Pure sine inverter

Anyone here has any experience with a pure sine inverter? Is it worth buying it instead of Off-grid inverter? Which brand?

Pure sine is referring to the AC waveform supplied by the inverter. I'd recommend a pure sine wave(PSW) inverter regardless what type you buy.
Off-Grid means not connected to the electrical grid. An example in the photo I attached, don't mind the extreme organization ?
What's your intended use?

Are apples worth buying instead of motor oil? Pure sine is a subset of off-grid inverters. Grid-tie has different criteria.

This link has a number of pure sine wave inverters that can be used off-grid. The Samlex brand is hard to beat for the price.

I have purchased a couple of inverters from Don Rowe with no problems. They are known for good support.

Most modern electronic controls do not work well with MSW. My microwave needs PSW. I have Samlex 2000 PSW from Don Rowe.

I would not consider using an MSW.

I use the SAMLEX inverter, the PST model. I use a 24 volt 3000 watt SAMLEX PST 24-3000, and just pulled out a 12 volt 2000 watt SAMLEX PST 12-2000 inverters.

Pure sine wave inverter is very useful for me, I use my printer with it on car.My inverter is VOLTWORKS 2000W Pure sine inverter.
Maybe you can tell us why you need a inverter,or which appliance will run by the inverter?

Some inverters will not send power back to the grid or can be connected to the grid.

No matter the wave form, Pure or Modified Sine Wave, some inverters are Low Frequency and some are High Frequency and IME, High Frequency will not start or run all types of motors, such as those with high surge starts such as some vacuum cleaners, microwave ovens, or a well pump, or an air compressor, etc., or "high induction loads".

So you need to decide on what your present and future appliances need for start up power surges, your budget and your on or off grid needs before deciding on a Low or High Frequency, Pure or Modified Sine Wave Inverter. And many manufacturers of especially High Frequency inverters do a poor job of telling you that and just what the inverter will actually power properly.

Search the forums for past threads on High Low Frequency Inverters as well as Pure or Modified Sine Wave. Or for Grid Tied inverter if your inverter will be connected to the grid. Also search YouTube.

Low Frequency Pure Sine Wave inverters with correctly sized cables (large enough or larger)) and a battery of large enough capacity for your appliances used, in general, is the best or most versatile type to have. From what I understand.

Being able to be Grid Tied is another criteria to add if required.

Also does your needed inverter also need to have a battery charger built in?

I think that this link to "Roarbatt" inverters is EXACTLY the problem I was referring to in my post above, where a "supplier" does a very poor job at explaining what their inverters are and what appliances / loads that they can run and what kind of power is required.

If you read the hype, it seems that they can do all and run all appliances with no mention of the input power required. To me, these are exactly the type of inverters and supplier to avoid unless one knows exactly what the inverter one is looking at will do and how it is built.

To me, they look like the same cheap high frequency inverter that are a dime a dozen but which will have compromises and or a short life and not run all loads out there. Some seem to have the same logo or label pattern as the Xija "brand", or is likely just a rebrand of inverter XYZ. A friend had such a high frequency Xija, 3000 watt "inverter", that would not run a vaccuum and caused the LifePO4 battery BMS to shut down and also caused incredible anxiety and stress for the owner as neither the Chinese inverter nor the Chinese battery explained what the hell the problem was and did not provide error codes to troubleshoot. And yet Xija, like this Roarbatt doesn't mention any info on what exactly it can or cannot do, other than make your life wonderful. Well the Xija sure did not and I expect the Roarbatt to also have very limited applications.

As for brands to actually recommend, the original poster needs to provide more information on what appliances / loads that the inverter is to be used to provide power to and from what source and the source type(s), the set up (cabling at minimum), the budget, does it need to provide charging, etc.. Then something like the very vauge and "incredible" Roarbatt might be a recommendation, though other than for very light use, I wouldn't touch it with a 3 meter pole and I would run far away from high frequency inverters in general.

The BS with inverter sellers is the lack of information . No inverter can do it all unless one is willing to pay a lot of money for it to have the features to do so.
