EPEver SHI400 Pure Sine Wave Inverter – 12v Solar Shed

a couple of weeks ago I decided to buy the shed a little treat but when I say little hmm it barely fits on the bench here so we best get out on the box so even out of the box I’m struggling to get it all on the bench but as you can see this is an EPever SHI400 pure sine wave inverter and apart from a couple of pieces of packing foam and their certificate of quality control this is everything you get in the box a user manual and the device itself and now we have the inverter out of the bag we can see here on the left-hand side we’ve got the DC input which is ten point eight to sixteen volts this is a 12-volt pure sine wave inverter and I guess a cooling fan is in there and on the right hand side we have a universal socket here which is protected with a gate doesn’t need the earth as it would usually in the UK to be connected to move that gate but at least there is something there we can also see we’ve got three LED indicators here the input level at DC input the load level web that’s okay or overload and a fault light as well the three dip switches here allow you to change the inverter from 230 to 220 volts 60 to 50 Hertz and SAV stroke NOR now I’m not entirely sure what that is we’ll have a look at the manual an on-off switch a remote on/off switch option as well here and finally in rs-485 port because this is compatible with a number of the accessories in the EPever solar charge controller range so first things first I want this to be european standard 230 volts however i think before we turn it on we need to have a look inside don’t you so I have removed four screws and we can see the case is coming apart but now I can see that this top aluminium extrusion here will come off so actually I only need to take the top screws off the other side so now with six of the eight screws removed the top removes and the good thing is I can’t see any floating components or anything awry in there straight away on the left-hand side the input side here we can see this cable how thick is that so unfortunately we can’t see the markings on the cable here but this is sixteen millimeter squared and it’s slightly shy of that I would suggest and put still a hefty piece of cable the positive goes straight into the mainboard here whether our two thirty amp fuses and I’m guessing they will be in parallel to give 60 amps total and we can see the large transformers here in the middle and at the bottom some MOSFETs I’m guessing which are bolted onto the side of the case as is this small heatsink here and there’s some more MOSFETs there at the top there’s a daughter board down here which presumably is all the control software as some sort of microcontroller it looks like under there there’s also a buzzer presumably to announce of low voltage and then finally we’ve got the little breakout board here for the LEDs and the rs-485 port the mains obviously out and then if this here a little thermistor attaching here to the heatsink and those MOSFETs for over-temperature protection the capacitors down here are all rated for 25 volts a little larger on here is actually a 500 volt capacitor so all in all so far I’m quite impressed with a build quality this unit so before using the inverter you need to read and save the safety instructions so I will read most of them this manual covers three different models the 400 which I’ve got the 600 and 1,000 watt inverter it claims a wide DC input voltage and low harmonic distortion there’s an energy saving mode LED indicators and the output voltage and frequency can be changed it’s got extensive protection short circuit overload under and over input voltage over temperature and inverters in a fault identification protections and it can continually operate at full power which is good to know so the 12-volt version will work well 10 point 5 volts to 16 volts is what it said and that LED will change color green is good low the level again orange is a low load Green is a normal load red is a large load and blinking is over load there’s a fault status LED as well that does various different things and the buzzer sounds for various different reasons now although I’ve bought the 400 watt version it will actually do more than 400 watts look it will do 200% outputs 800 watts for 1.5 seconds so if you’ve got a load which takes a large draw to start up something like a motor then this will provide up to 800 watts for 1.5 seconds and then you better make sure that motor draws less than 400 watts after that 1.5 seconds and this is the bit I need here for that last dip switch the mode switch or the saving mode when the switch is on the saving side the SAV side the inverter will enter a saving mode it will shut off the output if the load is less than 20 VA so I need to turn that off I think for my initial testing and finally I think this little circuit here explains the external switching of the inverter and I’m going to install a new DC breaker here this is a 63 amp 125 volt DC breaker here and the reason I’ve gone for a 60 amp one is because if this goes over current a little bit for a while well 600 Watts for example divided by 12 volts well very roughly that’s about 60 amps isn’t it and this can of course go up to 800 so I needed something a bit beefier so have to turn the inverter round here to connect up and these wires aren’t live at the moment 16 millimeter squared cable going in here that should be man enough and positive and negative and I think 16 millimeters is about as wide as we can get into these terminals okay so I’ve connected up the cables let’s turn on the DC breaker and turn on the main switch there was a beat there in the fan spun for half a second and now we’ve got three green lights on the front well that seems to be working let’s plug in the meter now I’m expecting there’ll be a few of these funky angles in this particular video but there we are 229 volts and that’s running at hmm forty-nine point nine Hertz and that’s pretty good and it’s worth just looking at the no load current I’ll just zero my meter clamp it round there there 657 milliamps and we’ll just put a small load on here I’ve got a 40 watt incandescent lamp on and if we turn that on its remaining at the same voltage there so we’re pulling just point for the lamp 42 watts for my lamp there and well the frequency of that signal is holding up nicely too and the last thing I want to do is compare the EPever SHI400 pure sine wave inverter with my old modified sine wave inverter so with the oscilloscope plugged in let’s turn on the modified sine wave inverter apologize for the noise in the background but look at that square wave there and that’s not what I’m hoping to see on the EPever so there we have it the EPever pure sine wave inverter does seem to be a pure sine wave but my goodness is it making my oscilloscope go a bit crazy so there we have the EP ever shi 400 pure sine wave inverter and I mentioned earlier that it works with a number of the EPever solar charge controllers accessories and it does it works with the official rs-485 to USB cable it also works with the e box Wi-Fi oh one and there’s no reason why it shouldn’t work with my homemade USB cable but perhaps we’ll save that for another video the unit seems to be well made it is creating a pure sine wave the 600 milliamp no load current I think is pretty reasonable and the fact that this will do short bursts up to 800 watts is very useful on reviewing the video it seems this inverter is quite noisy not on the sine wave output itself but some of this electronics in here is making an awful lot of noise it was picked up on my microphone and also it was clearly causing my oscilloscope a few issues hopefully that’s not going to cause me too many problems I’ll leave a link for this item down below it only seems to be sold on eBay by one seller at the but they are open to best offers hopefully you’ve enjoyed this video if you have give me a thumbs up subscribe down below comment if you can and I’ll see you next time thanks for watching

