looking to use something like this to turn on and off a 12vdc to 120vac power inverter when the batt. bank runs down, is the kick in point adjustable?

Out of the box the adjustment will not give me the range of voltage that I wanted. It has to get to around 10 volts before it will kick in. I did not want my batteries to get that low. This could be changed maybe but I have not had time to play with it.

Yes, it is adjustable. Be sure to read my review on this product. Unless they have resolved the problem, the wiring is backward as described in the instructions.

No adjustment available on this unit. You might consider installing a current limiting resistor on the output. Great unit with such a wide range of input I use it with a solar panel and packs of spent alkaline batteries for phone charging.

Hi. I can only assume that your question is due to the country you live in. If so, i must admit that i bought a power step up and step down box. This was to make sure that if I got the voltage wrong, it would not matter. It was the safest way. The actual tool works perfectly.

If your batteries are connected in series to give 24 V DC, I would not recommend that you use this inverter because it is meant to be used with a 12 V DC supply. Instead you may want to find a 24 V DC to 110V AC Inverter such as the "Power Bright ML1500-24 1500 Watt 24 Volt DC To 110 Volt AC Power Inverter". Amazon has this product also. If in doubt, have an electrician assist with the installation.

for sure. or you can use a controller that changes it back to 12 volt. controller is key either way

It is adjustable. I have 10 of them and I have set them to different voltages.

I used a standard car battrery and it ran a radio 2 40 watt lamps for days before needing a charge. Make sure you dont get poitive and negitive mixed up. It killed my inverter dead.

Depends on the amperage of the inverter and what you are trying to power up. Anything that is high draw should have a dedicated circuit right to the battery. I wouldn't even recommend a high amp or watt inverter be plugged in to the factory outlet let alone an add on.

I think the manufacture should clarify this issue. four wires from one battery bank or two wires from each of two separate bat. banks or can you use a jumper to connect the the studs on the inverter ???? {buss bar}

not sure, i use to turn on/off a 9volt battery. Im not technically an electronic master. Sorry man.

It is adjustable but you will need a voltmeter to adjust it to the needed voltage.

im not really sure of the layout your talking about. but this usually kicks in when the utility power shuts off. If you want instant power switching i would use a dpst contactor. They are cheaper and instant power switching. You can hook the 120 to the coil from generator and when the generator is supplying power it switches to itself and when you shut off power it will go back to your solar bank. These range from 20-60 dollars and are dead simple to install.

This unit works awesome! However, it operates on 110 VAC. Because it have a low wattage draw it may be possible to rig a 12 VDC battery to an AC power inverter. Even better would be two 12 VDC batts in parallel with an inverter and solar panel to keep them charged during an extended power outage.

Most of these have a "low voltage alarm" and the power inverter may automatically stop functioning, but other 12V items (like something plugged into the lighter socket) will not be stopped. So you need to monitor those items and turn them off before it goes too low. FYI, I've seen on battery distributers websites statements like "Draining the battery to 0V just one time can make it no longer hold a charge", so once it seems low stop running things before it gets that bad.

What you seek is called a "Voltage Stabilizer (or Regulator)." This is a far more expensive device as it requires the use of batteries to give electricity when it dips, or store electricity when it exceeds. This unit does surge suppression, EMI rejection, and the will MONITOR incoming voltage and will "Boost" input voltage if it dips to an unsafe level, and will "Trim" the input voltage if it gets too high.

No. It only converts DC power into AC power. The batteryour is your electrical source.

Not automatic; there's a little switch accessible from the bottom, that you'd use a small slotted screwdriver (or maybe a tiny key?) to move to either voltage. It's small--wear your glasses, if you have 'em. For myself, I'm glad it is a bit of a bother to do it, since I don't want it to un-adjust by accident. My guess is an auto-adjust feature, in addition to being risky to depend on at odd times, would raise the price above what I'd prefer to pay. Hope this helps your decision.
