will the microinverters play nice with the gennie or will their smoke leak out?

Passive House, storms and power cuts
dpmiller replied to Russdl's topic in Energy Efficient & Sustainable Design Concepts
ours has been off for a number of hours (3-12) three times since we got the mains connected. -
Surely the boiler stat has the veto here?

Passive House, storms and power cuts
dpmiller replied to Russdl's topic in Energy Efficient & Sustainable Design Concepts
I note that the comments negating the likelihood of outages *aren't* coming from folk that live out in the sticks where power is HV *and* LV overhead... -
why is the RHI so important?

Something must've changed over the years- 3-bar electric fires and various other 3kW heaters also used to work off a plug just fine back in the day, but nowadays a 2.5kW tumbledryer overheat a plug. And don't start me on 3kW elements in Water stills that run all day long, on a 13A plug...

@Nickfromwales why would it be Solaredge if he's got Tigo smart panels?

I'm intrigued by the other unnecessary gizmo in the loft- was it a WIFI bridge for monitoring? With some systems it's a mandatory requirement for G9x compliance... You still haven't told us what inverter you have.

continuously lit or PIR? There are chinesium solar floods that can be wall or pole mounted, I've one of these on the corner of the house and it's very impressive https://www.ebay.co.uk/itm/233670054949

It definitely has a moving part, and... how can the COP be greater than 1?
-
can someone educate me what "this kind of interior" is please?
-
@vala you might try doing both tbh.
-
so they should be cheaper as their own brand then
-
never heard of them.

it's more a groundworker thing than a plumber thing, if you ask me -
QS/project manager for timber frame house in SE London
dpmiller replied to cc247's topic in Surveyors & Architects
That reads very expensive... -
@vala yes. But what is the pump set to/ can you turn it down a speed?
-
PRV will control dynamic pressure at it's point of fitment. The softener's restriction is dynamic, not static. So static pressure will be the same for all past the PRV yes, but once there is flow then you'll lose some part of that 0.5 bar everywhere after the softener
-
as wonderful as the Salus jobbies are, perhaps they struggle at the small openings required if there are no other flow restrictions, the stepper will only have a certain resolution. Doing a "rough" balance with the flow meters (and maybe turning the pump down a bit?) should let the actuator work over more of it's span.

"6 mins each" No, it doesn't work like that... -
Is the aquapanel actually needed in this situation?

What's the issue? Help Please ?
dpmiller replied to canalsiderenovation's topic in Air Source Heat Pumps (ASHP)
even with an inverter, there is a minimum current needed for the ASHP to run reliably, plus it takes time to start the unit up and begin producing hot water. You'll miss short breaks in the cloud at times and pay for the balance of the power requirement at others. A diverter can instantaneously respond and change the amount of juice going to the immersion.
