SINGLE PHASE HI 10/12kW | User Manual43
What this page displays:
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.
Low Power Mode<Low Batt: If selected and when battery SOC is less than the “Low Bat” value, the
self-consumption power of the inverter will be from the grid and battery simultaneously. If unselected,
the self-consumption power of the inverter will be mainly from the grid.
Low Noise Mode: Low noise mode is used to change the switching frequency of the IGBTs from 15kHz
to 20kHz, we did this because 15kHz was in the audible range still meaning that people with great hear-
ing could hear a high pitch noise when using other electrical products, the inverter interacted with it on
the AC line with electrical noise.
Disable Float Charge: A battery has three stages of charging, bulk, absorption, and oat. Once the third
stage has been reached which will be the oat charge the inverter gradually charges the battery. Some-
times, this results in the batteries being overcharged so enabling this function it will disable the third
stage in the charging cycle which is oat charge.
What you can do from this page:
Adjust battery shut down (voltage or %)
Adjust low battery warning (voltage or %)
Adjust restart (voltage or %)
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.
