MPPT controller Victron SmartSolar 100/30 - 100/50 12/24V

Ultra-fast maximum power point tracking (MPPT).

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 (pulse-width modulation) 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.

Flexible charging algorithm

Fully programmable charging algorithm (see the Software section of our website) and eight pre-programmed algorithms selectable with a rotary switch (see manual for details).

Extended electronic protection

Protection against overheating and power reduction in case of high temperature.

Internal temperature sensor

Compensates Float and Absorption charge voltages as a function of temperature.

VE.Direct

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

Remote on/off

For connection to a VE.BUS BMS, for example.

Programmable relay

Can be programmed (e.g. with a Smartphone) to trigger an alarm, or other events.
