The KSTAR BluE-S 3680D is a high-performance single-phase hybrid inverter (3.68kW) designed for modern residential solar energy systems with battery storage. Built for reliability, flexibility, and easy installation, it supports both on-grid operation and backup power (EPS). This makes it an excellent choice for homes looking to maximize self-consumption and increase energy independence.
The BluE-S 3680D is compatible with 48V LiFePO4 battery systems and offers advanced energy management, efficient PV conversion, and smart monitoring via LCD, app, WiFi, RS485, CAN, and optional 4G. Thanks to its compact design and robust housing, it is ideal for residential installations both indoors and outdoors.
With 2 MPPT trackers, a wide PV voltage range of 80–560V, and a maximum efficiency of up to 97.6%, the BluE-S 3680D helps optimize solar production even when panels are installed on different roof orientations. The inverter also includes comprehensive protection features such as anti-islanding, DC reverse polarity protection, string fault detection, short-circuit protection, and an integrated DC switch + AC/DC surge protection for a safe and stable installation.
Its IP65 protection rating and natural convection cooling make it suitable for indoor and outdoor installation. The low-noise design (<25 dB) is ideal for residential environments. In addition, the inverter complies with major European grid standards including EN50549-1, VDE-AR-N 4105, CEI 0-21, G98, and G99, making it widely usable across Europe.
