Hello All
I am looking at starting my first off grid set up. This will be small at first as I get more gear and learn to get better setup.
My first project will be to run the check freezer we have on an inverter. Solar and MPPT batteries etc I am Ok with for now, but i need some advise on the inverter.
The freezer pulls around 200W normal use but this does not take into account the start up power, I also do not want an inverter on all the time the freezer is not running as this is waste of energy
So two questions
1, will a 1500 pure sine wave inverter cope ok starting a domestic 200W chest freezer.
2. If I put a relay on the 12v side controlled by a freezer thermostat so it switches on the inverter when the freezer needs to run will this burn out relay contacts with the inverter inrush current. Is this a bad idea as this will be large currents and could be large arcs, or is there a remote way to put the inverter to off when not needed I can do this by a relay
