Yes, it is possible to charge a battery and use electricity from solar power simultaneously. This scenario typically occurs in systems that have a solar panel connected to a battery bank, which then powers various devices or appliances.
Here’s how it typically works:

1. Solar panel charging the battery: When sunlight is available, the solar panel generates electricity and charges the connected battery. The solar charge controller regulates the charging process, ensuring that the battery receives the appropriate voltage and current.
2. Using electricity from the battery: The battery stores the electrical energy generated by the solar panel. This stored energy can be used to power devices or appliances connected to the battery. The energy flows from the battery to the connected load, providing power for your intended use.
3. Simultaneous charging and usage: In a well-designed system, it is possible to charge the battery while using electricity from it at the same time. The solar panel continues to generate electricity, and any excess energy not immediately required for the connected load can be used to charge the battery. This allows for a continuous power supply, even during periods of high demand or reduced solar generation.

However, it’s worth noting that the simultaneous charging and usage will depend on various factors, including the capacity of the solar panel, the battery’s charging rate, and the power requirements of the connected load. It’s important to ensure that the system is appropriately sized and designed to handle both the charging and usage requirements simultaneously.
Additionally, it’s advisable to consult the specific instructions and guidelines provided by the manufacturer of your solar panel, battery, and any associated charge controllers or inverters to ensure proper operation and compatibility of the components.
