When using surface pumps, MIDA Solar can be used for an irrigation system drawing water from a nearby water supply, or powering a pool pump at no cost.
When using submersible pumps, MIDA Solar can fill tanks for watering livestock or simply irrigate lawns or crops.
To ensure the functioning of the pump at any hour of the day. This controls the peaks of water demand using AC input to avoid the oversizing of the photovoltaic system.
HMA accessory, MIDA Solar, in MP (MultiPower) version, can be powered in DC by solar panels or in AC by network or generator used in combination with MIDA Solar MP models, manages independently the exchange from a source of energy to another on the basis of several options that can be select by the user:
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
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.
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.
Based on the varying conditions of solar irradiation and temperature, MPPT (Maximum Power Point Tracking) maximises the electrical power drawn from the panels and therefore the amount of water pumped. The greater the solar irradiation the faster the pump’s rotation speed, and consequently water flow increases.
When solar irradiation decreases (due to clouds or the different times of day), the pump reduces frequency and therefore the flow, but it continues to provide water until the irradiation falls below a minimum level necessary to ensure operation.
