There is a good chance that you may see there is voltage but no amp (which means current). Why? Solar panels having voltage and no amps are mostly caused by an open circuit. In simple terms, it means your circuit is incomplete or flawed. Causes include using wrong voltage, wrong Connection, problems with panels or solar charge controller.
Another take-away from the chart above is that if you notice your battery at a low voltage while you''re pulling loads, say 11.8V - a pants-pooping level - fear not. If you remove the loads and observe the battery voltage to rebound upwards (without charging), that rebound voltage is more indicative of state of charge than the loaded voltage.
To power the ESP32 through its 3.3V pin, we need a voltage regulator circuit to get 3.3V from the battery output. Voltage Regulator. Using a typical linear voltage regulator to drop the voltage from 4.2V to 3.3V isn''t a …
The Fluke clamp meter I linked was 2% +/-5 counts for current, 1% +/-5 counts for DC voltage. It would seem 1% is barely good enough for lead-acid batteries, because we want to fully charge them. For LiFePO4 people might think they want better accuracy, but maybe balanced to 3.65V and operated to 3.4V it doesn''t really matter there either.

A charge controller, or charge regulator, is basically a voltage and/or current regulator to keep batteries from overcharging. It regulates the voltage and current coming from the solar panels going to the battery. Most "12 volt" panels put out about 16 to 20 volts, so if there is no regulation the batteries will be damaged from overcharging.
Here are the steps to check the solar charge controller: The solar charge controller is the main unit for a solar charging system, so any fault within the controller will stop the battery from charging. First, visually inspect the display of the solar charge controller to check the amount of amperage and voltage coming from the solar panel.
Regulate Current: The controller must effectively manage the flow of current to the battery to prevent overcharging. ... Fluctuating battery voltage in solar charge controllers often necessitates employing effective troubleshooting methods to …

Could be that applying a voltage to meter leads while in that setting causes erroneous reading. Three panels in series would all have identical current, so 1.8A each is good. Was that clamped around wire? Voltage would be 3x a single panel, so 131V or 44V/panel is good. Power is about 80W per panel, so probably battery is near fully charged.
Current represents one of the most serious safety hazards in an electrical circuit, and it must be accurately measured when working on PV systems. Technicians use current measurements to confirm proper system operation. More commonly, current measurements verify that zero current is flowing and the circuit is safe for interaction.
