1.2 General Safety
- The inverter is not equipped with a transformer and has no galvanic isolation.
- Do not operate with grounding PV modules.
- It is prohibited to connect L1, L2, L3 and N terminal to ground.
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

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 indoor and outdoor use.
- The M15A_220 / M20A_220 is a transformerless solar inverter with 2 MPP
tracking inputs, which converts the direct current from the PV array into
grid-compliant three-phase current and feeds it into the utility grid.
- The photovoltaic modules used must be compatible with the inverter. PV modules
with a high capacitance to ground must only be utilized if the coupling capacity
does
not exceed 5μF.
- The inverter must only be operated in countries for which it is approved by
DELTA and the grid operator.
