Grid Off Standalone wind-solar hybrid battery charging system
I am interested in understanding the behavior of my little 2kW wind and 900W solar PV system for charging double string of 48V Battery Bank!
firstly, I am curious weather there is a formula to calculate the battery capacity of a specific system despite the end-load size.
secondly, my wind turbine is 2kW and it never gives even 1.5 kW! I think this is due to the size of battery, I believe it would give more power if I add more batteries in parallel to maximize the charging current from the PMSG used in the WEC system.
looking forward seeing from you experts.
