Users are able to set end of discharge (stop d ischarging) battery level when there is grid. This setting
is important for some area where always has load sheddings.
Since in some countries, users can not feed energy into grid, so they are able to disable energy export
function in the LCD, or set power percent which can feed into grid.

For parallel system, users need to set one inverter to master and others to slave. If the system is single phase, then
users need to choose 1 phase master, if the system is three phase, then users need to choose 3 phase master.
For parallel system, the inverter is able to detect the phase auto if there is three phase grid input. If the application is
pure off grid three phase application, users need to set the phase output for each inverter. For master, it is considered
as R phase.

4.5 Parallel system setup guidance
Please note that the parallel model is different from standard model, if users need to connect the UPS
together, they need to buy parallel model from distributors.
For parallel system setup,
Step1. Cable connection :the system connection for single phase paralleling is as below:
the system connection for threephase paralleling is as below:
4.4 Work with Gen set
All lux units can work with generator.
Users can connect the generator output to inverter Grid terminal. If you have both grid and generator as AC input,
we need an external ATS to switch between grid and generator.
Please purchase an external control box to remote turn on/off the generator(which support dry contact function).
The generator will be automatically started when battery voltage is lower than the cut-off value or there is charge
request from BMS. When voltage is higher than AC charge setting value, it will stop the generator
