I`m after the correct settings for Bulk Charge and Float voltage for flooded lead acid batts. The charge is via a controller for PVs.
The instruction manual says for flooded lead acid: Bulk 14.8v; Float 13.5v. (For sealed gel type lead/acid it says 14.3 and 13.5 respectively.)
If a wet lead acid is normally fully charged at 12.6+(Ed Sherman), those values seem too high, suggesting the charger would be "boiling" the batteries. So I set Bulk at 13.6v and Float 13.2v, but it`s easy to reset them.
While on the subject, the controller has an equalization phase. I turned it off, my understanding is it kicks sulphation off the plates back into solution and that sulphation is caused by chronic undercharging, which the panels effectively prevent.
Thoughts?
