Pure sine wave inverters (1 Viewer)

[alia176]

I talked to the AIMS engineer (tech support) and he said pure sine. I seemed to know what he was talking about.

The furnace is a 24V unit DC motor.

I am known to do thorough research before I actually buy or take action. I know that my furnace is not typical and I want during emergencies to run it off the truck, and use it otherwise for the normal inverter useage.

I'm curious, is there no other solution other than a Inverter for this particular app? You're going from DC to AC then back to DC for the furnace motor which seems inefficient to me IMHO. Maybe I'm mistaken.

Is it not possible to series two 12vdc car batteries temp just for this type of emergency? Suppose you have a dual batt system in your 80. Is there not a gadget that can turn the parallel batts into series w/o adversely affecting the vehicle's electrical system?

I thought I read somewhere people are using their dual batt system to power a 24vdc winch. I can't recall what kind of gadget they were using to do this however! This wasn't in a Japanese 24vdc diesel Landcruiser but over here in the States.

Since the furnace is converting 120vac to 24vdc and it's just so happens that a vehicle alternator is capable of producing 120vac directly, I wonder if this can be utilized somehow. Maybe one of those onboard welder like Primier power welder or Mobi-Arc can help out?

Just thinking out loud.

Cheers.

My guess (educated one) is that the furnace uses 24 VAC and draws little amperage, less the indoor fan motor.

For about $35 dollars you can purchase a device called "Kill-a-watt" meter. It displays ac volts, amp, watts, HZ and totalises your KW+H. A very useful tool.

HI,
I am looking for feedback on pure sine wave inverters in the range of 3000 to 5000 continues power.

I am looking at product from Xantrax and AIMS. Any feedback on these two company is greatly appriciated.

The purpose is to install it at the back of the track and connect it to the house power in case of emergency, or to use it in the field.

Buy a back up generator and have a qualified electrician and install a cut out box.
Otherwise just plan on camping out. We have a Honda generator that will keep the freezer going if the mains fail, other than that we could get by with the gear we have.

First off I'm not a residential electrician, I hang out in the industrial world, but I am thinking that most furnaces just need a single pole 120Vac feed and from there it has a control transformer to knock it down to 24Vac control and the main fan/blower motors are usually single phase 120Vac motors.

If my power goes out I am thinking the main loads I want to have supplied are my refrigerator, deep freeze and the natural gas furnace. 3 loads and all single pole 120Vac loads.

Rhyary Perhaps you need to confirm just what supplies your furnace at present from your lighting/breaker panel board.
The furnace should have a tag on it as well with what power supply/feed it needs.
just my 2 cents
