The KSTAR BluE-S 5000D is a high-performance single-phase hybrid inverter (5kW) designed for modern residential solar energy systems with battery storage. Built for reliability, flexibility, and easy installation, it supports both on-grid and backup operation, making it an excellent choice for homeowners who want to maximize self-consumption and energy independence.

Designed for use with 48V LiFePO₄ battery systems, the BluE-S 5000D offers advanced energy management, efficient PV conversion, and seamless integration with smart monitoring via LCD, APP, WiFi, RS485, CAN, and optional 4G connectivity. It is especially suitable for residential installations where stable performance, backup capability, and compact outdoor-ready design are important.

With 2 MPPT trackers, a wide PV voltage range (80–560V), and up to 97.6% max PV efficiency, the BluE-S 5000D helps optimize solar harvest throughout the day, even when panel strings are installed across different roof orientations. The unit also features comprehensive protection functions including anti-islanding, insulation detection, short-circuit protection, and integrated DC switch + surge protection, helping ensure a safe and robust installation. 

Its IP65-rated enclosure and natural convection cooling make it suitable for installation, while the low-noise design makes it ideal for residential environments. The inverter is compliant with major international and European grid standards including EN50549-1, VDE-AR-N 4105, CEI 0-21, G98, and G99, supporting use across a wide range of EU markets.
