1. What is a Solar Controller?

A solar controller, also known as a charge controller, is a device that regulates the amount of charge that is sent to the battery from the solar panel. The controller ensures that the battery is not overcharged or undercharged, which can damage the battery and reduce its lifespan.
A solar controller works by monitoring the voltage of the battery and the solar panel. When the battery voltage drops below a certain level, the controller will allow more charge to be sent to the battery. When the battery voltage reaches a certain level, the controller will reduce the amount of charge that is sent to the battery. There are two main types of solar controllers: pulse width modulation (PWM) and maximum power point tracking (MPPT). PWM controllers are the simpler and less expensive option. They work by turning the solar panel on and off to regulate the amount of charge that is sent to the battery. MPPT controllers are more advanced and efficient. They work by constantly adjusting the voltage and current to ensure that the solar panel is operating at its maximum power point.
To build a 2000 watt solar power kit, you would need the following: solar panels and mounting hardware, an inverter, batteries, wiring and control systems, charge controllers and other accessories.
