Hi
I’d like to find an answer to the following issue.
I’ve been receiving low-battery alarms for weeks. After my failed, but corrected, firmware update on the MP 48/10000/140-100 yesterday, the system is working properly again.
This morning, there was no alarm, but the following: The mains on, inverter on, and bulk LEDs are lit continuously. The low-battery LED is flashing. After taking some power (making coffee) the low battery Led was off, but after some time it’s blinking again. The Victron toolkit says this combination doesn’t exist. Does anyone have any idea what this could be?
Now the system is in the bulk charge mode and only the mains on and bulk leds are lit so normal state.
Thanks in advance for your help.
The LED combination shown looks like a warning state in ess mode.
Inverter is in pass thru / charging mode with low battery condition (mains, bulk and invert leds on), BUT not charging the battery significantly. ESS mode, if both invert and mains on are lit, indicates minimal power flow through the system.
If the battery is low warning (flashing rather than steady), then there may be some limit in the DVCC stopping charging.
Thanks for your reply Mike.
Yes it seems a low battery warning. I didn’t activate the DVCC function. The ESS is configured for Optimized (without Batterylife) and for self consumption.
In the battery BMS is everything ok when this warning appears, no voltage drop, no imbalance. In the days before I’ve got a lot of “low battery alarms” and the BMS showed the message “total voltage fault” and then disconnects the battery from the inverter.
Now the inverter falls in Sustain with the SOC of 29%. and takes energy from the grid.The battery is in the idle state.
I’m just busy to start a new topic for this strange behaviour.
