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

Advanced maximum power point detection in shaded conditions
Under shadowing conditions, two or more maximum power points may be present on the voltage-power curve. Conventional MPPTs tend to lock on to a local MPP which not necessarily the optimum MPP. SmartSolar's innovative algorithm will always maximize energy recovery by locking on to the optimal MPP.
Outstanding conversion efficiency
No fan. Maximum efficiency in excess of 98%.
PV voltage up to 100 V
The charge controller can charge a battery of lower nominal voltage from a field of PV panels of higher nominal voltage. The controller will automatically adapt to a nominal battery voltage of 12 or 24 V.
Automatic battery voltage recognition
The controller will automatically adjust to a 12 or 24 V system only once. If a different system voltage is required at a later stage, it will have to be changed manually, for example using the Bluetooth application.
Adaptive charging in three steps
The controller is configured for a three-stage charging process: Bulk - Absorption - Float.
Bulk During this stage, the controller delivers as much current as possible to rapidly recharge the batteries.
Absorption When the battery voltage reaches the absorption voltage parameters, the controller switches to constant voltage mode. During shallow battery discharges, the absorption charge time is limited to prevent overcharging. After a deep discharge, the absorption time is automatically increased to ensure the battery is fully recharged. The absorption period also ends when the charging current falls below 2A.
Float During this stage, Float voltage is applied to the battery to keep it in a fully charged state. When the battery voltage drops below the Float voltage for at least 1 minute, a new charge cycle is triggered.

) If higher PV power is connected, the controller will limit the input power
1b) The PV voltage must exceed Vbat + 5 V for the controller to switch on. Then, the minimum PV voltage is Vbat + 1 V 2) A PV array with a higher short-circuit current may damage the controller.
