PWM loading regulator Victron Blue Talar Light 20A 12V / 24V

Victron BlueSolar PWM LIGHT 20A: Efficient load management in 3 phases, Total electronic safety and optimized cost

In small-power photovoltaic projects - such as lighting systems, signage, small trimmered vans or insulated monitoring stations - components are required that combine an economic investment contained with maximum operative reliability. The Victron BlueBlocking PWM LIGHT 12V / 24V 20A fulfills exactly with this premise, offering the industrial robustness characteristic of Victron Energy in a compact and accessible format, designed to control the continuous current flow and prolong the life of your accumulators.

Advanced load algorithm and deep discharge control

Unlike other low-range economic controllers that perform aggressive linear loads, this device uses technology Modulation by pulse width (PWM) Combined with a structured load process in 3 different stages: initial (bulk), Absorption and flotation. This algorithm adapts the voltage supplied to the actual state of the battery bank, achieving an optimal gase recombination and avoiding premature sulfation of lead plates. The regulator manages 14.4V absorption voltages in 12V and 28.8V systems when automatically detects 24V configurations.

Another of the great technical virtues of the bluesolal light of 20A is its output of auxiliary consumption (Loadwith Low voltage disconnection mechanism. The equipment monitors the battery voltage in real time and cuts the supply to the connected consumption if it comes critically until 11.1V (or 22.2V on 24V systems), protecting internal chemistry against destructive deep discharges. The reconnection of this output is automated intelligently by uploading the voltage to 13.1V / 26.2V, or can be manually forced safely at 12.6V / 25.2V. If you need to set your Solar with total firmness on flat surfaces or tilted covers to feed this system, we recommend that you examine our options of Made of high-durability aluminum.

Integrated and direct-sized passive safety

The reliability of this model lies in its complete ecosystem of integrated electronic protections. The controller is designed to proof installation errors or unforeseen faults in the wiring, offering automatic guard on short circuits on the lines, overcurrents on the load and a crucial protection against the polarity investment in both the terminals of the Photovoltaic and batteries. In addition, it incorporates an internal thermal sensor that dynamically adjusts the work voltages according to room temperature, preventing hazardous overheats.

The dimensioning of the modules is very simple and direct. The team is optimized to work natively with solar of 36 cells in 12V installations, or with 72-cell plates (or equivalent series combinations) if an accumulation bank at 24V is available. With extremely reduced dimensions of only 70 x 133 x 34 mm and a net weight of just 150 grams, It is one of the simplest devices to integrate into small electrical pictures or confined spaces. If in the design of your home you are evaluating a system without batteries to save directly on the daylight invoice by direct injection, you can explore the alternatives in our category inverters networking.

Frequently Asked Questions section (FAQ)

1. What kind of Are you suitable for connecting to this 20A PWM regulator?

For a correct operation in 12V battery systems, they must be used Traditional solar of 36 cells (usually plates between 100W and 200W). If your battery bank works at 24V, you must connect of 72 cells or, failing that, match two rows in two (series) Of 36 cells so that the voltage is adequate for the PWM load.

2. What is the secondary load output (LOAD) that the equipment includes the equipment?

It is a specific output to connect consumption in continuous current (such as 12V / 24V bulbs, routers or small water pumps). Its great technical advantage is that it is fully protected by the regulator: If the battery lowers a safe level, the regulator disconnects this output to prevent the batteries from suffering from a deep discharge that breaks them.

3. What happens if by mistake I connect positive and negative cables backwards?

The Victron BLUESOLAR PWM LIGHT has an active protection barrier against reverse polarity both for the connection of the solar boards and for the batteries. If you make an error in the terminal during assembly, the regulator will not burn or suffer internal damage; It simply will not turn on until you scream the position of the cables.

4. Why does the regulator automatically change between absorption and flotation phases?

Because it integrates an intelligent load algorithm in 3 stages. The absorption phase applies a controlled voltage (14.4V / 28.8V) to fill the battery optimally. Once the accumulator reaches its almost total capacity, the regulator lowers the voltage to the flotation range (13.7v / 27.4v) to keep it 100% without heating or evaporating its electrolyte.

5. Is it necessary to acquire an external temperature sensor for this regulator model?

It is not necessary. This model incorporates an internal temperature sensor within its own housing. Thanks to this component, the circuit automatically adjusts the load voltages based on environmental thermal conditions, ensuring that batteries do not suffer overloads in summer or stay short of energy in the winter months.
