High efficiency and smart energy flows make Kostal Plenticore G3 and Kostal Plenticore Plus inverters the optimal choice for modern PV systems. Kostal is a leading German manufacturer of innovative inverters and energy management systems, with smart interfaces and high reliability.
KOSTAL develops innovative and sustainable energy solutions to optimize self-consumption, increase self-sufficiency, and use renewable energy intelligently. Quality “Made in Germany” is at the core—especially the KOSTAL PLENTICORE plus and KOSTAL PLENTICORE G3 inverters are in high demand.
The KOSTAL PLENTICORE G3 is the latest hybrid inverter that can be flexibly used as a PV inverter, battery inverter, or hybrid inverter. Thanks to 3 MPPTs, it offers multiple options for connecting solar modules, with one input optionally usable as a battery connection. With a separate changeover device, the KOSTAL PLENTICORE G3 is also capable of backup power (emergency supply). In addition, the KOSTAL PLENTICORE G3 offers several interfaces such as LAN, Wi-Fi, 4 digital switching outputs, and SG Ready, making it smart-home compatible. If more power is needed, higher output levels can be unlocked on the base units. From firmware 3.04.03.19410 onwards, the KOSTAL PLENTICORE G3 can be fully integrated via EEBUS.
The KOSTAL PLENTICORE plus is a PV hybrid inverter with 3 MPPTs, with one input optionally usable as a battery input. Thanks to its self-learning shade management, the KOSTAL PLENTICORE plus can respond to shading and does not remain stuck in a local MPP range. The device is smart-home ready via LAN, Wi-Fi, 4 digital outputs, and SG Ready.
Whether for single-family homes or commercial businesses—KOSTAL offers inverters for every application: from single-phase units for small roofs to hybrid inverters with backup power functionality.
