Aside from the operating voltage range, another main parameter is the start-up voltage. It is the lowest acceptable voltage that is needed for the inverter to kick on. Each inverter has a minimum input voltage value that cannot trigger the inverter to operate if the PV voltage is lower than what is listed in the specification sheet.
Safety and Compliance: EN 50524 mandates that inverters’ datasheets and nameplates include safety ratings, such as electrical isolation requirements and protection standards, ensuring that the inverter complies with European safety norms.
These standards, developed by organizations such as CENELEC (European Committee for Electrotechnical Standardization), are designed to provide consistency in the design, operation, and testing of PV inverters across Europe. Two important European standards for PV inverters are EN 50524 and EN 50530.
Both the maximum voltage value and operating voltage range of an inverter are two main parameters that should be taken into account when stringing the inverter and PV array. PV designers should choose the PV array maximum voltage in order not to exceed the maximum input voltage of the inverter.
Our standardized solar power and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
