Solar controllers

Always keep your battery under control.

Thanks to our solar charge regulators you can have greater control over the batteries in your installation. You can be sure that you are extending their useful life by constantly monitoring the state of charge and/or the intensity of the charge.

At Techno Sun we have the best brands of MPPT solar charge controllers and PWM solar charge controllers.

How does a solar 
charge controller work?
What is a solar charge controller for?

The solar charge controller is responsible for controlling the flow of energy between the solar panels and the solar batteries avoiding overcharging and maintaining the optimum point of charge and discharge. This is done by controlling the current and voltage parameters and will depend on the state of charge of the battery and the energy produced by the solar panels.

How to choose a solar controller?

There are currently two types of solar charge controllers available for solar photovoltaic systems: the MPPT solar controllers (Maximum Power Point Tracker) and PWM controllers (Pulse Width Modulation).

Depending on the type of installation and its capacities, it will be advisable to opt for a type of regulator with characteristics that can maximise its full potential. For example, for small solar installations PWM is usually used due to its cost advantage, while for larger installations M fvPPT is usually better, as despite being more expensive, its efficiency is superior. That is why we recommend contacting us to receive personalised suggestions for each of the different situations.
