Mode 5
In the purely off-grid mode, power
from PV will supply the back-up
loads first and then charge the
battery if there’re surplus.
Mode 3
In this working mode, the inverter
will use the power from PV or
grid (Set in the App) to charge the
battery until it is fully charged,
and as long as the grid is there,
the battery won’t discharge.
When the grid is cut off, power
from PV and battery will supply to
the loads connected in the back-
up side (UPS).
When the power from PV isn’t
enough, the battery will discharge
to supply back-up loads together
with PV.
Mode 4
In this working mode, you can set
charge/discharge power and time
in the App, inverter will use the
power from PV or grid(whether
to use can be set in the App)
to charge the battery in the
predetermined period.
Inverter will use power from PV
and battery to supply loads in the
predetermined period and the
insufficient part will be supplied
by the grid.

3.1.6 Off-grid Output Ability (UPS Ability)
Sunways STH hybrid inverter supports max 2times off-grid instantaneous overload of rated
output power, and each phase support 1.25times continuous overload of rated output power
but only one of them can reach 1.25times output power at the same time.
3.1.7 Storage conditions
1) Inverter must be stored in its original packaging.
2) The storage temperature should be in the range of -30 ° C and + 60 ° C, and the relative
humidity stored is less than 90%.
3) If a batch of inverters needs to be stored, the height of each pile should be no more
than 6 levels.
