DC12V24V 800L/H Solar Brushless Motor Water Pump

A 12v DC water pump can work when directly connected to solar panels without a battery, but there are some considerations to keep in mind. Solar panels produce variable voltage and current depending on factors such as sunlight intensity and angle. Without a battery, the pump may not receive a consistent power supply, which could affect its performance. Additionally, starting currents and fluctuations in the solar panel output could impact the pump's operation. It's important to use the appropriate voltage and current regulators to ensure the pump receives a stable power supply from the solar panels.
