Battery cable length

[drjim]

So I'm working out where to install my hybrid inverter. Unfortunately there is no ideal place as I no longer have a garage. I can put it on the side wall of the house, and in principle I can stick my pair of US2000C's on the wall next to it, so that works for now. However the path up the side of the house will be narrowed, and 4.8KWH is nowhere near enough battery for my house/dreams! So other than looking at Nowty's US2000 collection I am looking at fogstar seplos kits, which clearly won't go well on an outside wall overhanging the side access to my house.

There is a solution in that the other side of said path (block paved so easily lifted) is a wood store which I could reconfigure into a battery shed.

It would be more straightforward if the inverter was on the house wall, and I just ran the battery cables through a duct under the path to a battery shed. BUt I keep reading that you should keep the cables as short as possible. If the cables are big enough (I like welding cable!) then they could be 4-5M long without any issues, or am I missing something??

I could of course put the inverter in the adapted wood store, but that involves multiple separate ducts for different types of cables, and my electrician would probably want to go for SWA cable, etc etc etc. Not straightforward.

Assuming longer cables would work I'll get it all set up with the pylontechs in a box on the wall for now and then build the battery shed as I acquire more batteries.

I did consider removing the log store and adjusting the path, but that causes issues with redesigning the gate and the bin store the other side of it.

Any thoughts??

Larger diameter cables are indeed possible.
Single insulated
Cables in ducts that can fill with water can be a recipe for disaster.
What about a lean too shed type thing to house everything?

I'd probably use a 110mm pipe - already have some and 90degree bends - run that far enough up to remain dry, then run cables inside smaller pipe/duct for double waterproofing.

I could make a car port/shed type thing but it's the need to run the path through that makes it all tricky.

If I keep the inverter on the wall, there's only the battery cables need to go under the path.

Maybe I'll have a long think about widening/moving the path. There's a really gnarly earth bank full of hedge roots under the woodstore though, which is why I stopped digging last time!

Why dont you put the inverter and batteries in a shed /the shedstore? Then you only need to run an armoured cable under the path for the inverter and can keep the battery leads to a minimum.

You're much better off putting the batteries and the inverter in the wood shed than having batteries in the woodshed and inverter in the house.

I'd need to run the solar feed through a duct as well, but it's looking like the most sensible approach.

And I have got a pile of concrete blocks, plus a pile of facing bricks somewhere. It could be a proper brick house - little pig style!

I wish, i hindsight we had of built a brick/block shed for out set up, rather than the metal shed we went with.
If you can, it will definately be worth it in the long run as wont rot and will be dry.

I do sympathise. We had to trench 10m under slabs this winter in frozen ground to lay conduit for ours, and took the time to tee off whilst we were at it for any planned cable runs to other parts of the house/shed/ garden for solar cables or anything else we may think of.
