RECs aktive BMS for 4 celler koblet i serie, vil gi aktiv bi-directional balansering. Denne BMS-en er velprøvd, og vi på Farco har erfaring med bruk av den siden 2015. Dette betyr at den står i mange anlegg og er gjennomtestet. At den er aktiv gjør at den har stor kapasitet. Fra 2019 leverte vi denne i en utgave som er Victron kompatibel. Dette gjør at BMS styrer ladespenning og styrke, og fungerer meget godt med Victron produkter som kommuniserer via GX løsning med VE.BUS
Husk å bestille kabelsett sammen med BMS!
REC har laget en Video som viser en standard oppkobling.
