Description
05.01 UDC on break V 1 DC link voltage at which the charger brake applies
05.02 UDC on charge V 2 DC link voltage at which the charger starts to charge
battery
05.03 UDC off charge V 2 DC link voltage at which the charger starts to
discharge battery
05.04 Curr. Limit char A 1 Charging current limit
05.05 Curr. Limit dos A 1 Charging current limit
05.06 Umax battery V 1 Max battery voltage
05.07 Umin battery V 1 Min battery voltage
05.08 Tmax battery °C 1 Max battery temperature
05.09 Block run A 1 Charger lockout
0 → charging 1 → charger is not operating
05.10 Un V 1 Nominal battery voltage
05.11 Delta Ibat A 1 In order to protect against excessive discharge of the
connected batteries, the inverter monitors the voltage
and the current consumed.
When the voltage value drops below the value
specified in parameter 5.7 "Umin battery" and the
obtainable current value is lower than the value
specified in parameter 5.11 "Delta Ibat", the inverter
will stop further discharging the battery.
In order to recharge them, the inverter will first try to
get energy from a renewable energy source
(photovoltaic panels, wind generator), but if the
amount of generated electricity is too small,
depending on the operating mode:
a. on-grid: for charging the battery itinverter will draw
energy from the power grid,
b. off-grid: inverter will block the possibility of further
discharge of the connected battery,
0 - battery protection disabled.
