Solar Charger Victron BlueSolar MPPT 75/15 12-24V 15A

Ultrafast 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 BlueSolar algorithm will always maximize energy harvest by locking to the optimum MPP.

Outstanding conversion efficiency
No cooling fan. Maximum efficiency exceeds 98%. Full output current up to 40°C (104°F).

Flexible charge algorithm
Fully programmable charge algorithm (see the software page on our website), and eight preprogrammed algorithms, selectable with a rotary switch (see Manual for details).

Extensive 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 voltage for temperature.

Real-time data display options
- Color Control GX or other GX devices:
see the Venus documents on our website.
- A smartphone or other Bluetooth-enabled device:
VE.Direct Bluetooth Smart dongle needed.

Extras:

Three Stage Charging

• Stage One - Bulk or Boost – As much current as possible is delivered in order to rapidly recharge the batteries to about 80%.
• Stage Two - Absorption – When the battery reaches its final charging voltage, known as its absorption voltage the charge allows the current to taper off as the battery nears a full charge.
• Stage Three - Float – At this stage float voltage is applied which is enough to retain a full charge but controlled to prevent overcharging.
