January 21, 20197 yr Hello guys The time to go on the Pylontech battery on the Venus is never calculated, even when I remove the AC, anyone have any ideas?

Because that isn't done by Venus, it is done by some battery monitors (the BMV and I think some of the VE.Can batteries). If the battery doesn't publish that information, it doesn't show up on Venus.

Well that kind of sucks, I don't really want to add a Victron BMV just for the luxury of getting a time-to-go value :/ But that's Pylontech's fault and not Victron's, I guess I could always try to find a cheap secondhand BMV700 to give me the T-T-G value.

It's a bit like the distance to empty thing in your car though. It takes one estimate (liters in the tank) and divide it by another (fuel consumption), and then come up with a number. It cannot know that there's a nice twisty road ahead and I'm absolutely going to slingshot through all of them... 🙂 I sometimes mentally calculate time to go. I have 300Ah batteries, so every 30Ah is 10%. So take amp reading on the screen (I prefer the tile view over the balls view), say it is 20A (500W on a 24V system), that's 1.5 hours for every 10%.So 50% battery gets me 7.5 hours. All mental math... 🙂
