Good charge controller ideal for 10 gauge DC cables. Actually no options, no history, NO LOADING! You can change the date and time and the battery type. Don't think that you can change the temperature from C to F. Very cheap hanging arms feeling. only the bracket hangs on brackets at the top. In general, the case is comfortable and durable. The LCD display is bright and clear. However, it is not clear which software can also be used for additional functions such as settings and history, or which remote counters can be configured with it. It says it uses RS-485 and the Modbus protocol. It would be nice to find these parameters. There is also no phone number or website to answer these questions.
