Features & Benefits
Ultra-fast Maximum Power Point Tracking (MPPT)
Especially in the case of a clouded sky, when light intensity is changing continuously, an ultra-fast MPPT controller will improve energy harvest by up to 30 % compared to the PWM charge controller and by up to 10 % compared to slower MPPT controllers.
Advanced Maximum Power Point Detection in case of partial shading conditions
If partial shading occurs, two or more maximum power (MPP) points may be present on the power-voltage curve. Conventional MPPTs tend to lock to a local MPP, which may not be the optimum MPP. The innovative SmartSolar algorithm will always maximize energy harvest by locking to the optimum MPP.
Outstanding conversion efficiency
No cooling fan. Maximum efficiency exceeds 99 %.
Flexible charge algorithm
Fully programmable charge algorithm, and eight pre-programmed algorithms, selectable with a rotary switch (see manual for details).
Extensive electronic protection
Over-temperature protection and power derating when the temperature is high. PV short circuit and PV reverse polarity protection. PV reverse current protection.
Bluetooth Smart built-in
The wireless solution to set up, monitor, update and synchronise SmartSolar Charge Controllers.
Internal temperature sensor and optional external battery voltage, temperature and current sensing via Bluetooth
A Smart Battery Sense, a BMV-712 Smart Battery Monitor or a SmartShunt can be used to communicate battery voltage and temperature (and current, in case of a BMV 712 or a SmartShunt) to one or more SmartSolar Charge Controllers.
Synchronized parallel charging with VE.Can or Bluetooth
Up to 25 units can be synchronized with VE.Can, and up to 10 units with Bluetooth.
Fully discharged battery recovery function
Will initiate charging even if the battery has been discharged to zero volts. Will reconnect to a fully discharged Li-ion battery with an integrated disconnect function.
VE.Can: the multiple controller solution
Up to 25 units can be synchronised with VE.Can.
Remote on-off
To connect for example to a VE.BUS BMaS.
Programmable relay
Can be programmed to trip on an alarm or other events.
Optional: SmartSolar pluggable LCD display
Simply remove the rubber seal that protects the plug on the front of the controller, and plug in the display.
