DESCRIPTION OF OPERATION 

 
AC Modules are connected internally to the direct current (“DC”) output of a photovoltaic 
module (“PV panel”).  They convert the DC into utility-ready alternating current (“AC”) suitable 
for connection to the commercial power grid.  In the event the utility power fails, the AC 
Modules will cease producing power as required by the UL 1741 Safety Standard.  When 
utility power is restored, AC Modules wait slightly more than five minutes as required by UL 
1741 before they commence generating power again. 
 
AC Modules operate totally independently of each other.  You may start with one AC Module, 
then add more to your system as time and budget allow. 
 
AC Modules are designed to connect to a 120V AC, 60 Hz dedicated branch circuit.  If 240V 
AC operation is desired, two separate “home run” cables and circuits are needed.  Connect 
equal numbers of AC Modules from Line 1 to Neutral, and from Line 2 to Neutral to maintain 
a balanced circuit.  You may start with just one AC Module connected L1-N.  For optimum 
circuit balance, the next AC Module should be connected L2-N. 
 
AC modules are more robust than standard DC solar panels.  AC modules eliminate most of 
the issues associated with ordin

ary DC “string” inverter systems: 

 

  AC modules are much easier to install. 

  Lower cost to install. 

  Far less prone to shading and other problems experienced by string inverter 

topologies. 

  No DC wiring calculations needed. 

  Eliminate all DC hardware (wiring, ce

ntral DC to AC inverters, DC disconnects…) 

 

 
WARRANTY 

 

Solar Warranty Periods: 

  25 year limited manufacturer warranty on Solar Module 

o

  10 years @ 90% power output 

o

  25 years @ 80%power output 

  20 year warranty on AC Module  

 
The  above  stated  warranty  does  not  apply  to  products  which  have  failed  due  to  improper 
installation, misuse, alteration, unauthorized repair or modification, or acts of God. 
 
Purchaser is responsible for transportation and handling costs of the equipment to and from 
the distributor or dealer for warranty replacement or repair. 
 
The  above  warranty  does  not  include  incidental  or  consequential  damages  and  PHONO 
SOLAR  disclaims  any  liability  for  any  such  damages.    All  implied  warranties,  if  any,  are 
limited  in  duration  to  the  above  stated  warranty  period.    Some  states  and  provinces  do  not 
allow  the  exclusion  or limitation of incidental or  consequential  damages  or  a  duration  for an 
implied warranty, so the above limitations may not apply to you.  All liability is limited to the 
original purchase price of the AC Module.
