THE FUTURE OF SUSTAINABLE ENERGY
POWER WHEN NEEDED
A FLEXIBLE SOLUTION
Wattsonic All-in-one ESS is a smart hybrid energy storage system that turns solar
panels into an all-day resource while offering backup power in the event of a grid
outage. Wattsonic All-inone ESS enables storage of renewable energy, allowing
optimized home energy control and an increasing amount of total electricity
production to come from renewable sources. Reliable renewable energy improves
the resiliency of the grid, reduces energy costs, and increases the impact of electric
vehicle ownership.
Wattsonic All-in-one ESS enables the storage of energy from solar panels during the
day, or from the grid when energy rates are low; discharges energy for backup or use
at night; and automatically optimizes home energy. Wattsonic All-in-one ESS thereby
maximizes solar consumption and reduces energy spending.
Wattsonic All-in-one ESS can be charged from solar or grid power and can provide
backup power.
If greater amounts of energy are needed, multiple Wattsonic All-in-one ESS can be
installed together to work as a larger system.

Inverter Introduction
Basic features
Function
Wattsonic WTS series is also known as
hybrid inverter or storage inverter, which
is mainly used to combine the PV array,
lithium battery, loads and power grid to
realize intelligent power management and
dispatching.
The WTS 6~12kW series hybrid inverter
contains 4 models which are listed
below:WTS-6KW-3P,WTS-8KW-3P,WTS-
10KW-3P,WTS-12KW-3P.
Applicable grid type
The applicable grid types of the Wattsonic
WTS 6~12kW series are TN-S, TN-C, TN-
C-S and TT.When applied to the TT grid, the
voltage of N to PE should be less than 30V.
Schematic Diagram of Hybrid System
The hybrid solar system is usually composed
of the PV array, hybrid inverter, lithium
battery, loads and power grid.
Operation Modes
Wattsonic WTS Hybrid inverter has the
following basic operation modes and you can
configure the operation mode as per your
preference in the App.
General Mode
In this working mode, when the power from
the PV array is sufficient, PV power will
supply the loads, battery, and grid by the
following sequence:
Loads>Battery>Grid.
PV power will supply the loads with priority,
and secondly charge the battery if exceed PV
energy, and then feed to the grid. (You can
set the power to the grid to 0W if the local
grid doesn’t allow through APP or inverter
display).
When the PV power is insufficient, the
battery will discharge to supply loads, and
the grid will join in if the battery power is not
enough to supply loads. General Mode --- Suficient PV Generation General Mode --- Insufficient PV and Battery

10
Wattsonic AIO ESS | USER MANUAL
UPS Mode
Peak Load Shifting Mode
Setting Step: General Mode-->Pmax.
Economy Mode
In this working mode, set the Pmax from grid in the App can realize the “Peak
Load Shifting”. When the loads consumption less than the Pmax, loads are
supplied by the PV array and grid together.
Screen Setting step:
1. General Settings → WorkMode Set →General
Mode
2. Advanced Settings →Peakload Shifting →ON
3. Advanced Settings →SetMaxGrid → XXX
(kVA)
APP Setting step: General Mode →To Set
→Peakload Shifting ON → Set Max Grid (kVA)
In this working mode, the inverter will use the
power from PV or grid (Set by App) to charge
the battery with full power and top priority
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 suppy real-time loading connected
to inverter back-up port immediately within
10ms.
In this working mode, the customer can set
time-based scheduled charge and discharge
by App, inverter will use the power from PV or
grid(selectable by APP) to charge the battery
in the scheduled period.
* To realize the “Peak Load Shifting” function, the load power that exceeded
Pmax has to be within the inverter max output power, otherwise, the inverter
will only output the max power which allowed.
* During UPS mode, if battery long time no discharge, the inverter will discharge
and charge battery periodically(every 1 week) with small current roughly 1A to
to reset battery SOC.
When the loads consumption more than the
Pmax, the power exceeded Pmax (cannot be
higher than the inverter max output power)
will be supplied by the inverter. Inverter will
use power from PV array to supply loads first
and battery second if it isn't enough.
Inverter will use power from PV and battery to
supply loads in the scheduled period and the
insufficient part will be supplied by the grid.

Wattsonic AIO ESS | USER MANUAL
11
Off-Grid Mode
In the purely off-grid mode, power from PV
will supply the back-up loads firstly and then
charge the battery if there is surplus PV
generation.
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.
Off-grid peak load capability
Wattsonic WTS hybrid inverter overloading
ability in off-grid work mode describes as the
table:
When the power from PV is weak, the battery
will discharge to supply back-up loads together
with or without PV.
Off-Grid --- Charge
Off-Grid --- Discharge
* The multiples above are calculated based on rated output power.
* WTS-12KW-3P instantaneous max output power is 20kW.

①Max apparent power from the grid means the maximum power imported from the utility grid used to
satisfy the backup loads and charge the battery.
②The output power will exceed the rated value only when the power in the PV array is sufficient, and the
duration of the overload is relating to the overload power.
③Single-phase peak output power is the single-phase max output that won’t trigger overload protection,
only 1 phase can reach peak output power at the same time.

do not touch the inverter while it’s operating and inverter must be installed out of
reaching of children.
The area is completely water proof.
The floor is flat and level.
There are no flammable or explosive materials.
The ambient temperature is within the range from 0 to 50.
The temperature and humidity is maintained at a constant level.
There is minimal dust and dirt in the area.
The distance from heat source is more than 2 meters.
The distance from air outlet of whole system is more than 0.5 meters.
Do not cover or wrap the battery case or cabinet.
Do not place at a children or pet touchable area.
The installation area shall avoid of direct sunlight.
There is no mandatory ventilation requirements for battery module, but please avoid
of installation in confined area(minimum 300mm to top/left/right/front).
The aeration shall avoid of high salinity, humidity or temperature.
