We have a new TT (2109S) which has an increased power demand over our previous chalet aframe and I am eventually going to add a permanent solar system to the trailer but in the mean time wanted to start to piece together the components.
We are running 2x 225ah 6 volt's and are currently trying to maintain those with a portable 90watt folding panel which isn't enough supply to keep the batteries full for early season furnace use in Canada for more than 3 days should the sunlight be minimal. Rough estimation is 45-50 ah of use per day.
First thing I wanted to add is a quality monitor to properly determine our ah use then I can be better prepared to size the panels. Likely going to be 2x100watt but want to really see what we need.
The two monitors I have been looking at are the TriMetric TM-2030 RV and the Xantrex LinkLite. Both are roughly the same cost the Xantrex comes with a shunt. I am open to other monitors but really want to keep the user end simple so the DW can operate them as well. I am usually good at finding comparisons on the web but these products do not seem to have as many head to head reviews.
Any help is welcome
