How many battery do I need to hook up?

It depends on how long you want to use the power inverter and how many watts per hour you are going to use and will you be charging the battery at the same time or just use a battery without charging .The formula is (amps x 120 v = watts X hour) amp draw should be listed on tag by the model number

You must have 2 batteries. Both need to be connected directly to the posts. You cannot run the batteries in series.

Try 4 Marine batterys the biggest you can get ahold of locally (avoid shipping)

I use a 9v battery. You will need to adjust the battery connectors a little, as it tends to be a little wide.

Hooks up to a 12 volt battery. You'll need a pretty good size battery bank if you want to run a toaster. 200 Amp-hour or so. Then you plug in your AC appliances, and turn them on. Mine blew the internal fuses when I tried using a vacuum, guess it was just a bit too much. Bit of a task replacing them, so will probably add fuse holders when I do it. Otherwise it's a pretty good unit. You'll also need some pretty large cables from the battery to your unit. Along with a 150 amp fuse. Good luck!

Yes, as long as you don't exceed 2000 watts. If your gonna use more than 300 watts then hook it up to a battery.

require 2 batteries but you should have 4. 2 spare and charged in case of emergency.

the battery is for backup only..... in case electricity goes out. You still need to wire it.

Just one. I would not recommend. The charging system does not have a regulator and wrecks the battery if left charging too long. I've gone through 3 batteries and while they are not that expensive and easy to replace, it is a major pain. Only problem with it really. It sounds ok but the battery did last very long when it works.

That depends on the load you will be using, just a radio, lights, and a drill only need 1 battery, powering a 900w piece of equipment you will need more batteries if you are going to run it for more than 30-45 mins.

Yes. You will need one a least. Six or eight is not out of the question either because, this will give you more electricity into the evening hours.

Yes: you can hook up as many 12v batteries as you like. We have many of these with up to 4 batteries connected. IMPORTANT: If using 12v batteries, just be sure you hook them up in parallel, not series!!

How many batteries depends on what you plan to run and for how long. Don't bother with anything bigger than 14 AWG for the 120V side.

It NEEDS two, but has space for four. Minor difference in brightness running on only two batteries. I imagine the run is less on just two.
