This component, load regulator electronic device, also known as charge controller. What is its function? Protect the battery from overload of power or otherwise excessive downloads (over-discharging), what makes longer lasting life of this appliance and therefore the solar panel. Even prevents fire and explosion regulates energy with normal charging cycles especially in more than acid batteries gel batteries. Where we find them? Charging regulators found in our daily life, and can be found separately or incorporated in appliances in our daily lives within cell phones or a laptop Chargers powered by solar energy. In addition to protecting potential overload, these voltage regulators prevent deep cycle batteries suffer from excessive discharge. This makes it through an automatic cutting current that comes from batteries. They exist drivers that emit audible alarms and/or flashing lights most interesting signals.

How do they work? To deep cycle batteries reach peak load, the regulator will gradually disconnecting the passage of energy from the solar cells. Current regulators introduce microcontrollers for the proper management of a photovoltaic system. Once reached the full charge of the battery voltage value, controller injects a small current to keep it at full load, i.e. the current of flotation injected. This current is therefore responsible for maintain the battery at full charge and not being consumed energy is used to compensate for self-discharge of batteries. The disconnection of the consumption output by low battery voltage indicates a situation of discharge of the battery close to 70% of its rated capacity.

If the battery voltage drops below the control of consumption disconnection voltage value during more than one set time, is Disconnects the consumption. This is to prevent a timely short-term overload clear consumption. Available on the market in the market you can find a variety of models, classified by the current controlling (8, 10, 20, 30 A) and charge for 12/24V 16A to regulators. Another aspect of modern control units is the MPPT or maximum power of the traction point. This means that the controller determines the optimal working point of the PV curve. Operating voltage gives greater efficiency? A controller uses an advanced control algorithm that imposes new standards in solar recharging technology. The State-of-charge algorithm takes the battery temperature, voltage and discharge rate to determine the true state of efficiency of the battery. This pattern of sofware allows the driver to know the degree of sulphation of the battery. Some other features: autoflow for 12V or 24V systems automatic Equalization of batteries can be disabled when used bacteria gel or lead – acid type Matriculation protection against overheating and battery overvoltage, overcurrent of modules and overcurrent warning loads and low voltage LCD screen on models PR disconnect. Indicator light in three colors on Alpha, Gamma, Sigma and Omega models. Operating temperature: – 25 C to + 50 C Common size: 18.8 x 10.2 x 4.9 cm approx.
