7.3.2 - ABSORPTION SETTINGS
Absorption time varies per installation according to total bank size and total PV kW.
Our maximum absorption time is 4 hours, however most installations need 2-3
hours on average. To estimate your rough absorption time, use the following formu-
la:
[(AH * DOD) / CHARGE AMPS * 0.85]
If your charge controller offers a setting such as Absorb End Amps (Outback) or sim
-
ilar that automatically transfers to float charge based on amps accepted, absorption
time should be set to 4 hours and this setting should be set to approximately 1.75%
of total bank capacity in Ah.
7.3.3 - CHARGE RATE & EQUALIZATION
Charge amps should be set up to 25% of total bank capacity in Ah. The minimum
recommended is 10%, but verify that your absorption time will not exceed 4 hours.
Equalization is not recommended for any of our products, please disable equaliza
-
tion or set to the minimum time and voltage equal to absorb. If you experience a
significant loss in capacity, please contact our technical support for further support.
7.3.4 - DEFAULT SETTINGS
When custom settings are not available, please use the following options:
7.3.5 - INVERTER SETTINGS
Low Voltage Cut Off or Low Battery Cut Out (LVCO/LBCO) will vary based on how
large your loads are and may require adjustment if your runtime is too short.
If you have a charge controller setting not listed above, you may call our technical
support at (800) 522-8191 with your charge controller’s make/model and our staff
will assist you further.
