Review on BAYM Connector Holder 10X38Mm Waterproof by Eric Garron

Summary: When it comes to photovoltaic systems, from a technical point of view your system is only as efficient as the cheapest bottleneck. When it comes to electrical connections, connectors are the weakest link, so buying a quality offering means investing in the future efficiency of the ENTIRE PV system. This also applies to mains fuses. Remarks: BAYM is not a pure solar company. The first thing that struck me about these built-in fuses compared to some others (listed below) is the color of the o-ring that seals the fuse body section. BAYM o-rings are black, meaning they may or may not be synthetic, while orange o-rings usually indicate synthetic material; However, without a definitive manufacturer's specification of the o-ring material, you're left to guess. As a result, synthetic O-rings last longer over time, which is especially important when you're building a system with a 30-year (or more) lifespan. Another thing to consider when buying fuses is the rate at which they separate. too slow and your system will be damaged. These fuses/holders cost less than $5 each, but good quality 20A 10x38mm solar fuses cost at least the same if not more, so the quality of these fuses is also suspect. Recommendations: 1) The built-in fuse is an additional protection against uncontrolled electrical problems. Circuit breakers offer similar protection, so how do you choose between them? Fuses are usually cheaper but disposable; while breakers can be reset and also used as a temporary shutdown. When it comes to fuses (or breakers), there are many good search options on the internet. Make sure you do your homework (or hire a pro). 2) You can use a digital multimeter (DMM) to check the connections AFTER INSTALLATION. 3) In this respect, the IGREELY metal keys below are much better suited for disassembly. Pros: Good fit and finish, should get the job done in the short term. Cons: Cost ($22 for 5 pairs of 20A, $4.40/set); loose bits of black plastic in two of the five connectors (see picture). Some other BAYM deals: 10 pairs are $42 for 20A, $4.20 for a set. Bottom line: $4.40 per kit is a great value option that gives this offering a 2 star rating (lack of quality control). As you will see below, high quality fuses cost at least $10 each. Consider these if your application requires higher quality. .amazon.com/PowMr-MC-4-Waterproof-Line-Holder/dp/B08C2JHB6LRenogy 20A Male and Female 20A Waterproof Line Holder with Fuse, $15/single https://www.amazon.com/dp/B00YG2ESN8iGreely 4 pcs.
