Eg4 float voltage question

Mannfamilywoodworks · Sep 4, 2022

Hello. This may be a silly question but I noticed float voltage is set at 54.0v by default with my growatt 6k AIO inverter.
It is setable.
I’m wondering if I should change this setting?
Eg4 batteries spec sheet states 56.5v.

I would raise it to at least 55v. So that the BMS can top balance better.

I just stumbled upon this.
55v would bring me to about %99 SOC

should I not worry about that %1

The other question I have if you could help is setting 12 and 13 on the growatt 6k AIO

My previous settings were %30 and %100
Should I change this to say %25 and %99

56,5v is also fine. And recommended by the battery manufacturer. I was just giving a more conservative option. The difference between the two will be a very small amount of energy.

Awesome Thankyou for a quick confirmation.
I’m going to change it to 55v now.

#12 should be set for how much reserve you want to always have.
#13 should be set for when the solar can cover your loads and also charge your battery. Without switching back and forth a lot.
I have mine set at 20% and 40%.
