Switching to battery power

pauly, I'm left wondering why a generator that produces a pure sign wave is an advantage? The Strom and the Milwaukee both produce a pure sign wave so I was thinking that the Milwaukee would be the best option. However my electricity at home doesn't produce any type of sound wave that I'm aware of. Also, you might consider the wattage of the unit and the possibility of the generator over heating. 
The EGO has a good price tag. It doesn't include the batteries. Four of those may end up costing you about $300.00. Which ever generator you buy, please let us know what you think.

Starting later this month I will be living off the grid until September.  I have excepted a "Caretaker" position for a Battery/Solar power cabin in the mountains. I'm taking my bedroom system,  Spica TC 50 speakers and a newer Pioneer VSX-522 receiver.  The front end will be either Phone or Computer and if power turns out not to be an issue. I will take up my SL-10 TT and JD-9 pre. I'll report back.

Our AC mains is a 50Hz - 60Hz sine wave, so that's why the battery power stations are made to create them - to match the mains power.

If you feed your electronics a square wave or modified sign wave you may damage them. And if you don't, I'm sure your sound quality would be terrible. So a "pure wave" power station is the way to go.

Question is, just how pure is the pure wave? None of the battery power stations manufacturers publish that, so I'm going to have to roll the dice on that one.

To your point re wattage, I want at least 3 - 4 times higher continuous power output from the battery power plant than what my equipment will draw. 

pauly, please let us know how the EGO sounds.

My Zyx Artisan phono stage is battery-powered and hard to beat in terms of S/N ratio and speed. As pointed out above it makes most sense where small amounts of DC power are needed. 

That said anyone converting a whole system with a Tesla power cell pls report on your experience
