We’ve slowly been increasing our solar game.
After getting the work vehicle fully upgraded with an extra battery, permanently mounted 300W panel and wiring upgrades (so we can power big tools and the ultra vital espresso machine) we have turned our focus to building the Ra Accumulator.
This is a modular PV (solar) system capable of running Whisper Tree and many of our other LED / sound sculptures. It uses mostly second hand panels / batteries and is scalable to provide 12 / 24 DC or 240 AC inverter power as needed.
