Solar simulator and network test equipment

Ding's latest PVA series of programmable analog power solar cells, the use of a new type of insulated gate bipolar power transistor soft-switch technology and low-loss rectifier technology, the output voltage over a wide power range up to 95% power efficiency; provide single module can simulate solar maximum open circuit voltage (Voc) of 1000V and short circuit current (Isc) of 40A (9U), and has a fast response, good dynamic characteristics; widely used in photovoltaic inverter and grid-connected inverter production, testing, aging, analog maximum power point tracking (MPPT) performance testing; built after single solar cell as a function of the mathematical model, the user can simply set the single front panel of the solar cell IV characteristic (Voc / Isc) an analog output IV curve of the solar cell array to the PV inverter test static MPPT performance.
