For light battery maintenance, you can see a hatch accessible from the exterior, but to replace batteries, it will be necessary to remove the enclosure. Each battery is extremely heavy, close to 90lbs so make sure to position them over the axles for even weight distribution.Ībove is the unfinished battery box, once stained properly and fit flush to the wall, it will add a nice aesthetic to the interior and will also provide a base for some shelving. Four batteries of that size, would store a huge amount of power. There are two batteries in parallel sequence now, but there is room for an additional two in the battery box. Though it’s not required to vent AGM batteries, I did anyway and then built a large insulated box around them. The solar panels charge two 155ah deep cycle AGM batteries located inside the trailer.
#AIRSTREAMER CONTROL PANEL FULL#
I tested the panels in the worst possible conditions – completely overcast, rainy, and later in the afternoon, and they still were able to draw 19.9v, enough to maintain a full charge with normal usage. These three are large panels and should provide plenty of power. Each panel is 160watts, totaling 480 watts, though there isn’t any more room on the roof, it is possible to expand on this system with ground based panels. There are two main sources for electricity in the trailer: solar and shore power (shore power is when you are actually connected to an external power source like regular city power from a house, etc.)īelow is a view of my solar panel configuration.
In a previous post I mentioned that there are several systems involved, today I will explain what they are and how they interact with one another. In this post I will detail all of the electrical work required to power my updated Airstream.
