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
