Core offering

KOSTAL Solar Electric designs, develops, and manufactures photovoltaic inverters (PLENTICORE G3, PLENTICORE MP, PIKO CI series), battery inverters (PLENTICORE BI), modular high-voltage battery storage systems (HELIVOR), and EV charging wallboxes (ENECTOR G1/G2), along with energy meters, backup power switches, and monitoring software (Solar Portal, Solar 4me app). All hardware is engineered and produced in Hagen, Germany, and sold primarily through a certified installer partner network with a direct e-commerce webshop.

Product overview

KOSTAL Solar Electric offers a modular PV ecosystem centered on three inverter series: the PLENTICORE family (PLENTICORE G3 for three-phase residential/commercial 4-20 kW, PLENTICORE MP for single-phase homes 3-7 kW) and the PIKO CI series for commercial installations (30/50 kW and 100 kW). The ecosystem integrates the HELIVOR high-voltage battery storage and PLENTICORE BI 25 battery inverter for AC-coupled storage solutions. EV charging is addressed through the ENECTOR wallbox (G1 and G2). Digital tools include the Solar Portal web monitoring, Solar 4me mobile app, Solar Terminal configuration tool, Solar Plan design software, and Solar Calculator. Multi Device Control enables centralized management of up to three inverters. The system is extended through accessories including the BackUp Switch for backup power, Smart Energy Meter, and DC surge protection. PLENTICOIN activation codes unlock extended warranties and premium features. Products are designed and manufactured in Germany (Hagen, NRW) with automatic software updates.
