Pasting text into windows NOTEPAD and copying it out, will remove formatting if there is no other way.

As to your voltage question, you're fine. That's what MPPT controllers are designed to do. Step down the higher voltage input to match your battery voltage. All well here.

As to your refer question, you're not looking good. The refer draws .95 amps , but at what voltage? If at 120 volts you are needing to factor in the voltage inversion from 12 to 120. Now we're talking 9.5 amps. This is before all the inherent inefficiencies involved in making the power and inverting it. Now consider your less than optimum panel angle being flat on the hot roof of your van and the fact that you may not get more than 4 sun hours in a good season with your van sitting in the hot sun. Do you want your refer running 24 hours a day? Your proposed 2 100 watt panels will struggle to, and probably not make 9.5 amps for said 4 hours a day. 24 hours run time would require 6 times more solar and a considerably larger battery bank. If the .95 amp rating is at 240 volts, then you're talking needing 19 amps @ 12 volts from your batteries so you can double these numbers..

You can buy a lot of ice for what it will cost to assemble a system to run a refer in a van.

Isn't the Dometic refrigeration unit a 12-24v unit? Why would you need to run an inverter?

Hi Logan,

[Logan5]

Yes, You could even consider running a 24v battery. 6 amps at 12 volts is only 3 amps at 24 volts. equals less resistance equals higher efficiency

You need to present accurate info if you want accurate answers.

My apologies. First day on the site.
