Just wanna ping the forum to see what you think and any guidance.
In this scenario, I have an EG4 6000 EX which has the following PV limits.
Watts: 7500
Volts: 500
Amps: 27
Mppt: qty 1
Panels: Sunpower 305 Watt Solar Panel Model: SPR-305EL-WHT-D
Voc 64.2
imp 5.58
My basic calculation (not accounting for all parameters) shows a 7s3p would be the maximum for this combination of panels and inverter.
each string would be 449.4v at 5.58 amps for a combined output of 449.4v at 16.74 amps.
My question is; 21 panels at 305 stated watts a panel = 6405w. But if I use the formula "volts * amps = watts" (449.4 x 16.74) = 7522w, which is higher than the specified 7500 for the inverter.
Which value do you use and or what would be, if possible, a better configuration of these 305w panels to maximize the PV production on this EG4 6000 EX. I'm also looking for anything I'm overlooking, please critique my work!
Thank you in advance!
