I have a SPF 3000TL LVM-24P and 6 EG4-LifePower4 24V batteries and I've found that is you set the Growatt to Li (settings 5) then the it will only charge the battery bank at 50A. I would like to change this is close to 100A to fully utilize my solar panels. I need to change from Li to US2 in the Growatt and manually set the voltages. Here is what I've read are good settings but can anyone else confirm?

- from the manual / spec sheet for the batteries:

Charging Voltage (Bulk/Absorb) 28.1V (+/- 0.2V)
Float 27V (+/- 0.2V)
Low DC Cutoff 23.5-22V (depending on load - start high, lower if needed)

- You can probably still up the amperage to the batteries if you need to.
(at your current 90a / 6x batteries you are only charging at 15a)

Spec sheet says:
Charging Current Max Constant Charge: 100A (30-50A recommended).

post where Ben from SS says they charge EG4-LL at 40amps in their office:
