600w Inverter won't run 1.2a chest freeze?

I do not know if my "method" applies to your freezer but I had a similar problem with my Dewalt saw. Every time I started the saw my generator stopped with the overload LED lit. Then a friend of mine told me to use the longest extension cord I had between the saw and the AC outlet. I connected a 25m (about 82 ft) extension cord and the saw started without the generator giving up! I guess this will only work if your inverter is slightly under-powered.

At this point it's worth a try. Either it will work or it won't. Idea is the resistance of the long cord will reduce the heavy surge. The question is, will it reduce the voltage too far as well, and would the inverter still have enough guts to get things going. Give it a try.

Re: 600w Inverter won't run 1.2a chest freeze?

update us when you put the new inverter on to be sure it fixed the problem.

Re: 600w Inverter won't run 1.2a chest freeze?

Not sure if I should start a new thread, I know this subject gets brought up a lot. However, this seemed to be the closest in relation to my question. Ufortunately, the OP never followed back up to let us know if his new inverter solved his problem.

I just purchased a 5.2 cu. ft. freezer for my future homestead and I wonder if anyone could recommend an inverter that might work well with it. I'm not sure exactly how much start up voltage/current is, I don't have any meters that can catch the in-rush current quick enough, but I know the cheap 300W 12V inverter in my truck doesn't work. My Kill-A-Watt and some other multi-testers I have are showing between 74W (0.74A) and 84W (0.84A) when the compressor is running.

My system will be a lot like Cariboocoots in PV size and battery bank size.. My bank will be be at 225 AH 24V. He uses an Outback 3524 but I just don't know if I can swing that in the budget especially with only the freezer on the inverter. I'd like to stay in the $1000 range so that puts me into the category of something like the Magnum 1800W 24V Modified Sine with Charger. What do all think?

You can get a Outback GFX 1424 Sine Wave @ 24 v for around $1,000 + $200 Mate. It has 1400 W with 2800 W Surge. It'll give you Generator Support and a whole lot of flexible charging capabilities.

Thanks, I'll add it to my short list. I've also just left a message for an electrician friend of mine to see if he has a meter than can capture the in-rush so I know exactly what I am dealing with.

Avoid any MSW inverter when you're trying to run a motor; it just makes matters worse.

Ok, seemed to make sense to me, but I thought someone mentioned there was an issue with pure sine wave inverters. I am likely wrong, and so are they, information overload is terrible on this subject.

Re: 600w Inverter won't run 1.2a chest freeze?

Yeah Coot. I'm hoping my friend has a meter that can capture the in-rush so I know what I am dealing with. I am quite pleased with the operating current, I just want to buy the right inverter from the start.

I'm pretty sure that one can take the low level voltage output from a clamp-on AC current probe and feed it into a sound card on a PC (line in) and then look at it with free software such as Zelscope. But I haven't tried it (I have several real oscilloscopes). Calibration could be done by comparing it to a steady-state Kill-A-Watt reading.

I know that MidNite sends their products to get ETL approval.

Check with your insurance company... it may mean that they don't have to pay a claim on a house fire if they think your equipment caused the fire.

So many May's and Could's in this world. The same Could be true if you install a Solar Panel on a roof without a structural certification from a Qualified Structural Engineer. The operative words being Could and Qualified, Check with your insurance company.

And it's all about the insurance companies demand to have someone they can blame for anything that may or could go wrong - - - so they won't have to pay a claim. And if by chance (horror of horrors) they DO have to pay, they know who they can go after to get their money back.
I really don't know why I pay for insurance - - i know they won't cover me if there's a problem. In the meantime they just keep taking my money.

I won't buy any Insurance from a company that uses their own employee Adjusters. I look for companies that use outside Independent non-employee adjusters. After many years of dealing with them , you'll come out the best.

From someone that actually manufactured equipment with a UL and CSA certification, it's all a racket for someone to make money off someone's else's effort. All the certification people are bitter competitors and play games with each other. AHJ's all come up with requirements based on what ? The standard is that there is no standard, your just at the whim of your location.

Well you have to play the game with the insurers. I had a pretty good hail storm a couple years back and the insurance company was actually pretty darn good. My house hadn't been painted for almost 10 years, the hail damage the paint to the point of knocking it off the stucco exterior. The painted the whole house.

My new building had green stucco on it at the time, they fixed the stucco and repaint the whole building.

The screens on the house got damaged, but they were 15+ years old, they replaced about 75% of the screens.

My solar panels were inspected by a external vendor to see if there was any damage to them, lucked out there. But when I installed them I informed the insurance in writing (including photos) about the cost and value of the panels. I did the same on the new building, come to find out no rate increase as one out building was already covered.

All 3 of my cars got damage, they repaired all 3 cars.

Yes there was a deductible, but that is always a balance between payment and risk.

BTW they just gave me a check and I got to negotiate all the repairs, there check actually covered everything and my deductible was unneeded to be a contribution for the repairs.

After all that no hike in rates, which is understandable as they were still break even (or ahead) compared to 15 years worth of premiums.

I have to say generally top notch companies give top notch service.

The inrush current will be about that. A1500 w SW inverter will be adequate providing its not also supplying power to another high continuous current device.

Re: 600w Inverter won't run 1.2a chest freeze?

I'd do all you can to reduce start up current and then size the inverter. Big inverters tend to be inefficient at low loads (like .85A).
