  • Page 3: Mida Solar Introduction

    1. MIDA Solar Introduction MIDA Solar inverters come to power traditional pumping systems using photovoltaic energy. In this way it’s possible to convert old systems in renewable energy installations or to use the same AC pumps in the creation of independent, cost-saving and environmentally sustainable water systems. MIDA Solar is able to convert DC voltage coming from photovoltaic panels into AC voltage for powering any pump.

    2. Safety Instructions The manufacturer strongly suggests carefully reading this operation manual before using and installing its products Any operation (installation, maintenance and repair) must be carried out by trained, skilled, and qualified personnel. Failure to observe and follow the instructions in this manual may result in dangerous and potentially lethal electric shock. Pay attention to all standard safety and accident prevention regulations The device must be connected to power supply via a switch to ensure the complete disconnection from the network before any operation on the MIDA...

It is recommended to use only volt free contacts. Digital inputs can be configured as Normally Open or Normally Closed by software.

  • Page 11: Protections

    5.1 Protections The protections required upstream each MIDA Solar depends on the type of installation, and local regulations. Safety protections on both AC (in MP models) and DC side must be used. For DC side we recommend to use 1000 VDC circuit breaker and, if possible, 1000 VDC surge protection. For AC side we recommend to use overload protection with the characteristic curve of type C and type B circuit breaker, sensitive to both AC and DC current.

    6.1.3 FOC motor control Introduction FOC (Field Oriented Control) motor control implemented in FOC-ready inverters provides the following advantages compared to traditional control:  Optimal control of the current at each work point.  Quick and precise speed adjustment.  Lower energy consumption.
  • Page 24 If the calibration process is not successful, it is necessary to check:  The connections between the inverter and the load (including any motor filters in between).  The rated voltage, frequency and current values set. The motor cannot be started until the calibration process has been completed. If the calibration process cannot be completed, it is possible to manually enter the parameters or stator resistance (Rs) and stator inductance (Ls) in the motor parameters menu (default password 002).
