The voltage displayed on the Sunsynk Parity Inverter will vary depending on whether the
inverter is charging or discharging 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 efficiency. AGM batteries are very heavy as a result)
State of Charge
Bulk: Bulk charge is the first stage of a battery’s charging process where the charger
identifies 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)
Absorption: To fully charge a battery a period of charging at a relatively high voltage is
needed. This period of the charging process is called absorption. This occurs when the
charging of a battery has reached reached 80% of its capacity. The remaining charge
equals 20% approximately. It makes the charger to hold the voltage at the charger’s
Activating Shutdown causes the inverter to enter standby-mode. It does not completely
shut down the inverter. Total shutdown occurs at voltages below 19V.
NOTICE
Since the batteries are 48V the figure 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-off higher is better for the
batteries.
