Load Controller; Dusk-To-Dawn Lighting Control - BLUE SKY SB3000i Installation And Operation Manual

Blue Sky Energy – Solar Boost 3000i
2) LOAD CONTROLLER – "out" setup selector set to "Lod" (load)
The load controller can deliver up to 20 amps of output and operates as a high side switch to battery positive. Default settings are for Low Voltage
Disconnect (LVD) with ON at V
ProRemote display is present in the system. See the IPN ProRemote manual for more detail regarding amp-hour setup and control. The ON/OFF
condition must be continuously valid for 20 seconds before switching will occur. If the higher/lower setting values are reversed, i.e., ON threshold is
lower than the OFF threshold, the output control logic is inverted such that low battery voltage turns the output ON.
➢ CAUTION: 25 amp maximum over current protection for the load control output must be provided externally. If
user supplied over current protection is not provided and the load control output is short circuited the 3000i will be
damaged in a manner that voids the warranty. DO NOT use load control to directly drive ballasts, inverters, or other
highly capacitive loads as this may damage the load control output in a manner that voids the warranty. Use an
external mechanical or solid state power control relay driven by the 3000i's load control output to operate these
difficult loads.
If the load control is configured to operate based on net battery amp-hours, configure ON/OFF voltage thresholds
as well. If amp-hour from full data is not available from the IPN ProRemote, voltage based operation will resume.
ON/OFF thresholds must not be the same value or improper operation will result.
3) DUSK-TO-DAWN LIGHTING CONTROL – "out" setup selector set to "Lod" (load)
The 3000i's load control output may also be configured to provide lighting control. Variable time settings are available to turn lighting ON after Dusk
(Post-Dusk timer) and/or ON before Dawn (Pre-Dawn timer). If both timers are set to DISABLED (factory default), the lighting control feature is disabled.
If either the Post-Dusk (PSt) or Pre-Dawn (PrE) timers are set to a time value the lighting control feature is enabled. When lighting control is enabled the
Load output is controlled by both the normal LVD control function and the lighting control function such that whichever function wants the Load output
OFF prevails. Dusk or night time begins when the charge control system turns OFF which occurs when PV module current drops below 50mA at
battery voltage. Dawn or day time begins when the charge control system turns ON which occurs when PV module current rises to 100mA at just
above battery voltage. If the Post-Dusk timer was set to 1.0 hour and the Pre-Dawn timer was set to 2.0 hours, lights would turn ON at Dusk, remain
ON for one hour, and then turn OFF. Two hours before Dawn the lights would again turn ON and remain ON until Dawn. For full Dusk to Dawn
lighting set the Post-Dusk timer to 20 hours. When the 3000i first boots it does not know when Dawn is expected to occur. As a result Pre-Dawn
control will not operate for the first night. Once a night time period of 4 hours or more is detected this night time period is stored and Pre-Dawn
control will operate. Each subsequent night time period greater than 4 hours is added to a filtered average of night time so that the predicted night
time period automatically adjusts to changing seasons. To optimize battery life in lighting applications, lighting control includes a dimming feature
which may be used to operate the lights at reduced brightness in the middle of the night between when Post-Dusk and/or Pre-Dawn timers are ON.
When lighting control is enabled the dimming feature PWM's the load control output at 100Hz with the percent ON time being controlled by the PEr
(percent) setting (factory default = 0%).
➢ CAUTION: The middle of the night dimming feature is meant to be used with loads that are primarily resistive such
as directly driven LED or incandescent lighting only. DO NOT use the dimming feature with ballasts, inverters, or other
highly capacitive or inductive loads as this may damage the load control output in a manner that voids the warranty.
