Description

Victron BlueSolar PWM-Pro 12/24V-20A

The Victron BlueSolar PWM-Pro 12/24V-20A is a reliable solar charge controller that automatically detects your battery voltage (12V or 24V) and charges via a three-stage algorithm (bulk, absorption, float). This maximizes battery life and ensures your system operates efficiently. Perfect for RVs, boats, and off-grid cabins. Now at $42, that's 50% off the original $84 price, plus extra 10% off with code SAVE10.

Specifications

Brand: Victron Energy
Model: BlueSolar PWM-Pro 12/24V-20A
Product Type: Solar Charge Controller (PWM)
Max PV Voltage: 100V
Max PV Power: 250W (12V) / 500W (24V)
Rated Current: 20A
System Voltage: Auto-detect 12V/24V
Charging: 3-stage (bulk, absorption, float)
Features: Load output with low voltage disconnect, LED indicators

Compatibility & Use

This controller works with 12V or 24V panels and batteries. For a 12V system, you can use up to 250W of solar; for 24V, up to 500W. It automatically detects system voltage, but ensure your solar panel's voltage is within the input range (max 100V). It is not recommended to use a 24V panel with a 12V battery as it will waste energy and may not charge properly; a PWM controller works best with panels matching the battery voltage.

Value & Savings

At $42, this is a 50% discount from $84. Use code SAVE10 at checkout for an additional 10% off, making it $37.80. Free shipping on orders over $45. A great entry-level controller for small solar setups.

Frequently Asked Questions

What size solar panel can I use with a Victron BlueSolar PWM-Pro 20?

For a 12V system, the maximum recommended PV power is 250W. For a 24V system, it is 500W. The maximum PV voltage is 100V. Choose a panel that matches these limits and your system voltage for optimal performance.

Can I use a 24V solar panel with a 12V battery on a PWM-Pro 20?

Technically it will work, but it is not recommended because a 24V panel produces a higher voltage than a 12V battery needs, and a PWM controller will simply convert the excess into heat, wasting energy and potentially reducing efficiency. A better option is to use a 12V panel or an MPPT controller if you must use a higher voltage panel.

How many watts can a 20A PWM charge controller handle?

For a 12V system: 20A * 14.4V = 288W, but Victron recommends a maximum of 250W. For a 24V system: 20A * 28.8V = 576W, but the recommended max is 500W. Always consider the controller's current rating and battery voltage.

What is the max PV voltage for the BlueSolar PWM-Pro 20?

The maximum PV voltage is 100V per the manufacturer's specifications. Be sure to stay within this limit to avoid damaging the controller.

Where can I buy this at the best price?

Great budget controller

It handles my RV panels well. The auto-detect for 12/24V is nice. I've seen better efficiency in MPPT, but for the price, it's a winner.

Simple and effective

Plugged it in, connected the panels, and it's been charging my batteries without fuss. The display is clear. 50% off made it even better.

Works, but terminal springs

It's okay, but the terminal springs for wires are a bit weak. You need to ensure wires are firmly inserted. Performance is fine, but I expect more robust build.
