A friend recently purchased a V-TAC VT48100 LiFePO4 battery, but we discovered that it might not be compatible with the Growatt SPH 3000TL-BL-UP inverter. I'm wondering if it's possible to use this battery in Lead-acid/User mode with this inverter. If it is, what basic settings should we set up? Also, do we need to use an NTC probe? Thanks for any help!

You can use that LiFePO4 battery by just controlling the voltage, so it should work fine! Most inverters have a setting called lead acid that you can use. Since you’re dealing with a 16s battery, set it to about 56V for bulk/absorb and 54V for float. Just keep in mind that communication features might not work, but voltage control should be okay.
Exactly! As for the NTC probe, it's usually needed for proper temperature management, but if you're having trouble locating one, focusing on voltage should still allow you to make it work.
