Victron BlueSolar PWM-Light 48V-20A

Original price was: $130.00.Current price is: $118.18. (inc. GST)

The Victron BlueSolar PWM-Light 48V-20A is a solar charge controller that regulates the charging of 48V DC solar panels. This charge controller uses pulse width modulation (PWM) technology to provide efficient and reliable charging of batteries, helping to extend battery life. It’s designed for use in off-grid solar systems and is suitable for applications such as cabins, RVs, and boats. The Victron BlueSolar PWM-Light 48V-20A features an easy-to-read LCD display that provides real-time information on battery voltage, charging current, and charging status. It also has built-in protection features to prevent damage to the battery and solar panels, making it a reliable and safe choice for your solar system. The 20A capacity of this charge controller allows for larger systems and more powerful solar panels to be used.

Victron Bluesolar light PWM solar controller:

Victron's range of  PWM and MPPT charge controllers are both widely used to charge batteries with solar power.

The PWM controller is in essence a switch that connects a solar array to the battery. The result is that the voltage of the array will be pulled down to near that of the battery.

A PWM controller is not a DC to DC transformer. The PWM controller is a switch which connects the solar panel to the battery. When the switch is closed, the panel and the battery will be at nearly the same voltage. Assuming a discharged battery the initial charge voltage will be around 52 V, and assuming a voltage loss of 0,5 V over the cabling plus controller, the panel will be at Vpwm = 52,5 V.

The voltage will slowly increase with increasing state of charge of the battery. When absorption voltage is reached the PWM controller will start to disconnect and reconnect the panel to prevent overcharge (hence the name: Pulse Width Modulated controller).

Features:

-Load output with low battery voltage disconnect function.

-Lighting control function, one timer only.

-Seven segment display for quick and easy setting of the load output functionality, including timer setting.

-Three stage battery charging (bulk, absorption, float), not programmable.

-Load output protected against over load and short circuit.

-Protected against reverse polarity connection of the solar array and/or battery.
