  Wiring Diagram
Note: The fuse or breaker used 
should be no larger than 30 amps 
The GP-PWM-30 is based on a 30 amp max 
input from the solar modules.  
E.G. Three modules in parallel with an input of 
7 amps each equal a total input of 21 amps. 
Most solar modules list the input amps on their 
specifications label.
