2.1 Intended Use
Thank you for purchasing an inverter from Jalpower Company. JSI10KTL, JSI12KTL
and JSI15KTL serial inverters are grid-connected, transformerless, robust and high
conversion efficiency.
The inverter converts DC power generated from the PV arrays into stable AC current,
and then feeds this into the utility grid. The grid is three-phase four-wire type or
three-phase five-wire type. Inverter is crucial unit in the small-scaled
system. PV power
An example about intended use of this inverter is show in Fig 2-1.

Any other or additional use is not pe
r
mitted except the intended use.
The inverter must only be connected to public utility grid.

Installation
If output of in

r
te
r
is connected to local loads (household appliance, lights,
motor loads, etc.), the inverter will stop working.
2.2 Main Circuit
Following shows the main circuit of JSI15KTL----a transformerless
grid-connected inverter. JSI10KTL and JSI12KTL have the similar main circuit.
There are two MPP trackers designed for input. The boost stage levels up the input
DC voltage to a desirable value for the inverter. Then an IGBT three-level inverte
r
circuit converts the DC power to AC power. This AC power is fed into the utility grid vi
a
AC EMI filter.

When choosing the installation site, Ensu
r
e that there is no elect
r
omagnetic
interference with other electrical and electronic equipments.
Requirements:
12
The humidity of chosen installation site never exceeds 95%.Moisture may result in corrosion to
the lid and damage to the inner electronic components.
The chosen installation site maintains ambient temperature range from -25
° C to 60 ° C. When the
temperature exceeds 45
° C, the output power will reduce.
Do not install the unit in the direct sunlight or in an enclosure exposed to the direct sunlight.
Exposure to the sun may cause additional internal heating. This can result in reducing output
power.
The wall selected should be strong enough to hold the weight of the inverter.

Do not install the inverter in living area. Noise can be produced during running of the inverter,
which will affect your daily life.
Do not install the inverter in this site where the children can reach. The housing of the inverter will
be very hot. It is risk of burning.
Install the inverter at eye level. Meanwhile some space at the bottom needs to be kept for
electrical connection.
