PICO Standard set for you if you want to monitor 1 main battery or battery bank, up to 4 starter or auxiliary batteries, and up to 6 tanks or temperatures.
The SC303 shunt, which is included in this set, allows for a continuous current up to 300 amps. It has 2 resistance and 2 voltage inputs, and 1 socket for a temperature sensor.
Additionally, the ST107 tank level and voltage module provides the system with 4 resistance and 3 voltage inputs. Its main purpose is to measure water, fuel, or other liquid levels, but you can also use it to measure voltage or temperature.
One of this module’s special features is a built-in, programmable alarm signal relay, which you can configure to output a signal of 1 amp if an alarm is triggered.
