Victron Energy Blue Solar Charge Controller Mppt 75 1 10 Manual Wiring Diagrams Assistance
Standby current of SmartSolar charge controller MPPT 75/15 outside spec? On my recently installed SmartSolar charge controller MPPT 75/15 I measured a standby current of 30 mA, whereas the datasheet states 25 mA at a supply voltage of 12 V.
I also observed electric sparking when connecting the charge controller to the battery, indicating a pretty high peak current even beyond the measured 30 mA.
I would like to know, if my MPPT might have e. g. internal leakages and should be replaced, or if this type of MPPT is being delivered into the market even with current consumption higher than specified.

Using Victron MPPTs with multiple angled solar arrays Hallo!
Meine Frage: Ich habe den Oben angeführten Laderegler, ist es mit diesem Laderegler möglich die Photovoltaikmodule an Ost und West zu Montieren?
Wie verhält sich der Laderegler bei so einer Montage? (Fährt er in den Keller wegen der Abgeschatteten Seite)
Google translation:
My question: I have the charging controller mentioned above, is it possible to assemble the photovoltaic modules at East and West with this loading controller?
How does the charging controller behave with such a montage? (Does he drive to the basement because of the shaded side)
Vielen Dank für die Hilfe

MPTT state off Hi
I have a SmartSolar that remain in off state forever:
[image]
The remote switch is short circuited and everything seems to be properly working except that battery state remain off. The battery is 90% charged and I have AC turned on so there is a significant load going on (700W).
What is weird is that historical data shows there have been some production although as far as i can tell the solar charger (which is turned on in the SmartSolar settings) always remained off:
[image]
What I can do to further diagnose the issue???
Thanks
Stefano

custom mppt charging advice needed Hi
I have a pair of Leoch 130 AGM batteries
I would like to set the correct settings in the Smart MPPT solar control 150/45 to match the datasheet for the batteries.
But I don't quite understand how to set this up correctly with the Victron Connect app settings.
The datasheet has
Cycle Use - Initial Charging Current less than 27.0A.Voltage 14.4V~15.0V at 25 C(77 F) Temp. Coefficient -30mV/0C
Standby Use - No limit on Initial Charging Current. Voltage 13.5V~13.8V at 25 C(77 F)Temp. Coefficient -20mV/ C
My guess is the Cycle usage is Absorb and the standby use is float? They seem to have different temp coefficient and there seems to be only 1 option on the controller.
So whats boost?
It also has ~15V so assuming they will accept up to that and that can be my max absorb setting?
I've only just installed it but don't want to set anything up that will dmg the batteries.
I have 650W (2 x 325W in series) so it will get up to the 45Amp charger current if the batteries are needing it and the sun is out midday im expecting,
The spec sheet: https://www.alpha-batteries.co.uk/media/catalog/product/l/a/lagm-130.pdf
charge mode
A: With switch regulator (two-step controller) charge on curve max.charge voltage for max.2 hrs/day then switch over to continous charge
B: Standard charge without switching
C: Boost charge (Equalizing charge with external generator) charge on curve continous charge for max. 5 hrs/month, then switch over to curve Standard charge
But I haven't got a clue what that means. Or how to interpret it into how the settings are presented in The VictronConnect app for the mppt controller.
The sheet doesn't have any thing i can see about Equalisation either and no idea if its safe to do that on these.
I have them in parallel so running at 12v.
Is equalisation like reconditioning? to try and de-sulphur the plates?
Does the above "A" mean i set the max absorption time to 2h?
Thanks in Adv if you are able to provide any understanding that i clearly lack about charging batteries.

MPPT 75 10 both indicators blinking Hi I have 2 50watt panels connected to a Victron 220ah AGM battery,which I also charge through a Victron centaur 12/30charger when connected to shore power. Both the green and yellow lights blink. The pannels are connected to the PV terminal and the battery to the battery connection. Why do both lights continue to flash?. Have I set it up wrong or do I need to add other controls.

How can I save long term history records? Hi,
I just installed my equipment and it seems to be running fine for about two weeks now.
I am wondering how i can record the energy that is produced. Not only for the last 30 days (as I undestood is done by the MPPT) but just for the upcoming months and years.
A friend of mine has solar panels for at least 4 years now and his app is able to read back all the energy his system produced, by the year, month, week and even per day.
How can I get / record this sort of information with my setup?
thanks,
Charles

Long Wire Runs to Battery From MPPT 100/15 I have looked via the search and not found a clear answer..
To save running additional wires through already crowded firewall grommets is it a no-no to use existing circuits?
This is a LandCruiser 4x4 in which there already is a Bluesea busbar for chassis ground inside the vehicle, via 4 awg marine Ancor wire. The battery in engine bay is to chassis ground via 2 awg Anchor marine wire (all lugs properly crimped).
For positive circuits to the interior there is an 8 awg (20 amp maxi fuse at the battery) to the back of the vehicle with distribution via a Blue Sea fuse box.
There is also a 4 awg marine Ancor positive wire circuit to a busbar at the back of the vehicle for an air compressor and inverter, fused with a resettable 70 amp Cooper Bussman breaker at the battery.
Both the 8awg and 4 awg runs are 12' to 14' runs from the battery.
What downfall would there be of running the output (battery side) 0f the MPPT 100/15 battery + connection to either of the positive circuits and using the chassis ground circuit for the battery – connection, instead of a new run (would use ancor marine 10awg if needed). The circuits are oversized for what is needed for the 100/15 so resistance and drop are minimized if I've figured things correct.
The solar panel positive and negative will be direct to the MPPT 100/15.
The Load side of the MPPT 100/15 will not be used.
Thanks for your thoughts and ideas.

