Hi Guys/Gals,
Can anybody give me a range of DC bus capacitances (between DC+ and DC- of inverter input) on large, 250-500 kW PV inverters? I am interested in the following configurations:
- Grounded, isolated inverters
- Ungrounded, isolated inverters
- Ungrounded, non-isolated inverters
Bonus points if you can send me a link to a product that is used in such an inverter. I was looking at Vishay low ESR capacitors, but they only go up to 470 uF, which feels low...
Motive: I am trying to understand charge/discharge phenomena of PV inverters and, as I am not an employee of an inverter company, I am finding it a little difficult to obtain realistic capacitance values.
Any help you can offer is really appreciated. :thumbsup:
Thanks,
Dave
