While in parallel connection mode, the output voltage of 
each power supply should be set to equal value. If the 
voltage value of each unit is not the same, the higher 
output voltage will feed back to the lower voltage unit 
and damage its internal components. 
Do not connect multiple power supplies in series as it 
may cause damage or malfunction. 
3.7  PV Simulation 
Typically, a solar array is connected to an inverter, which converts the 
panel’s output from DC to AC. Due to varying environmental conditions 
and the nonlinear output of solar cells, many inverters use a maximum 
power point tracking mechanism to maximize the power generated 
from the solar panel. Using an actual solar array to test inverters is not 
cost-effective and environmental conditions are difficult to control in 
this scenario.  
The PVS power supply can simulate the output of a solar array with its 
solar array simulator (SAS) function. Combined with the PVS SAS 
application software, users can simulate the I-V curve of different arrays 
under various irradiance conditions while measuring and validating the
