Wilo-Actun OPTI-MS

Wilo-Actun OPTI-MS – Autonomous, optimised water supply using solar power.

Your advantages
Wilo-Actun OPTI MSH

Wilo-Actun OPTI-MS – Autonomous, optimised water supply using solar power.

Ensuring a reliable water supply in arid and remote regions not connected to the power grid is a challenge. The new solar-powered Wilo-Actun OPTI-MS, provides a solution which is independent of the mains power supply for an effective and reliable water supply.

Recommended services


Your advantages

  • Fully autonomous and cost-efficient water supply by using solar power
  • Easy electrical installation via integrated frequency converter and without needing a parametrisation
  • Optimised water output thanks to high hydraulics and motor efficiencies and dynamic MPPT (Maximum Power Point Tracking – ensures the operation of the solar panel at maximum performance level)
  • System-specific flexibility thanks to a wide range of performances
  • Increased service life and reliability thanks to high-quality materials and an encapsulated motor design
  • Additional operational reliability by using integrated safety devices
  • Easy remote access to operating parameters and settings of the solar submersible pump via the Solar Connect tool in the Wilo-Assistant App
  • Notifications via push messages when operating status changes
Series description
Wilo-Actun OPTI-MS

Design

Multistage submersible pump in tie strap version (MSI) or as progressive cavity pump (MSH) for for vertical or horizontal installation

Application

  • Designed especially for operation with photovoltaic modules
  • For water and drinking water supply from boreholes and rainwater storage tanks
  • Industrial water supply
  • Sprinkling and irrigation
  • Pressure boosting
  • For pumping water without long-fibre and abrasive constituents

Equipment/function

  • Fully submersible, multistage submersible pump:
    • as centrifugal pump in sectional construction (MSI) or
    • as helicoidal rotor pump (MSH)
  • with integrated non-return valve
  • with corrosion-free, encapsulated permanent magnet motor with water-glycol filling
  • Built-in frequency converter
  • Integrated software algorithm MPPT (“Maximum Power Point Tracking”) for applications with solar modules
  • Pre-installed signal cable for direct connection to signal transmitters (e.g. float switches)

Construction

Submersible pump as centrifugal pump in sectional construction (MSI) or as helicoidal rotor pump (MSH) for vertical or horizontal installation.

Hydraulics

A multistage submersible motor centrifugal pump (MSI) with radial impellers in sectional construction or a helicoidal rotor pump (MSH) with helical rotor inside a twin-helix rubber stator. Integrated non-return valve. All parts that come in contact with the fluid are made of corrosion-free materials.

Motor

Single-phase current permanent magnet motor. Sealed and hermetically cast motor, resin-impregnated, with enamel-insulated winding, self-lubricating bearing, with water-glycol filling.

Frequency converter

Hermetically sealed frequency converter for direct operation using alternating current and direct current sources. The integrated software algorithm MPPT (“Maximum Power Point Tracking”) enables the available power to be matched in order to maximise the pumped volume flow (dynamic MPPT).

Safety functions:

  • Overvoltage protection
  • Excess current protection
  • Dry-running protection (via integrated sensor)
  • Temperature monitoring

Cooling

The motor is cooled by the pumped fluid. The motor must always be immersed when operated. The limit values for maximum fluid temperature and minimum flow velocity must be adhered to. Vertical installation is possible with or without cooling jacket. Horizontal installation must be performed in conjunction with a cooling jacket.

Scope of delivery

  • Submersible pump with connection cable (2.5 m)
  • Casting resin cable connector with integrated water level sensor
  • Installation and operating instructions
  • Hydraulics for self-assembly (MSH only), incl. installation instructions and installation accessories
  • Adapter for pressure connection 1½" on 2" (only types OPTI-MSI4.08-..)
