Off-Grid Cabin - Washington County
The system for this cabin was installed in an outbuilding that used to serve as a small bunkhouse, prior to the main cabin being constructed. Before we installed this new system, the cabin had an extension cord wired to the main panel which was powered by a portable power station by day and a small generator by night. It was a lot of work to maintain somewhat constant power, so we helped add a reliable and permanent solar powered system.
We optimized the bunkhouse roof real estate by using 320W solar panels; maximizing the solar production in the available space. The eight panels charge four 48V lithium iron phosphate batteries, which allow the cabin to have power and Starlink internet when the sun is down. We also installed a generator inlet for a generator to power the cabin and charge the batteries as needed. The 5,000VA inverter is enough to make electricity in the cabin feel like a normal home without breaking the bank. Fortunately underground conduit was already installed from the bunkhouse to the cabin which allowed us to easily connect the inverter output to the main electrical panel. To top it off, we installed a touchscreen system monitor and provided a dedicated tablet to wirelessly monitor the system from the cabin itself.
We're optimistic that with a reliable off-grid solar system, future cabin visits will be a lot more comfortable and a lot less stressful!
