why is my MPPT not charging?

So its not a system I installed, but one we had installed.

Our setup includes:
4x 210Watt solar panels
multiplus 12/3000smartsolar Mppt 100/50Cerbo GX
500A Smartshunt
Smartdongle
MK3-USB
GX50
4x 100Ah LiFePo4 batteries

So as I understand how it was installed, the Lithium batteries are supposed to be charged by the solar panels, and then they in turn charge the battery that came with my trailer (which is a lead acid). I had to do the programing to get it finalized, I followed the battery manufacturers specifications.

Our system worked for a while back in April, then it stopped out of the blue. Since then, I have pulled down all my panels to test diodes, all came back good. Followed the wires and checked all inline fuses, good. Checked all breakers, good, all wiring and connections labeled correctly and checked. Reset all components to factory settings, let sit for a bit and reprogrammed for my set up. Ran my batteries down to low 12v (12.2v), and nothing still. My displays and info all just say 0-1watts, 0amps and around 22-23volts coming in from my solar and stays in bulk. I am at my wits end right now.

I have gone through so many forum posts and have tried everything on here, as well as various other forums and videos. Below are some screenshots I've taken this morning. Please if you need any more information to hopefully get this resolved please let me know and I'll get what ever I can back here for the community to look at. We are currently on shore power as well to charge the batteries back up, so if anything needs to be done off shore power let me know as well. Thank you all!


*edit* forgot to include my settings


**edit 2: I noticed recently that my ssc battery voltage and my multiplus battery levels are reading differently, 13.5v and 14.3v respectively. Is this an issue as well? If so how do I fix this!

Integrating Windenergy to a Victron installation

Hi,

I've been looking to integrate a SWT (small wind turbine) to my Victron Quattro installation and have some questions.

Is there a supported partner for integrating wind into a victron system? In my research i've found that the Bornay windturbines seams to be a good choice. Any one here that has some experiences with these units? What is possible to integrate to VRM for example?

It would be awesome if one could monitor the information from the windturbine on VRM.

What woud be best, AC-coupled (on AC-out) or on the other side (AC-in with a smart meter)?


If you (who are reading this) has allready integrated wind to a victron setup, could you please share your experience and setup?

Kind regards

SmartSolar 100/20 Bluetooth

When I go to the victron app (android samsung) the controller is listed, when I attempt to connect it goes to 20% and then cannot connect.

I have disconnected the controller overnight, done a fresh install of the app and a factory data reset on the phone, none of which worked.

Error 67 - BMS Connection Lost on Smart Solar 150/100-Tr VE.Can

I have a Smart Solar 150/100-Tr VE.Can connected by VE.Can to a MG Energy Master LV (With 2 x 200Ah HE batteries) and a Color Control GX. There is also a Multiplus 24/3000/70-16 connected by VE.Bus on the same system.


I'm having an occasional 'Error 67 - BMS connection lost' from the Smart Solar but I have unfortunately been unable to pinpoint what exactly is causing the issue. It never happens when the solar is isolated but randomly when solar is generating. It does not automatically recover unless I clear the issue by isolating our solar panels and reconnecting. Is this a known issue with Smart Solar VE.Can variants? Details are below. Many thanks!

What settings for 2x Sterling 140ah AGM deep cycle?

Hello,

I have 60A Victron MPPT SmartSolar 150--60, connected to 2x Sterling 140ah AGM deep cycle batteries connected in parallel.

What settings should I put into the charge controller?

There is information in this data sheet, but nothing clear to a beginner:

https://www.bimblesolar.com/docs/140ah-sterling-battery-datasheet-HP140-12.pdf

I have got it operating using the preset "Rotary Switch Position 2", which was what the charge controller had as default perhaps, but I have no idea if that is appropriate. Worried I am harming the batteries.

Thanks for any help.

VictronConnect Does NOT See Solar MPPT 100/50

We have a new Bruder Expedition with a Victron Solar system installed. A couple of weeks ago our system completely shut down. We were able to get it back online but now the MPPT 100/50 does not show in VictronConnect. We've followed ALL of the instructions. Have unintalled the app several times, unpaired from bluetooth and connected from within the app as instructed BUT the MPPT 100/50 still will not show. Just the BMV-712 Smart. The MPTT 100/50 showed up in Victron Connect before the system shut down. We have even turned the system off manually and restarted it several times. We have tried running VictronConnect on an iPhone instead of the Samsung tablet (Galaxy Tab Active Pro, model SM-T547U) and no luck. Really at our wits end. We are not tech illiterate but this one is stumping us.

2x 100/20-48v mppt for 4 panels or 1x 150/35

I'm dipping my toe into the victron world... I have roof space for 4 solar panels. I'm thinking 4xLongi 375W with open voltages of 41.1v. I was planning on using 2x 100/20-48v smart solar MPPT's and having 2 mini arrays of 2 panels. The roof gets good sun, but there is a tree which will partially block one panel later in the day.

