This client asked us to install as much solar power as possible on the roof of their Winnebago View. The space was pretty limited, but we managed to install three Zamp Solar 170W solar panels, providing a total of 510W of solar power. Ideally, we would recommend a 400Ah battery bank with this system to provide enough power to manage their frequent microwave and hair dryer use. Due to space constraints there was only enough room for a 300Ah battery bank, which we placed underneath their top step. Due to the height of the LifeLine AGM batteries we had to modify the lid to the compartment housing the batteries so that the battery terminals were not going to be touching a metal lid. With this accomplished, they are able to use their microwave and hair dryer, they will just want to monitor their power usage to ensure they are not draining their batteries more quickly than they would like.
This client was looking for something small and relatively inexpensive to keep his batteries charged and in good health. To accomplish his goal, we installed 360W of solar charging power along with a 25A Blue Sky charge controller. He’ll also be able to use the added solar power to help run some light DC loads.
The pictures in this post show the steps we had to take in order to upgrade this client’s battery bank from two 12V wet cell batteries connected in parallel (150Ah) to their new battery bank comprised of two 6V Lifeline AGM GPL 6CT batteries (300Ah) connected in series. The battery bay was too small to accommodate the new AGMs without modifying the bay lid. A plasma cutter was used to remove most of the metal top of the battery bay so that the battery terminals would not touch the metal lid. Now there is just enough room for the new the batteries to fit, thus doubling their battery capacity as a result.
