@Phimx. To prevent us going round in circles, let's say given what we have been told it's completely possible that the charger is able to produce 6.4kWe off 20kW in, whilst simultaneously producing 12kWt at a system efficiency of 92%. Happy? :-)
Now let me explain why that is a monumental achievement if so.
First some background. Elon Musk in his infinite wisdom (all praise the Musk), had a vision of an electric vehicle world. In order to make it affordable for the masses he produced a master plan (worth a read, if you haven't seen it!). The plan was: Create a low volume car, which would necessarily be expensive. Use that money to develop a medium volume car at a lower price. Use that money to create an affordable, high volume car.
So? What's this got to do with Inspirit Energy? Well... Just because an initial version of a product isn't necessarily suitable or affordable for all markets, doesn't mean it can't be profitable for certain markets in certain sectors. Later versions can be developed which target other sectors. e.g. wall mounted; more thermal; heating elements for peak supply (!?); smaller; lighter; cheaper. You get the gist. The way I see it we are at a stage now where the BoD have determined exactly who the customers for the 3.1 version are, and are set on making this a reality.
IMHO, they need to get a product to market, any product will do! ASAP! ;-)
So why is 6.4kWe + 12kWt better than say 6.4kWe + 18kWt or 6.4kWe + 24kWt, all at 92% efficiency, when the Inspirit Charger acts as a lead in a boiler environment?
I'll let you think about it for a moment. Got it? ;-)
OK - let's consider the 6.4kWe + 12kWt vs the 6.4kWt + 24kWt (the same logic applies to the middle one)
The first scenario benefits premises which have a fairly constant thermal load of greater that 12kW. The second benefits when premises have a fairly constant thermal load of greater than 24kW. By DEFINITION there are more properties which match the former scenario than the second. Additionally, properties matching the second scenario which have the space will benefit greater by buying 2 (or more) Inspirit Chargers to potentially double the savings per year.
We haven't really got to the economics from the point of view of a customer (CapEx, IRR, OpEx, NPV etc), but I'm sure you can see without really going into the details how attractive it will be at a saving of something like 60p an hour for 24 hours a day, for 350 days a year = £5k. Even if the early units cost £10k - a payback of 2 years, and then continue to save £5k a year for a further 8 is outstanding! Ultimately that £10k will reduce to ~£3-4k for this model (maybe even less!) - so for customers where the £5k saving is more like £1-2k a year it becomes very attractive to them! If you have the space and can use the electricity, store it, or feed it back to the grid you'd want 2, 3, 4 even! :-)
