We have a new set-up (<3 weeks) with two Quattro 8000/200/100/100 24v 230 set-up to run in parallel linked to CCGX and Lynx BMS Control for MG Energy LFP batteries. Both units have been upgraded with v465. CCGX is upgraded to latest release.
Since day one we have spurious L1 Overload on Master Unit and usually concurrent to the event a load buzzing and the Slave unit is appears to be OFF with no fault when fault appear. No overload warning. All the incidents happened in light or no load conditions.
We have witnessed one incident with no load connected to the output of the quattros. The two outputs were cross connected at the time of the incident. We measured current spike between the two unit when this happened. It would seem that either the units are getting out of sync or one of the two unit is short circuiting causing the other unit to overload.
We have replaced the cross connecting Ethernet cable with brand new patch cable with no appreciable improvement.
Any Ideas, suggestions ?
