Hi,
I have 2 x 300ah lifepo4 // mode ( bms buit in) with mppt 150/70 connected to 2 x 335w solar panels . Mppt is setup to default Lifepo4 . The strange thing is i know the SOc is around 50%. In starting day the mppt is in Bulk mode, very quickly it’s moving to Absorbtion ( around 2 hours ) and 1 hour after it’s mouving to float...so i never reach 80% ( the goal) or 100% . I have to disconnect panel then the cycle start again. I’m in a very sunny country where i can charging 40a/h during 5 hours ( so 200ah expected), What’s wrong ?
