Sungrow SG3KTL-M Manuals

1. Turn off the DC switch and then disconnect the AC circuit breaker. Prevent them from inadvertently reconnecting during inverter installation. 2. Secure the backplate to the wall with the provided mounting kits. Hang the inverter to the two recesses of the backplate.To protect the inverter from theft, you can lock it to the backplate with a padlock. 3. Allow sufficient room around the inverter to enable unobstructed air flow during installation. For multiple inverters installation, positionthe inverters in staggered arrangement. 2 Mounting Inverter onto the Wall This guide provides a general instruction of the installation procedure of SG3KTL-M/SG4KTL-M/SG4K6TL-M/SG5KTL-M. 1 Installation Preparation Select appropriate cables before securing the inverter to the wall.

Install backplate Hang inverter Mounting ear Backplate • The theft protection is optional. • You shall lock the inverter to the mounted eye plate of the backplate with a suitable (stainless, secured shackle and lock cylinder) padlock. • You must ensure that the key is available at all times for possible service purposes. 5. The inverter is equipped with second protective earth terminal as specified in EN 50178. Users may choose to connect PE connection. The PV input configuration mode should be consistent with the setting in the LCD. 4. Plug the AC connector into AC terminal placed underneath the inverter. Connect the “PE” cable to the grounding electrode and connect the phase cable and “N” cable to the AC circuit breaker as shown on the right. 6. Check the cable polarities of PV input before PV input connection. Connect the DC plug-in connectors to corresponding DC terminals. Connect other PV strings following the same procedures if necessary. Unused DC terminals should be sealed. The inverter can work on independent mode and parallel mode, you can connect PV input as shown (In parallel mode, one pair of DC terminals in DC1 input and DC2 input must be short-circuited by Y-type cable connector terminal.).
