VSP solar pumps

Product catalog summary
Overview: Nastec's VSP systems are designed for a wide range of solar-powered pumping applications. These systems combine VASCO Solar inverters with stainless steel submersible pumps, offering reliability and performance across various water demands.
Specifications: The VSP systems feature variable speed control to adapt pump speed to solar irradiation, maximizing water output even in low sunlight. The system includes complete pump protection against surges, overloads, and dry running, with components made from corrosion-resistant materials like AISI 304 stainless steel.
Inverter Features: The inverter converts DC voltage from solar panels to AC voltage for three-phase motor pumps. It uses MPPT technology to optimize power extraction from solar panels, adjusting pump speed based on solar conditions.
Protection and Connectivity: The system protects against overload and dry running without probes, and includes surge and overheating protection. Connectivity options include alarms, motor signals, sensors, and Modbus RTU, with remote control via Bluetooth and the Nastec NOW app.
Monitoring and User Experience: Users can monitor parameters on a smartphone or tablet, access energy statistics, and manage alarms. The system allows program development, sharing, and remote control via Wi-Fi or GSM.
Pump and Motor Specifications: The pumps are available in sizes from 4” to 10”, with stainless steel impellers and diffusers. They support a maximum sand content of 50 g/m3 and water temperatures up to 30°C. Motors are available in encapsulated or rewindable versions, with insulation class F and IP68 protection.
Performance Range: The VSP pumps offer 14 hydraulic stages with flows from 2 to 215 m3/h, adaptable to various head requirements. The Nastec Solar Calculator assists in selecting the appropriate pump configuration.
Technical Specifications: The VASCO Solar inverters operate in ambient temperatures from -10 to 50°C, with a protection degree of IP65 or IP54. They support various input and output configurations, including digital and analog inputs, and are compatible with Bluetooth SMART technology.

VSP solar pumps-3

This inverter 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 of low sunlight. The device also offers complete pump protection against surges, overloads and dry running. It is built entirely of aluminium to ensure maximum cooling and durability. Other metal parts are made using AISI 304 stainless steel and therefore resistant to corrosion. Two independent external...
