Could anybody please explain what the advanced setting "Battery target" does?

Could anybody please explain what the advanced setting "Battery target" does?
And in which situation should it be used? I have some ideas, but it easier to ask than reverse engineering it.
Thanks in advance.

That came out strange. Sorry.

Yes I'd like to know too please

No worries - there's a discussion about it here, which includes formulas too. In short, it's a correction factor to allow you to tweak the calculation of the target battery percentage.

admin Thank You, that was what I guessed. Maybe "target percentage" could be in the description.

I am not getting 100% on batteries when smartcharge calculates 100%. More like 90-95%.
When smartcharge says 50%, I get 50%. I have been tweaking my settings (raised battery capacity), and it helped. Maybe it is Growatt throttling down when SOC get over 85% ?

All in all I am very pleased with WW performance.

Not sure I still quite understand from that thread. In agile I’m finding WW charges my battery to 98% rather than 100%. Does this setting mean I can adjust the target to get it to reach 100%? Conversely if I wanted to only charge to say 75% on agile do I use this setting too?

Capt_Rich No, this setting is not being used for Agile Octo at all.

We do send a 100% target instruction for Agile (for now). There could be plenty of reasons why the battery doesn't reach it, especially when it is close to 100%, as the BMS reduces the charge rate automatically.

That's not anything that WW has control over.

Ok thanks.
