For example, I have a single, old Loran in the orange airplane. In an email recently, I mentioned offhand that the orange airplane was apart again. I'm thinking of leaving the airplane in Santa Monica for a few weeks, what is electric cable to let Bill Heard make a bunch of more substantial modifications to the cowl. Helps me get my thinking straight. What we really need in these aircraft is enough equipment to get where we're going without worry. When discussing specific defenses there is a tendency to get lost in absurd what-ifs - things that would require levels of ability and determination out of all proportion when considered coldly in the context of your situation. There are many newer designs available (with features, that e.g. allow the protection of the load, higher efficiency and smaller components) to the professional market. Not fully on topic for what you describe in this very good how-to-guide, but anyways: for everyone that may have concerns about electromagnetic fields (EMF) as raised by Wim’s earlier comment, I can recommend the website of the German federal office for radiation protection (BfS) as a halfway neutral resource. Indeed I have read that DC is a much better option regarding EMF.

We often don't need two NAVs, much less five (two VORs, DME, ADF, and Loran or GPS is not at all unusual even in aircraft which are not maintained well otherwise). There is no instance yet of a well-manufactured heavy cable breaking or giving out in deep water after it has been carefully laid free from defects; but there may be much due to the external covering keeping it quiet; there has assuredly been a great deal due to the external covering in the successful submerging, and there is no experience whatever to justify the assumption that an unprotected core would last, even if laid. With all that computing power and expense, why not create a device that monitors the engine intelligently and raise alerts when necessary, instead of giving the pilot lots of diagnostic information when he should be flying the plane? For now, I don’t have rooftop solar panels as it is a rather large expense, but I hope to have them installed over the next 2-3 years. Given that I will be installing rooftop solar in the next 2-3 years, I don’t want to buy a big, expensive battery for this (relatively temporary system).

2) Bad choice of relays - according to the datasheet, the relays used in this project are for EV chargers and can handle 250V 40A. EV cars soft start/stop their charging so the relays don’t have to connect/interrupt under load unless due to a fault condition. For these reasons a final judgment on the figures given must not be reached; yet the facts presented are indicative of what may be expected. Hence, a fuse with higher breaking capacity must be selected to guarantee (!) the disconnection of the energy source. UL type definition : Fuse can carry only 75% of the rated value without tripping. The most common type of electric power cable is that which is suspended overhead between poles or steel towers. Glass type fuses may just have some 30A breaking capacity. Perhaps an army of a/v tech, rock climber, sailor and a topologist would have helped as suggested by this xkcd comic. George Cove, a forgotten solar power pioneer, may have built a highly efficient photovoltaic panel 40 years before Bell Labs engineers invented silicon cells.

The current of the first panel could then "bypass" the shaded second panel without high losses or the risk of damaging the solar cells. I want to further point out that some of the cheapest offers come with the risk of counterfeit components with greatly increased failures rates. Also temperature and history of the fuse (inrush currents, very brief short circuits, age, etc) can change the tripping point of the individual fuse (hence manufacturers give a a range chart for the tripping current and time. A premium Waiheke accommodation for groups of up to 9, it’s both luxuriously appointed and lushly landscaped, so you’ll love your time inside and out. Every time a load (especially inductive loads as a fan) are switched (off), the arc formed in the switch wears out the contacts a bit (but also "cleans" it from oxides formed by humidity, etc). Stress cones are also a useful addition to any medium-to-high voltage wiring where the shield cabling is being terminated. However, the magnetic coils and higher intermediate conversion frequencies in DC-DC converters and charge controllers (especially if these are less reputable "I-just-found-this-on-the-internet" products) may be tricky, so also keep these away from your head.
