Delta M88H_121 ST high efficiency three phase transformerless inverter - perfect choice for large-scale solar PV systems, such as those used in the commercial or utility sectors

Maximum profitability

The M88H Inverter has a peak efficiency of 98.8% and has built-in and replaceable AC and DC-side Type II SPDs (surge protection devices). Maximum apparent power 73 kVA / 88 kVA (400 VAC / 480 VAC).

Flexible applications

Suitable for 400V or 480V AC Grid voltage, Al or Cu cables and 18 x MC4 connector pairs (CF) with string monitoring or DC screw terminals (ST). 2 MPP trackers and a high maximum input voltage up to 1100V allow for extra flexibility in system design.

Convenient wiring box

Convenient and separate wiring box available with built-in Type 2 AC and DC SPDs and certified to protection class II. Two variants: CF model includes 2 x 9 pair Multi-Contact MC4 connectors and string fuses; ST model features AC and DC Terminal Blocks.
