Thanks for the review. I do wish you would have answered the one guy's question about the no load Amps, though. I'm wondering about that myself. PowerBright reports

@davegeorge7094 6 жыл бұрын

For computers, TV, any switchmode power device I like to use 90v DC and save switching losses for my off grid home. I only use pure sine for compresors and shunt AC motors and transformer audio amps and other similar type loads. My macbook had powerfactor correction but works on only 75v DC.

What was the power usage with no load on it? Alot of inverters do use some power even when it has nothing hooked up at the output side.

Very impressive inverter for sure. One more question. What is your favorite brand of invertor ??? I just bought a RV and don't want to waste my money trying different ones. Thanks Terry

I enjoyed your review n this product, especially your comment on the capacitor quality... Now it's Sept 2016 do you think they are still using the same capacitors? I am in the market for a 300 -400 w Pure Sine Wave inverter to run a TV in our Travel Trailer off a 12 v deep cell battery... I see the PowerBright still being offered but is there any update or better option on the market today?

Knurlgnar,. I need your help with a power bright 2200 PSW inverter. When powering it up, the over load comes on right away with no load. Please help.

i really like the Accurate tools 300w psw inverter. I can adjust output voltage from 108-130v with no load. It runs at 62.4 hz fans run faster and actually increasing output volts more gives higher watts. most modern electronics have a wide range of voltage to handle 124v or so about where i tuned it at. use it everyday all day for two years in my off grid solar RV office.

I'm not sure an inaccurate frequency is a good thing for most people but perhaps it works well for your application. I'm glad it has worked well for you! I haven't seen good things from AccurateTools myself.

I noticed you really know your stuff I have a question for you I'm thinking about buying a Morningstar sure sine I believe 115-volt inverter as I live here in the states I Will use 115 volt model, I have 400 watts of Solar and 4 golf cart batteries 6 volt each wired up in series and parallel to make one big 12 volt battery basically and I'm wondering I want to watch TV on the weekend while I'm not working and I don't want to watch a small 12 volt set I want to watch one of my flat screens would that Morningstar 300 watt sure sign inverter be a good choice they seem to be well made but I don't know if they're as good as for instance your power bright there, or one of these other brands that sell on Amazon or other places on the computers, the morning star looks good as it seems to be built really well however go power or some of these others might be pretty good too also what do you think of Victron energy Blue solar power inverters, and for that matter their MPPT charge controllers,, I have a Morningstar Prostar PS 30 m charge controller hooked up to my 4 100 watt solar panels it is a PWM charge controller,, , so far I have no complaints it seems to work really well I haven't been using it a whole month yet but it really does seem to do a good job,, I know I couldn't do much with a 300 to 400 watt inverter however I figured it would be more than good enough to charge my laptop and watch television and things of this nature I'm trying to run my lights my router my modem and a few other things on 12 volts DC power I'm also looking to buy a sun Danzer refrigerator and put that on 2 100 watt panels and its own battery bank,,, do you think the victron energy Blue Solar Phoenix I believe 800 - 1200 range inverters that they sell on like Amazon and eBay ,,,do you feel that they're as good as their advertise to be,? well sorry I ask so many questions but I don't often get a chance to talk to someone as smart as you are when it comes to this stuff so I guess I opened up and unloaded all my questions on you hear all at once I'm sorry for that however if you have the time to answer and I would really be thankful me and you make great videos and you really know what you're talking about I really appreciate watch and seeing what you're doing there, regards::: Bill R.

Terry, I am not sure the guy looks at his older posts or not, I asked a question 2 weeks ago and have not received a reply. It would be nice if he did follow up on his posts, this looks to be about 2 years old... I am thinking that technology has changed in 2 years... but it would be nice to hear from the guy..

You gives great information. What would you recommend for a 2000 inverter ? Pure sine wave of course . Something that won't harm a air conditioner, refrigerator .

@knurlgnar24 9 жыл бұрын

Depends on the application but in general I recommend the Cotek, Go Power, Samlex, or Thor 2kw or 3kw inverters.

@SylwerDragon 10 жыл бұрын

One small remark to those caps. They are s. but another thing they are rated only to 85 degree and that is really bad. 105 degree is a must for these closed boxes. I have to say general quality looks good. on some places(smt components) was too much white glue. Chokes should have a bit more glue on it and such but i think it was looking nice.

@curtchase3730 9 жыл бұрын

Great review! Through analysis! BUT...Using standard old Edison bulbs is really no challenge on any inverter. Inverters always shine LOL, using a nice pure resistive load. What makes the conventional mod sine and pure sine units stand apart is how they handle a complicated load. ie: inductive, iron transformer, small motor. I had an Aims PURE SINE inverter, 300watt that looked beautiful on a 100 watt incandescent bulb, but connected a small portable fan and the wave form went haywire. I got rid of it, junk.

@knurlgnar24 9 жыл бұрын

I use resistive loads because they're fair and easy but, yes, inductive and capacitive loads are more challenging for any inverter. This is only 300W and a good brand so I didn't challenge it too much. Also I'm not surprised about your experience with Aims. I agree: Junk.

Hi. I see some of your rewiews because im loking for some inverter. Ive buy two label dispenser from states and here in spain we have 230v 50hz. And the dispensers are labeled 110v and 60hz. They have a small shaded pole motor, only 40 to 70w and an transformer 110 to 12v that power an optic electronic sensor board. The problem is that i dont know wich tipe of inverter i should buy. The pure sine wave or the modified wave? And with how many watts? Thank you. Best regards.

@knurlgnar24 9 жыл бұрын

If you want to power these from 230V then I think you may be looking for a transformer or 'converter' rather than an 'inverter'. Please correct me if I misunderstand.. You can purchase transformers for a reasonable price from many outlets that can convert your voltage into 120V or vice-versa. Just be sure to purchase one that can handle the wattage rating on the nameplate of the appliance(s) you wish to run.

