where N is the number of units in parallel. Please note
as more units are paralleled and linked together, speed
will become slower. Thus, we do not recommend
paralleling too many units with this setup to ensure fast
performance and operation.
If the application requires connecting more than 10 units
in parallel operation, we advise to contact us at

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
effectiveness of the inverter’s MPPT algorithm.
