Re: Dealing with excess solar:

I have this problem with my extra Hoymiles PV - where the voltage goes above 253 during exporting and it trips out. ... It still tripped out most days over the past couple of weeks - but in most cases not for too long. It's frustrating I too am quite close to the limit. Fortunately I reused an old ...

Re: 102.5% US Tarriffs on BEV's

Very much related I'd say. I read yesterday that Ford is making an average loss of $100,000 per EV it makes which if true is insane. I know their sales of the F150 Lighting aren't exactly setting the world on fire, but are they really that far off making them at least break even? No wonder they kee...

Re: Dealing with excess solar:

Also, for a DC side battery, especially with the massive Wp overcapacity that Solaredge inverters can handle (up to 200% of rating), then it may be wise to prevent the battery filling before peak generation, so that the inverter output + battery diversion, doesn't fall short of generation. PS - My ...

Re: 102.5% US Tarriffs on BEV's

Lucid? Well they're now basically owned by the Saudi Government, and they have signed a deal to supply 100,000 cars to the Saudi Government, which included opening a final assembly plant in Saud, and the Saudis basically have unlimited money (until the oil runs out!), so I think Lucid is safe for t...

Re: 102.5% US Tarriffs on BEV's

Lucid have improved and gotten their per vehicle loss under $400k now. Is that the correct figure Mart??? Scary isn't it? As Dan says, some estimates are lower, but it's typically based on the cost of production in a quarter, divided by sales. Lucid is now producing less than they sell (I think) du...

Re: Cam Pets, or Petcam?

At the lake a pair of silly Coots decided to build a nest in the open, next to a walkway, on some weeds. Then as it rained and the water level rose, or the wind caused rivulets, they worked tirelessly to repair the nest as fast as it was falling apart. Well, their hard work (and stupidity) has been ...

Re: Cam Pets, or Petcam?

Will he make it to his (and our?) 10th anniversary on the 6th May ....... I've no idea, but he's still happy, eating and purring, but ever more wobbly. Hope nobody minds this trip down memory lane. My how time flies. Yes, of course he will :xx: You called it, he was still with us this morning. And ...

Re: Finnish project to store 90GWh for district heating

Mind blowing, to store a years worth of heating energy for the town is one hell of an investment. I'm not sure how much total storage the UK will need for a 100% RE/low carbon grid, but perhaps 2 weeks worth(?) So whilst seasonal storage probably isn't needed, if PV panel costs keep falling, then be...
