EasySolar firmware update?

I have the EasySolar 48/3000/35-50 mppt150/70 with 4 12.8V Lithium (LiFePO4) batteries connected in series. All works fine, but the CCGX don't display SOC. I guess this might be firmware related, but I'm new to Victron products. The multiplus inside the EasySolar has firmware version 413, the MPTT runs on v1.39 and the CCGX on 2.23. Should I update the Multiplus? Greatful for any guidance here, thx :)

Update May 13: Took some time to finish this, but today I finally got firmware version 459 installed on my Multiplus, and the battery monitor set-up as Mark pointed out. All good now, the CCGX shows SOC as expected :-) Thanks everybody!

Dear Thorleif,

I am going to do the same upadte from 413 to 459 for my EasySolar 48/3000/35-50 with VEFlash since VictronConnect is not possible... Were the settings afterwards easy to import? Any difficuties or problems during installation or however anything to be mentioned from your side so far?

THX Jean (enduser ;-)

Hi Jean,

I performed the upgrade before any configuration had been done (since the EasySolar was brand new), so I never needed to export/import the settings. But the upgrade itself was quite easy, I encountered no problems whatsoever. It took just a couple of minutes, actually.

Hopefully you won't experience any problems either :-)

My EasySolar is running 2620158. I'm hoping I can add a Grid Tie inverter w/extra Solar strings attached. Anyone know if this model can do it? Will I need to update firmware?? TIA

You should always update the multiplus to latest firmware to get new features and assistants. Latest firmware currently at version 433.

Secondly you need to configure the multi the correct charger settings and assistants for lithium batteries

By the way, 459 is the latest firmware and supercedes 433.

Firmware version 459 is intended for the new multiplus II.

I believe that the main reason SOC % is not showing on the CCGX is because the battery monitor functionality in the Multiplus has not been set-up.

See link to similar issue & answer;

By all means still update the firmware.

Thanks for your help, that probably explains it. I assumed the EasySolar was already set-up, but it's probably not. Just got my MK3 - USB Interface in the mail, so I will check the configuration and update the firmware.

All good - happy configuring...

It could not be fully setup out of the box as it would not know your battery bank capacity, and that directly effects the SOC % calculation.
