Page 3: Vasco Solar Introduction
1. VASCO Solar Introduction VASCO Solar 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. -

Page 14: Pressure Sensor
7.1.2 Pressure sensor VASCO Solar requires a pressure sensor with a linear output signal within the range 4 – 20 mA. The pressure transducer can be powered by any range of DC Voltage which includes the value 15 V dc. VASCO Solar accepts the signal of a second pressure sensor in order to: ... -
Page 15: Initial Configuration
8.2 Initial configuration When VASCO Solar is switched on for the first time, the initial setting menu is displayed for the initial setting of parameters to configure pump and system characteristics. If the initial setting procedure is not completed properly, it is impossible to run the pump. Initial setting procedure can be repeated if necessary. -
