Ausgewählte Produkte

Das JKBMS ESS Inverter BMS (JK-PB Serie) wurde speziell für Heimenergie-Speicher-Wechselrichtersysteme entwickelt. Im Gegensatz zu Standard-Smart-BMS-Einheiten integriert sich die JK-PB Serie direkt mit Solarwechselrichtern über integrierte Kommunikationsprotokolle und ermöglicht so ein vollautomatisches Lade- und Entlademanagement als Teil eines kompletten Heim-ESS-Systems.

Verfügbar in Stromstärken von 100A, 150A, 200A und 300A für 16S LiFePO4 Batteriekonfigurationen. Optionale 7-Zoll- und 4,3-Zoll-LCD-Displays sind separat erhältlich.
