I am using the VictronConnect app (Android) to connect with my BMV-712. The app show 265W of usage (consistent over the last hour), but the "Time Remaining" is estimated at only 4.5 hours. The battery is 24V and 233AH with a current state of charge of 80%.
The estimated time remaining seems VERY low. Any ideas?
The BMV estimates 'time to go' in relation to the discharge floor SOC%. This parameter is actually in the relay settings and has a dual purpose.
So if this is set at 50% SOC and you are already at 80%, then it's only calculating time to go over 30% battery capacity.
The discharge current will also have an effect, if it's higher than the C20 discharge current for your battery bank then the battery will provide less than the C20 rated capacity and the BMV will estimate a shorter time to go accordingly.
Both of my values are currently set to 20%. Please explain "relay handling" if I set mine to 50% and 90% as in your example. TIA.
Sounds about right if you've set your max DOD to 60% ish.
