	RE: Recommended home battery inverters + regulatory matters - help requested By JamesPa, 4 hours ago Forum Energy Storage
	Thanks for all the help/comments. I completely agree with the above, I just want to be sure that there isn't an 'artificial' blockage at the end requiring someone who 'plays awkward' and for which t...

	yes, the circuit needs the usual protection, mcb and maybe rcd. then you also need a lockable isolator.. I am 99.99% sure the Solis will do this as required (just best to have the Solis distri...

	@jamespa re when to switch back, you would have to switch back on if the battery was flat! A look out of the window would tell us whether there was any mains to switch to, or it was torch time. ...

	RE: ASHP Energy Consumption: Aira 12kW heat pump By JamesPa, 9 hours ago Forum Air Source Heat Pumps (ASHPs)
	I doubt that matters, ToU tariffs are for the benefit of the grid and electricity suppliers not to aid the transition to EVs. They have been around for decades as a means of load shifting (and thus b...

	RE: ASHP Energy Consumption: Aira 12kW heat pump By ChandyKris, 10 hours ago Forum Air Source Heat Pumps (ASHPs)
	Batteries have been a great investment for us. They definitely help us keep the costs under control in the winter. Who knows how long the EV tariffs would last, but with a big push towards EVs it woul...
