Usually charge controllers have settings to calibrate the voltage display reading. As explained above use a multimeter to confirm ctuall voltage. Then you will know and can go from there. Which battery did it autodetect and did it autodetect the right one? 12.7 volts for a lead-acid bat at full charge seems low.
To diagnose a potential issue with your solar charge controller, measure the voltage using a multimeter. If the voltage is lower than expected, it might be time to recharge or even replace it. For a thorough assessment of the overall health of the solar charge controller, carefully inspect the controller. In my two decades as a solar expert, I’ve found this to be an essential step.
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. 4.2. The display segments are faint or missing The screen is blank or faint, but the back-light is still operational.
The solar charge controller 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. Another reason could be a drained battery in your solar system. The display won’t wake up if the panels are not generating enough power or if there's a wiring issue.
Reset the Controller: Sometimes, simply resetting the controller can resolve the issue. Disconnect the controller from both the battery and the solar panels, wait a few minutes, then reconnect, starting with the battery first and then the solar panels. 3.
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. 4.2. The display segments are faint or missing
The issue could also be due to insufficient solar power input. The display won’t wake up if the photovoltaic panels are not capturing enough sunlight, or if there’s a problem with the wiring from the panels to the charge controller.

Check the inline fuse between the battery and the controller and your battery and terminal block connections on the controller. If the controller is in an error state first try a soft reset. This is done by holding down all 4 buttons on the front of the controller for 15 seconds. If this does not work a hard reset is required. Remove all 4 ...
At north of $500, this is among the most expensive solar charge controllers out there, but if you have an extra large solar system of over 1,000 watts to power your luxury Class A motorhome that''s equipped with power …
In the settings menu the solar charger and SmartSolar Control settings can be viewed and/or changed. Caution Do not change settings unless you know what they are and what the effect of changing these setting can be.

Does your charger display the temperature it is seeing from the sensor? That would let you check your extended wiring with a known temperature thing, say boiling water. Of course if your charger does display the temperature you could tap your sensor in and then check to see if the readings make sense. k type thermocouple j type thermocouple

Does your hand held meter only register 12.9? You need at least 3 1/2 digits so it can read 12.87, and if it is accurate you can be confident it is somewhere between 12.85 ad 12.89 Data sheet says, "Temperature Compensation: -3mV/℃/2V" - (Apparently per cell) wonder if its ADC has enough bits to resolve 18 mV, even though it doesn''t display it?

Problem: Sensors in solar charge controllers are critical for measuring various parameters like temperature, voltage, and current. Faulty sensors can lead to incorrect readings, which might mislead the controller into making erroneous decisions about charging rates or even shutting down the system.
Dynamic Adjustment: As sunlight intensity, temperature, and other conditions change throughout the day, the solar panel output fluctuates.MPPT charge controllers track these changes and adjust the voltage to extract the most energy possible. Increased Efficiency: Without MPPT, excess energy is wasted if the panel voltage doesn''t align with the battery''s charging voltage.
Solar differential controllers control the pump by turning the pump on when the solar panels reach a temperature 8-12 degrees above the temperature of the water in the storage tank. The pump pump continues to run until the temperature reaches the set high limit temp usually 130- 150 degrees.
How Does a Solar Charge Controller Work? Solar charge controllers work by monitoring the voltage and current from the solar panels and adjusting the charging process accordingly. Here''s a simplified explanation of how they work: The solar panels generate DC electricity from sunlight. The charge controller measures the voltage and current from the solar panels. If the batteries …
To determine if a solar charge controller is faulty, start by reading the controller''s LED display for any error codes or unusual indicators. You can also use a multimeter to measure the power output from the controller to ensure it is delivering the …
This may be due to low ambient temperature. If the ambient temperature is below -10°C (14°F), the LCD segments can become faint. Below -20°C (-4°F) the LCD-segments can become …
pumps do not have a control panel display) and do not display "Ext Ctrl." The SolarTouch controller can cool the pool/spa by circulating water through the solar panels when the solar collectors are at a lower temperature than the pool/spa water (typically at night). Cooling must be enabled in the Cooling Menu. The default setting
