Next, pay special attention to the charging parameters. If one of these is set incorrectly, it throws off the whole
system and you’ll see red lines and error messages.
The equalize voltage should be the highest in value or at the very least, equal to absorb. If your batteries are
not supposed to be equalized, then set the EQ voltage equal to the absorb voltage for safety. The absorb
voltage should be followed by float, re-float, then re-bulk voltages. If one of these voltages is out of order (say
re-bulk higher than re-float), you will either not be allowed to save your changes, or the system will auto-correct
the voltages to a different value than you had set.
Protection level voltages should be set so that LBCO is the lowest voltage and HBCO (high battery cut out)
is the highest voltage by at least 1 volt from any charging value. This will ensure there are no conflicts in
the system.
Aux Terminals and Rapid Shutdown
The SkyBox has a 12-volt output and a normally open (NO) auxiliary relay. Either can be configured for AGS
or rapid shutdown. The 12-volt output and relay operate independently of each other.
Configuring the auxiliary terminal for AGS does not mean that rapid shutdown is no longer enabled. The rapid
shutdown function in the SkyBox is dependent on the connection between the auxiliary terminals 4 and 12.
(See the link to the
Quick Start Guide
on page 4 and refer to item 12 in the
Wiring
section.) When rapid
shutdown is selected as an auxiliary function, the SkyBox activates either the output or the relay when it
senses a rapid shutdown command.
Rapid Shutdown Options
You have two basic options when setting up a SkyBox to comply with the rapid shutdown requirements of the
NEC 2017: The IMO FireRaptor and the Tigo TS4-S. OutBack Power has tested both the FireRaptor and the
TS4-S successfully.
Both options work with the OutBack Rapid Shutdown Initiator (RSI) and individual modules attached to each
panel in the array. If the main power goes out, the FireRaptors or TS4-S modules lose power and shutdown
the power of the array. The SkyBox senses this loss of continuity at its rapid shutdown terminals (pins 4 and
12) and discontinues operations until the condition is cleared. Wiring diagrams and a more in-depth
explanation can be found in the
SkyBox Rapid Shutdown Application Note
.
Modbus Controls
If you would like to connect to the SkyBox using the SunSpec protocol, please contact OutBack Power Sales.
