It's not for a generator input. It's an Output port that provides power to a load usually designated as essential/critical that requires power during a grid/mains outage.
When grid fails and the inverter is battery and PV powered, loads connected to the AC-BACKUP are still powered using either...
The output on the AC Backup operates in bypass essentially when grid is available. EPS is activated on grid failure and of course a battery connection.
As long as the grid is up though the essential loads are getting power from Mains.
The red circle is a transfer switch to power those critical...
Victron BMV 700 (3.3v so no resistors needed)
Solis RHI-5K-48es (not the 5G)
Unknown BMS but I suspect it's a brand called SMARTBMS. I have a rebranded 50ah but did some digging and seems a rebrand from Leoch.
Waiting for the arrival of a replacement 200ah which has a JBD BMS - convinced it will...
I just used the DuPont jumpers - it fit relatively snug but threw on a few drops of hot glue to make sure anyway.
Also, if anyone is wondering if the solution would work with a Victron BMV as opposed to the smart shunt standalone- it does. I'm also not sure what BMS my rack battery has in it...
Got a Pi3 - running just fine. Thanks again @shavermcspud . Great work.
For anybody that might be tempted to try and get both the Wifi Stick and this solution wired in together and working in tandem - it doesn't. Well my efforts has been in vain trying to get it working with the Solis S3 Wifi...
Hello @sijones2010 .
Really appreciate the work you've done on this. I'm about to purchase a Victron BMV 712 to get your solution implemented with my 'unsupported' battery. Before i take the leap, was wondering if you've implemented any further fixes that you mentioned in the previous post?
@sijones2010 - on any of your implementations have you perhaps experience SOC drift in terms of what the BMS is reporting being different to what the shunt reports and in turn the inverter?
I started off with all reporting 100% SOC and over the past few days it's drifted insanely where the BMS...
Hello all, hoping for some help on an issue I'm having on a RHI-5K-48ES. On loss of grid, the EPS/Backup output is activated but immediately throws out an 'AC Overcurrent' alarm and disables output on the Backup output. A few minutes later it automatically resets itself and then clears the alarm...
I downloaded the Solis version. Nodered does indeed show data and actually all appears to look just fine in that space. By getting Grafana,Influx,MQTT up I just thought it would magically work despite having a sense it wouldn't because of the Pi zero and hiw different it is to the other Pi's
I have the same Inverter and also faced the same challenge when initially commissioned as at the time I had a bank of functional Lead Acids with the intention of riding them out before moving to LifePo4. The sticker on the side of the inverter explicitly states under the Battery info that it is...
Happened upon this,
apt-get install grafana-rpi
Don't recall the list or source, ran a wget for it from somewhere. Like you said though, likely not a supported version
After purging the version on the image and running the above, that got Grafana up and running just fine on the Pi Zero.
Not entirely true. Our incompetent government is thinking about charging solar users, not yet implemented. As you say though - TIA - This is Africa - so good luck with the clowns ruining the country trying to get that monthly fee from solar users.
It simply won't happen law or no law.
And yes -...
That was my thought exactly. I can only think it's perhaps locked for specific markets perhaps (?) I'm based in South Africa and the local Solis support channel is beyond useless to the point of being pointless it seems.
My Model number reports as F8 and my software version reports as 250012...
Hello @shavermcspud
Hoping you can shed some light on my challenges getting this running on my side.
I flashed the image file, but on boot Grafana, InfluxDB and MQTT does not startup. There's likely more not working that I've yet to discover.
I purged Grafana, InfluxDB and MQTT and...
Something definitely looks wrong. It's all a bit convoluted for me to pinpoint exactly what looks wrong though
Did you perhaps already flip the switch on it all? Any smoke, explosions or fire? :LOL:
I thought setting to "User Defined" doesn't work as it still comes up with CAN failure as opposed to "Can Null".
It does so on my side and I had to use the "Lead Acid" option.
Perhaps firmware related?
Yes. Absolutely positive the connections are right.
I suspect grafana, influx and mosquitto were all broken after flashing because your image is likely meant for something that's not a Pi Zero perhaps?
I've got grafana, influx and mosquitto all running just fine now though. Double, triple...
Your idea of moving your lighting and some essentials circuits from your main CU to an essentials CU fed from the AC Backup port is a good one and is exactly the purpose of the AC Backup output. Mine is wired that way with a changeover switch though. In the event of an inverter failure I can...
Not good at all. A sad sad state our country is currently in. 15 years of what we call 'loadshedding' which is a direct result of government corruption. Oh well, can't possibly get any worse. Oh wait...I'm sure it will ?
Been waiting in anticipation for Solis support. Have used Solar Assistant in the past on an Axpert inverter many moons back. It definitely added value and enhanced functionality.
Is this loss of power your actual experience? I ask because that shouldn't be the case. There shouldn't be a loss of power. In the countless occurrences of loss of grid just this year where I stay, my Solis just transfers seamlessly with no loss of power.
I have both connected and running at the same time. Works perfectly and stats are logged to both platform.
In order for me to get the ShineWifi Dongle inserted in to the USB Port alongside the USB cable connected to the port right next to it running to my Pi, I had to remove the ShineWifi dongle...
Really hoping somebody can help me with an issue.
Have a Solis RHI-5K-48es (4G) that is missing the Lead Acid battery type. It's a new purchase and I assumed it would have working User Defined settings to work with an already owned 'unsupported' LifePo4 rack mount battery I have which does not...
Another weird anomaly - I've never heard the fans on my RHI come on - not ever. Under max load or not. Wonder if they're all created equal ?
But i do have an external fan mod - so maybe that's preventing the internal from kicking in due to temps. don't know.
