Updated to the latest Multiplus firmware 502

Hi all

I have an EasySolar II 3000/35 and it was working fine on firmware 501 (on Multi) and since the upgrade to 502, had issues ever since. I've successfully updated the firmware on all the components hanging of the GX controller (MPPT, GX controller & Mutli). Tried flushing the configuration by loading the default config and used a fresh version of 502 to no avail. As soon as I load the assistant, then the errors start (VE Bus errors # 6 & #15). Running on a backup Multi (502) in the interim and the backup Mutli & Easysolar share the battery in the interim. Does anyone have copy of the older firmware (2629501)?

Resolved problem - had to remove ESS, set grid code to none, update setting and THEN reinstall/reconfigure ESS.
