The PV negative, battery negative and load negative is common.
1.3 Accessories Instructions
1. Remote Temperature Sensor (Model: RTS300R10K5.08A)
Acquisition of battery temperature for undertaking
temperature compensation of control parameters, the
standard length of the cable is 3m (length can be
customized). The RTS300R10K5.08A connects to the RTS
port (10
th
) on the controller.
NOTE
：
Unplug the RTS, the temperature of battery will be set to
a fixed value 25
℃
.
2. USB to RS-485 Converter (Model: CC-USB-RS485-150U-3.81)
The USB to RS-485 converter is used to monitor each
controller on the network using Solar Station PC
software and update the firmware. The length of cable
is 1.5m. The CC-USB-RS485-150U-3.81 connects to
the MC1.5-5.08-2L port (8
th
) on the controller.

1.4 Maximum Power Point Tracking Technology
Due to the nonlinear characteristics of solar array, there is a maximum energy
output point (Max Power Point) on its curve. Traditional controllers, with switch
charging technology and PWM charging technology, can
‘t charge the battery at
the maximum power point, so can
‘t harvest the maximum energy available
from PV array, but the solar charge controller with Maximum Power Point
Tracking (MPPT) Technology can lock on the point to harvest the maximum
energy and deliver it to the battery.
The MPPT algorithm of our company continuously compares and adjusts the
operating points to attempt to locate the maximum power point of the array.
The tracking process is fully automatic and does not need user adjustment.
As the Figure 1-2, the curve is the characteristic curve of the array, the MPPT
