PV inverter is complemented with cloud-based monitoring apps
At EnerGaia 2019 in Montpellier, France, Delta Electronics will highlight the M70A solar PV inverter and PV monitoring apps.
The M70A solar PV inverter offers 77kVA maximum AC apparent power for ground-mounted and commercial solar rooftop systems.
The company has also developed MyDeltaSolar Cloud and PV monitoring apps for remote setup, monitoring, and control of solar photovoltaic systems.
The M70A is a three-phase string inverter with 77kVA maximum AC apparent power for ground-mounted and commercial solar rooftop systems. The design is compact and lightweight, making it easy to transport and install. There are six MPP trackers with three pairs of connectors each to allow system planners flexibility in arranging module strings and maximising yields. Module rows for ground-mounted systems require only minimal spacing as a result. Smart allocation of the MPP trackers can compensate potential shadowing, added Delta Electronics.
Even complex rooftop systems that have multiple sections with different alignments are easy to implement with the M70A, continued the company. If the system uses two strings per DC input, it does not require external string breakers.
Peak efficiency for the M70A is 98.8 per cent and it has a broad input voltage range from 200 to 1,100V DC. It can accommodate up to 18 strings via Amphenol connectors and string monitoring includes measurement of the I-V curve data at each individual string.
There are Type 2 surge protection devices pre-installed on the input and output sides and the inverter is supplied in a robust aluminum housing with IP65 protection.
The cloud monitoring service with free app for iOS and Android, 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. Delta’s M6A, M8A, and M10A inverters all ship 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.
