  • Cost-effective alternative to AC line extension
  • Reliable power where you need it, when you need it
  • Minimum of six days of design load autonomy
  • Engineered for pole or pad mounting, and rapid field deployment


Applications include: Security systems, traffic systems, emergency power, cathodic protection, navigational aids, WiMax and SCADA.

Solar Power Systems (SPS) can be configured to provide a range of DC or AC power outputs. Systems include the most recent advances in PV manufacturing, electronic controls and power management. Standard controls include temperature-compensated 3-stage battery charging, battery low voltage disconnect, lightning protection and complete circuit protection. Each system comes with a two-year limited warranty (extended warranties are available), while the PV modules carry a 20 to 25-year performance guarantee.

The SPS design incorporates a minimum of six days load autonomy, providing reliable power with no operational or maintenance costs and near-zero annual load loss probability. Systems are engineered for pole or pad mounting and packaged for easy installation.

Options Include: Multiple output breakers, data logging of system operating parameters, alarm outputs for critical system parameters, DC to AC inverter for AC loads and additional enclosure for customer use.
