Application: Solar Tracker
Power Solution: HEP-185 Series
As PV solar systems evolve, incorporating solar trackers has become key to maximizing efficiency for large-scale PV installation or so call Solar Farm. These trackers adjust panel positioning throughout the day, increasing energy capture by 25-40% compared to fixed systems, ensuring optimal sunlight exposure and boosting overall performance.
CUSTOMER PAIN POINTS:
- Harsh Environmental Durability: A reliable power supply is crucial for photovoltaic systems, especially in desert environments, to ensure consistent performance, long-term durability, and safe operation. Customers often face difficulties in finding power supplies that can withstand harsh conditions such as dust, high humidity, and temperature fluctuations. These factors can cause premature failure or reduced efficiency if the components are not designed to handle these extremes.
- Compliance and Safety Regulatory: Solar Farm Trackers typically operate at high input voltages either AC or DC because low line operation such as 110/120VAC is not preferred due to the large number of power supplies required at the Farm, which would increase cable costs and reduce system efficiency. For AC voltage system, ensuring compliance with 230VAC/240VAC/277VAC operation is crucial for the Trackers to meet International power system.
- Cable and Connector Reliability: Selecting and properly installing PV cables for the power supply that can endure harsh environmental conditions, like extreme temperatures, UV exposure, and moisture, presents a challenge. Additionally, ensuring the cables are securely terminated with waterproof connectors adds another layer of complexity.

POWER SOLUTIONS:
The MEAN WELL HEP series, combined with the expertise of the engineering team, effectively addresses the following customer pain points:
- The HEP series is IP68 rated, offering superior protection against dust, moisture, and extreme temperatures. The engineering team ensures the power supply meets the specific environmental needs of each application, minimizing the risk of failure.
- The HEP series complies to 277VAC safety standards, ensuring safe operation across international and local regulations. MEAN WELL compliance engineers support customers in selecting the right solutions to meet these stringent requirements.
- Designed to withstand harsh conditions, the HEP series supports durable PV cables and waterproof connectors. The engineering team works closely with the customer to select the proper cables and connectors that meet the specific environmental requirements, ensuring long-term reliability through proper installation.

CONCLUSION:
MEAN WELL’s HEP series directly addresses key customer challenges, offering superior durability in harsh environments, compliance to 277VAC safety regulation, and reliable cable/connectors for long-term performance. Supported by the Engineering Team, customers can trust the HEP series for a robust, efficient, and compliant power supply solution.
