12 volt 2000 watt inverter charger recommendations

............48V at 8000 watts should be good for 3/0 AWG?

Yes. I think you got it. The cables on my inverter are a fair amount larger than 4/0 which reduces the loss in the wires

2000w @ 12v = 200A from your battery. Generally, the cable to carry 200A , won't fit in the connector on the inverter

That is 3/0 cable needed to safely carry 200A, and to do it without appreciable resistance (resistance drops voltage, and the inverter faults on low voltage), you need at least 4/0 cable.

So, the 3/0 cable is the limiting factor. The higher the wattage at 12V, the higher the amperage and corresponding AWG cable required to carry the current. I think I got it.

[FONT=comic sans ms]That is some funny stuff, I don't care who you are. [FONT=arial]Does demonstrate how extremely dangerous the product is if you know what you are looking at. At 5000 watts Input takes 500 amps @ 12 volts. The cable required to do that is 750 MCM which is as big as a mans wrist weighing 7 pounds per foot. There is no way to terminate the cable with the terminals and would require 2-hole 5/8 bolt hole lugs using a 14-ton hydraulic compression tool to terminate.

I'm not a solar expert. Can you help me understand your logic on this? If its unsafe, why are these companies selling these products? Thx.

How about a Victron 12v/5000watt/220-100v/100amp inverter?

Kind of like looking down the barrel of a gun, and pulling the trigger to see if the gun is loaded. One less idiot in the world no one will miss.

Any 12 volt inverter above 1000 watts is junk and a fire trap. Aims is about as bad as they come. The Input terminals are not near large enough to terminate the smallest size wire that can safely handle the 200 amps of current required.

Here is your challenges that cannot be conquered. To run a 12 volt 2000 watt Inverter requires a 900 pound 1200 AH battery with a 120 amp 12 volt charger. Neither of which are made. I would buy a CO2 fire extinguisher before a charger.

2000 watt Inverter is 48 volt battery territory.

Yeah I was pretty sure Aims was junk but I just wanted to confirm.

I put 2000 watt inverter/charger in my last RV with four golf cart batteries and ran it for five years and never had a problem and Battle Born sells two battery kits with 2000 watt inverters but reading through the posts here talked me out of it and I ended up getting a 1000 watt Magnum. The only reason I was even considering 2000 watts was the wife wanted to have a microwave off grid. I told her she has to cook the old fashioned way.

Thanks for the reply.

Can I get any recommendations for a good 12 volt 2000 watt inverter charger? Is Aims junk? What about between the top tier brands?
