A cost-efficient, quick-to-deploy off-grid solar power system to meet power needs for contractual commissioning, remote telemetry, and other long duration, remote, and low-power critical loads.

A steel outdoor enclosure built to NEMA3 standards with 5,120 Watt-hours of energy storage and a 300W inverter. The A351 can be paired easily with 1-2 standard PV modules between 240-1000W of PV. Once activated, it can power commissioning devices, remote monitors, etc. 24/7 over a period of weeks, months, or even permanently (after commissioning) without the physical presence of a worker on-site.
