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
c o n t a i n s 4 m o d e l s w h i c h a r e l i s t e d

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
