Looking for advice on how to add PV panels to my system. I know others have asked similar questions, but I'm still confused.
First some details.
Inverter EG4 6000ex (only one MPPT)
Max PV input 7500w
Max PV Open Voltage 500vdc
Max PV Input current 27a
PV Panels Sanyo HIP-200BA3 (20yrs old) 20 panels/4000watts (output is currently 3076w/242.6v/12.6a)
Pmax 200w
Vmp 55.8v
Imp 3.59a
Voc 68.7
Isc 3.83a
Running as 5s/4p strings for 279v/14.36A/4006.44w (via combiner box)
I want to add another 2kw to 3.5kw of PV panels to max the input on my inverter. I can't match the old panels (I've tried). Looking for suggestions/options for what I can do, without replacing the existing panels. I've found some other panels that might let me do this (REC TwinPeak 370w) but not sure if I can add 6-8 panels since the voltage and amps are different.
Any assistance or input would be greatly appreciated.
