Solar, Battery upgrade priority (other mods also)advice???

[Refresh345]

Hi there forum,

I am looking to thoroughly upgrade exterior, and refresh the interior, of my Sprinter T1N, Class B, motorhome. Once the Corona restrictions lift we want to move on in an effectively new 'home'

WE are working on various upgrades ($$ allowing)
The most important issue is installing the most potent solar & battery system we can.

Any advice you can all offer would be EXCEEDINGLY WELCOME and appreciated:


What is the highest potential solar and battery storage (Lithium) one could fit onto a Sprinter T1N?


I wish to use Lithium batteries instead of AGM.
Unless you all advise strongly against that.

The 2 batteries can weigh a maximum 100kg in total.
They must provide a, total, capacity of 550AH minimum

I already have a solidly crafted metal battery storage box in place just behind the rear axle.
I can store two batteries of 51cm x 27cm x 22cm


Though I am also considering the use of additional foldable & flexible solar panels, I first, need to install the maximum wattage/12v Amperage on the roof.

What would be the best system anyone has experience with and can, confidently, recommend.

Is 45AH produced, in full desert blasting mid-day sun, a realistic aim?

My thanks, in advance, for any advice you all can offer me.??

jdc1,

A very few folks are doing just that--using a Prius battery pack. It requires a greater knowledge base.

I wonder why a Prius battery pack isn't used in RV's? They would be less expensive than two 12v lithium batteries.

Heat is going to be a negative to the solar harvest. Solar is usually talked about in watts not amps. But 800 watts may be enough to meet your requirement "in the noon day sun" (mad dog's and Englishmen)

Li do not love heat either.

I doubt you can store 550 amp-hours of battery bank in a box that size. Unless the plates are made from "unobtainium".

Hi,

I'm not fond of Li batteries as I live where it gets cold.

“The most important issue is installing the most potent solar & battery system we can.”

You really need over 225 AHs every day? That’s a bunch of power for a B.
