Solar inverter minimises shadowing
The M70A solar photovoltaic (PV) inverter has been launched by Delta. It offers 77kVA maximum AC apparent power and can be used for ground-mounted and commercial solar rooftop systems.
The M70A is a three-phase string inverter has a compact design and is light in weight, making it easy to transport and install. Six maximum power point (MPP) trackers with three pairs of connectors each give system planners flexibility to arrange module strings and maximise yields. Up to 18 strings are available via the Amphenol connectors. They also mean that module rows for ground-mounted systems require only minimal spacing, adds Delta. In addition, the intelligent allocation of the MPP trackers can compensate potential shadowing.
According to Delta, even complex rooftop systems that have multiple sections with different alignments are easy to implement with the M70A. If the system uses two strings per DC input, it does not require external string breakers.
The M70A allows string monitoring including the measurement of the I-V curve data at each individual string.
Type 2 surge protection devices are pre-installed on the input and output sides.
The solar inverter is supplied in a robust aluminum housing with IP65 protection.
MyDeltaSolar Cloud works with all Delta inverters and allows operators and installers to quickly set up and manage multiple systems and inverters. The system is available free of charge for five years with the purchase of a Delta solar inverter.
Users can monitor the performance of their Delta inverters in the MyDeltaSolar Cloud including current and voltage data. They can also see daily, monthly, and annual PV yields.
No cabling is required to connect a wireless-enabled Delta inverter to the new Delta DC1 data collector. The company’s M6A, M8A, and M10A inverters are shipping now with wireless communications pre-installed and wi-fi is an optional feature for the M70A. Alternatively, installers can connect to the MyDeltaSolar Cloud via the inverter’s RS485 interface. Delta hosts the cloud software on its own secure servers to guarantee maximum data security and protection against external threats.
