Adding more Solar and DC-DC charger

Hope all is well guys and girls

About 6 months ago i came here with a plan to leave my high priced NYC apt and move into my truck camper full time , well , its been one hell of a ride so far !

Over the last few months ive payed close attention to my energy needs , i have 400w of solar which pulls about 15amps MAX on the best conditions

I have a 280ah lithium battery pack

and a propane generator that i use for emergencies (to charge the battery if its been cloudy) or on hot days if i want to turn on my ac

I am never hooked up to power at a campground , everything is done off the grid



So ive gotten a bit tired of having to position myself in the sun, my life revolves around this battery and its getting old , so heres my plan


add 2 additional 200w panels , upgrade the existing SCC to a victron 100/50

add a 200amp high output alternator and a renogy 60 amp dc to dc charger



My current setup is a 2006 Ford f350 paired with a 2019 Eagle Cap 811


The purpose of this post is to say hello again , and also get any tips or suggestions on the best way to proceed


I am in the process now of doing the resarch to configure the system correctly , so not only will i be reworking the solary array and SCC but also trying to size the correct wiring and get a good plan for the DC-DC charger as well

thanks again

  • Hello again! Does your energy use survey indicate that 600 watts will do the refill most days? If so a new alternator (expensive) may not be needed. And it can be added later. Lastly, 15 amps from 400 solar watts with batteries in bulk and good sun doesn’t seem right IMO.
  • Solar = aka The 'Black Arts'... heheh

    Went through and still going through it..

    Lesson's learned from my experience,

    - Put as many panels as you can handle and the new 200w would be my choice
    - Whatever wiring one suggests, plan for the highest and then go one grade higher (lower number)
    - Look at the 3000 w invertor/controller..
    - Do what you can with the batteries..

    All that so you don't have to 'Rewire/re-configure' the system if you need more add-ons etc... If you don't want to go the full panels, make sure the wiring would handle the max so later on, you might want to ADD another one
