You need to use a shunt resistor to also measure the solar panel's current while measuring the output voltage. You do not say how you know whether the battery pack is being charged or not. With your solar panel, if it has sufficient power to charge at all, it may take days of bright sunshine to charge the battery pack.
What is a solar charge controller?
Solar charge controllers are designed to regulate the charging process of solar batteries, preventing overcharging and ensuring optimal battery life. They often incorporate various indicators to provide information about the battery's charge status. Here's how to determine if a solar battery is fully charged using a solar charge controller:
How do I know if my controller is fully charged?
Step 3: Identity the fully charged LED: The controller should have a specific LED that indicates a fully charged battery. This is often the green or blue LED. Step 4: Assess the battery charge level: If the fully charged LED is illuminated, the battery is considered fully charged. If not, the battery needs more charging.
How do you measure a solar battery?
Measuring stationary solar batteries with a DMM voltmeter is best, but portable handheld voltage testers also work well. Built-in analog volt meters eliminate guesswork by reporting the actual battery voltage, which maps to the state of charge levels. However, the relationship between volts and charge percent varies by battery chemistry.
How long does it take to charge a solar panel?
Charging time depends on: Under ideal sun conditions, size compatibly matched panels and batteries refill charge in 4-8 hours for lead acid or 2-3 hours for lithium ion. For example, a 400-watt solar panel system should fully charge a 400 Ah lead acid battery bank in about 8 hours at best solar irradiance.
