Warning! 

 

  Please do not connect PV array positive or 

negative to ground, it could cause serious damage 
to the inverter. 

  PV module used with inverter must have an IEC 

61730 Class A rating. 

 

 

Warning! 

• Ensure that input DC voltage is less than max. DC 

voltage. 

• Over voltage may cause permanent damage to 

inverter or other losses, which will not be included in 
warranty!  

 

 

Warning! 

• Authorized service personnel must disconnect both 

AC and DC power from the ST series inverter before 
attempting any maintenance or cleaning or working on 
any circuits connected to the ST series inverter.

 

 

 

Caution! 

• The photovoltaic array is exposed to light, it supplies 

a dc voltage to the inverter.
