THE INVERTER FOR SOLAR PUMPING APPLICATIONS

VASCO Solar - VAriable Speed COntroller INVERTERS ARE DESIGNED TO POWER TRADITIONAL PUMPING SYSTEMS USING SOLAR ENERGY. THIS WAY IT IS POSSIBLE TO CONVERT OLD SYSTEMS INTO RENEWABLE ENERGY INSTALLATIONS OR TO USE THE SAME AC PUMPS TO CREATE INDEPENDENT, COST-SAVING AND ENVIRONMENTALLY SUSTAINABLE WATER SYSTEMS. The device is able to convert DC voltage coming from solar panels into AC voltage for powering any pump driven by a three-phase motor. Pump speed is constantly adapted to available solar irradiation thus maximising the amount of pumped water and making possible operation even in conditions...

VASCO Solar - VAriable Speed COntroller CAN BE USED WITH ANY TYPE OF TRADITIONAL AC PUMP, THEREBY OFFERING MAXIMUM FLEXIBILITY IN SEVERAL AREAS OF APPLICATION. When using surface pumps, device 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, it is possible to fill tanks for watering livestock or simply irrigate lawns or crops. NEW KEYBOARD OLED graphic display with extended operating temperature range and wide viewing angle. Digital text rotation based on installation position. LED indication for standby,...

THE INVERTER, IN MP (MULTIPOWER) VERSION, CAN BE POWERED IN DC BY SOLAR PANELS OR IN AC BY NETWORK OR GENERATOR TO ENSURE THE FUNCTIONING OF THE PUMP AT ANY HOUR OF THE DAY. 5. Buffer tank (optional) This controls the peaks of water demand using AC input to avoid the oversizing of the photovoltaic system. HMA accessory, used in combination with 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: ■ achievement of the requested daily range ■ remote control trough digital command MULTIPOWER HYBRID...

MPPT: ALWAYS THE MAXIMUM POWER AVAILABLE 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. 6 A 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....

To maximize the efficiency and reliability of a solar pumping system, instead of using a single high-power pump, it is possible to divide it into two or more pumps in parallel, each controlled by variable-speed inverters and powered by the same photovoltaic system. When the system consists of a single pump, in conditions of low irradiation, the pump is often stopped as the photovoltaic power is not sufficient to ensure its operation. On the other hand, when the system is divided into multiple lower-power pumps, even in conditions of low irradiation, at least one or more pumps continue to operate,...

MONITORING PARAMETERS The inverter is equipped with a display to monitor key electrical parameters like input voltage, power, current and motor power factor. It is also possible to connect a pressure or flow sensor to monitor performance levels. In the diagnosis menu are recorded inverter and motor hours, operation statistics, and the last eight alarms occurred. The programming menus are password-protected to prevent unwanted tampering. COMPLETE PUMP PROTECTION The device is able to protect the pump against overload and dry running. Dry running protection is performed by monitoring the motor’s...

Thanks to the Nastec NOW app it is possible to communicate with all Nastec SMART Bluetooth® devices in order to: ■ Monitor multiple operating parameters simultaneously on the wide, high-definition colour screen of your smartphone or tablet. ■ Develop programs, save them in the archive, copy them to other devices and share them among multiple users. ■ Get energy consumption statistics and check the alarm log. ■ Remotely control a Nastec device via Wi-Fi or GSM by tethering to a nearby smartphone. ■ Create reports with the possibility of adding notes and images, and email or store them in the digital...

PREDICTIVE ANALYSIS AND REMOTE CONTROL Through predictive analysis conducted by the device during operation, it is possible to intervene before a problem occurs, minimizing intervention and repair costs. If the device is connected to the internet, warning or alarm notifications can be sent via email to the relevant users. To do so, a quick configuration is required through the remo.nastec.eu portal. remo.nastec.eu REMO, the revolutionary Nastec system for remote controlling devices. To implement the REMO control system you will need to: Install an Android or iOS smartphone nearby Nastec device...

The pumping system must be designed taking into account the required daily flow rate, total head and the installation site. In particular, the choice of the pump must be made considering the average daily solar irradiation. Once the appropriate pump has been identified, it is necessary to know: ■ Rated pump power (P2) ■ Electrical motor power (P1). P1 can be derived by dividing P2 by motor efficiency. ■ Rated motor current ■ Rated motor voltage 3 x 230 VAC or The inverter model to be used is determined by considering voltage and rated motor current. To ensure maximum performance, the solar system...
