Ultra-fast Maximum Power Point Tracking (MPPT)
Especially in 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 PWM charge controllers 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 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 (see the software page on our website), and eight pre-programmed algorithms, selectable with a rotary switch (see the 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.
Internal temperature sensor
Compensates absorption and float charge voltage for temperature.
Bluetooth Smart built-in: dongle not needed
The wireless solution to set-up, monitor and update the controller using Apple and Android smartphones, tablets or other devices.
For a wired data connection to a Color Control GX, other GX products, PC or other devices
To connect for example to a VE.BUS BMS.
Can be programmed (a.o. with a smartphone) to trip on an alarm, or other events.
Optional: pluggable LCD display
Remove the seal that protects the plug on the front of the controller, and plug-in the display.

|1a) If more PV power is connected, the controller will limit input power to the stated maximum.
1b) The PV voltage must exceed Vbat + 5V for the controller to start.
Thereafter the minimum PV voltage is Vbat + 1V.
2) A PV array with a higher short circuit current may damage the controller.
3) MC4 models: several splitter pairs may be needed to parallel the strings of solar panels.
Maximum current per MC4 connector: 30A (the MC4 connectors are parallel connected to one MPPT tracker)
