Solar Charge Controllers. Solar charge controllers are designed to do two primary things within a solar power system: optimize the charging of your deep cycle batteries by the solar panels and prevent electricity from the batteries from going through the solar panels when there is no sun.
We can change sunlight directly to electricity using solar cells. Every day, light hits your roof's solar panels with photons (particles of sunlight). The solar panel converts those photons into electrons of direct current (DC) electricity. The electrons flow out of the solar panel and into an inverter and other electrical safety devices.
