1.7 Battery Connection (please use only the SUNCLIX connectors
provided in the box)
1.7.1 Assembling the Battery Connectors
step 1 Strip the insulation from each DC cable by 7～8 mm.
step 2 Assemble the cable ends with the crimping pliers.
1: Positivecrimp contact 2: Negative crimpcontact
step 3 Lead the cable through cable gland, and insert the crimp contact into the insulator until it snaps into
place. Gently pull the cable backward to ensure firm connection. Tighten the ca- ble gland and the insulator
(torque 2.5 N.m to 3 N.m).
step 4 Check for polarity correctness.

1.11 Firmware upgrade
A manual firmware upgrade mightbe applicable to do the battery parallel configuration.
Please contact Sungrow service team before the commissioning.
There are two ways to do the manual firmware upgrade.
Method 1: Connect the inverter to the iSolarCloud, then ask Sungrow Service team to
upgrade.
Method 2: Request a firmware upgrade package from Sungrow, and do it locally.
1.11.1 Upgrading firmware locally
step 1 Connect to the inverter through local access. Refer to the link Local Access
Methods Guide
step 2 Change the Wi-Fi network on your mobile phone from your home network
to the Sungrow inverter network (network starting with SG). Open iSolarCloud app
again and click ‘Local Access’ → select WLAN access → enter the ‘user’ for the
account and “pw1111” for the password →click ‘Login’. (Figure 4).

Appendix
1. Assembling the SUNCLIX Connector
step 2 Pry the connection open and pull the sleeve and the insert apart.
step 3 Insert the stripped cable into the cable gland up to the stop. The stranded wire can be seen
inside the spring. Press the spring down until it audibly snaps into place.
During assembly, be careful not to contaminate, pull out, or shift, the seal in the ca-
ble gland. A contaminated or shifted seal impairs strain relief and leak tightness.
