Advice on location of inverter for Solar Panels

Conorkcp

Hello

I'm getting solar panels installed at the end of January (Enniskillen crew). I'm interested in adding a DIY battery at some point in the future, and so I'm thinking about putting the inverter in my shed, which is about 12 metres away from the house. This would allow me to put the batteries in the shed down the line. There are ducts connecting the shed to the house already.

Is this a good idea/make sense? Any advice on the best location for the inverter with a view to adding DIY batteries in the future would be much appreciated.

In my opinion:

1. The shed will get cold in the winter and you will end up using energy to keep them warm
2. the inverter generates heat and putting the inverter in the shed will waste that heat

I have everything in the utility

The shed will be very useful for a DIY battery,

A) space

B) out of sight.

A insulation box for the batteries, you'll have no issue with the cold.

Thanks, I think this makes sense and can insulate the batteries as you suggest.

Do you know how many / what size cables the electricians will need to bring from the house/panels to the shed? There is a power cable in place already bringing power from the house to a fuse box in the shed, and an empty 25mm duct. Will that be enough or will I need another duct?

There's a 4mm2 running to my dad's 6kw solis. What's running to the shed currently?

Will also need a way of bringing the ct data out. There is wireless options too. Wired is usually best though.

Also.. 25mm conduit. Don't envy anyone trying to pull a cable in that. (For anyone else reading, put as big a pipe in as possible)

wouldnt dc power loss start to be an issue over that distance.?

It's not an issue mines 50-60m away from my inverter, although I have mine on 6mm2 for a majority of the run.

But for most places even 4mm2 is plenty.

This is exactly what I want to do. Put the Deye 10kw or 12kw inverter into the shed and get rid of the inverter in the attic.

How do I go about doing this? Can anyone recommend a REC that I could use? Consumer unit to back of shed run would be about 20-25m. Would likely need 16mm2 AC and also need to run the DC cables for the solar. Not a deal breaker but I'd also like to use the EPS feature on the Deye too. Please someone point me in the right direction

what kind of form would an insulation box take? Is it something fire resistant that would be suitable for an attic (assuming fire resistance less of an issue for a shed in the case of the OP).

Dunno what I was thinking 2 years ago!

But if building a battery now, just put of ease of build, and neatness I'd use one of the steel boxes and the prismatic cells.

Can get ones with heaters now.

As for insulation, possibly some sort of fire resistant board to surround it?

Rigid floor insulation (with foil removed on battery side) is what I intend on using
