Re: [RE-wrenches] Battery Monitor for Li

[Kirk Herander via RE-wrenches]

But Blue Planet does not have a native SOC / voltage monitor. Egauge and
Namaka, which I both have on several BI systems, do not correlate.
Supposedly they are coming out with a native monitor soon.

This has been an issue with me, these batteries all have a basic BMS and
then why does Simplify not support their own with a readable BMS, Fortress
has a monitor, Blue planet has a BMS.

Re: [RE-wrenches] Battery Monitor for Li

[Chris Sparadeo via RE-wrenches]

Hi Matt,

I typically like to keep battery monitors consistent with inverter
manufacturers. Outback and Schneider Electric and Magnum offer good native
battery monitors that, when tuned in correctly, work well with LFP.

That being said, I have definitely used the Victron BMV 712 paired with
SimpliPhi and hand full of times with great results. It’s a shunt based
monitor with easy installation and Bluetooth connectivity. Accuracy is
nowhere near closed loop, however if programmed correctly, it’s a helpful
addition.

I do wish that SimpliPhi would develop a plug in BMS display for their
AmpliPHI series, similar to the Discover AES Link. This is where the
Fortress eVault really gets it right.

Kindly,

Chris

Re: [RE-wrenches] Battery Monitor for Li

[Ray Walters via RE-wrenches]

Default efficiency on the TriMet was 94%, needs to be quite a bit higher 
for Li+.  I'd try 98%.


2nd point:  Customers have always obsessed about meter readings: they 
need to take a chill pill, and accept its not going to be better than 
+/- 10% accuracy.  Or get a Fortress battery with built in SOC readings 
on the unit.

Re: [RE-wrenches] Battery Monitor for Li

[Sindelar Solar via RE-wrenches]

Matt, you didn't indicate whether this is a TM2020 or a newer TM-2030. 
The steps are the same, so it shouldn't matter.
Set the charge efficiency to 99%. Set the voltage to a few tenths of a 
volt below the Simpliphi's BMS setpoint.

Set the amps to off.
Make sure that P01 for auto reset is on.
Should work fine.
Allan

I’ve never installed simplify batteries. Do they make their own state of

The trimetric has a perimeter called charge efficiency % You can tweak that

Also the trimetric should be reset to full on a regular basis, When you

[RE-wrenches] Battery Monitor for Li

[Matt Sherald via RE-wrenches]

Hello Friends,

I have an off-grid customer for whom I recently installed some SimpliPhi
3.8kW batteries.  This is an older system and it has a Trimetric battery
monitor that the homeowners have used for years to keep an eye on their
battery bank.

The SimpliPhi batteries appear to be working fine at the site, but the
homeowners feel uneasy b/c the Trimetric is reporting that they are
finishing each charging cycle with an amp-hour deficit.  The voltage of the
SimpliPhi batteries indicate that they are getting fully charged and are
doing so fairly early in the AM (solar is the primary power source).

I've spoken with SimpliPhi tech folks and their hunch is that the Trimetric
is not reporting correctly.  They suggested that a Victron BMV-712 would be
more accurate at tracking Percent Full etc...

Do you folks think that the Victron is better at counting Ah in/out for Li
batteries?  Or is the Trimetric adequate - do I maybe just need to adjust
the settings?

Anyway, the implication that the Victron BMV was better at monitoring Li
batteries has me curious and I will enjoy hearing what the group thinks.

Thanks for your time!

-Matt
