Can you add a Maximum Power Point Tracking solar controller to any existing solar panel?
Eco-camper is not selling individual MPPT controllers at this stage as there is a shortage of supply. For solar panel suitcases, the controller has to be configured so that the battery power is switched to the MPPT controller BEFORE the solar panel is connected. If not it wont function correctly. As a result it would be difficult to have the controller mounted at the back or near the solar panel. Eco-camper has the controller in a separate bag as close to the batteries as possible.
