Do I have everything in my cart for my setup?

[Ross&Hailey]

So I am working out a solar setup for my custom built Skoolie/RV and would like some input from you guys.
Here's a list of things that I plan on using in my setup, and wonder if there is anything you can see that I'm missing.

-4 340 watt residential solar panels
-3000 watt 24 volt victron inverter charger.
-MPPT charge controller (which would you guys recommend for this setup)?
-8 Duracell GC2 215 AH 6v golf cart batteries (Flooded Lead Acid) (set up as 4s2p?)


How many amps should my MPPT charge controller be? And what else am I missing?

In case you need to know (I'm still learning all of this) the info sticker from the solar panels contains this info: (Open circuit 46.4v, pmax:38v. Short circuit current 9.49 A, current at pmax: 8.95 A)
Any advice or pointers are welcome. Going lithium is not an option for me due to cost up front.

My only comment is 340w panels are large and usually need to be mounted the full width of the bus. This leaves no access to the roof for what ever reason. I have smaller panels that leave a 2' walkway down the center of the roof.

I already have the panels and they were the best bang for my buck that I could find. Curious to know why you feel that roof access underneath the solar panels would be necessary.

.

Have you considered LiFePo batteries? More money, much, much longer lasting; less room and weight.

Always interested in the thought process behind the design.

A lot of the issue is the cost. As I stated in the post. Another thing is, from my research, a lot of people have had Flooded Lead acid batteries last years for 1/10th the cost up front... I only plan on doing this for 5 or 6 years so Lithium doesn't make logical sense financially.

Not underneath, but access to the roof itself for what ever reason. My smaller ones run down each side and I can walk the roof front to rear.

1360 watts @ 24v is 57 Amps so I would look at a 60a charger controller. Victron 150/60 smartsolar or blue solar would be appropriate. Smart versions have Bluetooth built in. You’ll likely never or rarely see 60a charging so you don’t have to worry about exceeding the rating.

Also you need a battery monitor. Victron smart shunt is what I use but there are others with displays that might be nicer.
