In PVsyst, is there a set up to charge BESS first and then discharge the energy into the grid at night such as 7 to 11PM?
My utility solar project is 600MWdc and 450MWac at POI. We considered the 264MW x 4hours system using Sungrow ST5015UX-4H-US. When I used Peak Shaving mode, it only charged the extra energy over the POI limit, so once I see the result, it shows only 1.5% of energy was stored during a year.
Our goal of the design is charging the energy into BESS during a day and then discharging it after 7PM for 4 hours.
Can you give me advice? Also please let me know if PVsyst can support DC or AC coupling separately.
Thank you.
