Installation 5. InstallationE) Push the AC terminals along the rail to the inside of the inverter then tighten the screw under rack.Lock the 4 screws of AC terminal and tight the cap nut of AC terminal (as shown in figure 5.21).To protect the inverter's AC grid connection conductors, Ginlong Solis recommends installingbreakers that will protect against overcurrent. The following table defines OCPD ratings forthe Ginlong Solis 40-70kW Three phase inverters.Solis-40KSolis-70K-HVSolis-60K-HVSolis-50K-HVSolis-50KTable 5.2 Rating of grid OCPDInverter Ratedvoltage(V)Rated outputpower (kW)Current for protectiondevice (A)There are 3 communication terminals for Ginlong 40-70kW inverter. COM1-COM3 are all for RS485communication. COM1 is 4-pin connector which matches with the Ginlong Wi-Fi or GPRS wirelesscommunication products.COM2 and COM3 are RJ45 and terminal block for RS485 connection, which is used for communicatingconnection between inverter and data logger.Figure 5.22 is the internet monitoring solution.
