Hi all, I have 2 Axpert MKS 5kw inverters connected in parallel. I want to add a 3'rd one, but can not find one. Can I connect it with the MKS-II ?

No you generally cannot parallel an existing Axpert MKS 5 kW inverter with an Axpert MKS-II 5 kW inverter.

They’re different models/firmware generations, and for stable parallel operation Voltronic/RCT-style inverters need to be the same model and very similar firmware so they can communicate phase, current share and master/slave roles correctly. Mixing an MKS with an MKS-II is not supported and is likely to cause errors, sync problems or faults.

I yave one of these from voltex if it helps you

@Shockin @Oros That will work nicely👏 just ensure identical firmware.

@Shockin what price are you looking for?

Hi make an offer, have a separate screen for it and the axpert db board complete for it

Is it in working condition?

Sorry, what do you mean by Axpert db board?

Was working perfectly when I replaced it with a solis 8kw last year

I offer R7000, if you can hold it till 25 January. I get a small bonus then.

You can take it all for R3000

Perfect thank you very much!!!
