Automatic voltage adjustment
MIDA Solar is equipped with an internal “boost” circuit able to increase the voltage coming from solar panels. In this way the sizing of the photovoltaic system is independent of the pump’s nominal voltage and only proportional to its power. This implies a significant saving in the number of the solar panels, compared to systems without boost.
Example:
Pump power: 0,75 kW
Motor’s nominal voltage: 3×230 VAC
Recommended photovoltaic system power: 1250 W
Without boost
In order to allow the pump to reach the maximum frequency (maximum speed) it is necessary to guarantee at least 320 VDC input thus it is necessary to install 11 panels 250 Wp, totally 2750 Wp.
With boost
Thanks to the voltage boost integrated in MIDA Solar, only 5 panels 25O Wp are needed, with a consequent saving of 6 panels.
* The example considers panels 250 Wp, 30 Vmp, 37 Voc.
