why does the unit seem to have TWO sets of wires for the 12 volt source? Do you have to hook it to TWO batteries to get 2000 watts?

My guess is the second set acts as a backup unit for extended run time or if one circuit should happen to fail, the other will take over.

It will supply 2000 watts from onr battery, but it will use up xthe battery very qiuickly - the bigger the battery capacity ((2, 4, or 6 batteries)the lobger thw 2000 watt can be sustain ed. The ibcerter us fullt autimatic abd wilk kick itself off when tgwrw is nit enoufg 12 volt available. But it is good to hook up all four clamps , even on a single battery when 2000 watts of power is needed..
619875
don't know why but if you want to use something like more than 700watt i recommended you use both of them, because 1 wire might get hot and burn, i just dont know why they don't give 4 gauge wire with this unite.
619876
No it's so you can hook to two batteries so you don't run the one battery down
619877
No, you do not. the 2 sets of wires are for different applications. in my case used the clamps to hook up to a bank of 10 batteries charged by solar panals. ut you could hook up to car batteries or RV or other set ups.

I have an additional thought to your answer Kurt. While it may be true that the unit auto switches from 12 to 24 volts for two batteries. If more than two batteries are involved (in 24volt configuration) Additional batteries would have to be by two and in parallell. If you start with one battery (12 volts), just keep adding in parallel. Personally I would just assume hook up one battery at a time ...charge it up fast...then hook up the next one.

Hi Cheryl,First,this panel is only 8.3 watts max.,output.In my opinion it's not enough to take care of two batteries.They do have one that puts out twice what this one can.Both panels use a male cigarette connector,and they supply a female with clamps.If the batteries are wired up in parallel,ie; neg.,to neg.,and pos.,to pos.,then the female cig.,connector with clamps can be used.Just attach the pos.,clamp to the outside pos.,terminal,and the neg.,clamp to the outside neg.terminal.If the batteries are seperate,a double cig.adapter,ie;one male end with two female sockets will be needed.

The inverter requires a 12v source it does not have a rechargeable battery in it. You could bring along a 12v battery and use that as a power source, but pulling 1200 watts from a battery is 100 amps, so it would drain a smaller sized battery in minutes if not less.

the unit is ok 10-to20 volts dc . simply attach it to any like source. it comes with two wires already attached to it . you choose hook it to battery wires or ?.I had two led lights in my rv bathroom , they were very cheap & emitted very little light . I replaced one of them with this unit . Am VERY SATISFIED ,WISH I HAD BOUGHT TWO

The 2 wires are for the monitor voltage and also power the unit. I only tried it at 12V but my guess is their voltage regulator can take the full range of voltage and convert to 5V or 3.3V

I did not use the wiring kit that came with it.. I didn't trust 8 gauge wire with the 2000 watt amp.. I went to Walmart and got the 4 gauge kit and that has plenty of wire in it

Its for two 12 volt batteries hook up for a 24 volt system on a military truck

You would have two wires (I use #10 copper braided wire) coming from solar panel to controller then two wires from the solar controller to battery.

I have had this connected to 2 100 watt panels and four golf cart batteries wired to 24 volts. I have also had it connected to 12 volts on my larger solar system and it works fine although pumps at a slower rate.

See the comment by Gene. Note that if you have only two wires from boiler to thermostat you can't power it from the furnace so have to use battery.

It all depends on how your wires are getting the electricity from the battery bank. If you only have one battery, or one connection point to a string of batteries, you will not be able to pull the full 4000 watts the inverter is capable of doing (for a sub second). I have 8 batteries, and I connect to the inverter from 3 different points in the array of batteries, This is because each battery is only capable of producing so much power. But you need to be able to get all the batteries to put an even amount of juice to the inverter, or you will overload one or two of your batteries. If you never plan to pull more than a few hundred watts on the inverter, one cable will work fine, but if you want to draw the full 2000 watts, you will need multiple wires, in order to carry that many amps.

What kind of charge controller are you using? and how are you measuring the wattage? How long are your wire runs? Make sure you use large wire size....#8 minimum. Are you charging a bank of batteries?

You could have them both connected to the same battery. Each has its own controller.I do not know if you can wire them for any configuration other than 12v....

This unit is intended for use with a 12 volt DC battery. While it is not acceptable to connect two 12 volt batteries in series for this power inverter, it is a great idea to connect two or more 12 volt batteries in parallel. This will provide you with additional amp-hours to power your 110 volt appliances.

two batteries , i could not set it up for the advertized three !!! not sure about the watts .

Output it's 2000 watts, which is at 115 volts, So doing that math, the output amperage is 17.3 however if you are talking about input amps, that's also some "simple" math 2000 watts out divided by 12 volts in = 167 amps
