This is supposedly a less expensive alternative to the Tesla Powerwall:OrisonStill too much money for RVers, but the price of energy storage is slowly getting lower.

Interesting. They have the right idea, keep it simple.I like the idea of refrigerators having their backup power supply.I'm sure we will see that in the future, when the price drops.

2000w per 18 kg huh? So that's 111 watts per kilogram. Less than half a low end lithium cell (250-350w/kg). I wonder why their numbers are so poor, lots of safety equipment increasing the weight?

I get 1.6 kwh on a Honda Eu2000i, gas is cheap, and I already own it as back up for the refrigerator, if there's a power outage.I am certain the product is useful, once the price per kwh comes way, way down. It's just difficult, when so much energy is stored in a gallon of diesel fuel or gasoline.

Likewise once you have solar on the roof it will be ready for when the weather clears.
Even one or two hours a day can make a big difference.

The weather usually clears at some point, but the people are not there to take advantage of it. SOME eventually come back.. But most do not, and those that come back have missed some of the best hunting.

Oh, sure!

Solar is nice when the weather is nice.
A tent or even just a cot will do just fine when the weather is nice.

A generator can power my TT when the weather is nasty. And that is when I need both of them. and why I have both of them.

Unlike many here, I rarely camp just to camp.
My trips have a purpose. Usually either a hunt, or a dog trial, both of which have set dates, and take place no matter what the weather is.

Calculation of break even is not just the initial purchase as the running costs of solar are a bit lower.

And yes solar has cloudy days and you need to run out and get gas for your Honda.

I will end with people are getting ahead with installing solar at home and no one is running a back-up generator because it is lower cost than utility power.

I wasn't aware solar had matched the $ / watt / kg ratio of gasoline yet?

Can solar charge a battery, sure, eventually... point me at a solar system that will charge a battery bank faster than a hydrocarbon powered generator, while maintaining the same watts / dollar ratio ($1000 dollars, 1500 watts for example to match the Honda 2000)
