when/if things go wrong
I use this when my van is connected to mains hook-up. Now discontinued. Link is for the updated version
I keep one of these on my roof so I can connect to mains power if it's available.
Mains incomer
To safely bring mains 'hookup' power inside the van. Inside is an RCD and MCB
Used as a main cut off swtich from the batteries – aka 'battery isolator'.
