Firming up the quotes on my daughter's installation I wanted an external installation on the wall that the consumer unit is mounted on internally. The installer thinks this is unusual but I am concerned about access in the event of a fire of the pylontech battery with a loft mounting.

I think dropping external SWA cables on the external wall from the two strings to a hybrid inverter and battery should make for an easier install but your thoughts would be appreciated.

Also recommendation for a weather proof external cabinet would be helpful, if we do go my route. It will have to accommodate the inverter and 3 pylon 3.5 battery packs.

£10k worth of stuff... I would think it needs to be weatherproof and secure!
A friend suggested to me that extenal wires were the norm. I hade been fretting about runing a new channel down the wall of a bedroom which didn't otherwise need to be disturbed into the porch underneath: he said "Straight down the outside wall!"

I went down the Fire risk / not wanting batteries in the house.
First option was a Metal ? Shed. ( Do not buy one. Complete Usless Design ???? )
Rain / water came in various places.
Windy day. It bent / smashed to bits.




Got two plastic ones. Well impressed. No leaks / No problems.

Reminds me of watching someone livestreaming the slow destruction of an outhouse in a hurricane about 10 years back.

ALAN/ALAN D, just noticed, you seem to have some wind and PV, why not join the Camelot Members Annual Green Electric Generation, we are at over 1/3 of a GWh with 57 members. Just let us know your average annual generation from PV and wind. PM me if you like.

I installed the battery inverter and rack of batteries in a timber shed that was made locally and intended to be a log store. The company (Dorset Log Stores) modified it for me by adding doors on the front and it's just about ideal, as it had to fit into a narrow space alongside a path, so the ~2ft 6in depth both fitted the space and has enough room for the rack of batteries and the inverter.

Only thing I had to modify was to add some ventilation to keep the inverter temperature down. It used to get up to around 65°C when charging flat out but with the ventilation it rarely gets to 50°C. I have noticed that the inverter gets a lot warmer when charging than when discharging for some reason, perhaps it's not as efficient in charging mode.
