Mate, don’t follow me hahha absolute Luddite propped up by some experts here!!@Chris1983 you're doing an amazing job, keep it up. I have a Hillside Birchover and have this thread bookmarked as you are paving the way for my install over winter. I didn’t think that I would be able to get all that kit under my drivers seat, as I have the diesel heater outlet exactly like yours, but you’ve given me hope. Thanks again.
You don't need 16mm², that's way overkill. Your MPPT is only the 15a model, 6mm² is fine.
Is this what I’d need for Solar back to front?
Yeah that's looking better, I presume the van is in the shade?Only had to drill one hole……
But
Ran a temporary wire all the way through. Solar reconnected. To positive and negative bus bar under driver seat.
I’ve got a bigger gauge wire coming tomorrow, presume I can just reattached local ground and run positive pulled same way as the temporary wire.
Presume a fuse on this sensible, what size is best? Presume near mppt
And I found a bad crimp (mine) had come off positive bus bar, so now all is back as was! Bloody long day of it!!
Do the following numbers look as they should?View attachment 255023
Yes, the fuse on the cable needs to go right next to your busbar, it's there to protect the cable run from shorts. The fuse on the MPPT only protects the device.Thank you. I’ve ordered some. I note the unit already has a 20 amp blade fuse underside of housing. Do I need an in-line as well?
I posted one earlier in the thread. Fuse needs to be higher than the planned current or it will keep blowing, but less than the max cable capacity or it isn’t protecting the cable. Remember, the fuse is to protect the cable from catching fire if it is overloaded (e.g. a short circuit providing max battery amperage).Is there an easy reference chart you guys use?
The fuse needs to be at the LB end of the cable run. Sorry if that’s what you mean but there was talk of a pos busbar at the rear.Yes, the fuse on the cable needs to go right next to your busbar, it's there to protect the cable run from shorts. The fuse on the MPPT only protects the device.
Ah yes, I meant next to the LB bus bar, not the one at the rear.The fuse needs to be at the LB end of the cable run. Sorry if that’s what you mean but there was talk of a pos busbar at the rear.
This is how my voltages show across the various boxes. Engine running, Orion off and solar panels isolated. Shunt and Orion are with the LB under the passenger seat, MPPT in the rear offside wardrobe (about 3m of cable away).True, a run of the correct sized wiring from the MPPT to the battery would be just as good as you say.
