Going solar

I have a 2015 Voltage 3990 toy hauler. I am wanting to install two 100 watt flexible solar panels, a 100 volt-50 amp charge controller, four AGM batteries, and a new Progresive Dynamics intelipower 70 amp converter. My question is will the power control system, the one that sheds power if the draw is to much on the generator, I have in the coach cause problems if I install an inverter also for a/c power, i.e. a magnum pure sign 4000 watt hybrid?

Welcome to the forums!

I am not familiar with the power management systems, hopefully one of the other members that has one can answer that question. I am going to say that you may be a bit light at 200 watts of solar with a 4 battery set up. My rule of thumb on solar is 80-100 watts per battery in most cases.

You are definitely headed in the right direction with the PD converter, the stock WFCO work, but that is about all they do.

A 100volt charge controller? For the system and use your talking about, your under paneled. 200watts of solar will take most of the day to top off your batteries (in the winter, spring & fall) with some other minor loads on the system. You need more like 6 of those panels. You didn't say what voltage your panels were.

Why would you use a 100 volt charging regulator on a 12 volt system? I have a 25 amp 12 volt outdoor rated solar charging controller. I have one 100 watt flexible solar panel which is enough to not let my batteries run down with the vampire voltages.

Sounds like a partial description of a MPPT controller versus a PWM one.

Your LMS (Load Management System) will function just fine using the inverter as it will not know what is supplying power. But you won't run but for a few seconds if at all an AC unit from the inverter on 4 batteries. I have 4-6v batteries, 4 panels totaling 370 watts and a 3100 watt inverter and don't run air. Made the mistake once of leaving the AC on when switching over to inverter power - shutdown pretty quickly.

I'm considering putting a few 100 watt panels on the roof of my Voltage. Any recommendations on how to secure them with out damaging the roof?

I used EternaBond! Will never come off but ... I used the flexible panels (100 watts) that can be daisy chained for more.

What flexible panels did you choose?

High Power 100W 18V Solar Panel
Store: channy trade
Quantity: 1

I bought it off a website called WISH. Since my charge controller was outside mounted on the frame near the battery, I searched for an IP-66 rated device and found one for about 20 bucks. I purchased the cables for the solar panel separately also. All in all, I have less than 150.00 invested and it works fine.
