Ive dismissed the SOC / battery capacity readout as this seems to be random at best. After sun down with hardly any load the battery (ive disconnected the inverter to rule that out) voltage tails off and last night went down to 12.11v (50% soc?) this is with no load bar the SCC being connected to the batteries.
The display is powered from the solar charger. The solar charger is powered from either the battery or the PV array. If the PV voltage and the battery voltage are both below 6V, the display will not power up. It could also be that the LCD display is not properly inserted into the socket on the solar charger.
Not seeing any solar wattage display on Victron app. Have 75/15 controller. MPPT SmartSolar. screen-shot-2021-04-28-at-103802-am.png (252.5 KiB) The smartsolar will not start charging until PV voltage is 5 Volts higher than the battery voltage. see note 1b) on

Believe they use LiMnO battery chemistry, and I think pack is 14S, 4.2v max charge voltage on cells. About 58.2 vdc is maximum pack charging voltage. Hope you have an internal BMS working for them. You need to set up your inverter charging parameters properly. Voltage drop is another issue. but you need to fix the inverter charging setup
Battery Voltage Fluctuations. How do battery voltage fluctuations impact the performance of a solar panel system? Fluctuating battery voltage, stemming from issues like inadequate sunlight exposure or loose connections, can greatly affect system efficiency and longevity. Monitoring battery voltage regularly is important for detecting
But the M2012 SMD devices I mention above are more likely to be used in the voltage divider strings that measure battery voltage, among other things. Since the battery voltage is significantly lower than the bus voltage or
So the DC Voltage at the PV input terminal shows only 12.30V, that is too low for the MPPT to be able to charge the 12V battery, it has to be 5V above the battery Voltage, so around 17 ~ 18V or more.
The solar charger is powered from either the battery or the PV array. If the PV voltage and the battery voltage are both below 6V, the display will not power up. It could also be that the LCD
What does the voltage at the battery connection terminals on the inverter show when read with a multimeter?

Battery voltage threshold: The load output might be deactivated to safeguard the battery. This occurs if the battery voltage drops below the set threshold. Check the battery voltage and load
Our multi meter also displays at the battery input on the victron the same incorrect voltage. Does any one know why there is a discrepancy in the battery voltage readings between the victron dashboard and our multi meter and 2 other gauges we have that display leisure battery voltage. in the battery voltage readings between the victron
High battery voltage alarms appeared straightaway along with the loss of PV inverter monitoring as previously posted. I reverted back to v2.51 and the high battery voltage alarms disappeared but I went back to exceeding my grid feed in limit. Updated to v3.50 and PV inverter monitoring was restored but high battery voltage alarms returned.
You need to use your DMM (digital multimeter) direct on the MPPT terminals and the battery terminals to see if the voltage is higher at the MPPT than at the battery. If the DMM reads high then you have a poor connection somewhere such as the MPPT terminals or
It just seems odd that the voltage display went blank in the 4th picture. But it is still showing the 129 amp current. If you still have voltage at the battery terminals, the trip is happening external. If the batteries are shutting off, that would answer all the questions. The capacity and % are wrong but the voltage is still 13.2 and
Battery voltage is decent (for AGM), SCC display is way off. Have to consider "12.4" to mean 12.3V < reading < 12.5V Probably means its settings are off as much. Measure and observe how high it charges battery, decide if actual performance is acceptable or not. If not, upgrade to some other brand.
Reconnecting or replacing the lines may be necessary to get your display working again. 3. Battery Voltage Is Too Low. Sometimes, your battery voltage can drop so low that it sends your charge controller into sleep
It''s reporting the capacity and SOC correctly but the battery voltage shows 5.0V instead of 50.20V. It seems that the inverter is calculating the reported voltage wrongly
5) Applied continuous AC load - Battery voltage reduced due to load but SOC on VRM still showing 95%. 6) Applied AC load to drain battery and for BMS to restart - battery voltage dropped, BMS restarted but SOC still at 95%. As you can see on the screen shots Battery Voltage and SOC is in the same parameter box or window.
I have one of my dc inverters that even when load drops voltage it matches the voltage on my battery. Everything perfect so far. BUT On my latest inverter the dc input voltage reading is
Why after reconnecting back to mmpt today I''m only getting 0.04amps at 38ish volts approx = 1.5watts going in to my battery? Got 390w solar panel in full sun. Mppt Battery display is 14.3 and capacity says 100% which I belive is incorrect. Surely at 30% soc, the mppt should be smashing the amps into the battery? Any help would be greatly
Solar panel 100W then connects to SCC and starts charging, with custom settings set to 13.8V bulk/termination voltage. When it reaches the set point, battery and scc
The problem is that the batteries are now about 100% charged because the voltage has reached the absorption value of about 57.5 V. I have checked that the battery
The Battery voltage (12/24/36/48V) is set incorrectly. Use VictronConnect to set the right Battery Voltage. There is another device connected to the battery, which is configured to a higher
Can see battery voltage - so far so good!. I did notice that SOC went down to 6% suddenly!? after 5 mins or so is this normal. However - PV input remains at 0, tried tripping PV isolator doesnt seem to do anything. Panels are in 1 string of 10 series voc 417.6 9.86A (Inverter should be able to handle 500Vdc )
When charging the MPPT will have a higher Voltage than the battery which causes a current to flow from the charger to the battery. When a current flows through a wire there will be a Voltage drop. The ammount of Voltage drop depends upon a) the resistance of the cable and b) the ammount of current flowing.
One of the 100/30s and the 100/15 show battery voltage at the controller that matches the voltage meter on the boats electric panel. The voltage on the bus bar is also consistent with these
The solar charger starts charging when the PV voltage is 5V above the battery voltage. Charging continues if the PV voltage remains 1V higher than the battery voltage. To verify the "battery voltage" setting, use the VictronConnect app or a connected display. If the setting is incorrect, make sure to adjust it to the correct battery voltage
You may be thinking something is wrong with the panel itself. And you are exactly correct. Remember to use quality batteries. And always remember battery voltage should be less than panel voltage. 3. Solution to Extreme Weather Condition Tips on Fixing Solar Panel Draining Battery . Aside from Diodes, there are also many things you need
Good day, guys! I am currently doing a project on the solar panel, and I am at the last step, which is to measure the voltage and current of the solar panel so as to know the power to display it on my dashboard. However, I am with a problem. So my voltage value was correct when I haven''t connected it to the charge controller but however, when I connect it to
I have seen others post similar issues, i believe i have tried a large portion of those solutions and whilst it may work for a day or 2, the MPPT will get out of sync and read the wrong voltage and go into the incorrect charging mode and the batteries slowly discharge during the peak of the day.
The controller display is an indication of state of charge during charging only, it is based on voltage alone, when there is no PV input the battery % value will correspond whth the battery voltage. With a typical lead acid battery the
At this moment I set Battery Capacity as 310Ah, and the BMS app displays 56.17V, Average cell Voltage: 3.51V and Remain Battery: 100%. The highest voltage on a cell is 3.53V. I suspect the cell voltage should be 3.6V when remain Battery is 100%. Can someone explain how to understand above info?

