I have a system that includes the SmartSolar 150/70 networked with a Venus GX and BMV 702. The battery is 24 volts and 258 Ah. The charge controller consistently switches from Bulk to Float seemingly prematurely -- when the BMV indicates that the battery is at around 81-82%.
The battery has a charge limit voltage of 29.2, but I have tried to be conservative with my max voltage setting for the charge controller -- I have it set to 29.0 volts currently. I understand that it shouldn't charge to 100% with that setting (nor do I want it to charge fully out of battery care considerations), but I should think that it ought to charge higher than 80%. Based on the history, I don't see it touching 29 volts even momentarily which might cause the battery to trigger the mppt to change to Float. It seems to get no higher than around 28.8 or so.
Any suggestions? TIA!
