Quick Answer
Yes, you can use solar power while plugged into shore power, and it's a common setup for RVs. This is known as a hybrid power system, which combines multiple power sources for optimal energy availability. The inverter and battery system will automatically switch between solar power, shore power, and battery storage.
Configuring a Hybrid Power System
When setting up a hybrid power system for your RV, it’s essential to choose the right components that can work together seamlessly. A typical setup includes a solar panel array, a charge controller, a deep cycle battery bank, an inverter/charger, and a monitoring system. For example, let’s consider a system with 2 x 200-watt solar panels, a 300Ah lithium-ion battery bank, and a 2000-watt inverter/charger.
Operating Modes
The inverter/charger will automatically switch between three operating modes: solar power, shore power, and battery power. When you’re connected to shore power, the inverter/charger will charge the battery bank and store excess energy for later use. When the shore power is disconnected, the inverter/charger will switch to battery power and use the stored energy. When the sun is shining, the solar panels will charge the battery bank, and the inverter/charger will switch to solar power.
Monitoring and Control
To ensure efficient energy management, it’s crucial to monitor the system’s performance. A monitoring system will display real-time data on solar panel output, battery state of charge, and inverter/charger operation. This information will help you optimize your energy usage, identify potential issues, and make adjustments to the system as needed. For example, you can set the system to prioritize battery charging during peak sun hours and use shore power during periods of low solar input.
