I have a BMV 712 and am testing my battery bank. I have 4 6v 230ah wire in series parallel for 460ah. I used a 1000W inverter to run a hair dryer which was pushing 600 watts which if my math is correct should be 5amps. The BMV was reading 50 amp out going this seems really wrong. am i missing something or is something really wrong
i may have figured it out. i did not figure watts for the 12v even though its being inverted im guessing the 600w load is ultimately going through the batteries which would put a 50 amp dc load on the battery not the 5 amp ac load that is calculated at the inverter. If someone knows that im on the right track please let me know
That's correct Joseph,
I would really encourage you to do the Victron Online Training on Batteries and Battery Monitoring - you will need to create a free Victron Professional account.
That explains this, and many other useful similar things that need to be considered and understood:

Chapter 4 - Batteries and heat
Chapter 5 - Batteries not in use
Chapter 6 - Correct charging of batteries
Chapter 7 - Battery bank configuration and set up
Chapter 8 - Battery monitoring with Voltage
Chapter 9 - Battery monitoring with State of Charge (SoC)
