Product: TriStar MPPT 600V with disconnect box
System size: 7.2 kW of solar, 15-kW generator, 3,000-Ah, 48-V battery (two sites)
Partners: Sunwize, Howell-Mayhew Engineering, East Penn Manufacturing, OutBack Power
Sunwize chose the Morningstar TriStar MPPT 600-V controller for a Verizon facility in Canada because the device could withstand arctic regions with temperatures of -67°F to +86°F (-55°C to +30°C). The controller’s long wire-runs, reliability and ease of installation to produce a low angle of incidence were also considerations for its selection. In addition to solar, the project included a generator that used four, 3.6-kW OutBack Power inverters on a custom control panel. This generator hybrid project saved 70% on fuel consumption for off-grid cell towers with a microwave uplink.
