If you do suspect you are the victim of a "reaction-troll" you can still report such posts, remember the all-seeing oracle knows who reacted what ????

Sorry, it was me, I couldn't resist. But yes, it was, along with ha-ha. We shall see how it works out.

Argh!! But not seen since 2015

I must make sure that "Somebody" isn't an allowable username ????

This post was Ha-Ha'd by me, roo860 and MJCM (just to prove we're not bluffing) ????

Note for above post - HaHa reaction placed just because I can!!!!

It certainly looks like a decent install, shame they lost the earth braid for the door of the ATS cabinet** ** Sorry, it's part of my job to notice things like this, with public-facing systems everything has to be 120% (yes, even here).

Not sure if this is the same video.

We are talking battery packs here!

I imagine it's along the lines of the EV pack warranties, 90% (or whatever) capacity after 10 years.

Your arc welder works at 50-60V and 100A or so. It's pretty bright and hot. It's also current limited and easy to disconnect. Imagine an arc capable of a few kA at 400V with no current limit and no means of disconnection! That will blind, cause severe burns and even kill unless the correct PPE is in use.

Using a HV pack reduces the load / charge currents. 10kW @ 50V (48V pack) is 200A = pretty fat wires. 10kW @ 300V (288V pack) is 33A = much more manageable cable sizes. Also, you can use smaller individual cells, cheaper to manufacture, more mature production process. 10kWh @ 50V = 200Ah so 16 x 200Ah cells. 10kWh @ 300V = 33Ah so 96 x 33Ah cells. Of course, this comes with a more complex BMS, but electronics is cheap and reliable these days. The dangers associated with HV DC supplies really preclude DIYing, the risk of shock and arc-flash is just too great. Stick to 48V in the DIY world although even 48V can get pretty "exciting" if poorly implemented.

I don't think it's a million miles from what I'd expect for a premium, contractor installed system here in Thailand. The Alpha kit is certainly not "budget", it's also not DIYable (HV batteries etc.). https://www.kitjarak.com/product/107/Alpha-ESS-SMILE-T10-10KVA-with-Battery-11.6-KWh The equivalent Sofar (premium DIY) 10kW 3-phase on-grid hybrid inverter is about 65kBaht. Panels, say 5,400 Baht for 450W mono x 25 = 135kBaht Packs, Seplos 10kWh are 2,600USD ex-China so say 6k US for two by the time you've paid shipping etc. - 200kBaht So big ticket items 400k Baht, I'd be expecting to pay materials x 1.5-2 when installed so 600k - 800k ish. @gamb00ler are you set up to export excess to the grid or are you purely grid-assisted like @Bandersnatch? I would agree with @BritManToo on the roof installation, if, that is, you had space for a suitably aligned car-port. Easier maintenance and rather less visible. Let's hope the installation crew live up to the price.

Panels on their mounts would be nice ???? A system diagram maybe (they did give you one didn't they?). If it looks good and pro your installer could get work out of it too ????

Sooooo, you know the first question everyone is going to ask.... Owmuchizzit?? Can we have Some piccies of the panel setup please?

Dunno about True, but with AiS your TV subscription comes via their PlayBox which connects via LAN or WiFi. EDIT It looks like True do the same type of thing https://trueidtv.trueid.net/en If doing a new build, I'd run "data" conduits to wherever you think you will need wired data. You can decide what you put in them later.

Yeah, like those satellite dishes printed to look like brickwork or siding, seemed like a good idea at the time. I've not seen one for years. They must be really good now

As always, there is a solution. https://www.novuslight.com/camouflage-for-solar-panels_N10722.html

@Digitalbanana which country were you trying to connect from?

They call it rubber splicing tape just to confuse, search for "Scotch #23" Also, at any good electrical specialist outlet.

And don't call me Shirley! 43 years ago for flips sake!!

The hinge mechanisms will be happy with a good squirt of an aerosol grease (not WD-40) unless they are actually busted. For the locks, pop one off and start visiting hardware stores, many will know where to go if they don't actually have them. The old girl in our "Magic Shop" knows everyone. Turn up with a thingy-doowaddle and if she hasn't got one hiding out back, a man will arrive shortly on a motorcycle with the relevant article.
