The main function of a solar charge controller is to ensure the amount of power that is sent to the battery is enough to charge it, but not so much that it increases the battery voltage above a safe level. It does this by reading the voltage of the battery and calculating how much additional energy is required to fully charge the battery.
During the night or when solar panels are not producing electricity, there is a risk of reverse current flow from the battery back to the panels. Solar charge controllers prevent this reverse current flow, which might discharge the battery. Applications Solar charge controllers are a vital component in various solar energy applications.
The chief function of a controller is to protect your batteries. Since batteries are the most expensive part of a solar power system, you want to protect your investment. Unlike batteries or inverters that have several types, controllers are much simpler in that you have two options to choose from.
If you want to have batteries as part of your home solar system, you’re going to need a charge controller. The chief function of a controller is to protect your batteries. Since batteries are the most expensive part of a solar power system, you want to protect your investment.
It does this by regulating voltage and current. It stops your batteries getting overcharged by controlling the flow of energy from your solar panels. It also stops the reverse flow of power, which can drain and damage the battery bank, from your batteries to your solar panels.
Solar regulators, also known as solar charge controllers, are obligatory devices for a solar panel system. Their main function is to manage the charging process of the battery: they prevent overcharging and ensure the battery is not used when empty.
