Introduction
Product Overview
The SP PRO Sine Wave Interactive Inverter Charger is designed specifically for either solar hybrid (grid
support / grid feed) or Off-Grid (no grid available) operation.
With Powerchain capability, the SP PRO can be configured as either a single-phase power system with up to
four SP PROs or a three-phase system with up to twelve SP PROs (four per phase). A split-phase with up to
eight SP PROs is also possible. With all SP PROs in a Powerchain system operating in perfect harmony, the
power system is configured, controlled and monitored as one.
As a battery-based inverter, charger and system controller all in the one product, each SP PRO has
configurable power limits suitable for many solar hybrid applications.
(SPMC480-AU – SPMC481-AU – SPMC482-AU – SPLC1200 – SPLC1202 models only).
With its in-built generator controller, the SP PRO is also the ideal choice for all Off-Grid installations or solar
hybrid systems with generator back up.
The SP PRO is compatible with virtually any DC renewable charging source (such as a DC solar controller).
AC renewable sources (such as solar inverters) are also compatible with the SP PRO when used in a solar
hybrid system.
For Off-Grid systems or solar hybrid systems requiring export limiting, the Selectronic Managed AC Coupling is
used. Its advanced features include the precise control of the AS/NZS 4777.2:2020 compliant, Selectronic
Certified (SCERT) solar inverter. Please note that any active export power comes from the AS/NZS
4777.2:2020 compliant, SCERT solar inverter and that the SP PRO does not export active power to the grid, as
per the requirements of AS/NZS 4777.2:2020 appendix M.
Solar Hybrid Support and Grid Feed Systems
Solar Hybrid is only applicable to AS/NZS 4777.2:2020 compliant SP PRO models
(SPMC480-AU – SPMC481-AU – SPMC482-AU – SPLC1200 – SPLC1202).
In solar hybrid, the renewable energy can be directed to power the AC Load, recharge the battery bank or,
when AC Coupling to AS/NZS 4777.2:2020 compliant solar inverters, export power from these AC-Coupled
solar inverters to the grid. The direction and priority of the energy flow can be varied depending on the time of
day, battery SoC or Load demands, allowing the maximum use of the renewable energy (such as PV solar) and
stored battery energy to supply site loads to take advantage of variable electricity tariffs. A solar hybrid system
will also allow the user to only use grid electricity when they choose.
Please note that any active export power comes from the AS/NZS 4777.2:2020 compliant solar
inverters and that the SP PRO does not export active power to the grid. In the Australian market, the
SP PRO is not certified as a solar inverter but a stand-alone inverter with grid input.
By using the optional Grid Fail / Generator Backup kit (005268), the SP PRO can be configured to
automatically start and stop a generator during a prolonged power outage. When the generator is running, the
SP PRO will use the generator to power the site Load plus use any additional generator capacity to charge the
batteries.
