Re: [RE-wrenches] Fortress

[William Miller via RE-wrenches]

Jay:



Here is a link

to the study.



The web page needs to be updated with this information:



There are two settings to be changed in the Sunny Boy Inverters:  Backup
mode and Default.  See Below:





I had set the default to OFF_Grid but I had not set the Backup Mode to On
All.  It was in Off.



There is a possibility changing the Backup Mode setting may fix the
Frequency Shift Power Control problem that is the root of this dilemma.
There have not been enough sunny days to see the PV bring SOC up to the
level of near 100% where the problem exhibits.  As soon as the weather gets
sunnier and the days get longer I will see what happens and report back.

Good morning my fellow wrenchers. While I see the comments on SunPower and
the challenges, are any of you having similar issues with Fortress? Their
bms boards from the early classics have not held up and even after
replacement there are still issues ( parallel batteries and stand alone not
showing accurate #’s,  ). While support has been, well supportive, the
issues persist. Any thoughts or fixes you have come up with?? I just had a
customer unplug the coms cable from their sol-ark and bring their readings
to volts VS %% and it is starting to work a bit better. Any and all help or
ideas appreciated.

Yes, the site I mentioned is only for the fortress envy inverter.

I’ve had the same weather as you, being in northern Vermont, that is where
that system crashed that I mentioned in the previous email, definitely did
not reach a full state of charge in January.

 The national weather service reported it was the cloudiest January since
1951.

Re: [RE-wrenches] Fortress

[Dave Tedeyan via RE-wrenches]

Kirk,

That site looks specifically for the Envy inverters. Do you know if the
Guardian site is working? My credentials will not get me in at this time.
www.app.fortresspower.io

My sites have no comms between the batteries and the inverter, since it is
an Outback system.

And yes, there is certainly an issue with SOC drift over time without
getting a full charge. I was told by Fortress tech support that the eFlex
batteries needed to get over 55V to calibrate the SOC. Yet, in their
settings, the generator is only supposed to bring them to 54.4V. The solar
will bring it higher. But this was a problem here in upstate NY, where we
did not have a sunny enough day in the entire month of January.

Cheers,
Dave

Re: [RE-wrenches] Fortress

[Dave Angelini Offgrid Solar via RE-wrenches]

So this is all open loop with outback correct?  I can't even get into 
Simplyphi. website today. Maybe the windows update...


The battery below was suppose to be networkable but it looks like not 
much progress.


* Model: AmpliPHI 3.8kWh
 	* Inverter compatibility: Sol-Ark, SMA (coming soon), Schneider 
Electric (coming soon)


 A question, it looks like Outback is not closed loop with any battery 
company. I hope I am wrong!

Re: [RE-wrenches] Fortress

[Dave Tedeyan via RE-wrenches]

I also have been having some issues with reported SOC through the Guardian
with Fortress. Fortress is generally responsive, although no one has
specifically addressed my concern yet. What I have seen with two recent
eFlex installations (replacing an existing battery bank on an off-grid
system) is that the reported SOC in the Guardian app for some batteries is
way lower than it should be. For example, one system is at 92%, 92%, 92%,
62%. Yet the lights on the batteries all indicate that they are in the
75-100% range. The other system is reporting 23%, 63%, 62%, 25%, 48%, and
again, all the LED's on the batteries are in sync. This has led one
customer to keep disconnecting the batteries and trying to charge just one
of them up and then fiddling with it until they are all back within a good
voltage range, when I am nearly certain that they are all the same voltage
even though they are reporting different SOC on the Guardian app only.

I am looking forward to when they have the website up and I can look at
historical data to see whether this battery is actually doing more work. I
suspect it is not, but then maybe I can get Fortress to look more closely
at it. And for all these batteries, the cables are exactly the same length
and going to a bus bar.

Has anyone else noticed this discrepancy between the guardian app and (what
I think is) reality with the SOC?

Cheers,
Dave
