![]() ![]() Of course, make sure that 110VAC cable is SAFE from chaffing etc. You may overload the inverter momentarily starting up a large load and you don't want to be replacing fuses all the time.Īnd yes, if you want to run say 30' from the battery to the AC load, then having the inverter 12V input closer to the battery is more efficient in terms of voltage drop on the 12V side (due to much higher input current) and run the long/extension as 110VAC. Personally, I'd use a circuit breaker rather than a fuse for an inverter. Anything else that can run on 12V, run it direct. The only reason to have an inverter in a vehicle is to run things that can ONLY run from 110AC. It has NO advantage for your use in a vehicle. You will lose power in the conversions due to efficiency losses.ĪC has a simple advantage in power transmission lines that it is relatively easy to step up to 300k VAC or more so that resistive losses over long haul (city to city, across states, across the country) are less. 750W output will be more like 820W input assuming ~90% inverter efficiency.Į.g., if your fridge can run on 12V, do NOT convert 12V DC to 110AC to run the fridge via the AC input. Some of you folk are ignoring or not aware that there is power loss involved going from one voltage to another, be it a DC : AC, DC : DC, AC : DC or AC : AC.ĭon't convert voltage or AC/DC unless you have no option. This thread is funny - in a non-technical way The new 24 pin connector added one line apiece for ground, 3.3, 5, and 12 volts. ![]() The older 20 pin main power cable only has one 12 volt line. So the relevance to what you are doing is, in regards to AC, is zero. The 24 pin main power connector was added in ATX12V 2.0 to provide extra power needed by PCI Express slots. (Although if electric cars catch on, Edison's method will become popular also." from high to low voltage so that the high voltage did not have to go into the home, he won. Once Westinghouse was able to transform A.C. Westinghouse argued that requiring people to transport wet-cell batteries (like automobile batteries) to have them recharged was dangerous and difficult. Edison maintained that running the high voltage into homes would be too dangerous. which could be generated in a central location and then sent by wire to individual homes. power with every home having a bank of batteries, that they would take to a central location to have recharged, to run their lights and so on. There are tons of articles about but if you REALLY want an interesting read: īasically: "Edison originally advocated purely D.C. ![]()
