Example 2 - How to

 

connect 

5000VA

 model to PV panels with the following 

parameters?

 

•

P

max

: 250W

•

V

oc

: 36.6V

•

I

sc

: 8.75A

•

V

mp

: 30.96V

•

I

mp

: 8.07A

(1)

The max. PV input power for 5000VA model is 3750W,

3750W / 250W = 15

⇒

min. 15 PV panels shall be connected.

(2)

Best Operating Voltage Range is 70~120V,

120V/30.96V = 3.87 

⇒

 max. number of PV panel in series is 3.

(3)

Taking (1)~(2) into consideration, the optimized configuration is 3 PV panels
in series as a string, and 5 strings in parallel (as shown below).

(4)

Check again the V

oc

 and I

sc

 of PV string,

V

oc

 of string is 3 x 36.6V = 109.8V < 150V (Max. PV Input Voltage) 

⇒

 OK

I

sc

 of string is 5 x 8.75A = 43.75A < 50A (Max. PV Input Current) 

⇒

 OK
