Victron Energy BlueSolar MPPT Solar Charge Controller - MPPT Charge Controller for Solar Panels - 75V 10 amp 12/24-Volt

Have tried a few other types of controllers for solar charging to caravan and after a bit of faffing about and not gaining sufficient charge to off grid sites went for one of these. There are different variations to match your needs but these bad boys rinse every particle of energy being produced and tuck it into your battery for later use. The Bluetooth has its benefits and give you history of charge/solar panel captivation and +- battery charge levels. Its a bit of overkill but did buy a second for a spring project for the shed.

Bluetooth app works well. solid unit. works to specification

Why did you choose this product over others?: Quality

Does exactly what it suppose to. No issues with this controller.

Don’t buy this. It has no Bluetooth , despite the name. Very misleading and the units are in every other way identical. Also very misleading is the claim it has Bluetooth, when in fact you need to buy a £32 dongle. Get the SmartSolar version instead. Same price, comes with Bluetooth. I didn’t take it out of its box until past the 30 days return window , otherwise I would have swapped.

Using this on two 100 watt panels in series in the summer and parallel in the winter. My only criticism is Victron only include presets for the batteries they make so no flooded lead acid.

The controller charges, but we don't know anything more without a Bluetooth device that can be purchased for almost the same price as the controller. For that price, it's a bit excessive not to have visibility into the charging power and the battery charge level.

Good
