Solar TV and fan with a 300 W inverter, under ₱30,000
Open in the lab ▸Make my own copy
Watch TV and run an electric fan from the sun. A 200 W panel and a 20 A MPPT controller charge a 12.8 V 50 Ah LiFePO4 battery (640 Wh); a 300 W pure-sine inverter makes 220 V for an LED TV (about 100 W) and a desk fan, and the controller’s own 12 V output runs a bulb and a phone charger. Enough for an evening of TV and a fan through the night. Not for a rice cooker or a flat iron: those take 600 to 1,000 W. Every part is on the bench, and Buy all the parts (on the project strip, or Menu → Make) lists them with an estimated price and shop links. Estimates are for the Philippines; check each listing before you buy.
