What are the functions of the solar controller?

The detailed functions of the solar controller are shown below: Load over-current and short-circuit protection: When the load current exceeds 10A or the load is short-circuited, the fuse wire melts and can be used again after replacement.

What is a solar charge controller?

A solar charge controller is a critical component in a solar power system, responsible for regulating the voltage and current coming from the solar panels to the batteries. Its primary functions are to protect the batteries from overcharging and over-discharging, ensuring their longevity and efficient operation.

How does a solar battery controller work?

Based on this information, the controller adjusts the power output from the solar panels. When the battery is near full capacity, the controller reduces the charging current to a trickle, allowing for a gentle top-up that keeps the battery full without causing damage due to overcharging.

Is a charge controller necessary for solar panels?

A charge controller is pretty much obligatory for a solar panel system. The only exception is when the battery capacity greatly surpasses the wattage of the panels, like in solar vehicles, and there is basically no risk of overcharging it.

What are the features of charge controllers used in autonomous solar plants?

The following parameters define the most common features of charge controllers used in autonomous solar plants: Battery overload protection (high cut-off): this is the essential function of the controller. It prevents the battery from heating up, losing water from the electrolyte and the plates from oxidizing.

How does a photovoltaic controller work?

For an intermediate voltage value, the controller enables a fraction of the current produced by the photovoltaic panels to pass, which is smaller the closer the voltage of the battery terminals is to the maximum regulation value.
