SP PRO: The multi-mode inverter that does it all

SP PRO Firmware and SP LINK Software History

The following table shows the features added in recent versions of SP LINK and the inverter firmware.

You should normally have no need to update the firmware unless recommended by your System Integrator.
If features listed do not solve a problem you are experiencing, it is safest to leave your system alone.

We recommend System Integrators always keep the latest version of SP LINK, to ensure compatibility with our most recently manufactured inverters.

  • AC Coupling Instant Trip when Battery Voltage exceeds a Max Voltage Limit. This prevents overvoltage on fully charged Lithium batteries, which could otherwise shutdown the BMS.
  • New Current Shunt option "Direct SoC" allows a State Of Charge reading of 0-100mV from a Lithium BMS.
  • New Shutdown input causes the SP PRO to go into idle when the input is active. This is useful for a Lithium BMS to prevent shutdown of the battery bank.

SP PRO Firmware 8.00

  • SP PRO Managed AC coupling with ABB solar grid inverters. Only applicable to Selectronic Certified units available from Selectronic only.
  • Digital Output 3 is unavailable when ABB Solar is selected in a Managed AC Coupled configuration.
  • Ramp frequency for Generic AC coupling is adjustable from 50.1 to 55.2 Hz. There is a failsafe where the AC output frequency will ramp to 55.2Hz under a high battery voltage condition.
  • The AC output of the SP PRO will frequency ramp to 55.2Hz with high battery voltage, regardless of configuration, providing failsafe for unconfigured or misconfigured AC coupled systems.
  • In a Solar Hybrid (grid connected) power system, the maximum AC coupled Solar (with Managed AC Coupled Solar) is no longer limited by battery capacity. Limits based on the SP PRO model still apply.
  • Added “Islanding Power Limit” to include both ABB solar and KACO grid inverters. In a managed AC coupled system, the maximum power output of the AC coupled solar is reduced to suit the Inverter model and battery capacity when the system is Islanded (grid has failed) or when configured as Off Grid (no grid available).
  • SP PRO firmware requires SP LINK 8.0 or higher.

SP LINK Software 8.0

  • Screen size and position is saved between SP LINK sessions. Screen position of Help file improved.
  • Add new baud rate setting of 115,200 baud for Communication Ports.
  • Add ABB Solar option to AC coupled port.
  • Updated Site Configuration Wizard to include ABB Solar.
  • Change Site Configuration Wizard to remove battery capacity limit for AC coupled solar (Managed AC Coupled Solar)  in Solar Hybrid systems.
  • Automatically set "Islanding Power limit" based on the battery size, brand of AC Coupled inverter (ABB or Kaco) and SP PRO model.
  • Add Zero Percent Output (remote off) for ABB communications.
  • Disable Econo mode setting when Generic AC coupling is selected.
  • Display the RS485 device address for KACO or ABB Solar grid inverters in Data View > Technical Data screen.

SP PRO Firmware 7.09

  • Powador control loops optimised to provide greater charging control in both Hybrid and Off Grid systems.
  • Improved response time of Generic Inverter frequency control: Now responds in under 1 second if AC source is disconnected and frequency ramping is required.
  • Fixed: When only Phase 1 supply connected to Phase 1 of a multiphase phase system, all phases will operate fans correctly.
  • For phase charging current regulation, SoC Shunt current is now not used by each phase. This affects three phase installs as per IN0016 Rev 7 and higher, using 600A shunt. Please check charge current settings after updating firmware. Installs as per IN0016 Rev 6 and lower, using 400A shunt, are not affected.
  • SP PRO firmware requires SP LINK 7.7 or higher.
