Title: MN3024diy-- battery bank size
Post by: Hazzard34 on December 11, 2021, 04:15:56 PM
I have MN3024diy installed with 2 12volt renogy 200 amp/hr batteries in a series...starting with a full charge and a 6 amp draw, the battery status bars drop 25% every 6 min....so at 12 min of use at 6 amp draw, status bar says 50% used... If I have4800watts, 2400 watts usable, how is a 6 amp draw,(6*24=144watts), draining my bank so quick?

I am not familiar with the MN3024.
But in general a battery SOC is just an estimate.
There is probably somewhere in the settings you need to calibrate the SOC meter by entering the battery capacity.
Your battery capacity would be 200ah  at 24v .
It would be good to have a digital volt meter , ideally a DC clamp meter so you can check your system for voltage and current.
You can get inexpensive clamp meters - I have one of these https://www.ebay.com/itm/324455330164?epid=2254828348&hash=item4b8b0b7174:g:IzsAAOSwAy9dTPnn
That way you can check your system to confirm and troubleshoot.

What is the voltage drop measured at that time ?

Or is that the 6% ?

Recognition?hmm.
Might want to check the battery it self if it has an issue.
