Victron Energy SmartSolar MPPT 250/70 Charge Controller
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
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
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 manual for details).
Extensive electronic protection
Over-temperature protection and power derating when temperature is
PV short circuit and PV reverse polarity protection.
PV reverse current protection.
Internal temperature sensor
Compensates absorption and float charge voltage
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 panel, Venus GX, 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.
