Quick Answer
For Ubiquiti installations, the best power sources are typically 12V or 24V DC power supplies or solar panels with MPPT charge controllers, which provide efficient and reliable power to the equipment.
Choosing the Right Power Source
When selecting a power source for an Ubiquiti installation, it’s essential to consider the device’s power requirements and the available power source options. Ubiquiti equipment, such as the AirMAX or EdgeMAX series, typically operate on 12V or 24V DC power. For off-grid installations, solar panels with MPPT (Maximum Power Point Tracking) charge controllers are ideal, as they optimize energy harvesting from the sun and provide efficient charging of batteries.
Solar Panel and Charge Controller Selection
For a typical Ubiquiti installation, a 100-200W solar panel with an MPPT charge controller is a good starting point. The charge controller should be rated for the solar panel’s maximum power output and the battery bank’s capacity. For example, a 200W solar panel with an MPPT charge controller rated for 20A can charge a 12V or 24V battery bank with a capacity of 100Ah or more. When selecting a charge controller, consider factors such as efficiency, temperature range, and input/output voltage range.
Battery Bank and Deep Cycle Requirements
A deep cycle battery bank is essential for storing excess energy generated by the solar panel during the day for use during periods of low sunlight or at night. When selecting a battery bank, consider the depth of discharge (DOD) and the number of cycles required. A good rule of thumb is to select a battery bank with a DOD of 50% and a minimum of 200 cycles. This ensures that the battery bank can handle the varying energy demands of the Ubiquiti equipment and provide a reliable source of power.
