This was just a standard solar charger installation. The customer now has 320W of solar going through an MPPT charge controller. Also, while working on the rig we noticed that the customer’s flooded batteries were badly sulfated. We are currently running them through an equalization to restore some of their life. In a year or so, this customer may be back for an AGM upgrade. Flooded batteries require a lot of maintenance.
This customer came to us with a price ceiling and asked that we give them the most power possible for their budget goal. Upon inspecting the trailer, we found that their batteries were completely dead. We replaced them with a pair of low cost Interstate Flooded batteries and added two 100W panels to the roof with a 25A SunRunner Signature MPPT core. The system can easily be expanded with the addition of two more 100W panels when the customer is ready.
