The GoodWe 17-25 kW SDT G2 series inverter is especially designed for three-phase residential and small commercial projects. With its compact design, the SDT G2 inverter is 45% smaller than the first generation. The inverter is also light and easy to install. The maximum efficiency of this inverter is as high as 98.4%. With an advanced ventilation system, the inverter is able to dissipate heat efficiently. In addition, it can be customised with an integrated LCD screen.
GoodWe GW 25KT-SDT-G2 Grid-Tied 25 Kilowatts Three Phase Inverter Data Security
The inverter has data breakpoint resuming function, which means it can re-upload data to the monitoring system when it reconnects to the server after going off-line. The data is encrypted during the transmission process and data on the server has backup. All these features ensure data security.
