EG4 6500EX F08 Error

Thanks for the information. I have updated the firmware and set 34 to enabled. The problem seems to have gone away.

That's great to hear!

Not what I expected to resolve the issue, but if the error went away, then that's what matters!

Good call on updating the firmware.

If you need anything else, let me know!

@BenFromSignatureSolar Could uneven lengths of battery cables cause error 08? My + and - battery cables were previously inconsistent lengths, and I noticed the load numbers on the inverter did not make sense, as well as getting Error 08 when charging the battery from grid power.

I cannot say for certain making the + and - battery cables as close to the same length as possible fixed everything, but I can say that after I made the battery cable length equal, my load numbers have been accurate, and I've received no more Error 08.

No solar panels are connected to my system yet.

FYI, all the positives, from the inverters to bus bar should be the same length, and all positives from bus bar to battery modules need to be the same length, and same rule for negatives from inverters to bus bar and from bus bar to battery modules.

But positive side and negative side lengths to not need to match each other. Only the paralleled lengths in the circuit...

Thanks for the information. Here's how I setup my 2 18KPV battery cables. All cables are matching lengths.

What brand bus bars are those? Are they the ones saw on Signature Solar's website which are currently out of stock? I've searched everywhere and I can not find anyone selling anything like them. I even checked AliExpress.

Those are SS busbars.

Hi Ben can you please send me a copy of the trouble shooting for F08, I'm having the same issue on two 11kW Max II. I've contacted the manufacturer but they've not been much help. At first the SL unit had F08 after functioning fine for several hours, then both ended up with F08. I've rewired them out of parallel and connected up but still F08 persists. I have one spare inverter I will install to see if it also gets the same error.
