Growatt unveils EV chargers for residential and commercial applications


Chinese inverter and battery manufacturer Growatt has an electric vehicle (EV) recharging station for residential and commercial applications.

The Thor charging station is available as both AC and DC chargers.

The AC products are the Thor 03/07ASS and 03/07ASP chargers, which have an output of 3 and 7 kW, respectively, and a charging time of about 7-15 hours; and the Thor 11/22ASS and Thor 11/22ASP stations, which feature both a nominal power of 11-22 kW and a charging time of between one and four hours.

The DC chargers are the 750 V(DC) Thor 40DDP and Thor 40DSP stations, both with charging times of about one to two hours. All charges integrate the company's internet-of-things (IoT) “GroHome” technology, which Growatt says allows remote control, multi-zone control, voice control, and smart scheduling. Users are reportedly able to monitor the system through a dedicated app called “ShinePhone.”

All systems are compatible with all branded electric vehicles and PV modules, the manufacturer said.

“Thor supports three different charging modes — Fast Mode, Off-Peak Mode and PV Linkage Mode,” the manufacturer explained. “With Fast Mode, the EVs can be charged with maximum speed, while Off-Peak Mode allows users to charge their EVs during off-peak hours, with less charges from the grid.”

With fast mode and off-peak mode, the charger can be powered by surplus solar power and the grid, and under these two modes, it doesn't require the surplus solar power to be greater than minimum operational power. This is, however, required under PV Linkage Mode.

“Thor’s advanced, built-in, type A+ 6 mA DC fault protection saves the cost of installing an extra 6 mA DC RCD, while its smart load balancing function can adjust its charging power dynamically according to the limited home power, and avoid breaking the fuse and causing [a] power outage, making it safe to use for customers,” Growatt added.

*The article was updated on November 9 to specify that the Thor 03/07ASS and 03/07ASP chargers have an output of 3 and 7 kW, respectively.
