😮 12x EG4 Chargerverter 5000's - 48v 1200A Battery Charging System!

[@HighTechLab]

To answer questions in advance, no, they are not growing crops with all the power. On the property, there are 3 RV's, one for my mom, one for my dad, and one for my step-dad. RV's are not very energy efficient...so in summer when it's 110F outside, they use a LOT of power to air condition them. The electrical room is also air conditioned and there is a hot tub that used to have the excess diverted to it, but sometimes they don't like waiting until there (isn't) excess. They only have about 12kW of solar, mounted flat, so it doesn't get anywhere near peak production.

[@guytech7310]

WOW! Quite the project! My only recommendation would be to have kept the Plugs to make it easier if you need to replace one of the chargers in the future. Sooner or later one them will break :( But I can also see why you probably didn't want to go through the hassle & cost of wiring all the outlets.

[@USA-GreedyMenOfNoIntegrity]

[@randacnam7321]

Sounds like a good PV mounting structure would be a solar canopy to park the RVs under so sun isn't hitting them directly which would cut the heat gain.

[@davefroman4700]

Gov Subsidy WILL cover 30% of the cost of such a structure if you are covering it with solar now.

[@Evolution56]

That's an insane amount of chargers. EV's have chargers one 10th that size that can take anywhere from 50 to 350 kW. I wonder if one could be gotten to do the same job, but probably would need to be actively cooled. Anyway, very impressive setup. Good job. Edit: Opps! Those EV chargers are DC to DC! Yours is AC to DC. Max AC to DC in EV's is 19.2 kW that I know of and they are expensive.

[@spiralout112]

Also EV chargers are generally liquid cooled.

[@Sylvan_dB]

The amps are also a problem. 50kw into a 50v battery is 1000 amps. 50kw into a 500v battery is only 100 amps. Less amps, smaller wires, less heat.

[@whattheschmidt]

@@Sylvan_dB I bet within 10 years almost all EVs will be 800-1000V too even.

[@mgkleym]

They really don't. The level 1 and 2 chargers are actually just a fancy box with a relay in it the actual charger is built into the car and usually only around 5 to 10kw max. The dc fast chargers that can do 50 to 350kw are entire racks of equipment somewhere off to the side of the "charger" you plug your car into.

[@nooneswedish5142]

Finlay !! I can not understand why this is not the standard. to be honest the Inverter Charger combo is only god for RVs that frequent trailer parks. In any other setup you are better of separating the Inverter and Charger , and definitely having a charger that can tolerate "dirty AC".

[@norsk54472]

I AGREE. It is was smart to timeslice the inverter/charger.....back in the day. But Today with cheap CVs, separate chargers makes more sense and provides simpler operation, saving the vital inverter for inverting I have a XW Pro and have switched to this model. ONLY use the inverter for loads, and not the internal charger to power charge battery (It is hooked up for possible emergency use) I have 2 CVs with 2 L14-30r from 2 grid circuits and 2 L14-30r from the 2 generator circuits. When solar input is low I can use either grid or generator to boost power. Save stress on the internal charger AND can have spare CVs at a cheaper price. LOVE this architecture model

[@ejennings98]

Solar panels are cheaper compared to batteries, but the generator is an awesome backup. I would love to see a video in the future of the system upgraded with lots of solar.

[@Sylvan_dB]

I guess some people do not hear smoke detectors chirping...

[@HighTechLab]

Lol…I tried changing the battery while I was there and it was still chirping. Time for a new one

[@usmcp]

Nip that code black in the bud 😂

[@flinch622]

It would be helpful to have a reactive load gauge [kvars] on that generator. PWM or SCR systems tend to have lousy power factors. That inverter disconnect seems odd on account of voltage is stable - you'd think it ought to be happy. But... does 240 from generator match inverter design? Spec sheet suggests 175-425v input, so that sounds fine. I have had charging systems in the past where they were sligtly under-specd for battery bank Ah capacity - they stood up fine, until battery age started demanding more current, and the charger failed from the mismatch -upgraded to a higher output charging unit and problem solved. So this was a video to watch: maybe battery overtemp and/or overcurrent was my first instinct regarding shutdowns. As for the newer bigger generator... what AIC is required? I was thinking main has to be 120,000? This is a fairly big project as details go. Throw some dessicant packs in that generator control panel to keep electronics happy over time - any cabinet outdoors has a way of breathing with heat/cool cycles day & night that can cause something approaching a mini rain forest inside. You might [might] need to pull back on charging volts to 54v?

[@retrozmachine1189]

Aye to this. I have no experience with these battery chargers, and in all probability never will, but it wouldn't surprise me at all if they have no PFC at all. I'd be happy to be proven wrong and find there is at a minimum passive but active would be preferable.

