Fully autonomous and economical water supply through the use of solar energy
Simple electrical installation with integrated frequency converter without parameter input
Optimised water flow due to high hydraulic and motor efficiency and dynamic MPPT (Maximum Power Point Tracking - ensures solar panel operation at maximum power)
Plant configuration-oriented flexibility due to a wide output range
Superior longevity and reliability due to high quality materials and encapsulated motor construction
Additional operational reliability due to integrated safety devices
In arid, remote and off-grid regions, an uninterrupted water supply is a challenge. The new Wilo-Actun OPTI-MS, which is powered by solar energy, ensures an efficient and reliable water supply even in areas without power.

Submersible pump as submersible centrifugal pump in close-coupled design (QSI) or as eccentric screw pump (QSH) for vertical or horizontal installation.
Hydraulic section
Multistage submersible centrifugal pump (QSI) with radial impellers in sectional design or as eccentric screw pump (QSH) with eccentric screw in double volute rubber stator. Built-in check valve. All parts in contact with the pumped liquid are made of corrosion-resistant materials.
Electric motor
AC type permanent magnet motor. Leak proof encapsulated stator with enameled windings, self-lubricating bearings, water-glycol mixture filling.
Frequency converter
Sealed frequency converter for direct operation with DC power supplies. Integrated software algorithm MPPT (Maximum Power Point Tracking) provides adaptation to available power to maximize water supply (dynamic MPPT).
Safety features:
Cooling
The electric motor is cooled by the pumped liquid. The electric motor may only be operated in immersed state. The maximum temperature limits for the pumped liquid and the minimum flow speed must be observed. Vertical installation can be carried out with or without a cooling jacket - at the customer's choice. Horizontal installation is done with a cooling jacket.
