I have setup 2 Multiplus 2 48/5000 in parallel.
All wiring DC and AC are identical is size, length and quality.
At loads of 5000w I see an imbalance between DC cables from Lynx to both Multiplus of 0,5A.
Is this acceptable?

Parallel Multiplus2, imbalance DC
Yes, they will never be perfectly symmetrical. A deviance of a few percent is perfectly ok.
Thanks for your reply.
I can't stand deviance but I guess I better put the amp clamp away then haha.
I must say that after running both Multi's in serie for a year, parallel is so much better. Visiblity in VRM improved massively. Should have done this since the beginning.
Not under full load, 5kW of 8kW available. Will ramp up the loads tomorrow to it's limits and check deviance again.
The only difference in the system are the connection points on the Lynx, one Multi is just a notch close to battery than the other.
I've did my outmost best to have perfectly matching cables and connections.
As long as the imbalance doesn't get large enough to cause one inverter to go into overload prematurely and there's no indication of a bad connection or something getting hot, I wouldn't worry about it. For the amount of power you're drawing, 0.5 amps is a pretty small difference and nothing to worry about.
