Hello
I need help to figure out why I keep getting low battery warning on my Multiplus II, when the EG4 has dipped slightly below 100% SOC?
If any one is using the Signature Solor EG4 Battery 48/100ah with the Multiplus II, and the system is fine. Would you share your VE Configure 3 Settings.
Do you have any assistants enabled?
Do you have the EG4 BMS controlling an attached GX device?
If "YES" to either, please elaborate.
If "NO" to both:
General:
These depend on your AC input options/limits.
Dynamic current limiter enabled.
Inverter:
Set shutdown to 43.2V (2.7V/cell). The others should auto-populate.
Charger:
Absorption:
55.2V with 2 hour absorption OR
56.8V with 1 hour absorption
Float: 54V
Repeated absorption interval: set to max allowed.
Charge current: limit based on available input and # of batteries. 20A/battery is a very conservative value. 40A/max is recommended max, though they can safely take more.
I did a recommended update to the Multiplus firmware and the issue has gone. My system is now performing like a champ.
A firmware update wipes existing settings. It's probably worth reviewing them to make sure they're good.
