20A SOLAR CHARGE CONTROLLER FOR SOLAR PANELS UP TO 290W (12V) / 580W (24V) / 1160W (48V) UP TO 100V (BLUETOOTH INBUILT)
 
This Victron 100V 20A MPPT controller comes from the intelligent SmartSolar range, which uses the latest ultrafast MPPT technology to maximise energy harvest whilst maintaining optimal battery health. This SmartSolar MPPT controller uniquely features built-in Bluetooth, to allow remote system monitoring via any Bluetooth enabled device, in addition to an intelligent BatteryLife function .
Ultrafast MPPT Technology:
This 20A MPPT solar charge controller is designed to deliver the highest possible energy yield in the shortest amount of time. This is achieved through the use of high speed Maximum Power Point Tracking technology, which tracks the maximum power voltage point of the solar panels as it varies depending on sunlight exposure and temperature. 
This technology enables the controller to produce up to 30% greater energy yield than PWM controllers and as much as 10% more power than slower MPPT controllers. This advanced technology allows the controller to perform extremely well in low-light or cloudy conditions, as the controller consistently strives to extract the maximum available power from the solar array.
Inbuilt safety protection:
Fully equipped with an extensive range of safety features, this controller offers complete protection against potential hazards such as battery reverse polarity, load short circuit, low-voltage load disconnect and battery overheating - monitored via the internal temperature sensor. The controller also has self-diagnostic capability and highlights any system errors using sophisticated fault-targeting technology. These are signalled via the high intensity LED indicators.  
Intelligent 'BatteryLife' function:
To prevent complete discharge of the battery and avoid potentially permanent damage, this controller is equipped with the Victron BatteryLife function; a state-of-the-art feature designed to extend the lifetime of the battery by monitoring and controlling the output of excessive loads. Using an intelligent algorithm, the controller will continuously monitor the battery state of charge, and if required (e.g. during periods of poor weather), will gradually adjust the load disconnect threshold until a full 100% recharge is con
