Battery Setup
Batt
Batt Capacity
: enter the size of the battery bank connected to the
system. Series = add Voltage | Parallel = add Amp-Hours
Max A Charge
: set the max charge rate for the batteries (This also
sets PV
Battery charge rate)
Suggest 20%-30% of battery capacity for lead-acid
Max A discharge
: set max discharge for battery bank (In off-grid
mode, the battery bank will discharge 120% of this value for 10 seconds before the inverter shuts down to prevent
battery damage)
TEMPCO
: Temperature coefficient used in conjunction with the batt temp sensor to adjust optimal voltages for lead-
acid batteries
Use Batt V Charged
: displays battery charge in terms of voltage
Use Batt % Charged
: Battery voltage can be misleading for determining the % Charged. So, we use algorithms
measuring power in and out to measure a true value for % Charged. It compensates for aging batteries also.
Charge
Float V
: Set value appropriate for the batteries connected to the system
Absorption V
: Set value suitable for the batteries connected to the system
•
Absorption will stop at 2% of the capacity of the battery bank and drop to float
•
Ex: 400Ah battery would be 8A
Equalization V
: Set value appropriate for the batteries in use.
Days:
the period between equalization cycles
Hours
: period taken to equalize batteries
Note if Hours = 0 system will not equalize the batteries
Gen Charge
: uses the gen input of the system to charge the
battery bank from an attached generator.
Start V:
voltage at which system will AutoStart a connected
generator to charge the battery bank
Start percentage
:
Percent S.O.C at which system will AutoStart a corresponding generator to charge the battery bank
A
: Charge rate from the attached Generator in Amps (DC)
Size this value according to the generator size
Grid Charge
: uses Grid input to charge batteries from grid or generator
Gen Exercise Cycle (Day & Time)
: Set a weekly Gen exercise schedule. (Day of the week/Time/Duration Length)
Gen
must
have two-wire start connected to Sol-Ark. To disable the exercise, set the duration length to 0 min.
