Questions & Answers (Q & A)
About the Wi-Fi Configuration
Q: Why can't I find the Solar-Wi-Fi* signal on mobile devices?
A: Normally Solar-WiFi* signal can be found right after inverter has powered up. But
Solar-Wi- Fi signal will disappear when LGES inverter connects to internet. If changes to the
setting are required, connect to the router for change. If you can't find the WiFi signal
or connect to the router, then please try to reload Wi-Fi (please refer to User manual
page 21).
Q: Why can't I connect to the Solar-Wi-Fi* signal on my phone?
A: The Wi-Fi module can only connect to one device at a time. If the signal is already connected to
another device at the same time, you will not be able to connect to the signal.
Q: Why does the Wi-Fi module fail to connect to network after I choose the right router hotspot and
enter the right passwords?
A: It's possible that there are special characters not supported by module in the hotspot passwords.
Please modify the password to consist of only Arabic numerals or uppercase /lowercase letters.
About Battery Operation
Q: Why does the battery not discharge when the grid is not available but it discharges normally when
the grid is available?
A: In the APP, the off-grid output and backup function should be turned on to force the battery to
discharge under off-grid mode.
Q: Why is there no output on the backup side?
A: For backup supply, "Backup Supply" on the LGES PV Master App must be turned on. In off-grid
mode or when the grid power is disconnected, the "Off-Grid Output Switch" function must be turned
on as well.
Note: When turning the "Off-Grid
the function will be switched off automatically.
Q: The battery cannot be fully charged to 100%?
A: The battery will stop charging when the battery voltage reaches the charge voltage set on LGES
PV Master App.