Am I better with a single 150/35 mppt and wiring the panels up differently or even just having 3 panels in series not bothering with 4th?

My thinking might need correcting...

I weighing up whether 3 panels in series with an open circuit of 120ish volts will operate the charger longer for a 48v system than 2x2 panels with a max open circuit of 82v...

Also, by separating the panels on separate MPPT's and strings do I protect against the panel which gets shaded from dragging down all 4 panels if compared to them being on the same string/MPPT.

cost wise there doesn't seem to much in it.. Or is there a better setup entirely.


The system will be feeding...

Multiplus ii 3000VA 48v

2.4kw 48v plyontech battery (intention is to add more at later date)

Cerbo GX


It will be grid tied.

Really would appreciate some guidance

Many thanks.

BMV & SmartSolar Streetlight to warm battery box

Hi, I have a 190ah LFP battery going in to an ammo can which will be in my truck bed. I'd like to heat the box using small ~25w heat strip(s) when the battery is too cold to charge, but only if it was going to charge in the first place.

What I mean by that, is that if it's the middle of the night and below freezing, don't bother because there's no sun to charge with anyway. Similarly, if I have a foot of snow on the panels and it's freezing outside, don't bother because the panels might not even produce enough voltage to initiate a charge cycle.

I was thinking some combination of the street light function, load ouput, and BMV low temperature relay setting could accomplish this. Likely easily with the ability to invert the streetlight functionality but I do not think that's possible from my research. Maybe some NC relay that the streetlight triggers when it'd normally be operating an actual streetlight (night?)

Any ideas appreciated!

Low temperature cutoff not working

I have attached a temperature sensing cable to my BMV712 and it is reading the temperature off the battery. I have connected my mppt 100/30 through networking to the bmv and the controller is receiving the temperature. The controller is set to rotary switch 7 for my LifePo batteries and the low temperature cut-off is greyed disabled but showing 5c as the documentation says. However it is NOT stopping charging as I have tested this down to 3c. This is a VERY important feature for me as I live in the mountains of Colorado and we get cold. It is NOT working. Please advise.

Load output - Enable only when charging

I'm going to be putting a spare 75/15 MPPT charge controller in a small pelican case with some small circular vents. I'll extend the PV input and battery connections to be panel mount jacks on the outside of the box, so that I can charge up two portable battery packs (separately, of course).

I'd like to run a tiny DC fan in the pelican case to draw air through the vents, and I really only need this to occur when charging is occurring. The fan will draw extremely low power but I still don't want it to operate continuously in case I forget to unplug things when night rolls around. I'd prefer this to some temperature controller... is it possible? Not sure basic load output nor streetlight function would give me the ability.

Thanks!

Parallel 2 identical MPPT 100/20 and solar panels systems to a single battery bank

Hi. I have a 4WD vehicle that while travelling has a limited available roof space because of wind drag. So I wish to mount 2 x 130w panels in series facing upwards with a 100/20 blue tooth controller (SCC110020060R), which in most cases provide required charging of the battery bank, I used the Victron Calculator to confirm controller size. I wish to mount a sliding identical system below on rollers so that when the vehicle is stationary and possible partly shaded to the sun the lower system can be rolled forward to increase the charge to the battery bank when required.

Some possible extra information that may be useful;

1. I like to have some redundancy IE the completely independent system should panels or controller fail whilst working remotely.

2. The battery load is not connected to the load terminals of the controllers but via a separate low voltage disconnect device.

3. The controllers may need to be fan cooled because of the possible ambient temperature within the 4WD in the summer time 50C +. This can achieved simply by mounting the controllers to a common aluminum plate with a bi-metal plate type switch and fans

Questions

1. Will the 2 SCC110020060R synchronize / work together to charge the single 12v battery bank?

2. Do I need to change the controllers to a single 150/35 (SCC115035210) as the calculator suggested for 2 x 2 x 130w panel system.

3. Can I have battery bank temperature sensor on the controllers? Comment 3 above.

Thank you in advance for your advice

Victron 100/50 + Inverter Wiring Setup Help?

Hey guys, this is the very simple setup I intend to run in the coming weeks - can you please help me with the following:

[image]

1. Should I have a circuit breaker (as depicted)? And/or, any other protective devices in the diagram - and if so, what type/rating?

2. The system will be contained within a car for 85% of the time, I assume I should Ground the Inverter and MPPT to the vehicle (wherever I can find good contact). Though, the other 15%, it will be completely standalone at a campsite without being grounded...which I assume is the case for many setups?

3. The Panels come with some 12 Gauge, I assume that's fine to run there on? 4. ...anything wrong with the setup, improvements, suggestions?

