Need help with 240v DC current sensing circuit

i have a small workshop that's very remote (no grid power) so i use 20x12v 63ah battery setup that runs my workshop air compressor (brushed) and would like to build an circuit to start my 500w generator automatically, the generator just needs 2 wires kept bridged and it will self start and continue to run, im just after a simple small circuit to bridge 2 wires together when load is applied and continue to run for about an hour after no load is applied to give the batteries a good charge.

here is my proposed concept, sorry for the terrible paint drawing.concept11111111.jpg
