13.F.A.Q. 

• About solar panels, what’s the maximum voltage 

supported by 

SUN

CONTROL

2

? 

Maximum supported voltage is 29,5V.  

• Is  it  possible  to  connect  one  200W  solar  panel 

only, on a single 

SUN

CONTROL

2

 connection?  

It’s  possible  to  connect  just  one  bigger  solar  panel 

(200W), for example on 

SUN

CONTROL

2

 Pin N°5, but 

you must connect Pin N°5 and Pin N°6.  

For  the  connection  bridge,  please  use,  at  least,  a  6 

mm

2 

cross-size

 

cable. 

• Is  it  normal  to  have  a  battery  voltage  (with  solar 

regulator working) over 15V? 

It’s normal when the device is in desulphation mode. 

It is possible to turn OFF the desulphation selecting 

the  proper  charging  curve:  look  at  the  chapter  

“Charging curve selection”.
