Hi. I have a Phoenix Smart IP43 Charger 12|50 (1+1). Last night I wanted to charge my 400Ah battery bank, but since I was in no hurry, and that we wanted to reduce the noise from the charger, I decided to reduce the output Amps to 25 A.
The bank was quite empty (ca 300 Ah consumed since last charging). This morning I woke up, and there was an error message, and red light on the charger. I found out that there is a max duration of 10 hours of bulk charging on this charger.
Question: Is it possible to change this max time. Or alternatively; would it be possible to change this setting to a max Ah instead, so that slow charging (better for batteries) could easily be allowed?
Any ideas/opinions?
