Page 6: Photovoltaic Hybrid Solar Converter (Zero Export Inverter)
The Hybrid Converter / Inverter can convert solar panel DC power into AC power, which can directly input to the grid. This manual is used for SUN-1K-G, SUN-2K-G and SUN-3K-G models and the appearance of these inverters is shown in Figure 2. -
Page 7: Parts List
Improper use of the inverter will cause electric shock and burn during the installation and maintenance. Please read the user manual carefully before using the inverter. Also, operate the inverter in strict accordance with this manual and please keep the instructions properly for afterward use. Website: www.sunsynk.com E-mail: sales@globaltech-china.com... -
Page 8: Safety Signs
While disconnecting the input and output of the inverter for maintenance, please wait for at least 5 minutes until the inverter discharge the remnant electricity. Shock Hazard: When the solar array is exposed to sunshine, it will generate a high DC voltage on it. It is prohibited touching. Website: www.sunsynk.com E-mail: sales@globaltech-china.com... -
