How is the Time to Go (TTG) calculated
I have found that when the capacity is set to 200 A/H and I am drawing 20 amps I am seeing TTG as 5 hrs
What I have found so Far
The relay option has a SOC setting that is set at 50% and this setting seem to affect the TTG displayed. This seems a bit confusing as I dont use the relay option
The Alarm setting SOC does not seem to affect the TTG
You should be able to update it from the SOC relay (discharge floor) setting on the BMV or by using the Victron Connect app, under settings > relay > low SOC relay.
Hi; yes the discharge floor; which also affects the relay; is what the ttg counts down to.
Advantage is that you can configure till what point you want to discharge your battery.
Also if you do not use the relay.
mvader, I have 200 ah of lithium capacity connected to my BMV 712. Time to go is calculated to 50% SOC. How do I change the floor to 100%?
I have this same issue with a 600ah LiFePO4 bank - TTG is always 50% of my actual battery capacity, and then drops to 0% once I get below 50% SOC. Is there a way to adjust this on the BMV?
TTG is based off of the "Low SOC relay" which is set to 50% by default I think.
If you have Bluetooth you can go into the VictronConnect app, tap the cogwheel at the top right, tap into "Relay", tap "Low SOC Relay" and set "Set Value" to 0%.
The TTG will now give you the time for when your battery is completely drained instead of 50% as set before.
