Features

• Steca Solsum F. The Steca Solsum F-Line continues the huge success of one of the most used SHS controllers. The circuit board is completely electronically protected and with the LED user interface it is easy to check the battery state of charge at any time. Large terminals guarantee a simple connection of solar panels, battery and load. The Steca Solsum F works on PWM as a low loss series controller. Voltage regulation Automatic detection of voltage PWM control Multistage charging technology Current compensated load disconnection Automatic load reconnection Temperature compensation Common positive grounding or negative grounding on one terminal Monthly maintenance charge. Displays. Multifunction LED display Multi-coloured LED 4 LEDs show operating states ∼ for operation, state of charge, fault messages. Electronic protection functions. Overcharge protection Deep discharge protection Reverse polarity protection of module (≤36 V),load and battery Automatic electronic fuse Short circuit protection of load and module Overvoltage protection at module input Open circuit protection without battery Reverse current protection at night Overtemperature and overload protection Load disconnection on battery overvoltage
