2G (GPRS)10A MPPT Solar Charge Controller 12V 24V

The DM120-U controller can record the operating status of the whole system, including operating days, over-dischargings, full-chargings, etc. And besides, it can also keep a record of battery voltage changes in a week, enabling the user to have a clear understanding of the system and conduct better analysis on it. The user needs to use the remote control (CU-ALL) to read the system's operating status, and when the reading is successfully done, the parameters will be recorded in the remote control.

1. What's the protocol controller used?
     Local GPRS/2G celluar provided by local sim card.

2. What is the process?
    Client provides sim card to us for development<>sample testing<>mass production.

3. What's the max light power controller can support?
There are four controllers from 60w to 200w, pls check below parameter of them:

Module Battery volatage Max light power Max panel power Max charge current
DM60-U 12v 60w 130w 10A
DM120-U 12v/24v 60w/120w 130w/260w 10A
DM160-U 12v/24v 80w/120w 200w/400w 15A
DM200-U 12v/24v 100w/200w 260w/520w 20A

4. Where should be light controllers installed?
  The controller is of IP68 protection level, so it can be installed both inside or outside the light with the antenna outside to get good signal.

5. How should I cofigure light controllers network in order to establish server connection?
  There is no need for any configuration. Once the controllers are installed they start the communication and establish connection with central server software automatically.
