Figure 4.5. Equalize time-out charging profile
The charging profile in figure 4-5 above, shows an
Equalize Time-out event. The time-out timer begins
as soon as battery voltage exceeds the Absorption
voltage set-point. If there is insufficient charging
current or system loads are too large, the battery
voltage may not reach the Equalize set-point. To
avoid battery damage, The Equalize Time-out safety
feature prevents high battery voltage for extended
periods of time.
4.2 Load Control Information
The primary purpose of the load control function is
to disconnect system loads when the battery has
discharged to a low state of charge and reconnect
system loads when the battery is sufficiently
recharged. System loads may be lights, pumps,
motors, DC appliances, and other electronic devices.
The total current draw of all loads must not exceed the
ProStar 15 or 30 amp maximum load rating.
CAUTION: Do not wire an AC inverter of any
size to the load terminals of the ProStar -
damage to the load control circuit may result. Wire
inverters directly to the battery or battery bank.
Current Compensation:
All LVD and LVR set-points are current compensated.
Under load, the battery voltage will sag in proportion
to the current draw of the load. A short-term large
load could cause a premature LVD without the current
compensation feature. Current compensation begins
at 3 Amps of load draw. LVD and LVR set-points are
adjusted lower per the following table:
System voltage
Current Compensation
12 Volt -20 mV per amp of load
24 Volt -40 mV per amp of load
