Victron Energy BlueSolar PWM Pro Charge Controller 12/24V 5A

Product Description The Victron Energy BlueSolar PWM-Pro 12/24V 5A is designed for smaller solar charging systems where you want more control than a basic PWM controller. It’s ready to run on default settings, but the big win is flexibility — you can programme both the charging behaviour and the load/lighting functions to match the battery type, usage pattern, and what you want the system to do overnight. It automatically detects 12 V or 24 V battery systems, charges using a proper three-stage profile, and includes a load output with low-voltage disconnect to help protect the battery from over-discharge. It also supports more advanced features such as integrated battery monitoring (when used with the appropriate remote panel) and an optional external temperature sensor for better charging accuracy. A great choice for small off-grid cabins, sheds, remote comms boxes, or solar lighting systems that need reliable charging and smarter load control. Key Features Fully programmable PWM controller – Adjustable charging and load behaviour to suit different batteries and use cases. 12 V / 24 V auto-detection – Automatically recognises system voltage for straightforward installs. Three-stage charging – Bulk, absorption, float charging, fully programmable. Lighting control built in – Day/night and timer options, fully programmable for solar lighting or automation. Load output with battery protection – Low-voltage disconnect plus manual load control (default behaviour supports battery protection). Protection built in – Load output protected against overload and short circuit, plus reverse polarity protection for PV and battery.
