EG4 Chargeverter Teardown & Overview 🔌 Testing the Capabilities of the EG4 Chargeverter!

[@craigbourgeois437]

Thanks for tear down mine did not have glue and one of the boards was out of place causing it to only put out 50 amps

[@joshg1244]

I wish these existed when I built my first system as I would have moved up to 48V (small system) I also wish they made a 24V & 12V versions

[@colormaker5070]

Great timing I was just about ready to make an adapter plug for use on 120VAC. With Idalia at my doorstep it will get a good workout. EG4 nailed this design it was like they read my mind on what I was looking for in a high current charger.

[@CurrentConnected]

Glad we could help, and stay safe!

[@AdamDeLayDIY]

Thanks for sharing! I didn’t know they modified the unit to slowly ramp up. The original units used to just discharge full power as soon as they were turned on. Also good to see they resolved the loose module issue, albeit kinda messily, but still resolved it.

[@GG-sj2wg]

Had one since they first came out. Love it.

[@HippocratesGarden]

I've got one of these on the shelf I've not yet installed, but think I need to. My intermediate setup is a full stack of 6 of the LL Batteries and an EG4 3k/48v all in one. I was trying to charge the battery from a 2k inverter/generator via the AC-IN on the all-in-one and wasn't getting more than 500-600W with zero loads. Could not find a setting that would bring it even to 1k. Seeing this can ramp the amps down, I'll hook it up and find a sweet spot to run the inverter/generator most efficiently and see how that does. Thanks.

[@bhbaker220]

So, if you don’t use an EG4 inverter in pass through mode, you can use a non-inverter generator to charge the batteries? There’s no clean up of the dirty power in the chargeverter, it just guarantees that dirty power does not go through the inverters to the loads?

[@hmtechsvc]

could you please consider making a video with more details on how battery activation works? nobody ever talks about that - but it seems all bms work that way (you have to activate it in some manner) - i'm just looking to understand how it all works - where did this method come from - idk - just very very grateful for your content and channel!

[@CurrentConnected]

Check out this video that we made, it could be what you're looking for: kzbin.info/www/bejne/invCfJ-tpZJ9r68

[@acinfla9615]

I got mine when they first came out and it has worked great. I can charge with a small generator or a large one without damaging the charge controller.

[@CurrentConnected]

They're pretty awesome!

[@icarus901]

Can't wait for the baker's dozen test. Thanks for doing a breakdown on these units!

[@CurrentConnected]

kzbin.info/www/bejne/hXmkiayagNmbjq8 Here ya go!

[@shaunnightfire8269]

Could you get the full 100a output with dual 120v generators using a parallel kit. Seems each module is just 120v and 240v is not actually needed for full power.

[@oswaldmosley6179]

My generator as a NEMA L5-30R 120v 30A output in Sine wave, do I need an adapter of some kind and if so what one?

[@goodcitizen4587]

$400, cool. Thanks for opening it up.

[@billykulim5202]

so basicaly it just 2 telecom 50a powersupply whic on parallel connection and add a module to control the output interface?, and those telecom powersupply you can get $50 each used???

[@peterking1134]

Can one power supply be connected to multiple batteries?

[@CurrentConnected]

Yes, for example if you have multiple batteries in parallel

[@rongray4118]

I am actually on the phone (on hold) with Signature Solar right now. I would like to know why this charger is limited to Lithium Battery Banks. I do not understand why it cannot be used for Glass Mat Based Battery System. Would you have any thoughts in regard to why? I am interested in hearing your thoughts. We have (2) 48 volt ABSOLYTE GX Battery Banks @ 2,000 Amp Hours Each and I don't think that this could ever over power the banks but I could be wrong. If it is charging parameters this could be compensated with the same manner of adjustment that is being done with your generator, correct? Or am I completely wrong in my thinking?

[@RussellHogan]

So can hook this directly to the top and bottom of my 25K SOK server rack battery bank?

[@CurrentConnected]

Yes, or if you have a bus bar that the rack hooks to, the charger can feed to that bus bar as well.

[@RussellHogan]

@@CurrentConnected Mahalo!!!

[@obd6HsN]

Can we please have these in Europe???

[@marek8928]

Can this Chargeverter be supplied by 120V 400Hz generator or 120-200V DC?

[@nicholasthon973]

Does this work with a Tesla Powerwall?

[@randallmarshall3603]

Too bad it's only good for 48v batteries. I would love a 36v version. I use the EG4 36v charger which gets the job done but slowly. And you mentioned 208v AC input which makes me think 3-phase but I don't see this mentioned in the manual. Did you mean 220v / 240v split phase?

