1.1 Information of the Inverter
1.1.1 Legal Provisions
This manual is prepared for use by well-trained technician for installing, commissioning,
operation, and maintenance. The technician must have the following basic and
advanced skills:
• Knowledge of the fundamentals of electricity, wiring, electrical components and
electrical schematic symbols.
• Knowledge of how a solar inverter works and is operated.
•
Training in
the installation and commissioning of electrical devices and installations.
•
Training in
how to deal with the dangers and risks associated with installing
and using electrical devices and installations.
• Compliance with this manual and all safety information.
1.1.2 Target Group
Safety

1.2 General Safety
- 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, L3 or N 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.
- M100_210 is a transformerless solar inverter with 1 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 10μF.
- The inverter should be operated in countries which are approved by DELTA
and the grid operator.
1.2.1 Condition of Use

2Introduction
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.
- It is prohibited to connect terminals L1, L2, L3 or N to ground.
ATTENTION : NO GALVANIC ISOLATION
- M100_210 has been tested and found to comply with the limits for IEC 62910
Class A which is designed to provide reasonable protection against harmful
interference in the commercial environment operation.
- This device generates radiofrequency energy, please accord this manual to
install and use.
- Operation in a residential area could cause harmful interference.
ATTENTION : Intended for Industrial Environments

Figure 2-3: Rating label
Symbol Definition
Danger to life through electric shock
Potentially fatal voltage is applied to the inverter during operation.
This voltage persists even 60 seconds after disconnection of the power supply.
Never open the inverter. The inverter contains no components that must be maintained or
repaired by the operatoror installer. Opening the housing will void the warranty.
Before working with the inverter,
you must read the supplied manual
and follow the instructions contained
therein.
This inverter is not separated from
the grid with a transformer.
The housing of the inverter must
be grounded if this is required
by local regulations.
WEEE marking
The inverter must not be disposed
of as standard household waste,
but in accordance with the applicable
electronic waste disposal regulations
of your country or region.

enough to carry the weight.
2. Orient the wall bracket (Figure 3-5) horizontally (perpendicular to the floor).
3. Secure the mounting bracket on the wall with 12 M6 screws.(Figure 3-6)
4. Hang the inverter on the wall mounting bracket.
5. Two external grounding points can help to fix the inverter by 2 M8 screws.
3.2.1 Wall Mount
- The mounting bracket shipped with the unit is specially designed and is the only
certified mounting device for mounting the inverter.
- Secure the mounting bracket on the wall with at least 8 M6 screws.
