DELTA M70A_260 Flex inverter

The Delta WR M70A inverter, intended for large roofs, impresses not only with its robust design and housing. The efficient 70kW nominal power is particularly convincing, as it is the highest value in the area of ​​project solar inverters.

The transformerless 3-phase inverter is extremely flexible thanks to 6 efficient MPP trackers and can handle a maximum voltage of 1100 volts.

The WR M70A offers the option of wireless communication and also via RS485 with potential-free contacts and digital inputs. This guarantees easy operation and commissioning.

The peak efficiency of 98.7% speaks for maximum efficiency. The model is also capable of string monitoring.
The easy cleaning of the external fan assembly with 4 fans is also an advantage. These are replaceable and their airflow runs from the AC terminal to the DC switch.

Thanks to its robust aluminum housing, which offers long-term protection against moisture and corrosion, it is suitable for indoor and outdoor applications according to IP65.

The scope of delivery includes 12 Amphenol H4 DC plugs.

The M70A is suitable for both rooftop and ground-mounted PV systems.

This inverter has both the option with stand mounting (2 x mounting feet per M70A), as well as with the DC+AC surge arresters type 1+2, of which only one piece is required (information on this can be found on pages 66ff of the instructions). When using 3 strings per MPPT, additional external backups are required.
