The ON front panel button is used to set the SP PRO to either IDLE (SP PRO is
monitoring but providing no AC output) or ON (Inverter output is operating normally)
By default, when the battery supply is connected, the SP PRO will power up in IDLE
mode. With the Power Up Output Mode setting, this can be changed to power up in
ON mode without having to press the ON button.
The SP PRO is designed to communicate with an external computer, either directly
connected or via a communications device to a distant location.
There are two ports for this data transfer. When connecting through a modem DTR/
DCD control signals allow the modem to signal the SP PRO that a modem connection
has been established and when that connection has been dropped.
These control signals can be enabled through
Port 1 DTR/DCD and Port 2 DTR/DCD
while the speed of the data flow can be set with Port 1 Baud Rate and Port 2 Baud
Rate .
When connecting directly with a computer through the USB port or data cables the
Port 1 Baud Rate would normally be set at 57600 bps (default).
Port 1 DTR/DCD is not supported and only provided for backward
compatibility.
“Managed AC Coupled Solar” Section activates the AC coupled features within the
SP PRO including the communications link with the Selectronic Certified grid inverter.
The SP PRO Managed AC Couple Solar provides an efficient and convenient method
of adding solar that is connected via the AC Bus.
I slanding Power Limit limits the output power of all the connected compatible solar
inverters when the SP PRO is islanding or Off Grid. In a multi-phase system this
setting is per phase. For example in a three phase system an Islanding Power Limit
setting of 10kW will limit the total solar output for the system to 30kW when islanded.
This parameter is useful in Solar Hybrid systems with small battery banks and allows
the maximum amount of Solar to be installed and outputted when the system is
connected to the grid because the SP PRO will reduce the maximum solar output to a
safe level when islanded (during a grid outage).
This setting is automatically set based on the SP PRO model and battery size.
Solar Backoff Generator Minimum Power. This setting backs off the Managed AC
coupled Solar to try and maintain a minimum generator output power. This is used with
generators that have problems at low load power.
Monitoring Direction determines how the AC Source Limit Monitor operates. When
Monitoring Direction is Export, and the exported power to the grid is greater than
Trip Power Limit for the Trip Time, the SP PRO signals the managed AC coupled grid
inverters to turn off. Setting these limits to suit the requirements of the connected utility
will ensure they are never exceeded.
When
Monitoring Direction is Import, and the power drawn from the grid or
Generator is less than Trip Power Limit for the Trip Time , the SP PRO signals the
managed AC coupled grid inverters to turn off. This setting in useful in off grid systems
to maintain a minimum load on the generator or grid connected systems where the
utility requires a minimum draw from the grid.
