Hi everyone, I just finished converting a small campervan and want to add a couple of extra perks here and there. Recently I stumbled upon 12vdc heating elements, and think this is the perfect solution to heat up my shower water (20 liter deposit). However, the element drains a lot of my battery energy (its rated for 300W and can be configured for 150w). So now I’m thinking of just having it wired straight to my 150w solar panel and having a manual toggle switch to divert the pv energy between my solar controler and the heating element (with a fuse in between).
I’m looking into DPDT toggle switches, but I can hardly find 12vdc (found one with expensive shipping rates) with high amperage tolerance (say 25A). So I started to question if these are uncommon for 12v systems.
There are however, many SPDT switches for12v systems. But making this connection means I need to split my positive pv energy using a Ymc4 connector. And this is where I’m not sure what happens to the pv energy going into my battery bank if I split the positive solar cable in two just before the toggle switch.
Would be apreciate of any advice regarding the two options. I want something simple as turning a switch on or off to divert the solar power. Not looking into automatic relays or diverters or anything of the sort.
Thank you in advance