  1. I much prefer those dc binding terminals to the "thumb screw" types on most of those small inverters. could you hear the noise or or did you notice it while reviewing the video?

  2. Wow Adam whats all the noise…..That needs investigating is it blasting out RF noise thats getting picked up by the Camera lets us know if you manage to tame it…..Nice video again pal

  3. I like a solid inverter. It must run 24 hours a day i like Victron that a dutch brand

    I use here all more than 12 years a 24/800 watt inverter 24 hours a day.

  4. I have purchased a number of inverters from these guys, and they are excellent:- http://www.ebay.co.uk/usr/reliablepower

  5. Hello Adam…good video, congrats on the inverter.  Have you considered, the "floating" Earth in the shed…?   Your inverter can "float" at half the Vout…  causing trouble for the scope and mic.   The sound you "hear" can be the missing ground…picked up by the cables, working as antennas.   Much like, when you use some  laptop or pc's in a two prong socket, floating, without proper ground.  Just an idea and a thought.   A piece of rebar or better, hammered in to the ground, will act as ground.  Is there a "Ground" on the scope…?   if so, is it making any difference…?   Good luck investigating…!   PS: I know the shed is 12 Volt, but this could be a new situation.

  6. To avoid import tax just write seller before purchasing and get him to confirm an outside value of no more than 10 dollars.
    For heavy shipments get him to mark it as "generator sparepart" or similar 😉

  7. Here is the Aliexpress link for it. I think its the official Epsolar reseller. 147 dollars with 2-4 days TNT shipping included.
    I purchased from them several times. Very helpful and so far i haven't paid import tax on any purchases, not even the 3 kg 4210 Tracer A shipment, i just get them to use a low value 😉 Shipping with TNT takes takes 2-4 days from China to Denmark.
    I highly recommend this seller

  8. I was just looking at these the other day! look forward to seeing you connect it up to the software and hearing back from EPEver. i think a three part series could be in order! 😉

  9. Hi Adam. Thanks for your inspiring videos. I'm fairly new to electronics and solar. Is this product different to a Grid Tie Inverter one of which I use to put surplus solar energy into my mains?

  10. Hi Adam Thanks for the review on the EPsolar inverter. Did you get it from Ebay ? bimblesolar uk are the agents for EPsolar by the way. You state that the inverter must be earthed. pls expand on that. I am looking forward to hear what EPsolar say about the noise

  11. Hi Adam, that "audible" noise would probably be "heard" on RF too. As a ham I am looking for a good, clean 12v solar shed/shack setup. The EPever Tracer A is flamed on Amazon by radio amateurs and boat owners being extremely RF noisy. And now this inverter.
    Seems that EPever isn't really bothered keeping their products RFI "clean". Pity, I'll stick to the bit expensive blue coloured stuff that boat owners use.

  12. A Chinese inverter that lives up to it's claimed capabilities? Wow! It must be a special day for the shed. ;-p Thanks Adam. I'm looking forward to hearing how it performs over the next couple of years. As for the oscilloscope glitches, it's probably RFI which is coming down the output leads, or possibly being radiated from the unit/ input leads.. First step would be to try adding ferrite rings to the input and output cables. Screened and grounded cable might also help. Another step would be to move the inverter as far away from the 'scope as possible. I once had a professional RF signal generator which only worked properly with the manufacturer-supplied screened and grounded mains supply cable.

  13. My Latronics 400 watt inverter ran a 1600 watt vacuum cleaner for over a minute. Then it quietly shut down. But that's made in Aussie, not in the PRC. Nevertheless, these EPEver inverters look pretty good. Maybe you could even get your lights off the grid with it eh Adam? 🙂

  14. Thanks for the review it's come at a very timely point for me. I'm thinking of setting up a small test system to run my home workshop off-grid. I have a milling machine rated at 500W but run it for only relatively short periods of time maybe 5-10 minutes total in any hour. I wondered what size of inverter I might need for this – 1000W maybe or could I get away with something smaller?

