Our RV Solar Components

Here is a list of Solar equipment on our RV. These components are the same that you would see used on an off-grid solar cabin or tiny house.

We initially started out with a single solar panel and a PWM charge controller. We have continuously expanded it over the years. Today we have roughly 500 watts of flexible solar panels on the roof, a 45 amp MPPT charge controller and 2000 Watt Pure Sine inverter. Here is a basic diagram of our setup.

Flexible Solar Panels
We have several flexible Solar panels on our roof that provide us plenty of power and full access to the roof. The larger UniSolar panels we purchased are no longer manufactured. Remaining inventory of Unisolar panels can still be found. We've since added HQST 100 Watt Flexible Solar Panels (seen in the photo).
Morningstar Tri-Star TS-45 MPPT Solar Charge Controller
This has been a solid solar charge controller for our RV. Our panels, when wired in series (versus parallel) output over 80 volts. This allows us to really take advantage of the MPPT features to convert the higher voltage to more charging AMPs. This controller can also handle up to 45 AMPs which will be more than enough for us as we expand our solar capacity.
Morningstar TS-RM-2 Charge Controller Remote
This remote control panel allows us to monitor our solar panel performance and access all of the charge controller functions from within the RV. We have it mounted just inside our entry next to our power inverter remote (Watch installation video).
Bogart Engineering TriMetric Battery Monitor
Having the ability to accurately monitor your battery usage is essential when relying on your battery bank for power. The TriMetric Battery Monitor tracks AMP usage to provide accurate state-of-charge readings back to you. We know precisely how many amp hours we have available at all times. This is the unit we use and rely on. To measure AMPs you will also need to install a shunt (below) near your battery bank and connect it to the monitor. Here is how we use the TriMetric in our RV (Video).
450 Amp Hour AGM Battery Bank
We have four of these six volt AGM batteries (225 Ah each) installed in a series/parallel configuration for a total of 450 amp hours of capacity. Together with our 2000 watt pure sine inverter we are able to run all of our electronics including my wife's blow dryer and our microwave oven.
Samlex 2000 Watt Pure Sine Inverter
To provide AC power from our battery bank, we installed a 2000 watt power inverter. This Samlex 2000 Watt Pure Sine inverter also comes with a nice remote control monitor panel that we installed the coach. There are many ways to hook up an invter in your RV. We wired ours directly into our shore power connection so that we could provide power to all of our AC receptacles. Here is how we have our power inverter hookud up (Video).
