Shed Power

This DJI unit gives 2 kWh of storage (expandable in 2 kWh chunks) outputs up to 3 kW (as you wouldn't be using it in grid-tied mode) their own solar panels are a bit weak (coming in multiples of 200W intended for portability) so add your own?

There are bunch of power supply in a box type of solutions that can also be charged while in use from solar panels...

Google Jackery, Bluetti and other similar product. However the price is probably more than doing a properly installed submain feed to the shed.

The yellow extension cord is not UV resistant. Maybe at twice the price, their is a "weird-jacketed one" for UV.

I have the same arrangement - an unpowered shed 40m from the mains.

As someone pointed out it isn't beyond the reach of an extension cord, but it would be more fun to make it self contained. It remains unpowered but this was my thought:

Minimal permanent installation might be wise - less work and future-proof. So maybe some LED 12v lights, but otherwise a portable battery with various outlets and jacks like this:

Obv if your usage amounts to more you might need to up the battery capacity and the solar/wind output to match as well, but just to meet your needs, no point over-doing it.

If you are going to have to carry that too & from the shed, why not just get an old car battery (maybe stick it on a sack truck for transport?) and run everything from that? Those Jackery power stations aren't cheap. Pretty much all the power tools I use in or around the shed are 18v battery, so lack of a 240v option isn't a problem for me at least.

You must remember the B&Q 'joke' wind-turbines?

I don't. Was it a good one? Do tell.

TW

There were sold as generating up to 1kW, turned out they could consume more power than they generated ...

I must have been busy with my life in 2006. What a nonsense!

Couldn't anyone with a couple of O Levels have seen that there wasn't a KW of energy needed to turn the turbine, so there was no way a KW was going to come out of the wires?

Small wind turbines will never replace power stations but they have been used for years on yachts and boats, not to power instruments or lights but to trickle charge batteries when the boat is unattended - which is all week for a lot of boats - and might be the same sort of usage as Rob's shed. Or maybe supplement a solar panel in the Winter, IDK. Even on boats they are falling out of favour now solar panels have become so cheap.

The problem with the Windsave turbines was that unlike marine ones charging batteries, they were connected to a grid-tied inverter to produce AC power and the inverter would draw mains power 24/7, irrespective of wind.

I have a mental image of one of those little windmill things we used to stick in the top of our sandcastles on the beach.

The outcome of this comparison should not be a surprise: $100 Solar Panel vs $100 Wind Turbine in a Normal Backyard "

Plus you can get a 4x more powerful solar panel for your $100

As an alternative, 20w LED rechargeable worklight with USB from ALDI. A selectable mix warm/cool white, so might manage 2 hours on low light.

Thanks - like the look of that Jackery battery, and as you say, plenty of options for charging.

Yes, quite right, I'll get a quote. I can do the trench so that should bring down the cost a bit.

I still like the idea of 'off grid', though - even if it won't work as well as a mains supply.

There's also Anker. I have one of theirs.
