PWM loading regulator Victron BlueBlimsolar Light 30A 12V / 24V

Victron BlueSolar PWM LIGHT 30A: Safe current driving, load algorithm in 3 stages and cell protection

The development of self-consumption projects isolated from small power or mobile applications such as field booths, external lighting systems, camperized vans or nautical signage, requires robust controllers that optimize economic investment without compromising the operational security of the Accumulators The regulator Victron BlueBlinking PWM LIGHT 12V / 24V 30A it offers the contrasted electronic reliability of the signature Victron Energy in a simplified chassis, becoming the perfect component to rule small-scale solar fields efficiently.

Advanced care of accumulators and control against deep discharge

Unlike the low quality linear controllers that thermally stress the chemical components, this device uses the technology of modulation by pulse width (PWM) ruled by a 3-stage intelligent algorithm: initial (bulk), Absorption and flotation. This adaptive load cycle drastically reduces the sulfation of lead plates and evaporation of the electrolyte, adjusting the voltages at 14.4V or 28.8V in the absorption phase depending on whether the system identifies in shape Automatic 12V or 24V batteries, respectively.

The team provides a fundamental technical value through its secondary consumption output (Load), endowed with a cutting mechanism by low voltage. This function monitors the load state and suspends the supply of the connected auxiliary consumptions if the accumulator voltage critically falls at 24V (or 22.2V in 24V networks), preserving the life of the battery when avoiding deaths premature overdownload. The restoration of the current to consumption is carried out automatically upon reaching 13.1V / 26.2V, or can be forced by a secure manual reconnection when the system registers 12.6v / 25.2V.

Redundant electronic security and direct technical sizing

The operating solidity of the bluesolal Light of 30A resides in the integration of automated passive safety barriers. Interior electronics is fully armored versus commonly contingencies during assembly or exploitation of the plant, such as short circuits in the wiring, overcurrents due to excess demand at the auxiliary output and polarity investment in the connections of the lines of or batteries. Likewise, the internal thermal sensor performs a continuous mathematical compensation of work voltages based on environmental climatic fluctuations.

Photovoltaic sizing is direct and lacks design complications: it is optimized to process the energy of solar of 36 cells for configurations with 12V accumulators, or modules of 72 cells (or equivalent series) if it is worked in ranges of 24V, taking full advantage of its rated capacity. Presents an extremely compact volumetry of 70 x 133 x 34 mm and an ultralight weight of solo 200 grams, allowing its installation in confined locations or reduced splicing boxes. If the approach of your residential project is focused on direct daytime savings without batteries through surplus compensation, we advise you to examine the alternatives in our section of inverters networking.

FAQ Section (Frequently Asked Questions)

1. What types of can I associate with this 30A PWM regulator?

For an installation with 12V batteries, you must use standard of 36 cells (commonly models of up to 200W). If your storage bench works at 24V, you must connect of 72 cells or, failing that, wire in serial pairs (positive with negative) two identical of 36 cells to raise the voltage to the optimal range of the PWM modulation.

2. What is the purpose of the "Load" output with additional terminals that includes the chassis?

It is a secondary feeding channel designed to directly connect consumption that work in direct current (for example, LED luminaires, communication routers or small water pumps at 12V or 24V). Its technical advantage is that it has the active protection of the regulator, cutting the energy step if the batteries fall from a safe level.

3. What happens to the regulator if you confuse the cables and connect them with the inverted polarity?

Absolutely nothing. The Victron BlueBlue PWM LIGHT Integrates Diodes and electronic barriers against reverse polarity both in photovoltaic input and the battery bank connection. If you make an error in the terminal during the assembly, the device will simply do not turn on, protect your circuits until you restore the correct position of the wiring.

4. Why is the process of sequential load in 3 phases of this equipment beneficial?

Because it optimizes accumulation and protects internal chemistry. The initial phase injects all the current available until recovery the bulk of capacity; The absorption phase sets a controlled voltage (14.4v / 28.8V) to consolidate the total filling; and the flotation phase reduces the tension (13.7v / 27.4v) to keep the battery charged 100% indefinitely without causing evaporation of electrolyte or overheating.

5. Is it necessary to install an external thermal sensor in the battery bank for this model?

It is not necessary to add additional accessories. This model houses a factory calibrated internal temperature sensor within its own structure. Thanks to this element, the regulator autonomously readjust the charging voltages based on the room temperature of the machine room, ensuring that accumulators do not suffer from critical overloads in summer.
