Seems like amazon might work out cheaper, especially if you buy it along with other things: https://www.amazon.com/Genuine-Replacement-Cushions-SENNHEISER-Headphones/dp/B002B4OKYU/ And also remember to replace the headband foam, if the earpads need replacing, the headband will probably also...

Depending on your system, if DSD actually makes it to the DAC, it usually gets handled specially, most notably the filter is different. That means that comparing it to PCM is impossible. From a theoretical standpoint, it uses more bits for storage/transmission without adding more information...

Yes, from the element to the water is the most efficient path. Otherwise an external part of the geyser will get very hot (or the element will just keep on increasing in temperature until it fails). There is no other place for the energy to go...

This is not a valid test unless you can prove that the temperature in the geyser is homogeneous (which it should not be under normal conditions).

This is correct. I can't believe people are even arguing about this.

Pretty much all repair shops (even in EU) use leaded solder, because it is easier to work with, and lower temperatures means lower chances of damaging boards or components...

Why would you need to use lead free for repairs/hobby use? Locally it's really hard to beat techmet on either price or performance (at least in my experience). I have not tried their lead-free offerings. https://mantech.co.za/ProductInfo.aspx?Item=340M0098...

You cannot use panelflex, you will not meet code. (IIRC, it needs to be SANS1507 certified). Some panelflex is CCA...

Those claim they can do it continuously, and the BMS will allow it, but I would not do it if you want them to last. The internal resistance is too high and causes too much self-heating for longevity. I would not recommend going over 0.5C on any of these rack mount batteries. (well if Pylontech's...

Be careful - most of these batteries are not rated for UPS duty. They need to be able to supply enough current for the UPS, which very few batteries can do. A UPS rated AGM battery usually weighs about double what these "alarm" batteries weigh. The LiFePO4 replacements don't come close to the...

I would definitely rent first when moving to a new country in order to familiarize yourself with the area/customs/unknowns. It seems your situation is a bit unique in the sense that you can afford more than you think is sensible, thus your question here. That makes it much more of a personal...

Start off by shopping on emotion, and then tame that back to what is affordable, with a safety factor built in.

Well, you won't get away from import duties, but shipping might be cheaper. You could always check the costs on digikey with shipping (but excluding duties + vat) and also ask for a quote from NuVision?

No, they don't have local stock. If you order from them directly it will come in from abroad and you pay shipping, duties + vat. If you order through their local representative (nuvision), they pool your order with others and add their markup. So the saving is shipping cost by pooling. If your...

The earth is to give a lightning strike or discharge a better path to follow, otherwise it will follow the path through your inverter.
