Page 8: Safety Instructions
SAFETY INSTRUCTIONS Warning! Read all the instructions and cautions before using the PowerMon-5S device. Thornwave Labs Inc does not assume responsibility for any injury or property damage caused by improper installation, bad wiring, or use of PowerMon-5S outside of its intended purpose. The device should be installed by a professional. - Page 9 Pay attention to re-install the two washers between the shunt and the circuit board. Failure to do so will result in a short-circuit that will damage the circuit board. Thornwave Labs does not take responsibility for damage caused by removing the circuit board. Use the enclosed black wire to connect the battery negative to the left side terminal.
- Page 10 Power relay control. PowerMon-5S can drive a power relay (either mechanical or solid-state) using the RELAY output. When active (relay turned on), the RELAY terminal is internally connected to BATT- by the device. The relay should be connected between the power supply (battery positive, typically) and the RELAY terminal.
- Page 11 Live Data page will change to “Ext. Temperature”. Internal clock. PowerMon-5S keeps track of time internally. The internal clock can be set by tapping on the Device Clock tab for longer than one second. The internal date and time will be updated using the system time provided by the mobile device.
- Page 12 Battery SoC: The battery state-of-charge is displaying in percentage, from 0% to 100%. If the value displays “unset” is because the battery fuel gauge component inside the PowerMon-5S is not yet synchronized with the battery. The fuel gauge will synchronize automatically when a full charge is detected.
- Page 13 500A. It can be set lower to potentially increase the resolution of the reading. To do this it has to be set to lower than 273A. By doing this the resolution will be increased 4 times. Obviously, the maximum current PowerMon-5S can now measure is only 273A.
- Page 14 High Voltage Disconnect HVD Disconnect Threshold (V): The voltage in volts above which the power relay will disengage. HVD Connect Threshold (V): The voltage in volts below which the power relay can re-engage (after the connect filter time has passed). This must be lower than HVD Disconnect Threshold. HVD Disconnect Filter (milliseconds): The duration of time the voltage must be above the disconnect threshold for the relay to disengage.
- Page 15 Battery Fuel Gauge Battery Chemistry: The chemistry of the battery used (Lead Acid – Flooded, Lead Acid – AGM, LiFePO4, Li-Ion, Li-Poly). Battery Voltage: The battery voltage (can be the standard 12V, 24V, 48V, … or custom, in which case the number of cells in the battery can be configured).
- Page 16 The master password locks only certain functions that are critical to the correct and safe operation of the device. The manufacturer of a custom system using the PowerMon-5S battery monitor can use the master password to protect those critical areas of the configuration. The critical areas protected by the master password can be unlocked by tapping on “Master Access Unlock”...

WIRING DIAGRAM From the charging sources: • Solar charge controller To the loads • AC/DC converter • Inverter / charger Typical application with a power relay • The disconnect functions are available (relay installed) • The charging sources are connected before the relay. This is done so they cannot be disconnected from the battery during a low voltage or other disconnect events (very important for an MPPT charge controller). - Page 19 DIMENSIONS Dimensions are in mm.
