![]() ![]() This is a number that you multiply the current out by (or I guess divide the current in) to allow for the inefficiencies in the battery. To determine the SOC (state of charge) is harder, you have to implement "Pukets Exponent" (sp?) which basically says you don't get out of a battery what you put in. That makes the problem really easy, get an ACS712 current monitor chip, or read across a shunt with something like an AD8210. You have a 230Ah bank, so I would say anything more than around 20A would be an issue. IIRC as a rule of thumb you charge wet cells at 10% of their AH rating, so for a 140A charging current you would need one heck of a battery bank. Hope someone can point me in a direction. battery health calculated from how much battery drains on a given consumption compared to a new battery bank.remaining time until empty battery based on "current" consumption.Realtime current charging (alternator, charger, solar panel).Realtime current consumption (broken down in some categories like lights, refrigerator, etc).Some features I would like the monitoring to have: ![]() I have 2 battery banks, 1 Start bank and 1 (2x115Ah) service/consumption bank that will deep cycle. I have 3 different chargers (alternator (140A), dual 220V (2x30A) charger and a solarpanel (<35W12V) charger). Does any one have experience with these kind of DC current sensors and can recommend some? (I need different sizes (5,10,30,150)).How can I make the sensor as accurate as possible? (I read someone had used a ADC converter to make the sensor more accurate). I want the current monitor to be as accurate as possible, but the current range from the alternator can be from 0-140A.What is the difference between AC and AC/DC sensors? Is it possible to convert a AC sensor to also work on DC?īy mistake I bought a few different sizes of sensors like SCT-013.I would like a non-invasive measure, so I would like to use "clamp-on" current sensors like the MT7191-ND The thread did not finish with good recommendations, so I post this. I found an article in the read-only forum regarding 12 Battery current monitoring.
