Long long Honeymoon which For their efforts rightfully so got some sponsors perks. 4 BB 100 were installed 400 watts of Solar and a Renogy 50 amp DC-DC charger. I believe you get that controllable regulation back to the batts. I now see a 60 amp version DIY solar Will had a pretty good review of a 40 amp. I was thinking 300 amps is a good start. Although bloggers Less Junk more Journey stuffed 600 amps into his Airstream. Iím sure with sponsoring help.
A VERY important question to answer please. As the inverter in our twin fb will be under the wifeís bed will I be getting a WTH is that noise or vibration from the 3000 Victron and forced to switch sides. LOL
Very nice install thanks for the pictures. Appreciate that.
QUOTE=daleyocum;2357767]I have a 2018 FC25 and started with 300ah of Battleborn being charged from 500w on the roof. I've since moved up to 500ah of Battleborn but that's just us. At level you just really don't have to think about power usage most of the time.
Similar to Wulfraat, I also have a Victron 3000 Multiplus
hybrid inverter, Victron solar stuff, etc. I also have a Honda 2000 generator as a backup.
We are fairly heavy users of electricity and use an induction cooktop, microwave, coffee maker, TV, hair drier, etc. We do run the AC for an hour or two to cool things off at night without having to run the generator. If it seems like it will be more than an hour, we fire up the Honda to supplement the solar and battery.
Since you are contemplating a sophisticated system, I'd recommend the Victron Multiplus 3000 rather just an ordinary inverter. That unit will mix battery power and shore power, like from a generator. It also takes the place of your current converter and charger. It's Lithium ready where as otherwise you'd likely need to upgrade your charger.
To answer your question, for our FC25 using power like we do exclusive of the AC, 300ah would have been enough unless you make a habit of parking under trees for extended periods of time. That's using an induction cooktop.
If you find it's not good enough, you can add more battery later, like we did, if you leave room. I'd advise doing it no more than one year later, though, so that your batteries will be fairly well matched.
By the way, getting 60 amps of charging current from your TV is highly dependant on that vehicle. My F150 is limited to around 10-15. Plus, remember that you'll need to some electronics to step that up to the 14.3 volts the Lithium wants.
In our FB Twin, I ended up with the batteries under our curbside twin along with the rest of the electronics. Here's a few pictures.[/QUOTE]
