SZ10-TA5 and Solar MPPT


SZ10-DM-TA5 is an integrated solar light controller which composed of two main modules, solar MPPT and TA5 controller.These two modules are connected via RS485 interface, and as a whole it communicates with base station wirelessly. SZ10-DM-TA5 controller is specially developed for control and management of solar lighting.


  1. Product Description

The waterproof MPPT is a constant current control module, and it integrates Solar Maximum Power Point Tracking charging management, LED boost constant current drive, remote networking communication and other functions in one. It is suitable for lead-acid batteries, lithium batteries, gel batteries, etc.

The TA5 controller is an important part of the solar lamp control system. Its core chip adopts the self-developed ZigBee wireless communication module. It can communicate with gateway & network server so as to realize the functions of lamp on/off control, dimming, current and voltage collection, etc.

MPPT and TA5 are connected via RS485 interface. With professional hardware and software design, the integrated SZ10-DM-TA5 has the advantages of high reliability, high efficiency, high precision, energy saving, powerful functionalities, simple installation, easy maintenance, etc. And makes it a high-performance product in control and management of solar lighting.
