FoxESS Community - Owners & Installers Forum

I have just discovered my batteries have different version number, please see screen dump attached.
Should i ask the installer to update or is this nothing to worry about?

At a minimum all the slaves should be the same version, but actually they are really old firmware versions, I would recommend you ask your installer or raise a ticket along with your inverter serial number to FoxESS and get them updated - later versions have improved capacity, temperature handling and SoC stability.

Current Mira Versions are :-

1.011 for Master (BCU) and 1.09 for Slave (BMU)

Thank you Dave,

I have contacted the installer, I will give them a week to update and raise a ticket if they dont do it.

Please let know if you see any improvements when the firmware is updated. I'm running 5x HV25s like yourself and am also on master 1.004 and have 4 batteries on 1.00 and one on 1.001.

Will do

I've just been updated to the latest versions today which are now 1.013 Master and 1.10 slave. I'll report if I see any improvement!
