8.5.2 Battery control mode (MPPT 6000-M only)
NOTICE!
– The state of charge (SOC) mode or voltage control mode can be selected for lead-acid or
lead-gel/AGM battery types.
–
Voltage control is the predefined fixed mode for Li-Ion and NiCd battery types.
– The State of charge (SOC) control mode activates calculation of the state of charge
of the battery. This calculated SOC value is shown in the status display and the
measurements, see
Ä Chapter 7.3 ‘Status display’ on page 53.
– In the State of charge (SOC) control mode, the calculated state of charge controls
execution of the following functions:
– Deep discharge protection
– Excess energy control
– Generator control
See
Ä Chapter 9 ‘Control functions via AUX 1/2/3 (MPPT 6000-M only)’ on page 103.
– This also controls activation of the following charge modes:
– Boost charging
– Equalisation charging
See
Ä Chapter 8.5.8 ‘Charge voltages’ on page 66.
– In the voltage control mode, the actual battery voltage controls execution of the
following functions:
– Deep discharge protection
– Excess energy control
– Generator control
See
Ä Chapter 9 ‘Control functions via AUX 1/2/3 (MPPT 6000-M only)’ on page 103.
– The actual battery voltage also controls activation of the following charge modes:
– Boost charging
– Equalisation charging
See
Ä Chapter 8.5.8 ‘Charge voltages’ on page 66.
– Using the state of charge (SOC) control mode only makes sense when all battery charge
and discharge currents can be measured by the MPPT 6000-M. Additional PA HS400
current sensors are required for measuring the discharge currents. Additional external PA
HS400 current sensors are also required for measuring charge currents that do not flow
through the MPPT 6000-M or through MPPT 6000-S devices in the master/slave network.
– No additional current sensors are required when using the voltage control mode.
– If the discharge depth is to be taken into consideration for adjusting the upper charge
voltage U1 when charging NiCd batteries then the discharge current must be measured by
external PA HS400 current sensors. The necessary sensors must be activated via the
Sensor member list menu item.
– All devices to be used for calculating the total battery current must be specified in the
Sensor member list menu item. The total of all currents selected here is used for
calculating the state of charge and is displayed in the Total charge/discharge
current of battery field of the status display, see
Ä Chapter 7.3 ‘Status display’
on page 53.
