Depth of discharge
Depth of discharge
50%
EPS depth of discharge
80%
Select “3. Depth of discharge” and press “OK” to enter the menu for setting the depth of
discharge. Press the “Up” and “Down” keys to change the depth of discharge in both normal
operating mode and in EPS mode depending on the type of batteries used. Press “OK” to move
to the next digit and then confirm the setting; wait for “OK” to appear on the display.
Batteries using lithium-ion technology usually use a depth of 80%, while lead-acid batteries
use a depth of 50%. This is necessary to preserve the life of the batteries.
The depth of discharge indicates the percentage of the battery level actually used; for example,
a depth of 80% will allow cycles between 20% and 100% of the battery charge level.
A different depth of discharge value can also be set for standard operation and EPS operation.
For example, you can set a depth of 50% and an EPS depth of 80%. In this case, when the grid
connection is present, the 3000SP storage inverter will not draw energy from the batteries if
the charge level is below 50%. In the event of a power failure, the 3000SP storage inverter will
operate in EPS mode (if this was previously set) and will remain in discharge mode until the
battery charge level drops to 20%.
4)
Maximum charge current (A)
Select “4. Maximum charge current (A)” and press “OK” to enter the menu for setting the
maximum charge current. Press the “Up” and “Down” keys to change the value of the maximum
charge current. Press “OK” to move to the next digit and then confirm the setting; wait for “OK”
to appear on the display.
When setting this parameter for Pylontech batteries, refer to the table in section 6.2; for
different battery models, refer to the relative datasheet.
5)
Overvoltage threshold
Select “5. Overvoltage threshold” and press “OK” to enter the menu for setting the overvoltage
protection voltage. Press the “Up” and “Down” keys to change the value of the overvoltage
protection voltage. Press “OK” to move to the next digit and then confirm the setting; wait for
“OK” to appear on the display.
When setting this parameter for Pylontech batteries, refer to the table in section 6.2; for
different battery models, refer to the relative datasheet.
6)
Max charge threshold (V)
Select “6. Min Discharge Voltage (V)” and press “OK” to enter the menu for setting the
minimum discharge voltage. Press the “Up” and “Down” keys to change the value of the
minimum discharge voltage. Press “OK” to move to the next digit and then confirm the setting;
wait for “OK” to appear on the display.
