Hey Portal members,
I'm finally coming out of the closet and posting. I've just spent the last few days going over all the threads in this section that have to do with dual batteries, inverters, solar and alternators. Lots of great information which is how I came up with a wiring diagram for installing an inverter in my truck and solar on my truck camper. I have a month and a half to get this installed. I hope some of you can look it over to see if anything is going to cause a fire or if I need to add or delete anything.
The truck, a 2002 F350 powerstroke 7.3L with dual alternators, is mainly used for work, so that's the reason for adding an inverter. I separated the two alternators so they're able to charge different battery banks independently. I made the lower alternator the primary alt. to charge the start batts. I did this because I couldn't find a HO alt for that location and I figure the stock 110 amp alt should be able to keep the start batts topped off if all the truck's electronics are routed to the house batts. I have a DC Power 270ampXP alternator that will be used as the upper alt.
A few questions:
I would like to combine the batteries in case I need a jump or if one of the alternators goes bad. Is the Blue Sea ACR a good choice for this?
Do I need a fuse from the 110amp alternator to the powerpost or can I tie into the fuse that's coming off the 270 amp alt?
If the house batts get drained to 50% and I go to start the truck and the batt banks combine, will they equalize and start charging equally or will the start batts get overcharged? If the ACR is switched to off, is this even an issue?
Is some kind of regulator/A2B charger needed to charge the house batteries with the alt?
I read that it's a good idea to run a neg wire from the house batt to the alt mounting bolt. Does this need to be wired into the shunt? If so, what side?
I plan on using Anderson connectors for the solar connection between the truck and camper. Are there any special crimpers that I should be using on 10ga and bigger connectors?
Thanks for looking.