Many thanks in advance - I really appreciate it (particularly @seb71 for getting me on the path :) ).

Set generator as running when AC1 is active.

Hi folks,

I have AC1 set as generator input and it works as expected, bar for a limit addressed on another post.

I would like to track generator run hours but I do not have auto start set up yet as this involves a modification of the generator.

I currently start and stop the gen manually, which works for me right now, and would like AC1 to set the generator start and stop flag which would then log run hours for me.

I apriciate that its litterally the reverse of what would typically be required.

Is this possible? If not is there any way to build and run a script to make it possible? Could I build a custom helper of example. or is there perhaps a helper that runs script?

Power Difference between values shown by Smartsolar and Smartshunt (Battery Monitor)

There are huge differences between the Values I get from the MPPT and the battery. Everything is luke warm to ambient temperature. Cables are not an issue - they are total overkill.
The Smartshunt values are independently verified by a very good BMS.


Anyone can shed some light on the situation for me?

Power Solarpanels: 34.07V * 13.4A = 456W

Power Battery: 27.27V * 16.30A = 445W

MPPT efficiency loss: 2.4% That's ok

[image]

Meanwhile, the Smartshunt shows verified 407W!!

Where are the missing 38Watts??

[image]

I am using LiFePo4 at low C rates - so round trip efficiency is virtually negligible in light of the losses I am trying to figure out.



Update: I've measured everything, thank god that I've the equipment for that since values vary in the milliseconds.

The only thing that does not match at all is the purported Solarpanel amperage output. Voltage seems pretty accurate. As such 1.4A were reported, when there were really 1.1A. A 21% difference!

That makes me really fed up and unless that is my specific unit I am gonna make sure that other people will become aware of the kind of product they are really buying.

But that doesn't explain everything. The only thing certain is that there are no real physical losses present.

Help with simple Off-Grid Setup 48v EasySolar + LiFePo4

Hello,

i'm starting my plans about a simple off-grid solar setup, built around EasySolar 48/5000 and LiFePo4 Batteries.

My goal of the setup is to have one normal european AC 230V-16A output, so that i can plug in for example a washing machine (most of them reach 3200W while heating the water), or simply all electronic products suitable for AC 230V outlets. That is why i chose the EasySolar 48/5000, that offers around the wattage necessary. Also the ability to load this with an external power source. So this is fix.

About the size of the batteries, i am not sure yet if i need double Ah, or if 100Ah is enough, but this is easy to exchange, when i know that all other components are in a correct setup.

I would really appreciate someone looking at the simple setup plan to check:

- if all the components kind of fit and work together,

- if some important parts are missing,

- if it could be simpler or less components (= cheaper, but i dont think so, its super simple already),

- what special connection cables i need, that dont come with the main products,

- is a 250A Fuse behind the batteries right? (the BatteryProtect has a Maximum Peak Current of 250A so i figured this would be fine...)

I am new to Lithium-Batteries and the VE.Bus BMS, so especially there i am not sure, if all connections are correct. Or if the VE.Bus BMS is the right BMS for me... Also i saw inverted and non-inverted remote cables. What do i need?

- do i need something like a battery balancer? it seems to me that it does not make sense with Lithium-Batteries...or am i wrong?


Im looking forward to someone leaving a statement to this setup and my questions.

Thanks in advance :)

Smartsolar 75/15, Hardcoded Voltages of load output mode "always on"?

Hi Smartsolar- Users :-)


I run a SmartSolar 75/15 together with 12W Solar Panels und a 12V (4S) Winston LiFeYPo 90Ah Battery in my Caravan.

Battery setup is kind of "90% full is enough -Setup" with 14V/13.4V/14.3V/30days balancing. HAve 1,7A Balancer boards on every cell.


Usually, i run the load output in mode "always on" when i use the caravan.

ATM, i am on holiday in Kühlungsborn at the Baltc Sea Coast, where Weather was quite bad. So i only got 130Wh loaded into the Battery the last 4 days, while i used 880 Wh for TV etc., all shown on the Victron Connect app.


Today, i noticed (from my gas warner beeping all the time when getting power, was the only device obn battery power at that time, taks 0,1A) that the load output switched off and on every few seconds. So i checked the battery voltage in the app: as far as i remember, it was at 13,2v.

That is way to early to switch off the battery power; these cells do have ca. 1200 Wh from 4,1V down to 3V/ cell.

Date shown here: https://www.faktor.de/batterien/einzelzellen/winston-lfypo4/lyp090aha-lifeypo4.html


Now, i changed the load output mode to user "defined 2" with off <12V and on >14,4v


I thought "Aways on" would mean" always on? Does anyone know if there are voltage limits in mode "always on"?


Best regards from Germany...
