Tesla Wants to Build a Battery for Your House

So please tell us exactly where to find a Charge Controller and Inverter made to work with a 450 volt battery? Please tell godsend to answer. Inverters can be found, but battery Inverters made in in that voltage range are usually measured in MW, not KW. No such thing as a 450 volt charge controller.
Does anyone have a reference to the 350VDC or 450VDC numbers thrown around in this thread or are these just best guesses?Comment

You see, it's about the warranty. It's alllll about the warranty.
Did anyone (who is open mined) run the numbers for peak shaving based on their electric rates? Maybe assume 2-3kwh used per day over ten years? The system probably breaks even in the $.20 -.30 range. It seems that in some markets the utility could finance the system with a positive cash flow to the owner.Comment

Before the utility does that they would time shift excess baseline power from night periods to meet peak requirements.
Contrary to what some feel, the utility does not exist to give you freebies.[SIGPIC][/SIGPIC]Comment

Solar only potentially amplifies the savings by not selling power back to the utility at a discount and using it in the evening.Comment

Saying something can run circles around something else is nice, but it really doesn't quantify the difference between them. Perhaps you could offer more details/data on the advantages and disadvantages of the Trojan battery *system* you mention? I'm sure you know what they are, but others like myself do not.
I'm slightly suspicious that the Tesla solution might do a few things that the Trojan battery you mention does not.Comment

Powerwall with existing solar
Elon said the system would work 'out of the box' with existing solar setups... As there is no inverter that comes with the battery, is it safe to assume this battery would integrate then into an existing inverter? I'm no electrician and have only just yesterday signed papers for my solar PV system to be installed.. so forgive me if that is an ignorant question... I was just thinking of the Powerwall cost, plus installation, plus inverter.. the installation and inverter would cost almost as much as the battery.. UNLESS it could utilize the existing inverter...
Thanks!Comment

Over the years I've sort of noticed a positive correlation between how early in game someone chooses to buy into a new technology and how much they actually know about that technology - early adoption, less subject knowledge. Same with other things like time shares or solar leases. In general, at least to my view, that is, more subject knowledge, later adoption is also usual and common.Comment

The 10 kwh system will probably frequently need substantial additional expense.Comment
