Quick Answer
Yes, you can run Ubiquiti devices on solar power alone, but you'll need a sufficient solar panel setup and a reliable battery bank to ensure stable power.
Power Requirements for Ubiquiti Devices
Ubiquiti devices, such as the EdgeRouter, UniFi Security Gateway, and airMAX radios, typically require a 12V DC power supply. The power consumption of these devices varies, but here are some examples: the EdgeRouter Lite uses around 5W, while the airMAX AC LR uses up to 10W. To run these devices on solar power, you’ll need a solar panel system that can generate at least 10-20W of power per device.
Solar Panel Setup and Battery Bank
For a typical off-grid setup, a 200-400W solar panel array with a battery bank of 12V, 100Ah or larger is recommended. This setup will provide enough power to run multiple Ubiquiti devices, including a long-range bridge, during periods of low sunlight. It’s essential to choose a solar panel with a high efficiency rating (around 20-22%) and a battery with a deep discharge capability to ensure reliable performance.
Off-Grid Considerations
When designing an off-grid solar power system for Ubiquiti devices, it’s crucial to consider factors like voltage drop, cable loss, and temperature effects on battery life. Use a voltage-stabilizing solar charger to maintain a stable 12V output, and ensure that your battery bank is sized correctly for the number of devices and usage patterns. Additionally, consider using a UPS (Uninterruptible Power Supply) to provide a short-term power buffer during periods of low sunlight or at night.
