solar powered static caravan project filmed in Greece, 2011
Short video on putting together a small solar power system for a static caravan (135w panel)
What I didn’t show (and perhaps should have done) was that the mains 240v supply is also being produced by the invertor and plugs straight into the the standard mains coupling of the caravan, and thereby runs all the sockets and lighting rings.
its been upgraded since then. Here’s a circuit diagram for anyone interested though I dont take any responsibility for anyone harming themselves whilst attempting to recreate this