@antoniopop7572 9 жыл бұрын

Yes of course. But the problem here its the diference of the frecuency. The motor is rated 110v 60hz and here we have 50hz. The unit have a small 110v to 12v transformer. Its very expensive and complicated to change frecuency. The most cheapper way its this. The problem its that I dont know if it would run smoothly with the pure sine wave or the modified one? Thanks. Best regards.

@knurlgnar24 9 жыл бұрын

antonio pop My apologies, I replied quickly and didn't consider the 50hz/60hz issue. If the motor is shaded pole then I would expect it to work well on MSW due to the extremely low efficiency of shaded pole motors. The transformer will run hotter but that isn't likely to cause any major issues. I would expect MSW to work acceptable for your application but it's difficult to know for certain. Shaded pole motors don't require a large startup surge due to their inherent inefficiency so you shouldn't have to oversize your inverter by much. For example if the nameplate rating is 2A I would expect a 400W inverter to function for the appliance.

I was thinking the same thing. What good is a 300 watt pure sine wave inverter? Anything that runs on 300 watts or less isn't going to need a pure sine wave.

@abyssunderground 10 жыл бұрын

Efficiency perhaps? A mod-sine is a lot less efficient than sine so you could run your laptop etc on it for longer from the same battery. Also some equipment like a oscilloscope etc uses little power but needs a good power supply. You don't have to think big to need pure sine.

@ElGatoLoco698 10 жыл бұрын

Yeah but it's 300 watts. How much energy are you truly saving? A couple of watts? That's negligible. As for laptops, if you wanted to save battery power, you can buy a 12 volt adapter and skip the inverter altogether. And anyone with an oscilloscope certainly isn't going to be using a 300 watt inverter to run it. I'm thinking practical. I'm all for pure sine wave inverters but I just don't see many uses of a 300 watt pure sine wave inverter. Anything that needs a pure sine wave is almost certainly going to need more than 300 watts.

@abyssunderground 10 жыл бұрын

***** You raise a good point with the 12v adaptor. An oscilloscope is a good example though as there might be a field technician who only needs to run the scope but has no access to a mains supply. A 300w inverter would suffice. I am struggling to think of anything else though...

+ElGatoLoco698 they have a lower no current draw, in the future i intend to have a 600w and a 2000w inverter because of that.

If your only use for the inverter is to power modern electronics, you can do much cheaper and better with a modified sine unit hacked to output DC. Motors will work on modified sine just fine albeit somewhat noisier - the Prius inverter outputs pure sine at low speeds where noise would be very noticeable, but transitions into modified sine at about 30-40MPH as it ends up more efficient overall and any noise produced is drowned out by road noise. ( techno-fandom.org/~hobbit/cars/ginv/VH.html ) Where pure sine really shines is that it doesn't have the standing wave issues when driving long extension cords, but series reactors (power inductors) also solves that problem for less if you don't mind the extra size and weight.

@knurlgnar24 10 жыл бұрын

Modified sine is acceptable for many things but it limits where/how the inverter can be used. EVs do not use induction motors and are totally different animals than household motors. Induction motors need pure sine to operate properly. Modified sine cannot be converter to sine with line filters or inductors/capacitors - it requires an active circuit with all of the associated losses and expense, and standing waves in extension cords is not a real thing. At the low frequencies involved transmission line theory only applies to the long distance distribution network. Think hundreds of miles or km.

@NiHaoMike64 10 жыл бұрын

www.ab.com/support/abdrives/documentation/techpapers/ieee/pcic.pdf The problem with modified sine is the sharp rise times (causes both standing waves and EMI), which a reactor would slow down. Some EVs do in fact use induction motors, the Tesla Model S being the most well known example. Additionally, if you're only running modern electronics, it's a waste to go to AC in the first place since they just convert the AC to DC before doing anything else. It's surprisingly easy to hack a modified sine inverter into a 12V DC to 170V DC converter, which would also solve the EMI issue with modified sine.

NiHaoMike Standing waves do not occur with MSW inverters. The paper is interesting (thanks for the link) but it applies to a different application and is not really applicable here. Any reflected waves die out after only a few oscillations and then are held steady state until the next edge transition. In reality the rise and fall times of the edges on inverters I've seen are quite slow and transmission line theory can be fully ignored for practical purposes. It is interesting that Tesla uses induction motors - they must then use a sine output from a dedicated VFD. These are inverter duty motors, of course, and constructed differently from a household induction motor. I'm not sure the PFC on all SMPS will happily accept DC? Given that most of the losses when powering switch mode power supplies are on the boost stage of the inverter I'd just use a MSW inverter as-is. Interesting idea though and I haven't thought about all of the possible implications of doing so.

I bought a power bright pure sine wave 600watt con. for my solar generator I built iv had no problems with it only used it 3 times though I ran a big laptop tv and xbox all at once with it my fan is temp controlled and I paid about 300$ for it later on when I built a separate but big solar generator I will be looking to buy a power bright 1500+ prob more pure sine wave inverter i have 2 things for back up my 600watt pure sine solar generator and a harbor freight solar panel kit for lighting and it is able to charge a few little things as well so when the power goes out or cant afford the bill I can always have power I got into building my own solar generator a few years ago since I built one better than others iv seen and for about 500$ cheaper my batteries I got are 122amp hour deep cycle batteries from Wal-Mart I paid about 85$ each for 4 I picked them because of the 2 year warrantee but I bought an extended 2 years for only 10 more $ each free replacement I think iv done a good job for someone that has no back ground all I did was watch a lot of youtube vids and looked at many reviews some of which were from this channel thanks for making this video
