FAQ
Dear Livoltek users or installers, here you will find our most frequently asked questions and their answers, which we have grouped together in order to help you solve your problems quickly.
Off Grid Inverter
Livoltek off grid inverter is compatible with Livoltek Li-ion battery, Pylontech 48V with CAN
communication and 48V lead-acid battery.
There are four ways to upgrade.
1. Upgrade from the app after connecting the inverter with smart phone bluetooth.
2. Upgrade by U disk.
3. Upgrade from LCD screen.
4. Upgrade from Livoltek platform when the inverter is online.
There are backup mode, economic mode and off-grid mode.
Backup mode is advisable for users who live in an area where power outages happen
frequently.
Economic mode is advisable for users who have solar panels and the electricity is expensive.
Off grid mode is for no grid area users. This mode does not need to be set from the App.
Please turn on the ON/OFF switch at the bottom of the off grid. If it is turned on, please
connect off grid with bluetooth and check what fault is happening or contact Livoltek technical
support.
Lithium batteries do not need to set parameters because the inverter can communicate with
BMS. However, for lead-acid batteries or lithium batteries with no BMS, parameters need to be
set.
The beep sound can be turned off from App at Settings-Basic settings-EPS setup-Beep on EPS.
Currently, Livoltek single phase off grid inverters can be paralleled to a maximum of 3
inverters.
Yes, Livoltek off-grid inverter can work without battery connected. Please note this does not
work when multiple off grid inverters are paralleled.
