Today’s telecom infrastructure is increasingly located remote, isolated areas—from mountain tops to desert regions— which are usually far from any electrical grid and rely on on-site power generation to operate. But between fuel and maintenance costs, generators are expensive to own and operate. For communications providers, the ultimate goal is to establish self-sustainable mobile networks with higher efficiency and profitability and remain competitive in a lower Average-Revenue-Per-User (ARPU) environment.
That’s why telecommunications providers—both wireless service providers as well as BTS tower operators– are turning to solar PV and PV/Hybrid (PV + a secondary energy source) power solutions to achieve their business objectives. Unlike generators and wind turbines, photo-voltaic (PV) solar has no moving parts—so consequently, no down time. And solar electric systems never need fueling or an overhaul. This type of system can be sized and installed as the primary source of power for a remote telecom site, and the hydro, wind and/or generator-based systems can supplement PV output should “days of autonomy” be insufficient for the installation’s powering needs.
As more of the telecommunications industry shifts to solar, Morningstar’s extensive line of solar controllers and accessories are more frequently found at the core of their systems. In such a system, the charge controller is both “heart and brains” of the outfit, controlling the PV/solar-generated electricity flowing from the panels, or modules, into batteries for storage as well as the DC output to power connected loads, maintaining both system operation and battery health.
In remotely powered telecommunications installations, what matters most is efficiency and reliability. Efficiency is paramount for systems that may need as much autonomy as possible to get through long stretches without sunlight or refueling. Morningstar’s proprietary TrakStar solar harvesting technology and fanless design make for inherently more efficient systems. And with over four million Morningstars installed in the field since 1993, there’s no brand in the solar industry that’s more proven or accepted in terms of reliability.
Select charge controller models have:
This is not a quality difference, but a function of prevalent solar conditions and location considerations.
All Morningstar charge controllers, regardless of their technology or design, built to one industry-leading quality standard. They all have “over-spec’d” components, incorporate advanced electronic design and thermal engineering, and have no cooling fans to fail—unlike all the in-kind competition. Because of this, over four million Morningstars have been sold since 1993 and are the first choice for leading solar installers in mission-critical installations around the globe.
