When I purchased the generator Cliff, I also bought a new gas furnace & on-demand water tank to get away from oil so all the prices are running together in my head right now, so I may be off on the price.
Here's the generator tucked nicely under the back deck
this is the transfer switch
And the 1500 litre propane tank
Before this unit I ran a 6500 watt portable that plugged straight into the house and as you say, their also a great unit and do a nice job, I just wanted to get away from having to be here to keep the gas tank topped up.
We lost power 2 years ago for 2 days and the portable cost me $100 in gas, but still better than the alternative.
