Insulating Timber Garage

[Joeboy]

Picked up guttering etc but too rainy to do anything

Fixing for rails turned up too

Good to see you didn't do a bounce test.

[AGT]

Plenty time for that, with 6 rails to fit, up and down off the roof, fitting dwangs for each bolt!



Currently lining the wall for inverters, DB, isolators and a workbench area!

[AGT]

Just playing with layout, now that wall has been built to take electrics and my workbench underneath.

Good progress, nearly finished AC side

Made off the DC cables at the inverter end with MC4, didn’t realise it’s a different connector.

Another delay.
Picked up T25 driver bits to put the screwed rod into the timber, 10mx 4x2 to put dwangs in to give extra pull out resistance to the bracket system.

Another delay.

SMA inverters use their own proprietary connectors which look similar to MC4 but aren’t. I quite like them as you don’t need any tools and they can be re-used. The pins on them are more robust too.

Yes found that document when I was searching for them Sunclick or Phoenix contacts.
£15 for 2 was the cheapest, so ended up buying MC4 panel mount terminals for £4 instead as I have MC4 connectors in the spares bin.

AC Complete, Labelled etc etc
DC connectors sorted and DC checked from new inverter connections back to ‘combiner box’

5v desk top fan pointed at heat sink too, as garage gets a bit hot in the summer and don’t want any premature electronic failures!!

Garage DB isn’t connected to this PV system, it’s 2 different SWA cabling back to house, 1 for DB, 1 for PV
Found remaining RCBO’s MCB, fitted them all so they don’t get lost, a few dedicated socket circuits to run for workshop use

Looking good, shouldn't be too long before solar power is flowing.

[AGT]

Soon hopefully,
Got to make rails up, get onto roof, drill 24 holes for fixings, fit 24 dwangs on the underside of the roof to beef roof up, install fixings, add extra waterproofing to fixings and then rails.
It’s the up and down that’s the time consumer, worth it in the end though!
