The grid-connected single-phase inverter for PV and energy storage systems Growatt has joined the Tigo Enhanced program to offer PV installers quick shutdown solutions. Growatt's newest line of single-phase hybrid inverters – the XH series – will integrate RSS (Tigo Rapid Shutdown System) transmitters and enable plug-and-play installation with Tigo's industry-leading Rapid Shutdown devices.

The rapid shutdown at module level, which is made possible by the rapid shutdown devices from Tigo, is required according to the current NEC standards (National Electrical Code). When customers see the Tigo Enhanced logo on Growatt inverters and technical data sheets, they can be sure that the inverters will reliably perform the required safety functions with Tigo emergency shutdown devices and meet the required electrical codes and standards.

“We are very excited to be working with Tigo to offer customers a truly integrated quick shutdown solution,” said Felix Fang, CEO of Growatt USA, Inc. “Our customers want solutions that work together seamlessly, and that's what we offer with our new XH Inverter solution and battery. “

The XH series from Growatt with an output of 3.0 kW to 11.4 kW and are battery-ready when purchased or can be easily retrofitted if customers want to add energy storage in the future. Each inverter displays a Tigo Enhanced logo, which enables customers to quickly identify models that are out of the box with Tigo TS4-AF and TS4-A-2F products. The inverters also have integrated 4G / Wifi or Wifi / LAN and are seamlessly integrated into the Growatt monitoring and mobile app.

The XH product line is included in a long list of Growatt inverters ranging from 3 kW single phase to 40 kW three phase, UL PVRSS (PV Rapid Shutdown System) certified and certified with Tigo Rapid Shutdown devices.

UL PVRSS certification is the only guaranteed way to meet the safety requirements for PV Rapid Shutdown in the US National Electrical Code, whereby both the inverter and the Rapid Shutdown device must be tested as a “system”. Rooftop PV installations in the vast majority of the US now require quick shutdown devices. Similar requirements are accepted and discussed worldwide.
