8.8 kW Three-Phase Inverter Designed for Medium-Scale Photovoltaic Installations

This device converts DC current from PV panels into grid-compliant 3-phase 400 V AC, ensuring stable and efficient system operation. With a maximum efficiency of 98.5%, it minimizes conversion losses—every additional kWh generated by the panels goes to usable energy, not heat. The transformerless topology reduces weight and increases reliability while eliminating voltage transformation losses.

Two independent MPPT channels allow connection of two separate panel strings—e.g., with different tilt angles or orientations—without performance loss. Even if one string is shaded, the other continues operating at full capacity. The wide DC input voltage range (140 V to 1000 V) offers flexibility in panel selection, while a startup voltage of 160 V ensures rapid system activation even under low irradiance.

Protection, Communication, and Installation Integrated in One Unit

The inverter features a built-in DC isolator, enabling safe disconnection of panels during maintenance or faults without requiring additional equipment. The IP65 protection rating allows outdoor mounting—no need to house the unit inside a cabinet or utility building. The housing, made of aluminum and stainless steel, is corrosion-resistant, and passive cooling eliminates the risk of fan failure.

Communication is supported via WiFi, LAN, and RS485—system performance can be monitored through a mobile app in Polish or integrated with an energy management system (EMS). Data is stored for 25 years, and standby power consumption does not exceed 1 W. Noise levels remain below 40 dB—operating quietly even when mounted against a house wall.

Compliance and Operating Conditions

The device complies with safety standards IEC 62109-1/2 and grid requirements VDE-AR-N 4105, CEI 0-21, and EN 50549—approved for connection in Poland and the EU. It operates in temperatures ranging from -30°C to +60°C and at altitudes up to 4000 m a.s.l., making it suitable for both northern regions and mountain rooftops. Automatic protection against reverse polarity, islanding, and leakage current requires no user intervention.
