Input and Output Settings
The inverter contains 4 digital inputs, 4 relay outputs, 2 analogue inputs (excluding 120 V models) and 3 digital
outputs, and these form the heart of the flexibility and sophistication of the SP PROs interface with the outside
world.
With these controls you can monitor when various set points are reached, switch on appliances when certain
criteria are met, protect the generator from damage due to low oil pressure, schedule a watering system to
switch on and off and many other functions.
Maximum voltage to any input or output; 60 VDC. See SP PRO specifications for full details.
Digital Inputs in a Powerchain Systems. Only the digital inputs on the System Manager inverter L1 are
enabled. The state of a digital input on L1 automatically sets the digital inputs on all other phases.
Digital Outputs in a Powerchain Systems. Most of the digital outputs can be enabled individually for each
of the phase managers as shown in the applicable setting.
Low Batt Shutdown Override Input function is also known as the “Just Go” control.
In case of emergency, even if the batteries would normally be considered too flat to
safely run the inverter, activating this input will force the inverter to run, until there
is insufficient battery power left to maintain the load. This is considered essential if,
say, phones or a fire pump MUST be operated.
Normal/Alternate AC Input Power Selector. When a second AC Source with a
different capacity to the primary AC Source (Normal), is available to the system, use
this setting to set the input that you wish to use to select the alternate power level.
The alternate source power level is configured in Alternative AC Source Power back
in the AC Input section. When Alternate is selected, Solar Hybrid Control Priority
schedules are overridden and no longer apply.
Inhibit Export Input. In some circumstances you may wish to prevent the SP PRO
from exporting excess energy to the AC Source such as when the grid has failed
and you have connected a diesel generator into the system. Used in conjunction
with the Normal/Alternate AC Input you can switch to a different power level and
know that the SP PRO will not try to export power to the motor generator .
Shutdown Input , when active, will turn off the inverter section of the SP PRO and prevent any charging or
discharging of the battery bank. Driving this input from the warning output of a Battery Management Systems
(BMS) will provide a failsafe shutdown of the inverter. For Off Grid systems with auto start generators, the
generator will start whilst this input is active and restore power to the site.
When the SP PRO is integrated with a managed battery (e.g. BYD), and there is a serious BMS
fault within the battery system, the SP PRO will shut down as if this input was activated.
Shutdown Level selects the level at which the Shutdown Input is active
