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%.

PV voltage up to 100V

The charge controller is able to charge a lower nominal-voltage battery from a higher nominal voltage PV array. The controller will automatically adjust to a 12 or 24V nominal battery voltage.

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 high. PV short circuit and PV reverse polarity protection. PV reverse current protection.

Internal temperature sensor

Compensates absorption and float charge voltage for temperature.

Adaptive three step charging

The Controller is configured for a three step charging process: Bulk – Absorption – Float.

Bulk
During this stage the controller delivers as much charge current as possible to rapidly recharge the batteries.

Absorption
When the battery voltage reaches the absorption voltage setting, the controller switches to constant voltage mode. When only shallow discharges occur the absorption time is kept short in order to prevent overcharging of the battery. After a deep discharge the absorption time is automatically increased to make sure that the battery is completely recharged. Additionally, the absorption period is also ended when the charge current decreases to less than 2A.

Float
During this stage, float voltage is applied to the battery to maintain it in a fully charged state. When the battery voltage drops below float voltage during at least 1 minute a new charge cycle will be triggered.

VE.Direct

For a wired data connection to a Color Control panel, PC or other devices

Remote on-off

To connect for example to a VE.BUS BMS.

Automatic battery voltage recognition

The controller will automatically adjust itself to a 12V or a 24V system one time only. If a different system voltage is required at a later stage, it must be changed manually, for example with the Bluetooth app.
