Charge Controller-MPPT CONTROLLER – 20A
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.

Features
With an all-new wireless remote control design, a hand-held device can be used to modify controller parameters and read system information
Adopts the MPPT solar charging technology, with a max. solar panel open-circuit voltage Voc ≤ 55V and max. solar panel power Pm ≤ 260W
Features load boost constant-current output, able to directly power a maximum of 18 light bulbs in series, with a max. load power Pled ≤ 60 W.
Boasts a load triple-stage brightness adjustment and morning on design, with an operating duration adjustable from 0 to 15 hours and a power settable from 0 to 100%.
Features a system status log function, able to record a maximum of 7 days of system status, comprehensively and effectively monitoring the system's conditions.
Data communication adopts a multi-time two-way handshake protocol and a data compression algorithm, realizing precise and fast data transmission.
Features an intelligent power mode that can extend the battery life to its top limit by adjusting the load power automatically according to the remaining battery capacity.
True constant current rather than current-limiting control ensures smooth and stable output current, effectively reducing LED light attenuation and extending LED service life.
