Please can somebody help to send me the best settings from 2 Axpert inverters running firmware 72.30

after starting the 2 inverter i get error 60 and in the info log from ICC it sates negative power detected fron 2nd inverter

only the master Axpert has PV which is 4200KW of panels i am not even getting closs to 3000

please need help with the best settings or how to eradicate the fault

thanks

I assume you mean 2 x PIP-5048MS inverters, equivalent to Axpert MKS 5K-48.

Are you using parallel boards?

Both inverters are in PAL output mode (setting 28)?

I assume you mean 4200 W nominal of panels. How many cells per panel, or what is the Voc?

How many are you wiring in series?

See my signature for how I feel about 3S of 72-cell panels on inverter-chargers (like the PIP-5048MS) that have 145 V absolute maximum PV voltage.

Thanks coulomb, it was a typo, i meant 2x PIP 5048MS inverter i have 15x 280 3S5P 60 cells panels
