Solar-Powered PoE Switch for Remote Sites

The Ubiquiti SM-SP-40 integrates a four-port 10/100 Mbps switch with 24V passive PoE and an MPPT solar charge controller. It accepts PV panel input through H4 connectors and delivers up to 40W from a 24V DC terminal. The unit operates from -20 to 50°C and weighs 650 g.

Installers Running Off-Grid Cameras or Sensors

This device suits deployments where mains power is unavailable and a single solar panel must charge a battery while powering multiple PoE endpoints. Buyers who need more than four PoE ports or require gigabit data rates should consider a different switching platform.

Maximum 40W Total PoE Budget from Solar Input

The 24V DC output is limited to 40W, which caps the combined power available for all connected PoE devices. Verify that the total draw of your cameras, radios or sensors stays within this limit before purchasing.

Questions about this item

How can I confirm the SM-SP-40 is charging and switching correctly after installation?

The unit is remotely managed; log into the controller to verify MPPT charging status, 24V PoE output on all four 10/100 Mbps ports, and the 40W DC terminal voltage.

What ships with the SolarPoint and what must I source separately?

The SM-SP-40 appliance arrives with H4 connectors for PV panel input; you must supply the solar panel, 24V battery (SLA, AGL or AGM), Ethernet cables and mounting hardware.

Which SolarPoint version should I choose for a 24V off-grid site needing four PoE devices?

The SM-SP-40 is the single model offered; it delivers 24V PoE on four 10/100 Mbps ports, 7A MPPT charging and a 40W DC output from one unit.
