I have been given a 250W solar panel with a maximum output of about 44V. I believe there are two types of controllers (MPPT, PWM) but don't know anything about them and don't want to spend a lot of money on one, as my main aim is main to provide garage lighting.
- I can make a charger for the 12V lead-acid battery (probably from a circuit on this site ).
- I can connect 12V LEDs to the battery.
- I have an inverter if I want 220V AC for lighting or an electric drill.
