	RE: Free Ecoheat Heat Pump Install By Deltona, 19 hours ago Forum Air Source Heat Pumps (ASHPs)
	Thanks for the tip, I watched his two house installs over Christmas, but not the inlaws one yet. He's certainly a smart guy. As previously mentioned you need the practical experience to go wit...
	RE: Recommended home battery inverters + regulatory matters - help requested By JamesPa, 19 hours ago Forum Energy Storage
	Thanks Ah, so that places the 'off grid' port of the inverter between grid and load so protecting the grid. However it does introduce another complexity: either the inverter must be capable of supp...
	RE: Recommended home battery inverters + regulatory matters - help requested By Transparent, 20 hours ago Forum Energy Storage
	No. The Solis and Sunsynk inverters which we're discussing have two separate ports, both of which can supply household loads from your incoming solar. One port connects to the grid, and will cease to ...
	RE: Radiator sizing sanity check By JamesPa, 21 hours ago Forum Thermostats, Volumisers, Buffer Tanks, TRVs, Pumps, Piping, Valves, Radiators & Controls
	As I mentioned early on the cost of supplying and fitting a few rads is negligible. It certainly shouldn't come to legal proceedings if this is the bulk of whats needed!
	RE: Radiator sizing sanity check By Papahuhu, 21 hours ago Forum Thermostats, Volumisers, Buffer Tanks, TRVs, Pumps, Piping, Valves, Radiators & Controls
	@jamespa Luckily I have the whole process documented as I could see it had become a comedy of errors. The insulation measures were installed by a sub contractor to the sub contractor, neither of whic...
	RE: Radiator sizing sanity check By JamesPa, 21 hours ago Forum Thermostats, Volumisers, Buffer Tanks, TRVs, Pumps, Piping, Valves, Radiators & Controls
	Thanks for the update. As you say you are now piggy in the middle. Its sometimes said that legal cases are won by those with the best filing system. Your main contractor will presumably say that he...
	RE: Recommended home battery inverters + regulatory matters - help requested By JamesPa, 22 hours ago Forum Energy Storage
	@batpred, @transparent thanks Since the inverter isn't between the mains and the CU, does this need an (automatic?) cut out device that is between CU and incoming feed. Surely it does? Apar...
	RE: Radiator sizing sanity check By Papahuhu, 22 hours ago Forum Thermostats, Volumisers, Buffer Tanks, TRVs, Pumps, Piping, Valves, Radiators & Controls
	@jamespa A minor update. The heat survey was repeated yesterday and turned out the heat loss in bedrooms was wildly inaccurate. The original survey was done on the basis of information provided by th...
	RE: Recommended home battery inverters + regulatory matters - help requested By Transparent, 22 hours ago Forum Energy Storage
	The configuration you will implement depends on what your DNO's Network Planner will approve. Whilst both approaches you've described would appear to be technically achievable, it's the Regulations wh...
	RE: Recommended home battery inverters + regulatory matters - help requested By Batpred, 22 hours ago Forum Energy Storage
	It can be made to look as complex as we want! I believe the safest from a reg pov is to use scenario 2. Since your sunnyboy does not have a CT clamp and the G99 scheme expects one. 2) conne...
	RE: Recommended home battery inverters + regulatory matters - help requested By Batpred, 22 hours ago Forum Energy Storage
	I currently have this setup with the CT clamp/coil being connected "via" their (optional) meter to the inverter. It works without any dependency on the cloud. All access to the internet is via an opti...
	RE: Recommended home battery inverters + regulatory matters - help requested By JamesPa, 23 hours ago Forum Energy Storage
	Thanks all for the help, this seems to be nearly as complex as heating! My current thought process, and the remaining questions, are this: New battery inverter with perhaps a 5kW max out...