Use of a bench DC Power Supply as PV input to a Smart Solar Charge Controller I have an external system that ties into my Victron system via a Modbus TCP connection to my CCGX. My need is to refine some tuning parameters in the external system. To do this I need to control the PV voltage and amperage inputs to my Smart Solar 150/45 controller wired to a 48V battery bank. I will do this by removing the PV Panel connections and using the Power Supply instead.
Testing output from the Bench Power Supply will range from 60-75V and 0-33A, not to exceed 1200W total output power.
Are there any risks to the charge controller during this test scenario?
Just want to make sure I don't fry something.
Thanks,
Pat

75/15 MPPT output not what is expected Facts:
- Solbian CP125 (125w) solar panel. Data sheet here: https://www.emarineinc.com/pdf/Solar Panels/Solbian_CP125.pdf
- Victron Blue Solar MPPT 75/15 controller.
- Battery is a brand-new Deka Group 31 12v battery.
Symptoms:
- Controller power output consistently reads lower than expected for prevailing solar conditions. (Perfect alignment, perfectly cloudless days)
- Voltage output from panel to controller (indicated): 14 to high 15's
- Amperage output from panel to controller (indicated): 1.5 to 3 amps
- Total power from panel to controller (indicated) usually in the 20 - 30 watt range, highest ever recorded was 56 watts for a 125 watt panel
- Values recorded with battery at various depths of discharge, various electrical loads applied. This doesn't seem to affect the output of the controller.
- Indicated outputs from controller to battery are similar, voltages usually a bit lower than what the panel is shoving into the controller.
Tests conducted so far:
- Triple checked all wiring connections for tightness and correctness in accordance with the manuals of the panel and the controller
- Disconnected panel from wiring run and controller. Multi-meter indicates 127.75 watts output (17.5 volts out, 7.5 amps out=127.75) Panel seems healthy.
- Connected panel to wiring run and controller. Meter indicates 93 watts at the end of the run, measured at the controller terminals.
- Note: I do have an excess length of wire because I wanted the ability to move the panel higher, later if I desired. Possible voltage drop due to lengthy cable run?
- In spite of the fact that I measure 93 watts at the end of the cables, the controller still indicates only in the 20's to low 50's wattage input from the solar panel. Why?
I've had this panel and controller for a couple of years. It's always output this low. Yes, I'm an idiot and never questioned why until recently. Let's skip past that and get to the possible causes.
The only causes that spring to mind are faulty controller or wiring run is too long, causing an excessive voltage drop. I figure the total run is 30-40 feet of cable with MC-4 connectors on the panel itself.
Lastly, there's one little statement in the Victron manual that gives me pause:
12V battery and mono- or polycristalline panels connected to a 75V controller ● Minimum number of cells in series: 36 (12V panel).● Recommended number of cells for highest controller efficiency: 72(2x 12V panel in series or 1x 24V panel).● Maximum: 108 cells (3x 12V panel in series)
Notice that the manual states that the "minimum" number of cells is 36. My Solbian panel only has 32 cells. Could this be the problem?

MPPT 150/70 solar panels Voltage limit 4 x 270 W Axitec panels - Easysolar 48/3000-MPPT 150/70 - 4 of 200 A (12V) AGM bat in series = 48V - Multi 48/3000 in a easysolar . - BMV 700- Color control . Caribbean area.
Axitec panels are 270 W - 31,12 V 8,71 A
OCV = 38,21 V scA = 9,25 A
Good day,
I had a easysolar 1600/24 with 100/50 MPPT. My panels were in 2 series of 2 for voltage.
I now have a Easysolar 48/3000 with MPPT 150/70. I passed my batteries in 48 V.
For now, I still have 2 pairs of cables arriving from my solar panels . Accordingly there is a little difference between panels voltage and battery voltage .
I like to have far more panels V than Battery. For this one, I am hesitating.
If I put all my 4 panels in 1 serie, I will have :
- Nprmal operation : 4 x 31,12 V = 124,48 V @ 8,71 A . perfectly within MPPT 150/70 limits
- My Open Circuit voltage (max) would be 4 x 38,21 V = 152,84 V ! Slightly above the 150 V limit for the CC. However, I am in the Caribbean with hot temperatures year round ; lowest ever might be 17° C .
Appreciate comments to see if I could take the risk and have only 1 serie of 4 panels .
Thanks

over sizing of panel input to mppt good day,
shall i over size the panel input of mppt,using mppt sizing calculator with other brand solar panels,in case if exceed the input which is mention in the datasheet of mppt is it damage the controller,if it was damaged in that case is it cover warranty replacement.
