The skil brand belongs to Chervon. They are indeed quite decent. I've seen their Devon brand in asia and it's one of the best brands outside of the big names we all know. https://global.chervongroup.com/en/what-we-do/our-brands Just a little caution over their cordless. There have been issues...

Meters do have an official life. They must be guaranteed accurate within a standard tolerance, for a period of 10 years or whatever. Past that date, then you as user have a sort of automatic right to question the readings, so the meter companies should track their dates and replace them when...

This is typical enough of a day in the life of our system throughout the better 6 months. As you see we don't work the battery hard at all because we have plenty of PV, and the battery does spend a lot of time up in the 90%'s. It may make little difference, but it only takes a couple of minutes...

That makes good sense. I've been refererencing info like this found through https://secondlifestorage.com/index.php 20% to 95% SOC keeps you very well away from the bends at each end of the batteries charachteristic curve, but the real distinct bends in the curve are above 99 and below 15%

One saving grace of cheap supermarket powertools like LIDL Parkside is that they often come with a 3 year warranty. The tools are cheap. Full stop. Their designers aren't aiming for lifespans of 8ours a day, 250 days a year, 3 years life. They are aiming for 10 or 20 hours total runtime to total...

This is part of the argument in favour of hybrid inverters. Staying DC between the inverter and battery saves a percent or two. It's not really enought to worry about but technically there is a benefit.

DC-DC buck and boost converters are pretty cheap and efficient. Laptop and many electronic power supplies have a wide input voltage range. They have a bridge rectifier on the input but would still work if fed from DC in their band. A DC supply at 48, even 60 to 70 volts for example might be...

Question for @johnb80 as your researches into DIY storage may have given you better info than mine. Having gambled more money on a commercial battery that probably has lower performance cells in it than yours, I'm keen to maximise the life of what I bought. 16.6kWh battery is currently set to...

In a domestic setting you can do what you want but The colour will be wrong, so potentially confusing to anyone else. Compressed air needs a hose safe to maybe 15 bar / 160 psi plus safety margin. Fuel gas hoses are rarely used anywhere near that pressure. You have a regulator at the cylinder...

A very relevant comment. The starter box is full of wood dust in the photos. It absolutely should not be. Cables in and out of the box should be made with cable glands for dust proof seals and any holes left open after wiring changes should be blocked off with rubber blanking plugs sold at an...

And to give you some encouragement: As long as you have 2.5mm2 conductors minimum, we're not worried about the current capacity of the cable. It will be ample. What we're interested in is the voltage dropped or lost across the length of the live and neutral wires over a 35metre out and 35m back...

Not done but I've wondered about this job. My two thoughts would be hot melt glue as a bodge job, or much the best would be hot weld. Think car bumper repair where they use a hot air gun with a narrow nozzle and feed stick of plastic (not glue) in at the nozzle to melt and bond with the...

Photos here, Doug's too .... https://www.ukworkshop.co.uk/threads/table-and-mitre-saw-blade-quality.138352/

People talk about "drinking the green koolaid" to criticise the premium prices of Festool kit with their distinctive green brand. Freud are worse with their trademark red blades. Put a Freud blade alongside a real trade or industrial sawblade and you'll realise they are a very inferior product...

My big maxeon solar panels make over 70V apiece and in strings of 8 they actually exceeded the real input voltage limit of my GEN24 inverter (supposedly 600V), so we had to reconfigure some of the strings. The old tech 3kW inverter however is quite happy with 600V. I know it's not the same as...

Yes. It was a commercial supply and fit so I've never been inside the battery boxes, but they are indeed 16 cells per module, 6 modules wired in series so a 300V DC input into the hybrid inverter. The 16.6kWh stack can degrade to 80% capacity and still deliver 6.5kW at 0.5C. One of my...

Measure it for us when you get back Jacob, that'll be easiest. Cheers

What impresses me from this is the improvement in LFP cells. Prompted by this thread I've been looking at the prismatic cells that @johnb80 has used and comparing to the commercial battery pack that I bought only a couple of years ago which uses the same chemistry. My battery is assembled from...

I think the idea is to hold the sleeve so that it's around the head of the nail, have some sort of bit inside the tube to transfer the force and then just take a deep breath and belt the end of the hex shank with a hammer (Estwing :) ) Pretty much a guided pin punch.

Can you see printed on the cable sheath or anywhere alse, what is the size of the cable ? 1.5mm2 or 2.5mm2 conductors. We need to know that to do some math and work out how much the voltage will drop over a 35m round trip. Ignore the breaker, what matters is the detail of the Steel Wire Armored...