[@AintBigAintClever]

There's another possible option, which I saw in an LED emergency lighting unit designed for outdoor use. A little rubber bladder inside the panel, connected through to the outside. Pressure inside the cab drops, bladder gets bigger. Pressure rises, bladder shrinks. The one in the lighting unit was like a little rubber light bulb. For a bigger cab even something like a party balloon on a hose connector might do the trick. Video nel567DBAQc at 1:37 shows the one I encountered.

Not too bad, especially when compared to that monster generator. The fans are at full speed at 85A, but I honestly expected worse when I was installing them. The room doesn't really have much echo, so when you stand back 10ft it's not bad at all.

[@keithcress1335]

Little confused; I thought you said it was a 480V generator. That would be phase to phase. How are you running 120/240V chargers off that? 277V to neutral would still be too much voltage. What did I miss? Also, are those chargers all completely Isolated so they don't care how their outputs are paired? Thanks. Lastly; You're not over "C"ing those batteries charging them back up almost all the way in only two hours? What's the allowed charging C rate?

Now that’s an amazing way to harness all the power. I really like the serial hybrid approach. Great video!

[@felaxchow207]

One nice thing about those switching rectifiers is that it really don't care about the line frequency as much so long it is within 50 to 60 Hz. You're definitely getting the most out the generator by using it in 3 phase mode. Even if you lose a few chargeverters, definitely have enough redundancy to keep things going until you get them replaced. Maybe EG4 might come out with a budget rack mounted version for higher power configurations?🤞 It be one heck of a setup and much cleaner for larger installations...

[@zaprodk]

I believe they would run off of straight DC. There is nothing inside that uses the frequency for anything. You just have to make sure the rectifier can handle the current if it's running half the diodes at 100% duty cycle.

[@Deveak]

Wish they would make a 24 volt version. I did find some cheap telecom rectifiers, pretty sure it’s the same as the EG4, just without the additional programming and charging functions. I plan on hooking up an mppt for proper stages charging. Downside is they are single phase 240 volt and at 120 volts they sedate to 2000 watts.

[@randacnam7321]

They would run off a wider frequency range than just 50cy to 60cy. 83⅓cy, 91⅔cy and 100cy railroad signal power would be no problem, nor would 40cy or 70cy (ancient AC standard frequencies). Only things that may be a problem are things waaaayyyyy outside of the normal utility frequency range like 25cy railroad traction power (insufficient bulk capacitance on the switcher primary buss) or 400cy aviation power (input diode switching speed, AC input shunt capacitor current and AC input circuit breakers; 400cy arcing is a right pig to interrupt).

[@offgridwanabe]

Gazooks man what town are you supplying.

[@kevinhoober1863]

Looks like you have your phases well balanced...but that neutral is technically undersized. I would be interested to see what kind of current that neutral cable sees with the load of chargeverters, and if their loading stays balanced as the battery voltage comes up. Another scenerio where the neutral could see more current is if a few chargerters went off line...and happened to be on the same phase--seems unlikely, but still worth considering. Another option would be to forgo the neutral all together and run as a 208 delta (of course this would mean double pole breakers for the chargeverters). Love this content!

[@HighTechLab]

Neutral has 0 amps. The chargers are connected phase to phase. They don’t even have a neutral conductor. I only installed a conductor in case I need it in the future for ancillary items such as phase loss detection in my PLC

[@kevinhoober1863]

@@HighTechLab I went back and looked--can't believe I missed it the first time!

That is a beast of a setup! I'm curious how the Chargeverters are holding up now that it's been a few months. We are building a stronger charging solution for our off grid cell tower site. Have the Chargerverters kept their voltage and amp settings through all of the various generator cycles? Our generator is tiny in comparison (9500w). We have 2 Chargeverters along with the Victron Quattro 5000 charging which will be disabled most of the time in order to keep the generator 240v phases even. Plan is to back off the CV amps to keep the generator around it's peak 24x7 output rating. Generator only runs if there's multiple cloudy days. It's a very remote site so if the CVs settings get lost, they will overpower the generator if they go back to 100A.

[@AintBigAintClever]

Given that you've got a finely-tunable load right there you could maybe perform some interesting tests on the generator to find the sweet spot where it's at its most efficient, not just for science but for practicality as you can hopefully save fuel. Fill the tank right to the brim, run for an hour at xx kVA load, measure how much it takes to brim the tank again. Repeat at different kVA loadings, either by adjusting settings or turning off balanced triplets of inverters. Graph and learn :) Worth running a three-phase socket off that panel as well? You've got a three phase diesel-powered supply available for the odd occasions when one would come in handy.

I think it might have been worthwhile to install the twistlocks off the breaker panel, and you should keep the DC wiring original/full length. The reason? Think about maintainance/warranty… It’s much easier to remove a plug, and send back a defective charger under warranty, to EG4 if it hasn’t been modified, also faster for you, as you won’t have to open the panel and loosen the screws on the 2 pole breaker.

Some equipment is just better at handling the floating neutral that most generators are setup for.
