1a) If more PV power is connected, the controller will limit input power to the stated maximum. 1b) PV voltage must exceed Vbat + 5V for the controller to start. Thereafter minimum PV voltage is Vbat + 1V 2) MC4 models: several splitter pairs will be needed to parallel the strings of solar panels
Ultra-fast Maximum Power Point Tracking (MPPT)
Especially in case of a clouded sky, when light intensity is changing continuously, an ultra fast MPP controller will improve energy harvest by up to 30% compared to PWM charge controllers and by u 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-voltag curve. Conventional MPPT’s 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.
