Overland Solar Systems designed and installed a system in our Class C RV which has completely changed our boondocking capabilities. They worked closely with us to give us the power we needed within our space constraints. We now have 400 Ah of lithium with a 3000 watt inverter and 400 watts of solar. We are able to run all of our electrical devices. We are now able to boondock without running our generator which we love.We feel very happy with the service and support we have received from Overland Solar Systems and would gladly use them again if our needs change.
