Hey everyone! I just finished setting up my budget DIY solar system and I'm looking for some advice on the battery settings. Here's what I have:
- **Inverter**: Anern evo 10.2kw Hybrid
- **Battery**: Solarhomes 51.2v 300ah
- Specifications: 51.2v nominal, 300ah capacity, 15360wh total energy
- Charging voltage: 58.4v
- Max charging current: 120A
- Max discharge current: 200A
- **Panels**: 10 x 550W panels
I'm having trouble getting my inverter to communicate with the battery. I've set the following parameters:
- Max charge current: 50A
- Bulk charging: 54.4V
- Floating charge: 54V
- Low DC cutoff: 48V
Do you think my settings are adequate or am I over/under setting anything? Any input would be really appreciated, thanks!

I charge my batteries to 56V with a float at 53.6V. You're right about 54.4V being the minimum you want to hit, but I’d recommend bumping your bulk charging up to at least 55.2V for better performance.
That's for the bulk charging, right? At 55.2V?
