I am considering automatic inverter pre-charge in my RV.
My inverter is eating over 30W with no load so its necessary to keep it off.
I would explain my motivation and goal with this example of using induction hob:
1) user pushes special button to turn the induction hob on,
2) ESP turns on the inverter using automatic pre-charge,
3) ESP turns on the induction hob,
4) when amp meter on the output of inverter notices that there is no load on the inverter, after some time delay ESP turns the inverter off.
I would prefer to include automatic pre-charge, but I dont know about any usable big relay with minimal resistance which could handle continuous 135A.
Would you know about such "super relay" which could be used like this?
Or do you have any ideas around this automatic pre-charge idea/setup?
