3.19 PV Simulation
The PV array/module/cell is a device that converts from light energy to electric
energy. It is made by a simple semiconductor PN junction that the major output
characteristic is that there’s only one maximum power point (MPP) at certain
sunlight intensity. The PV inverter is designed to track this point to harvest maxi-
mum energy that is generated by the PV array. Therefore, all the PV inverters
have the maximum power point tracking (MPPT) mechanism built-in, and it is
very important to test the efficiency of this MPPT.

Editing Array VI Curve
A PV (photovoltaic) array simulator is built-in the PVS series power supply to
output the PV’s V/I (voltage/current) curve for PV inverter testing. User can set
up to 100 curves by 2 major parameters of the PV array (Pmp and Vmp) and
one 4096-point V/I table.
The menu as below:
PV-SIM PV Simulation
On/Off Enable/Disable the PV simulation function，Indicates to
enter the PV-SIM function mode and wait for the trigger to
run the currently selected PV curve file.
Vmax Used to limit the maximum value of the output voltage.
Even if the output voltage is set in the PV curve, the output
is still limited by the settings here.
Static Static PV curve setting.
Curve Open or edit a fixed format PV curve.
