2 Product description
2.1 AIO
AIO-S5 is a single-phase transformerless string photovoltaic energy storage
grid-connected integrated inverter, which is an important part of photovoltaic
power generation system. The all-in-one converts the DC power generated by
the photovoltaic panels into AC power that meets the requirements of the grid to
supply the load, and the rest is charged to the battery and fed into the grid.
AIO is only suitable for the energy storage grid-connected power generation
system described in this article.
Since the AIO is a transformerless type, it is required that the positive and
negative poles of the PV strings cannot be grounded, otherwise AIO will not be
able to operate normally.

Operation Mode Introduction
NOTICE
The above introduction describes the general working of a photovoltaic
system. The operation mode can be adjusted according to the system layout
on the Stealth Cloud App. The following are the general operating modes of
photovoltaic energy storage systems.
Depending on your configuration and layout conditions, PV energy storage
systems typically have the following modes of operation:
Self Use
The self-use mode is suitable for areas with low feed-in
subsidies and high electricity prices.
① When the power of PV is sucient
Active Charging or Discharge time period: PV will power the
loads rstly, and surplus power will charge to the battery .
If the battery is fully charged, then sell the surplus power to
the grid;
(PV ＞ Load, PV → Load → Battery → Grid)
② When the power of PV is insucient
Active Charging time period: PV will power the loads firstly
,the remaining power will be taken from the grid , the battery
will not discharge at this time.
(PV ＜ Load, PV + Grid → Load)
Active Discharge time period: PV+BAT will power the loads
together. If the power is still not enough, the remaining
power will be taken from the grid.
(PV ＜ Load, PV + Battery + Grid → Load)
AIO-S5 series, also known as hybrid or bidirectional solar inverters, is suitable for
solar systems with PV, battery, load and grid systems for energy management. The

The Feed-in priority mode is suitable for areas with high
feed-in subsidies, but has feed-in power limitation.
① When the power of PV is sucient
Active Charging time period: First, PV supply power to the
load, then charge the battery to the set capacity, and then
sell the power to the grid. If the local grid company limits
the grid-connected power of the inverter, the excess energy
continues to charge the battery.
(PV ＞ Load, PV → Load → Battery → Grid → Battery)
Active Discharge time period :PV will power the loads rstly,
and surplus power will feed-in to the grid.
(PV ＞ Load, PV → Load → Grid )
② When the power of PV is insucient
Active Charging time period:PV will power the loads rstly,
the remaining power will be taken from the grid. The battery
will not discharge.
(PV ＜ Load, PV + Grid → Load)
Discharge time period:PV+BAT will power the loads together.
If the power is still not enough, the remaining power will be
taken from the grid.
(PV ＜ Load, PV + Battery + Grid → Load)
③ Without PV power
Active Charging time period: The grid will power the home
loads and also charge the battery;
(PV=0, Grid → Load +Battery)
Active Discharge time period: The battery will power the
home loads firstly. If the battery power is not enough, the
remaining power will be taken from the grid. The inverter will
enter into the standby state.
