Victron BlueSolar MPPT 100/50

In a nutshell

Medium-sized MPPT solar charge controller, 100 V and 50 A, for 12 or 24 V batteries. It uses up to 1,400 W of panels at 24 V.

Ideal for medium-sized 12 or 24 V systems: a shed, a vehicle, a boat or a small house.

What the two numbers of an MPPT charge controller mean

• The input voltage is the maximum combined voltage of the panels connected in series. Keep in mind the Voc (open-circuit voltage) of your panels and leave a margin: on cool mornings it rises a little.
• The amps are the maximum current the controller delivers to the battery. Multiplied by the battery voltage, this current gives the panel power it can use.
• That is why the same controller delivers twice as much at 24 V as at 12 V.
• It works only with 12 or 24 V batteries; for a 48 V system you need a controller that accepts 48 V.
• If more panels are connected than it can handle, the controller simply does not use the excess (excess power does not damage it). But never exceed the input voltage: that does break it.

About this model (100 V · 50 A)

• For example, if a panel has 50.6 V open-circuit, only one fits in series: two add up to 101 V, more than the 100 V it accepts.
• Usable power: 700 W at 12 V · 1,400 W at 24 V.
• Panels and battery are connected with screw terminals. Efficiency 98 %.
• It does not include built-in Bluetooth: it is configured and monitored through its VE.Direct port, with the VictronConnect app via a VE.Direct Bluetooth Smart dongle or a VE.Direct to USB cable.
