Inverter prices are going up at Can Tire so you have to grab the sales when you can. EG, last year the 1000w PSW was about $160 on sale but latest was $199 on sale. The 3000w MSW was $169 last summer on sale but now is $219 on sale this week only until who knows when for how much?
I have been using a 2000w MSW to run the microwave etc. and a smaller inverter for the TV etc. But now need a second big one for another RV. I am likely to grab that 3000w unit this week while I can, even though I only need a 2000w, the way things are going.
Last summer a guy camping nearby had one of those 3000w jobs and I liked it a lot. He was running his MW etc on two 6s, but he also had some solar to get back up to speed with. Without the solar IMO he would have needed four 6s so he could run things when below 75% SOC.
Anyway you have to watch those sales that rotate through their various sized inverters every few months. Never buy one at the "regular" price!
I use the shore cord into the inverter trick so can't suggest anything about transfer switches, etc. Way too complicated for me! This way, I can just grab something on sale and am good to go :)
