> Scrolled further to discover the team has "talented people"

One of their "brilliant" "talented" people appears to be huffing solder fumes without a fume extractor. Doesn't seem that brilliant to me.

Wait till you try to find out the price!

I recently installed a full-house solar and backup power solution at home. It cost a lot of money but the peace of mind I have now is priceless. My country's electrical grid is falling apart, on some days we have up to 10 hours of no electricity, and this year alone we've had at least a 2 hour power outage every day.

Bottom line, it's quite expensive, and surprisingly complex to plan and spec out. It's nearly impossible to advise on the questions you asked without more information.

My suggestion is find a local installer and work with them. This is not something you DIY and the experts know what's available and what works best in your location.

Bottom line: - Powerwall is quite overpriced for what you actually get I believe. - This lunar product is most definitely going to be overpriced for what you are going to get. - Don't waste your money on any lead-acid based battery systems. Lithium tech has become cheap enough that even in my shitty 3rd world African country nobody is selling anything but Lithium any more. Longevity is so much better than lead-acid that it can't even be compared.

I'm not sure where exactly in Europe you are but have a look at Sunsynk's line of products. They manufacture and sell inverters and batteries and are Chinese/UK based. Their CEO/Figurehead is UK, so I would imagine they have reasonably good penetration in Europe by now.

By the limited information provided in their engineering video yes, it's basically a battery + BMS in the really big box and a charge controller, inverter and service disconnect in the other box. The batteries seem to be liquid cooled though.

Correction: it's a complete solar system (sans panels) packaged as an all in one system. Looks like they're trying to applelify solar
