Danger of electric shock!
Only the intact and closed box shell can protect the safety of people and
property. Do not open the cover of the all-in-one when the all-in-one is working
or powered on, otherwise Stealth Energy will not be held responsible.
Danger of burns!
When the all-in-one is running, only touch the LED indicator and the DC switch.
It is strictly forbidden to touch the hot parts of the device (such as radiator, etc.)
during operation.
Danger of damage to the all-in-one unit or personal injury!
When AIO is working, it is forbidden to plug or unplug the PV connector, AC
connector and Bat connector.
All safety signs, warning labels and nameplates on the AIO must be clearly visible
and cannot be removed or covered .
NOTICE
Country selection and protection parameters must be set by professional
technicians according to local power grid standards. The wrong country
setting may affect the normal operation of the inverter, causing the AIO to be

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.
