levels of efficiency and provide longest operating life by use of state-of-the-art
high frequency and low EMI switchmode technology.
- 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.

- M100_210 / 212 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.
