Growatt 3K - BigBattery LLAMA settings

[rjpear]

Hi folks, I received the following info from BigBattery and thought I would post it in case someone is looking in this direction. This is from the 48V Off Grid System they packaged together over the past few months (

FLAMA-48053-G1	48V LAMA - LiFePO4-115Ah-5.3kWh	1​
SPF-3000TL-48P	Growatt Solar Inverter SPF 3000TL LVM 48P

The number is the MENU SETTING in GROWATT #:

05=USE
12=44V
13=48V
19=50.4V
20=50V
21=42V

Low voltage cutoff around 3V/cell works well for lifepo4. Bulk charge voltage at 3.425-3.5V and float 3.35-3.4V are typical ranges.

I'll give yours a try to see if they behave differently.

The numbers they give are for absolute maximum capacity
