New EG4 Chargeverter V2

I'm sure v2 is probably better with various added features. But some aren't useful for everyone. Auto gen start or comms wouldn't help me any, though a gradual power ramp up would. A swappable cord is great, but I don't mind just rewiring.

The big question is is all 12 V1 chargeverters still working on @HighTechLab 's family property :)

All of them are online. I had to wire in the 1200cfm exhaust fan to turn on when gen is running 😁

Refer to the lower scale:

I had to add another digit to our battery amperage readout:

when I got the 12th charger online, I found a very strange issue in the SOC calculation, I found out I was at the end of a 16 bit signed register in the PLC

the power ramp up on GC version is quite slow, I didn't time it but from what I recall it was at least a minute, possibly two.

Thank you! I really wish that one day we aren't stuck with a landlord at our warehouse that won't let us put things on the roof. Then the fun would really begin! Man, a megawatt of solar sounds like fun.

Keep growing, build your own warehouse. Make it an example of all things "Current Connected". Many of us here directly support what you're doing.

Nice. V1 does not have a ramp-up correct? I think I recall some people noting that it would stall out their gen by near instantly trying to pull full power?
They really should advertise V2 (GC) has ramp-up if V1 did not.
 
Does anyone know if I can hook a chargeverter up to the Smart Load output of a Sol-ark or EG4 18kPV to charge a remote battery bank(seems like this should work fine)?
Basically I want to charge a large bank in another location when I have excess solar available.

Will the chargerverter just turn on and start charging when the smart load output turns on?

Is the chargeverter powered by the batteries when the AC is off?

Does the chargeverter remember V and I setpoints if battery and AC are both off and then turned on again?

Yes, yes, yes, and yes.

V1 did ramp up, but not as gradually or smooth.
 
Dexter, so I missed part of your generator/chargeverter story. You have 12 chargeverters connected to a large generator?
I have a 55 KW generator, natural gas powered, continuous rating, and I have thought about attaching a number of chargeverter type devices to it. But my battery bank would need to be a lot bigger in order to absorb that much power. Of course the generator doesnt need to be loaded to 100%.
 
Yeah, my parents have 164kWh of battery bank to dump into. Thanks @OpenNRG for being a ninja on the link!

It's rather funny that the GC (stands for generator control) functionality was added due to feedback from this forum and now that EG4 developed and added it, people are upset that it made the product a bit more expensive.

That said, I think some of the differences with the new chargeverter is poorly noted and make the higher price a fair representation of the value added.

The new chargeverter has a removable input cord, so swapping from 120v plug to 240v plug is very easy. The output is now Dexgon (similar to amphenol) connectors so the output cords can be easily unplugged - and shops like mine will soon be able to offer custom cables could provide you whichever length and ring terminal config you like - or give you options if you need to move the chargeverter between systems. The screen is way better too, overall efficiency is significantly increased meaning less energy wasted as heat.

Dexter....did you guys order a bunch of the DEGSON connectors in various configurations? You cannot get them in the states as far as I can tell and I don't think they are compatible with Amphenol connectors. https://www.degson.com/product/productlist20_4438066.html?lang=en

Are they different than these? https://www.digikey.com/en/products...ZX4AnAJYA7AOYgAvvMIsyIgK5iAMkQDWAAgAKmNdm7ygA

They sure look like they should be compatible. but guess someone would have to verify.
 
While I am somewhat interested in the communications capability of the new ChargeVerter, it sounds like they haven’t actually implemented any of the obvious integrations, nor is it clear that they ever will.

However, the price delta is reasonable, and you can’t get the old ones, so I have two of the newer ones on order, and I guess I can hope that they will allow integration with their 18Kpv and power pro batteries sometime in the near future.

I mean, I could query solar assistant for the battery SOC and then talk directly to the ChargeVerter with another RS485 or CAN interface, but that’s another Raspberry Pi and a bunch of when when (in an ideal world) that should all just happen automatically and seamlessly. Here’s hoping!
