Solar Power Supply

SPS-6-15

The SSI SPS-6-15 Solar Power Supply is the 15VDC output variant of our SPS-6 dual-panel solar power system, designed for remote metering and telemetry installations requiring a regulated 15VDC supply where AC line power is unavailable or a renewable source is preferred. It includes all SPS-6 components pre-wired and ready to deploy: two 30W solar panels, mounting bracket, charge controller, interface circuitry, a 50Ah battery, and a 16″ x 12″ x 6″ NEMA 4X ABS enclosure.

The SPS-6-15 provides approximately two weeks of holdover at a 20mA load with no additional solar input, and recharges in approximately 6 hours under good conditions. Installation requires only mounting the enclosure and panels on the supplied bracket and connecting the load.

Product Highlights

The 15VDC output variant fills the gap between the standard 12VDC SPS-6 and higher-voltage applications, and is appropriate for devices requiring a regulated 15V supply — including certain relay, telemetry, and communications equipment that operates above standard 12VDC levels. The dual-panel design and large 50Ah battery provide robust energy reserves for demanding applications.

As with all SPS-6 variants, the pre-wired all-in-one packaging eliminates component sourcing and ensures a consistent, weatherproof installation.

Features

The SSI SPS-6-15 delivers 15VDC output from a dual 30W panel solar power system with a 50Ah battery and two-week holdover in a NEMA 4X enclosure for remote installations.
  • 15VDC regulated output — 1A maximum output for devices requiring a regulated 15V supply.
  • Dual 30W solar panel input — two panels deliver higher charging capacity for demanding loads or lower-sunlight conditions.
  • 50Ah battery with ~two-week holdover — sustains a 20mA load for approximately two weeks with no additional sunlight.
  • Complete turn-key solution — includes two solar panels, bracket, charge controller, interface circuitry, battery, enclosure, and hardware.
  • Pre-wired NEMA 4X ABS enclosure — 16" x 12" x 6" raintight and dustproof housing with all components pre-installed.
  • ~6-hour battery recharge time — rapidly restores battery under good solar conditions.
  • Temperature range -38°C to +70°C — rated for demanding outdoor environments.
