Chroma provides PV inverter testing sol utions based on its thirty years of
experience in power electronics testing. These solutions include:
1 . DC Power Supply 62000H-S Series : to simulate output characteristics of
the solar array. It also provides a unique feature called solar array simulation
function. This function is useful for MPPT performance evaluation on PV
inverter devices.
2. Di g i ta l Power M eter 66200 S eri es : to m ea su re PV i n verter ou tpu t
parameters, such as V, I, P, PF, current harmonics & THD.
3. AC Power Sou rce 6500/61 500/61 800 Seri es : to si m u l ate m a i n s power
various scenarios.
4. AC Loa d 63800 S eri es : to si n k cu rren t d i rectl y for off g ri d type PV
inverters. The Chroma AC Source provides a voltage level as the reference
for the PV inverter output. But the AC source can not sink current (energy);
therefore, an external resistor is necessary for load simulation. Chroma also
provides Automated Test Systems suitable for R&D, QA qualification and mass
production.
