Charge Controllers Help Solar Panels and Batteries Get Along Why this small, overlooked piece of technology is key to setting up your solar and battery system for success.

A solar charge controller is a device found in a photovoltaic (PV) energy system that controls the amount of power that can be transmitted to an electric storage battery. By controlling the charge ...

Learn how to size charge controllers, inverters, and solar panels already on hand with a goal of future expansion.

The charge controller basically takes the erratic raw power produced by the solar panels and attempts to make it smooth before passing it onto the battery for storage.

A charge controller is fundamentally a simple idea. The goal is to charge a battery with solar panels, which means it’s essentially just a heavy-duty DC/DC buck converter.

This Low Dropout Voltage (LDO) solar charge controller uses a simple differential amplifier and series P channel MOSFET linear regulator –their compatibility seems like a marriage made in heaven.

Charge controllers with MPPT are essential components in solar power systems, managing the flow of charge to and from battery banks.
