About Utility-Interconnected Photovoltaic inverters ISI Certification
Utility-interconnected photovoltaicInverter is the source to save energy, also known as solar inverters. Agrid-connected photovoltaic system is an electricity generating solar PV powersystem that is connected to the utility grid. A grid-connected PV systemconsists of solar panels, one or several inverters, a power conditioning unitand grid connection equipment. The goal of this standard is to define therequirements for connecting PV systems/inverters to the utility distributionsystem, as well as to provide a test procedure for evaluatingutility-interconnected photovoltaic (PV) power systems that operate in parallelwith the utility and use static (solid-state) non-islanding inverters for DC toAC conversion. On 30 June 2020, the Bureau of Indian Standards (BIS) hasrequired Utility-Interconnected Photovoltaic inverters to be registered as perIS 16221: 2015 & IS 16169: 2014 under the Compulsory Registration Schemefrom BIS.
Efficient Protection MechanismsThese photovoltaic inverters are equipped with sophisticated safety features such as over-voltage, over-current, and short-circuit protection. Islanding protection and an anti-islanding relay safeguard the utility grid, ensuring safe operation and enhanced security during grid failures or faults.
Comprehensive System MonitoringThe integrated LCD display provides instant access to critical system parameters, facilitating effective monitoring and maintenance. Real-time data enables precise control of operational performance, helping users make informed decisions and respond promptly to any issues.
Flexible Installation and ConnectivityDesigned for ultimate versatility, the IP65-rated enclosure allows both indoor and outdoor installation. Connectivity options including RS485, Ethernet, and optional Wi-Fi ensure seamless communication and integration with modern monitoring solutions.
