SINGLE PHASE HI 3.6/5kW | User Manual44
What this page displays:
Lithium Mode: This is BMS protocol. Please reference the document(Approved Battery).
Shutdown 10%: It indicates the inverter will shutdown if the SOC is below this value.
Low Batt 20%: It indicates the inverter will alarm if the SOC below this value.
Restart 40%: Battery voltage at 40% AC output will resume.
What you can do from this page:
Adjust battery shut down (voltage or %)
Adjust low battery warning (voltage or %)
Adjust restart (voltage or %)
PLEASE NOTE
Activating Shutdown causes the inverter to enter standby-mode. It does not entirely shut down the
inverter. Total shutdown occurs at voltages below 19V.
The voltage displayed on the Sunsynk Parity Inverter will vary depending on whether the inverter is charging
or discharging the batteries.
Since the batteries are 48V, the gure on the left is x4:
Fully Charged 50.54V (Discharge Mode)
Fully Charged 58.50V (Charge Mode)
75% Charged 49.60V (Discharge Mode)
75% Charged 54.80V (Charge Mode)
25% Charged 48.00V (Discharge Mode)
25% Charged 50.80V (Charge Mode)
Completely Discharged 47.50V
Setting the cut-o higher is better for the batteries.
The batteries recommended for use with the Sunsynk systems are AGM Lead Acid or Lithium Battery Banks.
(‘AGM’ means Absorbed Glass Matt construction that allows the electrolyte to be suspended new the plate’s
active material. In theory, this enhances both the discharge and recharging eciency. AGM batteries are very
heavy as a result).
State of Charge
Bulk: The bulk charge is the rst stage of a battery’s charging process, where the charger identies the
battery and its needs and then applies a high voltage to do the bulk of the charging. It involves about 80% of
the recharge. The properly sized charger will give the battery as much current as it will accept up to charger
capacity (25% of battery capacity in Amp hours).
