Looking at the battery terminals on this unit I didn't understand why Aims didn't supply some sort of covers as these things are huge! I called Aimes to purchase whatever it was that I was sure was made and tech support literally told me they had nothing and to just wrap electrical tape around the post. Needless to say I hung up the phone in shock! Can anyone here help or know of covers that are made for these type of posts???

    A roll of 3M electrical tape ?
    Sorry, if covers were made, Aims would have them,   How about caps off a can of spray paint ?

    You can buy "battery lug covers" or "battery terminal covers" It will cover the lug side of things.

    I hate to ask, but Aims is an inexpensive brand and often we see people buying a very high output (wattage) inverter for low voltage battery bank. Hope this isn't the case. Look to buy the proper size wiring for the load!

    666 amps, wow indeed.
    According to the last book in the Bible, 666 is the number, or name, of the wild beast with seven heads and ten horns that comes out of the sea. (Revelation 13:1, 17, 18) This beast is a symbol of the worldwide ...

    If you believe and so forth, nothing serious, just a take on the number, no more, no less.

    So when that inverter hits peak load, the world ends ?

    Maybe something more like fire and brimstone.

    Wow that's just crazy . I like the 1000 w max inverter for 12v rule. Call my old fashion.

    Thinking is difficult, that is why most people judge.

    In my battery business, I see a LOT of 12v systems with 2000 to 3000 watt inverters that have been running reliably and safely for many years. But they are all Xantrex, Magnum and Tripplite systems installed appropriately. By the same token, I have seen some nightmare installations and the resulting fire destruction also.

    People often forget that inverters are constant wattage devices, so as the battery voltage falls, the input current increases. And that an undersized cable results in more voltage drop, which further increases the amperage draw. I always suggest using the current at 10v for wiring sizing, because it can happen. So 3000 watts = 300 amps. So you can quickly see how even doubled up 4/0 cables can result in excessive voltage drop on very large 12v systems.

    Based on working with mobile and stationary applications for the last 9 years, I think that an easily managed limit is 2000 watts for 12v systems, assuming high quality equipment is used. If you really know what you are doing, 3000+ watts is doable, but that level of current requires very specific and special "everything."

    It is ALWAYS preferable to go higher voltage or use multiple inverters if you must stay at 12v for some reason.
