Victron Energy Smart Battery Sense for MPPT Solar Chargers Long Transmission Range 10-meters  SBS050150200

Our range of solar chargers fitted with a VE.Direct port were lacking battery voltage and temperature charge compensation. Not now!

Also, today we announce the launch of Victron Energy’s Smart Battery Sense – a product to compliment the new feature. New, simple, smart …and wireless.

Why do we need voltage and temperature sensing?

    Improves solar yield
    Maximises battery capacity
    Increases battery life

AGM & Gel (lead acid) batteries use charging algorithms based on a standardised temperature of 25°C. However – when they’re cold these batteries need a higher charge-voltage …and a lower charge-voltage when they’re hot. So, optimally, we should modify the charge-voltage by, typically, -16.2mV/°C.

Also there can be a difference between the voltage measured at an MPPT solar charger’s terminals, and that measured at the battery terminals. For optimum charging that discrepancy needs to be taken into account, too. The Victron Toolkit app demonstrates how this voltage drop is brought about as a consequence of cable length and gauge; together with voltage and current variations.

Good news though: Our MPPT Solar Chargers and accessories can figure all this out – so you don’t have to!
Voltage and Temperature data – transmitted wirelessly to your MPPT

The Smart Battery Sense is a wireless battery voltage and temperature sensor for Victron MPPT Solar Chargers.


    Simple installation – attach the unit to any battery by its self-adhesive tape.
    Protected by an inline fuse.
    Voltage and temperature data is transmitted wirelessly to the Solar Charger.
    Monitor & configure the unit from your smart phone – via our free-to-use VictronConnect app.
    Transmitted data can be networked to one, two – or more solar chargers connected to the same battery battery bank.
    Works for 12, 24 and 48 volt battery banks
    Works for both Lithium and Lead battery banks
    Compatible with most BlueSolar and SmartSolar MPPT charger models: see VE.Smart Networking for compatible-models list.
