Sunsynk settings not locking
Hi everyone. I have a site with 5x 12kw sunsynk inverters with 8x 14.3kwh solarmd batteries, all in parallel. The issue I am facing is the master is not retaining set parameters e.g. it keeps reverting back to AGM V on battery type from the set Lithium option. Time of Use settings hold for less than 2 min and revert back to default settings. Can anyone kindly assist?

Managed to get it right by bringing in the slaves one at a time until all synced well. Very strange...
