Flin Energy is a company that specializes in the design and manufacture of solar power equipment, including solar inverters, charge controllers, and batteries. In terms of their MPPT (Maximum Power Point Tracking) charge controllers, these devices are designed to optimize the power output of a solar panel array by matching the operating point of the panels to the load on the system, ensuring that the solar panels are operating at the point where they produce the most power and that the power is delivered to the load efficiently. MPPT charge controllers are typically more efficient than traditional PWM (Pulse Width Modulation) charge controllers, and can increase the overall power output of a solar panel system by as much as 30%. This can be particularly useful in systems with high voltage panels and/or long cable runs.