[@CurrentConnected]

The output voltage can go down to 42v, so, if that's within the upper charge limit of your 36v batteries it can theoretically work. We tested running it on 208v (two lines of a 3 phase system) and it works just as well as at 240v!

[@uselesseater5916]

@@CurrentConnected 36v lead acid usually charges to 43v

[@andreaskoumides9599]

Will these work on a European grid, 230Vac 50Hz? I saw that the sticker on the psu you removed in the video is rated from 100-250V and 45-65Hz @ 8:42

[@CurrentConnected]

Yes it will.

[@andreaskoumides9599]

@@CurrentConnected Excellent, thank you.

[@Sylvan_dB]

The "silver boxes" look more like two server power supplies.

[@bill2292]

Nice video, great information, very educational! Am I correct that I can use this with 220 single phase?

[@CurrentConnected]

That’s correct. Also on 120v, no problem.

[@NukeFPV]

Would have been nice to see the output on an oscilloscope .... So we can see the DC ripple etc and confirm it is actually clean output. Without that..... we're just taking their word for it. But thanks for another great video on a new product ;)

[@gf3803]

Anybody know what gauge wire the unit uses on the DC side that connects to the battery?

[@CurrentConnected]

25 mm2 (which is around 4AWG)

[@gf3803]

thank you!

[@offgridmgtowhomestead2520]

My friend got this, and it failed within 2 days. And now they have been silent in getting back to them.

[@CurrentConnected]

Well, that's an advantage in buying through us! If you need support we are available to help.

[@BenBrand]

Through Signature Solar? I had to go through six units to get two working ones. And it took months through Signature Solar and their awful service. Right after that Current Connected started carrying them and I noticed that the two I finally got that were good were a second revision with changes that fixed some but not all of the issues. Hopefully that's why Current Connected stocked them later and Signature Solar was selling out of the original units that never should have left the prototyping bench.

[@HighTechLab]

@@BenBrand I just installed 12 for my parents on an 80kW generator. No problems on a single one. I’m posting a video on my channel tomorrow.

[@CRsolar]

Hey that video is gone . Did you have an issue... I like your testing this stuff for me. Be honest now.

[@RonKatz]

Nice, but no electrical approval. Not UL listed or CSA approved. Big issues with electrical safety.

[@UKsystems]

Actually most usual app approvals can’t happen of products with third-party approvals for other countries. The UL system just hates that so actually if something is approved it means it’s not actually safe in the majority of countries in the world exactly far safe to not have that approval.

[@LarryRichelli]

In the USA these cost $400 but in Asia they are $80.....makes one wonder what is going on!

[@otm646]

Where are you finding them for $80?

[@UKsystems]

Because the United States is overpriced and things are the best country so brands put the prices up

[@quickquote1568]

A 48 Volt output is not high enough to fully charge a 48 volt LFP battery. Even 57 volts is not high enough. The output should be at least 58.4 volts, or 3.65 volts per cell.

[@CurrentConnected]

This is a bulk charger - to replenish up to 90-95% of your battery from generator. Ideally, you would have solar / other charging methods to finish topping off your battery, instead of burning fuel.

[@quickquote1568]

@@CurrentConnected Then you should be advertising this unit as being only a bulk stage charger,. You would not be burning much fuel or generator run time topping off the final Volt and a half with a properly designed charger that offered a full charge.

[@HenkBronkhorst-c8c]

your not even talking about 20 % from users the other 80 % using simply single phase

[@JonOffgrid]

That nice but man it alot of $$$$

[@CurrentConnected]

Feel free to share what can do the same as this at a better price point. We will add it to our catalogue.

[@otm646]

There is nothing close on the market that can do voltage and current control while delivering 100 amps at 48v for $400.

[@GoodmanMIke59]

You were recommended highly by Will Prowse, but PLEASE ... at 0:44 Never EVER say "to the next level!" ... SOOOO "millennial!" 😂 Actually a little bit shy of using LFP batteries (SOOOO Boomer) because my grid tie, battery backup system is flooded lead acid, the last 12 years. I also operated a WW2 Victory Ship that could make turns without a candlepower of light ... So definitely geezer time. Off-grid cabin will have a 48 volt system charging to DC equipment, just enough solar to keep it floated. Likely AGM with this Chargeverter. Or not.... kzbin.info/www/bejne/gIDPkoStrpycb8Usi=qEIZrUNGshvPHsRR kzbin.info/www/bejne/iKGbeaamnpl1eZYsi=cZ2UUAOjnuzPHDe6 Build up from there ... Just comfort level for now. Possibly a hand truck system like Will Prowse built. THEN I'll use LiFePo4. Very good video.
