MPPT Charge Controllers

The MPPT Charger is a high-efficiency MPPT-based DC power conversion system designed for solar and hybrid power applications. It converts DC power from photovoltaic (PV) panels into regulated –48 V DC output, enabling reliable power supply for telecom, energy storage, and DC infrastructure systems.

Designed with advanced Maximum Power Point Tracking (MPPT) technology, the PU3000 ensures optimal energy harvesting from solar panels under varying environmental conditions. Its compact, high-efficiency architecture makes it ideal for modern telecom and renewable energy installations.
