DELTA M70A_260 Flex

The Delta WR M70A inverter, which is designed for large roofs, not only impresses with its robust design and housing. The 70kW nominal power in particular are convincing, since this is the highest value in the field of project solar inverters.
Thanks to 6 efficient MPP trackers the transformer-less 3-phase inverter is extremely flexible and can cope with a maximum voltage of 1100 V.
The WR M70A offers the possibility of wireless communication as well as per RS485 with potential-free contacts and digital inputs. This guarantees simple operation and start-up.
The peak efficiency of 98.7% is an indicator of maximum efficiency. In addition, the model is string monitoring-compatible.
Simple cleaning of the external fan assembly with 4 fans is a further advantage. These can be replaced and their air flow runs from the AC terminal to the DC switch.
Thanks to its sturdy aluminium housing, which provides long-term protection against humidity and corrosion, it is also suitable for indoor and outdoor applications in accordance with IP65.
The scope of delivery includes 12 Amphenol H4 DC connectors.
The M70A is suitable for both roof-top and ground-mounted photovoltaic systems.

This inverter is available both as the option with floor installation (2 x installation feet per M70A) and also with the type 1+2 AC and DC surge protectors, of which only one unit each is required (information about this can be found on p. 66ff of the instructions). When 3 strings per MPPT are used, external fuses are required in addition.
