MPPT Charge Controllers
In solar power and hybrid energy systems, inefficient charge regulation often leads to poor energy harvest, unstable battery performance, and premature component wear, undermining system reliability and increasing lifecycle costs. The MPPT Charge Controllers by Intelux solve these challenges with advanced Maximum Power Point Tracking (MPPT) technology designed to optimize solar energy capture and ensure efficient, stable power conversion from solar arrays to storage. Engineered for commercial PV installations, off-grid systems, telecom towers, industrial energy solutions, and hybrid DC power platforms, these MPPT charge controllers deliver maximum energy yield, superior battery protection, adaptive temperature compensation, and reliable operation — making them an ideal choice for facility managers, renewable energy consultants, and EPC decision makers focused on performance efficiency, energy optimization, and long-term operational value.
Construction Details:
Housed in a robust metal enclosure, MPPT charge controllers are designed for both indoor rack-mount and outdoor IP-rated cabinet installations. Enclosures feature corrosion-resistant finishes, thermal ventilation (Forced air cooled). Standard designs comply with telecom safety and EMI standards, with secure cable entry and grounding points.
Benefits:
- MPPT Technology with higher solar energy utilization.
- Advanced circuit topology with higher efficiency and power loss.
- High energy & high efficiency design.
- High power design, only 2U width & 1U in height.
- Front easy access for DC input.
- Wide operating temperature.
- Share the same CSU and back plane with Intelux new generation rectifiers.
