Kia eNiro. Nice car, I got one as well. I don’t think there was an audible gasp in the audience, but the room certainly got a bit tense, and one of the speakers asked us if we were happy with that, expecting a ’no’. I was hoping to avoid buying one for my usage. I think one of the simplest and most straightforward ways to do threat modelling is by user persona, whereby you consider each kind of attacker in turn, making some reasonable assumptions about their level of motivation and methods. What do people think of the EVSE RCD? People often ask which solar panels to buy, but there is little advice to give. While some may think that generally there is no trusting a state-run organization, I do not see what interest they would have to tell you lies. I can see how hardware implemented cut-outs are more robust and safe. Such “direct” or “direct-drive” solar systems are cheaper, quicker, and easier to make. More expensive solar charge controllers (like MPPT) are not worth it for small-scale systems. Regular bits are independent, but the status of one qubit can influence another qubit.
Using several smaller panels rather than one large panel is not the cheapest option because smaller solar panels cost more per watt of peak power. If you need (for example) 50W of 12V solar power, you can buy one 50W solar panel or several smaller panels (2x25W or 5x10W) and wire them together in parallel. Of course, you may just as well get a 24V solar panel. Wiring solar panels in series allows you to power 24V devices with 12V solar panels. You can only charge these devices during the day. I dread the day my plane needs paint. The biggest drawback of low-voltage power is its relatively high energy loss during transmission, what is electric cable especially for powerful devices. There is often additional energy loss (at least 5-15%) in the conversion from AC to DC power because many modern devices operate internally on low voltage. There is not much to say about the PCB design. That’s four times as much information. This guide brings all the information together: what you need, how to wire everything, what your design choices are, where to put solar panels, how to fix them in place (or not), how to split power and install measuring instruments. Just taking the time to look at some of the content they provide gives a fairly good idea – I find them to be a good source of information.
To come up with better advice requires a threat model, which is a piece of jargon for taking a holistic view of the danger posed by attackers. The system then becomes a battery storage system based on lithium-ion, taking advantage of the power management already available in the power bank. Before you start: do you really need a battery? Both systems also need electric cables, fuses, and connectors. This applies to wires, switches, fuses,… For portable solar systems with batteries, lithium-ion is the most practical option. If you charge portable LED lights with batteries, a solar panel can even keep the lights on at night – a modern approach to the torch. Conventional solar installations for households always use an inverter, which converts the low-voltage DC power from a solar panel into the high-voltage AC power used by main appliances. They convert the low voltage direct current (DC) power produced by solar panels into high voltage alternate (AC) power for use by main appliances and rely on the power grid during the night and in bad weather. Directly coupling a low-voltage DC device to the low-voltage DC power produced by a solar panel avoids these energy losses and results in a more energy-efficient system.
You can put them between the solar panel and the solar charge controller but also between the solar charge controller and the load. You can also wire solar panels in series. It’s best to connect solar panels of the same type, whether you wire them in series or parallel. Practically, you can power the same device with a smaller solar panel. In contrast, a 20 watt solar panel working at half its capacity would need 14,4 hours, which won’t happen. Glass type fuses may just have some 30A breaking capacity. The other components depend on the type of installation you want to build. However, you can often build a photovoltaic solar installation without battery storage. First, it makes solar installation cheaper because inverters are expensive. Examples are power and workshop tools, sound systems, and ventilating fans. These things sound very useful and I know that you have very practical ideas about aircraft electrical needs. But, I agree having a dual gang relay so the L&N are mechanically linked does sound better.
