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).
Number of Cells: Number of cells of the battery. 12V Lead Acid batteries have 6 cells. 12V LiFePO
4
batteries have 4 cells. If you have batteries connected in series, add the number of cells in each of them.
If batteries are connected in parallel the number of series cells does not change. This is the number of
cells that contribute to the battery nominal voltage.
Total Battery Capacity: Battery capacity in Ah. If batteries are connected in parallel, add their capacities.
If batteries are connected in series the capacity does not change.
Disconnect on Battery SoC Threshold (%): The device will disconnect power (turn the relay OFF) when
the battery state of charge becomes lower than this threshold (in percentage).
Connect on Battery SoC Threshold (%): The device will re-connect power (turn the relay ON) when the
battery state of charge becomes higher than this threshold (in percentage).
Generator Control
Turn On Based on Voltage: If enabled the generator will be turned on when the battery voltage drops
under a specified threshold.
Turn On Voltage Threshold (V): The threshold in volts below which the generator will be turned
on.
Turn On Voltage Filter (milliseconds): The duration of time the voltage must be below the turn-
on threshold for the generator to be turned on.
Turn On Based on SoC: If enabled the generator will be turned on when the battery SoC (State-of-Charge)
drops under a specified threshold.
Turn On SoC Threshold (%): The threshold in percentage below which the generator will be
turned on.
Turn Off Based on Voltage: If enabled the generator will be turned off when the battery voltage increases
above a specified threshold.
Turn Off Voltage Threshold (V): The threshold in volts above which the generator will be turned
off.
