Called M250HV, up to 30 dc strings can be connected to its 12 max power point trackers, and the ac connection box has been designed to have space for handling of the heavy ac cables.
“Our experience in the field of inverters for utility-scale photovoltaic systems has gone into the development of the M250HV,” said Delta director Andreas Hoischen, “The result is a compact, easy-to-install and low-maintenance inverter that operates reliably even under the harshest environmental conditions.”
The company is showing the new inverter at Intersolar 2021 in Munich (6 – 8 October) alongside four new members of its Flex inverter series : M15A, M20A, M30A and M50A – intended for residential and commercial installations.
These Flex inverters have been built on the earlier M70A design (left).
“M50A is a technological twin of the M70A, which makes it easy to integrate into large rooftop installations,” said Delta. “Other features includes six maximum power point trackers for up to 12 dc strings for the M50A, optional dc SPD Type 1+2 and ground mounting.”
M15A, M20A, M30A are ac plug types for quick installation. They have Wi-Fi for integration and three maximum power trackers.
Delta will be at stand 120 in hall B5.
