Advanced Remote Telemetry & NDAA-Compliant Security Deployment
Engineered to meet government and enterprise compliance requirements, the Ubiquiti SM-SP-40 provides a secure, NDAA-compliant foundation for remote site installations. It combines maximum power point tracking (MPPT) intelligence with direct cloud telemetry, giving operators real-time visibility into PV solar panel generation, battery state-of-charge, localized weather forecasting services, and port-by-port power draw through the Ubiquiti ISP Application (UISP). The integrated 4-port Ethernet switch delivers controlled 24V Passive PoE output with priority load-shedding options to preserve long-term battery health during low-sunlight conditions.
Maximum Power Point Tracking (MPPT)
Continuously optimizes solar panel conversion efficiency to supply up to 7A of charging current to 24V battery systems, harvesting optimal power during varied weather conditions.
Managed 24V Passive PoE Ports
Features 4 10/100 MbE Fast Ethernet ports delivering configurable 24V Passive PoE, enabling remote power cycling and scheduling for airMAX bridges and surveillance devices.
UISP Centralized Remote Telemetry
Monitors PV input voltage, charge current, ambient temperature, and power usage via UISP software, giving network administrators predictive power analytics and instant offline alerts.
Weatherproof IPX4 Enclosure
Built with UV-stabilized polycarbonate housing rated IPX4, designed for exterior wall or pipe pole mounting (35 to 60 mm outer diameter) in unconditioned remote environments.

Is the Ubiquiti sunMAX SolarPoint (SM-SP-40) NDAA compliant?
Yes, the SM-SP-40 is explicitly designated as NDAA compliant by Ubiquiti, making it suitable for US federal projects, government contracts, and enterprise sites requiring compliance.
What battery types can be connected to the SM-SP-40?
The unit supports 24V (or 2x 12V in series) Sealed Lead-Acid (SLA), AGM, and Gel lead-acid battery banks with software-configurable low-voltage cutoff parameters.
How do I power 802.3af/at standard PoE cameras with 24V Passive output?
Because the SM-SP-40 supplies 24V Passive PoE, powering active 48V 802.3af/at devices requires an inline step-up converter such as the Ubiquiti Instant 802.3af Gigabit Adapter (INS-3AF-I-G).
How is the unit configured initially on-site?
The SolarPoint includes a built-in Wi-Fi management AP. Installers can connect directly to the local Wi-Fi interface using a smartphone or tablet via the UISP app for quick initial setup.
