Victron MPPT BT 250/60 250/70 Charge Controller

Victron MPPT BT 250/60 – 250/70 Charge Controller (12V – 24V – 36V – 48V) with MC4 or Screw Connectors

NOTE: Software tool is required to select 36V

Integrated Bluetooth Smart
The wireless solution to configure, monitor, update, and synchronize SmartSolar Charge Controllers.
Ultra-fast Maximum Power Point Tracking (MPPT)

Especially in cloudy weather, when light intensity is constantly changing, an ultra-fast MPPT controller will improve energy harvesting by up to 30% compared to PWM charge controllers and up to 10% compared to slower MPPT controllers.

Advanced Maximum Power Point Detection in case of partial shading
In cases of partial shading, two or more maximum power points (MPP) may exist on the power-voltage curve. Conventional MPPTs tend to lock to a local MPP, which may not be the optimal MPP. The innovative SmartSolar algorithm will always maximize energy harvesting by locking onto the optimal MPP.

Ultra-high conversion efficiency
No cooling fan. Maximum efficiency exceeds 98%.

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).

Very high electronic protection:

• Over-temperature protection and power derating when temperature is high.
• PV short circuit and PV reverse polarity protection.
• PV reverse current protection

Internal temperature sensor
Compensates absorption and float charge voltages for temperature.

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 BlueSolar charge controllers.

Synchronized parallel charging with Bluetooth
Up to 10 units can be synchronized with Bluetooth.

Fully discharged battery recovery function
Will start charging even if the battery has been discharged to zero volts. Will reconnect to a fully discharged Li-ion battery with integrated disconnect function.

VE.Direct
For wired data connection to a Color Control GX or other GX devices, PC or other devices.

Remote on-off
To connect for example to a VE.BUS BMS.

Programmable relay
Can be programmed to trigger 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.
