1.2 General Safety
- External insulation transformer shall be installed at grid side which is following
to isolating between AC and PV array.
- The design of this inverter is transformerless. There is no isolation transformer
between the AC and DC sides, i.e., the product does not require galvanic isolation.
In order to function properly, any PV array connected must have its PV circuits
isolated from ground, i.e., do not bond either side of the array to ground!
If a grounded PV array is connected to the inverter, the error message INSULATION
(E34) will appear on the display.
- It is prohibited to reference the L1, L2, or L3 terminal to ground; to do so will
damage the inverter and void the producr warranty.
ATTENTION : NO GALVANIC ISOLATION
- Please read these instructions carefully and save them for later use.
IMPORTANT SAFETY INSTRUCTIONS : SAVE THESE INSTRUCTIONS !
To prevent personal injury and/or property damage, and also to ensure long
term operation of the solar inverter, it is imperative this section be read carefully
and all the safety instructions understood before using this inverter.
This user manual provides important instructions for Delta grid-tie transformerless
solar inverter. The product is designed, tested, verified, and certified according
to international safety requirements, certifications, and standards but precautions
must be observed when installing and operating the product.
This product is suitable for both indoor and outdoor use.
- M125HV_113 is a transformerless solar inverter with single MPP tracking input,
which converts the variable direct current generated by the solar array into a
utility frequency grid-compliant balanced three-phase AC current and feeds
it into the utility grid.
- The Photovoltaic modules used must be compatible with the inverter. PV
modules with a high parasitic capacitance to ground may only be utilized if the
capacitive coupling does not exceed 20μF.
- The inverter must only be operated in countries for which it is approved by
Delta and the grid operator.

Safety

M125HV_113 transformerless 3Ø PV inverters are designed to enable the highest
levels of efficiency and provide longest operating life by use of state-of-the-art
high frequency and low EMI switchmode technology. It is suitable for outdoor use.
The user manual is valid for the following device types:
• M125HV_113
• DC Wiring Box
This user manual must be followed during installation, operation, and maintenance.
DELTA reserves the right to make modifications to the content and technical data
in this user manual without prior notice.
2 Introduction
2.1 Valid Model
- This product utilizes a transformerless design, and is not provisioned with an
isolation transformer, and therefore has no galvanic isolation between the DC
and AC sides.
PV array circuits connected must be floating with respect to ground, i.e., must
not be referenced (bonded) to ground.
If grounded PV arrays are connected to the inverter, the inverter will not connect
to the grid and the error message INSULATION (E34) will appear on the display.
- It is prohibited to connect terminals L1, L2, or L3 to ground.

Figure 3-5 provides the mechanical dimensions of the inverter.
3 Installation
- In some locations, mounting the inverter in direct sunlight may cause the inverter
to enter a thermal derating mode. To eliminate this concern, a shade structure
over the inverter chassis may be necessary.
CAUTION !
WARNING !
- Do not install the unit near or on flammable surfaces.
- Inverter must be mounted securely to a solid / smooth surface.
