Mini off-grid all-in-one DIY solar power system - inverter + battery in one box

A compact all-in-one DIY solar power system: a single box holding the inverter and the battery bank, ready for off-grid use. I built it as a little emergency/garden power unit - charge it from a solar panel, and it gives you clean AC/DC power wherever there is no grid. Great for powering small loads when the mains is out, for the shed, or for a weekend off-grid setup. All DIY, no vendor lock-in - just a solar panel, a charge controller, an inverter and a battery, neatly packed in one enclosure.
