Inverter KSTAR 5-8kW single-phase Blue-G

The single-phase inverter KSTAR BluE-G 5–8 kW is designed for modern home solar power plants. It is a reliable and efficient voltage converter. One series covers all 5–8 kW power models, so the solution can be adapted to the specific power and electrical input characteristics of a specific solar power plant. The inverter operates on a 230 V, 50/60 Hz network and easily integrates into the existing home electrical system.

With two independent MPPT trackers, two separate rows of solar modules can be connected to the KSTAR single-phase inverter BluE-G. This feature is useful when the modules are installed on different roof slopes or when part of them is covered by shade at certain hours, thus the overall production of the solar power plant remains more stable. The inverter's operating DC voltage range from 80 to 560 V (maximum voltage – 600 V) is also suitable for larger, higher voltage systems.

KSTAR BluE-G 5–8 kW power has been increased (DC/AC ratio up to 1.5), so you can install more solar modules than the nominal inverter power and get more electricity on cloudy days or in the mornings/evenings. This is especially relevant in Lithuania, where the sun does not always shine at maximum intensity.

The maximum efficiency of the KSTAR single-phase inverter reaches up to 98.3%, so more of the energy produced by the solar modules is converted into useful electricity, and losses are reduced. The inverter remains effective both when operating at low loads and when approaching nominal power, and the solar power plant pays for itself faster. Small dimensions (380 × 380 × 150 mm) facilitate installation, and the lightweight housing is convenient when the KSTAR single-phase inverter is installed by one person.

The device cools naturally, operates extremely quietly, and can be installed even in or near residential areas. The IP65 sealed housing protects the inverter from dust and rain, and it can be installed both outdoors and in unheated or humid rooms. Additional protection against voltage surges on the DC and AC sides reduces sensitivity to network fluctuations and lightning-induced surges.

The KSTAR single-phase inverter has an integrated DC disconnector and basic protections - against overcurrents, leakage currents and insulation faults. This protects both the device itself and the electrical installation of the house.

The WiFi or 4G connection plug provides remote access to the operating data of the KSTAR single-phase inverter - the solar power plant production schedule, voltage and current readings, energy balance, and warnings about malfunctions are visible.
