[pdf] A Power Conversion System (PCS), often called a hybrid inverter in a Battery Energy Storage System (BESS), is a key component that manages the flow of electrical energy between the battery storage and the electric grid or load.
[pdf] Our batteries cannot be connected in series to make the battery system more than 48V. A 12V battery in series supports up to 4 batteries (12*4=48V). 24V batteries in series support up to 2 (24*2=48V). 36V/48V batteries do not support series connection. So pls do not connect 2*36V batteries in series.
