EXTERNAL CONNECTIONS
This allows the user to program the external output to operate a MICROACRE PROGRAMABLE
RELAY INTERFACE. This is plugged into the RJ12 port.
Pressing the
<DATA>
button will change the external output from an UNUSED output to a:
1.
SOLAR ASSIST SIGNAL
2.
DAY NIGHT no L-S SIGNAL ( L-S = Load Shed )
Load switches on at dawn with no load shed
3.
LOAD SHED SIGNAL also known as a (Low Battery
Disconnect)
4.
SOLAR ASSIST SIGNAL V2
5.
SOLAR AST UPS CNTR1
6.
WIND TURBINE BRAKE (Contact our Support team regarding this option)
7.
DAY + L-S SIGNAL ( L-S = Load Shed )
“Day Switch”
•
Connects a load when the Panel Voltage is high enough for the MPPT to track the PV
voltage and switches off when MPPT is sleeping.
•
It also disconnects the load at the set low battery disconnect voltage and reconnects the load
at the set reconnect voltage.
8.
NIGHT + L-S SIGNAL ( L-S = Load Shed )
“Night Switch”
•
Switches a load when the MPPT is sleeping and switches off when the Panel Voltage is
high enough for the MPPT to track the PV voltage.
•
It also disconnects the load at the set low battery disconnect voltage and reconnects the load
at the set reconnect voltage.
•
Note
: The external output is
only
to be used with MICROCARE MPPT CHARGER
accessories such as the Microcare Programmable Relay.
9.1
Solar Assist signal
The
SOLAR ASSIST SIGNAL
switches the relay for 10 seconds when the MPPT switches from
BOOST to FLOAT.
9.2
Day Night Signal
If
DAY NIGHT SIGNAL
mode is selected, it switches the relay when the panel power is LOW and
stays ON until the panel reconnects.
9.3
Load Shed Disconnect
If the load shed disconnect is selected the screen on the right
appears
(by pressing
<CHARGE>
to save)
The screen changes to: LOAD DISCONNECTING @
9.3.1
Load Shed Disconnect Voltage
The user can program the Voltage at which the RELAY
operates.
This is between 10-12 volts per pack and increments in steps
of
0.1 volts. If the system is 48 volts, multiply the settings by 4.
