Camper Van Electrical – Handling a LARGE Inverter

Handling a large inverter

Inverters up to about 1800 watts can be hooked directly up to one of the four Bluesea Safety Hub higher amperage terminals. As we have done here…

But the Hub cannot handle larger inverters than this due to the high amperage. An easy way to hook up a larger inverter (say a 2 or 3 thousand watt one) is to hook the inverter directly to the house battery. One of these dual terminal fuses can be used with one fuse for the Safety Hub and the other for large inverter.

One thing to bear in mind for larger inverters is that more battery will be required to run them. A 3000 watt inverter is going to pull about 300 amps when running at full power. The maximum recommended discharge current for the 100 amp-hr SOK batteries that we show in the base system is 100 amps – four of these batteries is the least I would try to run a 3000 watt inverter on.

Give some thought to whether you really need something like a 3000 watt inverter – things get harder and more expensive throughout the system when you do this.
