I know nothing about the King II models, but F80 suggests a problem with the parallel boards or their cables. [ Edit: But see next post for a firmware fix. ]
The King IIs are relatively recent models, so they might have firmware teething problems. There was a recent report of a clock drift that was fixed by a firmware update, I believe. So perhaps ask your supplier if there is an update available. The latest I have is 50.09 from June this year.

hi 
i have bms seplos and i tried to contact bms with my inverter expert king ll (parallel opertion) through pylontech protocol and i connect with communication wire with master inverter and both inverter battery icon flashing but the second inverter still with led flashing and error 61 but it works and battery flashing but in same there is error 61 and red flashing so anyone can know why this happened or I need canhub or something or program issues?

Hi, 
I found MPPT never dip when power output of inverter above Or below from maximum power output available in solar array but when load of inverter equals to maximum power PV available here Mppt becomes disconnect and returns doing that until you make your load below Or above Mppt power available from solar array.

This link the new update .50.09

That might be a firmware issue. What main (U1) firmware are you running?