  15. I have the 1000W 24V version. It is electrically noisy, and causes problems with my arduinio control system which is nearby, articularly one wire DS1820 temperature sensors A cheap PWM battery charger I have does the same trick so its probably as much my system as anything. . The power saving mode can cause problems of its own too. My deep freeze has a real downer on it, when its first powered up the freezer draws a lot of power for a couple of seconds (about 800 watts – 40+ amps )and it cycles every 10 seconds. It completely negates the saving gained by turning the inverter off for most of the time. My fridge has no such issues. On the plus side it has no issues starting the freezer or the fridge. I dd size it working on 7-10 times running power to get it to kick up.

  16. I have just bought one of these to compliment my epsolar charge controller. i cant get the monitoring to work.
    i have the ewifi box which works fine with the charge controller.
    I have read the manual and see that it needs to be ID 3 unlike the charge controller which is id 1.
    I have download the correct software.

    I dont have a android device so i use the windows software and the virtual com port.

    In the video mention it worked with the ewifi box but was that with your android tablet or virtual coms port and windows?


  17. hi Adam Welch
    i have a EPEver SHI600 inverter i ' d like know if you can demonstrate how can i utilise the remote ON/OFF switch because its not a simpele ON/OFF switch i suppose ?
    also i hope you can do a video about using the eBOXwifi to configure the inverter
    thank you .

  18. Adam, great reviews so far, a fan from another 'experimental techie' from indonesia. Just wondering have you done a "Cheapest On-Grid Inverter" review already? I guess this piece is the only missing review that makes a solar newbies out there would expect from you. MPPT function, Pure Sine Wave and 85-89% conversion power rate are few claims that I would think you probably the best person to prove it. I could point few inverter candidates for your review 😉 Anyway, just a thought, love your work so far and keep that British accent!

  19. Hi Adam, I've been following your solar meanderings for a while now, and bought stuff after your reviews. I have finally got 'the shedifice' power-station up and running, with 6x 190w mono's, a 4210A, 2 x 120Ah tank batteries, and finally ordered an Epever STI1000-24-230. (The sterling 24300 pure sine gave up the smoke). Quick question: is there a preferred orientation for mounting the inverter, and which way does the fan blow; in or out?

  20. Hello Adam , thanks for good video, can you recommend this inverter with 1000w ? I need for few led lights , radio and fridge 0.31 kw /24h , i bought epever mppt A30 after I watched your video , thanks advanced

  21. Some of the pure sine wave inverters produce very good sine waves. I have three from Reliable Electric (two 2000 watt, on 500 watt) and both deliver a cleaner waveform than the electric co-op that serves our area. The Ebay vendor ID is reliablepower I've tested all three units at 80% of their rated load (which is more than the working load in my application). They still have the same waveform and they meet the >=85% efficiency up to about 80% of rated capacity. They have units available in all input (12, 24, 48, and up) and most common output (120, 240) voltages.

  22. I use the green 3.5 mm Phoenix connector on a relay to turn it on and off using a battery level checker, set to min 12.0V and 14.5V re connect.

  23. Hi adam
    Thanks for your best review
    I want to buy 2000 watt inverter, do you recommend this brand: epever ?
    Because this brand and many off other brands does not have any guarantee service in my country. And before buy i want to be sure this is a good one to buy

    Sorry for my english 😄

  24. I was thinking that there was a reason for all that Silastic gunked up on that one transformer. I'm sure that's the culprit, they were trying to reduce the noise. Was a pretty high frequency too. It's probably creating the sine wave out of high speed pwm switching. That's the only way to get the high efficiency that it claims. The noise isn't a problem unless you have to listen too it. Put it inside sound dampened enclosure.

  25. There are a number of issues that cause this electrical noise.
    1-The switching transformers are most likely not wrapped in copper shield, and grounded to Earth.
    2-The ends of the aluminum enclosure, are plastic and RF goes right through plastic.
    3-The output is still somewhat digital. @9:46, you can even see the little steps. it looks like 80 steps for one cycle.
    install another ferrite choke like the green toroid already installed, and pass the wires at least twice through it, along with a class
    X1 and Y2 capacitors, should help with noise attenuation, output smoothing and filtering.
    Also, the reader should consider building one, using a "EG8010 + IR2110" driver module from AliExpress for < $5
    Or a complete kit for < $60 that uses that module as its brain box. (Search AliExpress for "inverter pure sinewave 1000w").
    You'll have to place in in a box. I would use an old computer case.

  26. I have an EPEver solar system….XTRA4210N….is working fine and not much RF noise..my Pure Sine Wave 600 Watt inverter from the Brand ES-series direct on the 12v  AGM battery,s is making a terrible RF noise on my Hamradio Bands..especially 160 m Band is about 1.8 Mhz…..its so terrible that we cannot work on that band…i guess the same with this EP Ever inverter…no priority for these Chinese ( sometimes junk ) inverters to filter the output with Torroid ferrite  cores and Elco,s  etc… … buy an SMA  (  German made ) and its fine….. 73 ( Greetings in Hamradio )  Gerben PA0GDW The Netherlands
