The Simarine SC503 combines a 500A battery-current shunt with tank and temperature inputs for a compatible PICO monitoring system. It measures battery voltage and current while adding sensor connections, reducing the number of separate modules needed for a monitoring installation.
The shunt can monitor high-current consumers such as inverters, thrusters or windlasses, or measure output from charging equipment including solar and shore-power chargers, within its electrical limits.

- Dedicated JST temperature-sensor connection.
- 500A continuous current and 600A peak rating.
