Answer Posted / k.prakashchandra
Is it correct that batteries are connected in series ? The stored energy in each battery is 12 x 100 = 1200 Wh. Total = 36000Wh . The load in watts = 230 x 15 = 3500W ( app ) . Back up = 36000/ 3500 = 10 hr(app)

This is reqd for a 1MW Solar power plant..We have 2DC outputs from the solar panels Connected to 2INVERTOR panels.. Output from invertor is 3ph,280v,500kva,50hz.These are connected to individual ACB.This has to be stepped up to 11KV ,1250KVA SYSTEM.Now can I use (1) one more ACBTO GIVE A COMBINED OUTPUT OF 1000KVA,280V & STEP UP THE OUTPUT BY USING a single two winding 3 ph transformer 11kv/1250kva. or (2)use the two outputs and connect to one three winding transformer of above rating..Pls suggestwith details.
