Product Highlights
The SPS-7’s dual 45W panels deliver the highest charging capacity in the SSI solar supply lineup, making it the right choice for higher-power loads, installations with limited sunlight exposure, or applications where a large energy reserve is essential for reliable long-term operation. The 75Ah battery — the largest in the SPS series — provides significantly more holdover capacity than the SPS-6 or SPS-2, and its 500mA maximum charge current keeps the battery consistently topped up under normal solar conditions.
All components except the solar panels mount inside the 24″ x 16″ x 8″ enclosure, the largest in the SPS family, providing ample space for the battery and electronics in a fully protected, weather-sealed environment.
Features
The SSI SPS-7 is SSI's largest solar supply — dual 45W panels, 75Ah battery, 12VDC output, and two-week holdover capacity, pre-wired in a NEMA 4X enclosure.
- Dual 45W solar panel input — the highest charging capacity in the SSI solar supply lineup; up to 500mA charge current.
- 75Ah battery with ~two-week holdover — sustains a 20mA load for approximately two weeks with no additional sunlight.
- 12VDC regulated output — compatible with SSI wireless pulse link transmitters and other 12VDC-powered devices.
- Complete turn-key solution — includes two solar panels, bracket, charge controller, interface circuitry, battery, enclosure, and all hardware.
- Pre-wired NEMA 4X ABS enclosure — 24" x 16" x 8" raintight and dustproof housing with all internal components pre-installed.
- ~6-hour battery recharge time — rapidly restores battery capacity under good solar conditions.
- Optional 5VDC and 15VDC output variants — SPS-7-5 (5VDC/1A) and SPS-7-15 (15VDC/1A) available for non-standard applications.
