Getting a refund, can’t use my 48 vdc windmill with EG4 system.

This is odd.

There is no need to specify any specific device that would void warranty. Any failed device can cause voltage spikes and noise or whatever.

The specific cause would be voltage spike not "wind turbine" or "lightning" or "generac".

I wouldn't worry about it.

So, last week I ordered 2 EG4 6000XP inverters and 4 EG4 indoor batteries only to find out today, I would void my warranty if I were to include my 48 vdc Southwest Whisper 500 wind generator, into the mix. Also, my 48 vdc Kohler propane backup generator, also not approved to tie in. I had hoped to do a total replacement, but looks like I need to do better research. Anyone else have this issue?

If you are indeed returning all your EG4 stuff, you sound like a good customer for Midnite as a solar/wind friendly company

It's also possible something could fail inside the EG4 inverter, causing a rush of current from a connected device. It's not necessarily the connected device that causes the failure.

SMA used to support, but discontinued Windy Boy. You can get older model Sunny Boy through the 5000US series, which have such MPPT settings.

Yup. I think what they might be saying is they'll maybe cover a battery failure if the voltage spike is caused by the EG4 inverter but will not cover a batter fried by something 3rd party.

Make sense?

In other words your wind turbine company or generac will cover a failed wind turbine or generator but they won't cover the battery their failed equipment damaged.

Eg4 will cover a failed battery if damaged by their own equipment.

Or maybe I am putting a positive spin where it doesn't belong.

This is too cute. I would have to buy all 3 like a little girl collecting all of the different Barbie accessories. 🥰🥰🥰

This is blowing smoke up your butt. Now if you hook a DC source to your batteries and it is not designed for that and overvolts and blows something up, ... On you. I probably would not throw random 48v generating devices on the bus without confirming they will work, and or, I would have them pass-thru an MPPT device on the way.

I don’t know if the wind generator charge controller is MTTP or not, but one thing for sure, the wind generator doesn’t just go straight to the buss bar.

But if you buy a UL Listed ESS consisting of EG4 18kpv & PowerPro, I think the listing would be violated with any DC coupled sources or loads.

The BMS may log voltages and currents. If anything delivers spikes above what the FETs can withstand, they will be damaged.
"Windmill", does that have voltage regulation so it will not go over-voltage even if BMS disconnects? Some have a shunt regulator.
Windmills can also be fed through charge controller (Midnight Classic with Clipper) or inverter for AC coupling (Windy Boy, probably something like Clipper).

The Southwest Whisper 500 does have a charge controller and a power dump when 56vdc is detected.

You should see my storage shelves :giggle:

I also have Sunny Boy Storage, Sunny TriPower, Sunny Island Charger, Sunny Boy Control, Sunny WebBox.
Expect to get a Sunny Boy Smart Energy.

Hi David!

If you don't mind me asking, who was it specifically that told you this? We'd like to make sure they have the correct information. It doesn't void the unit to add this to your setup, but if it causes any damage to the unit, the warranty doesn't cover it.

You guys have been doing better recently. Credit for that.

Your statement above doesn’t make sense.

Put another way, it’s fine to do this. But if something goes wrong, it’s not.

That’s pretty bad bureaucratic doublespeak.

I’m a fan of plain English drafting. And I’ve spent many years working with engineers translating engineering speak to English.

Please define “open-loop lithium battery communications.”

Is a chargeverter UL approved/listed to connect to a 18kpv+power pro ess combo?

All sounds like nonsense to weasel out of warranty claims and we've seen that so many times before.
 
timselectric said:
Honestly, it sounds like a standard warranty.
If you connect 3rd party equipment to it, and that equipment damages it, it's not covered. (Assuming that it can be proven that the 3rd party equipment caused the damage)

With some companies I think the burden of proof there is on the poor end user that it didn't cause the damage ...
 
sunshine_eggo said:
Installation of alternate suitable charging sources does not violate ANY of the above.

Why is the OP being told he can't use wind or a DC generator, and it will void his warranty?
Click to expand...
I am being told my warranty would be void because the equipment I wish to 'tie in' hasn't been tested or approved by EG4 and therefore, should there be any issue and I have 'added equipment' hooked up, that's not approved, it will void my warranty.

Can't wait for the v2 chargeverter with closed loop to eg4 becoming mandatory to maintain warranty.....v1 trade in program...?
Click to expand...
It’s not even clear there’s going to be a firmware update to allow closed loop comms between EG4 batteries, ChargeVerter, and inverters simultaneously. 🤷‍♂️

And of course open-loop battery comms are by way of an analog signal.

Interesting........
 
Part of off grid is being able to use any available energy sources, hydro, wind and solar as long as it’s within the system’s working range in regards of voltage, current and quality. If system is so fragile that the manufacturer needs an easy out….I’m out. Next

That statement makes perfect sense to me. A third party device can be connected to an Eg4 but if the third party device causes damage to the EG4, that damage should not be warranted by EG4.
