  • Expand your wireless mesh beyond conventional boundaries
  • 24/7 power for locations without power utility service
  • Designed to provide reliable power with 7 day autonomy (cloud coverage)
  • Cost effective alternative to trenching and laying conduit where AC power is not available
  • Systems are optimized for geography regions with different solar resources

Alpha’s WiFi Solar Power System (SPS) provides portable, wireless power to outdoor wireless access points and is a less expensive solution than utility connection in many remote locations. The rugged design of the SPS makes it ideal for installations in harsh, outdoor environments. These systems are an attractive alternative to generators and are an effi cient source of energy for small loads. The WiFi Solar Power System’s features include temperature compensated PWM battery charging to extend battery life, integral lightning protection, code-compliant wiring and circuit protection. To minimize installation time and eliminate errors, these systems have pre-connectorized cables.