PV and AC charge. The inverter display is normal on-grid and running with limited PV power and low battery. If the inverter charges the battery from the PV power or the AC, the solar inverter display will be shown on the status. Battery grid off. The solar display typically runs off-grid without any input PV power, and there''s sufficient
We have an installation where the Smart Solar MPPT 150/100 is measuring the voltage 2V above the real voltage from the Pylontech batteries. This resultss in solar charge
Hello, i have tried to monitor voltage of an input solar panel to charge battery. When there is an input, the GPIO34 displays the charge voltage (solar panel voltage). When there is no input (only the battery), the GPIO34
This is my first post as I have a question pertaining to the Victron BMV-712 battery monitor. Mine displays an inaccurate State of charge. I have a battery bank with 6 x 100Ah Battle Born batteries and the BMV-712 always shows a State of Charge lower than reality. Once I reach 0% state of charge, I can usually consume another 250Ah +/-.
Secondly, the issue could also arise due to insufficiency of solar power input. The display won''t wake up if the photovoltaic panels are not capturing enough sunlight, or if there''s an issue with the wiring from the panels to the charge controller. Now, turn your attention to your solar system battery. Measure the voltage using a
During the surge the voltage goes as low as 9.8 volts then is constant between 11.8v and 12.2v before sounding the alarm about 5-10 seconds after switching it on. Interestingly the voltage on the charge controller screen
Measure the voltage between the positive and negative PV terminals. Confirm that the battery or the PV voltage is at least above the minimum voltage as specified in the technical specifications chapter. Check the battery and PV supply cables. Check the fuses and circuit breakers. Check if all connections are tight.
The Battery voltage (12/24/36/48V) is set incorrectly. Use VictronConnect to set the right Battery Voltage. There is another device connected to the battery, which is configured to a higher voltage. For example a MultiPlus, configured to equalise at 17 Volts, while in the MPPT this is not configured.
The display does not power up. The screen is blank and the back-light is off. The display is powered from the solar charger. The solar charger is powered from either the battery or the PV array. If the PV voltage and the battery voltage are both below 6V, the display will not power up.
The "Battery voltage" (12, 24, 36 or 48V) parameter is set incorrectly. Use the VictronConnect app to set it to the correct battery voltage. Another device is connected to the battery with a higher charge voltage configuration.
Use a multimeter set to DC voltage mode. Measure the voltage between the positive and negative battery terminals. Measure the voltage between the positive and negative PV terminals. Confirm that the battery or the PV voltage is at least above the minimum voltage as specified in the technical specifications chapter.
The unit needs to be replaced. This error will auto-reset once the battery voltage drops below the float voltage. To protect the battery from over-charging the battery is disconnected. over-sized PV array configuration, if there are too many panels in series the battery voltage cannot be reduced any further.
