Charge Controller
A device that regulates the voltage and current from solar panels to a battery bank, preventing overcharging and deep discharge. Common types are PWM and MPPT.
Why It Matters
Essential for off-grid systems, charge controllers protect batteries and optimize charging. MPPT controllers are 20-30% more efficient than PWM in real-world conditions.

Battery Storage
A system that stores excess solar energy for use when the sun isn't shining, providing backup power during outages.
Off-Grid System
A solar system with battery storage that operates independently from the utility grid, requiring full self-sufficiency.
DC (Direct Current)
Electricity that flows in one direction. Solar panels produce DC power, which must be converted to AC for home use.
