MPPT CONTROLLER – 20A

Street Lighting
TLM2420

MPPT charge controller can keep monitoring the solar panel’s generating power and tracking the highest voltage and current values (VI) in real time, enabling the system to charge the battery in maximum power. It’s designed to be used in off-grid solar photo-voltaic systems to coordinate operation of the solar panel, battery and load, functioning as the core control unit in off-grid photo-voltaic systems.

This product features an LCD screen which can dynamically display the operating status, operating parameters, controller logs, control parameters, etc. Users can conveniently check parameters by the keys, and modify control parameters to cater to different system requirements.
