Is there a secret potentiometer for adjusting the charge current on a Quattro?
I have never been able to get our Quattro 24/8000/200-2x100 (230v) to charge with more than 160-165A, not the published 200A spec.
I always assumed it was our FLA bank or bussbars / connectors, but now with a new LFP bank, Lynx bussbars and new cables (2 x 2m pairs 70mm2) it's still not able to go above 160ish Amps.
This is charging from a single phase of a fairly balanced Perkins 57kVa 3 phase Stamford generator, 32-45A input limit for Quattro. Good stable 50Hz frequency, but 220v (It can do 73A per phase max) I did try adjusting it to 230V but then it's 53Hz. Either way, it was still only 160A Charge output.
SmartShunt for overall current Monitor
DVCC: 510A Limit charge current
BMS's are calling for full 170A each x 3
Weak AC is off
Dynamic current limiter off
This has been ongoing for 2-3 years, with the old batteries, many Venus updates, settings changes, GUI mods, the only constants are the Quattro, and the generator.
I don't have a scope to check the genny, but I think it should be fine.
Any thoughts?
