The BlueSolar series of charge controllers are some of the latest and most efficient MPPT controllers available. The BlueSolar 100-15 controller is based on a Freescale MC9S08AC32 40MHz MCU, can handle up to 100V 15A PV installation, hence then model name.  This allows up to 400W of PV on a 24V battery setup, which is pretty much for such a relatively small controller.

Also known as the nice clone, [https://www.fangpusun.com/mppt75-05-10-100-15-catalogue Fangpusun BlueSolar 100-15]

The RS232 port on the controller, when connected, outputs a continuous stream of the current status and state of the system.

Status values provided:

* Panel voltage, mV - measured direct after the screw terminal
* Panel power, W - product of Battery current x Panel voltage, there is no dedicated panel current
* Battery voltage, mV - measured on directly after the screw terminal, before the fuse
* Battery current, mA - sense resistor, delta pv and load current, panel is directly connected to battery and load output
* Load output state, ON/OFF - output switch state
* Load current, mA - sense resistor
* Yield total, kWh - accumulated overall
* Yield today, kWh - accumulated one day
* Maximum power today, W - peak power output achieved
* Yield yesterday, kWh
* Maximum power yesterday, W

Changing the settings of the controller is also possible, done via special commands outlined in the [https://www.victronenergy.com/support-and-downloads/software white paper]. They begin with a ":" and end with a new-line character.
