TERRA
TERRA FIRMWARE POWER PLANT CONTROLLER
There are many reasons why the Terra Firmware plant controller is different, better and lower cost.
It’s time for a simplified experience.
Unlike our competitors, Terra Firmware doesn’t just buy an off-the-shelf piece of hardware, cobble together
hardware-specific and inflexible computer code and resell it as a renewable energy plant controller.
Our Plant Controller was designed and built from the ground up by a team of PV inverter engineers, energy
system designers and field service technicians for one purpose: to provide the ultimate in performance,
reliability and future-ready adaptability.
Our products are made in Boston, MA and are built to be rugged and reliable under any operating conditions
imaginable. All at a fraction of the cost of competitor’s offerings.

TECHNOLOGY COMPATIBILITY
Use for control and monitoring of:
• Solar PV inverters
• Wind inverters
• Battery-Based Energy Storage inverters
• VAr inverters
When used in conjunction with a BMS (Battery Management System) for Energy Storage applications
the Terra Firmware Plant Controller will strategically maintain battery state of charge according to
scheduled or predicted need.
PRIMARY CONTROL FUNCTIONS
Automatic voltage regulation
Real power curtailment
Real and reactive power ramp rate control
Frequency droop response
Scheduled power output
Reactive power control modes:
• Power factor control mode
• Reactive power control mode
• Power factor compensation mode
Voltage compensation mode
Voltage regulation mode
Low/ High Voltage ride-through (LVRT/ HVRT) control
Low/ High Frequency ride-through (LFRT/ HFRT) control
DATA MONITORING AND FAULT ANALYSIS
Calculate and report RMS real / reactive current, voltage and power values in real-time
Concentrate data from other inverters / devices on the network
Record fault data and system parameters during fault sequences
TERRA FIRMWARE POWER PLANT CONTROLLER CAPABILITIES
TERRA FIRMWARE POWER PLANT CONTROLLER FEATURES AND CAPABILITIES
The Terra Firmware Plant Controller monitors system status, collects data, and issues commands to renewable energy
power plants in a traditional SCADA architecture from the system Point of Interconnection (POI) / Point of Common
Coupling (PCC). Our Plant Controller is a perfect solution for integrating and controlling solar power, wind power,
battery energy storage, and VAR production for sites of any size in any location in the world.

TERRA FIRMWARE POWER PLANT CONTROLLER CAPABILITIES
FUTURE-PROOF CAPABILITIES RIGHT OUT OF THE BOX
For sites that require near real-time control and ultra-fast response times the Terra Firmware Plant
Controller is the perfect choice: unlike most other off-the-shelf SCADA solutions the Terra Firmware Plant
Controller has inputs for current CTs and voltage PTs built-in so no additional hardware is needed to
capture these analog signals that are critical to system control. This not only reduces overall system cost;
it greatly reduces the lag time that would normally be associated with a secondary device processing the
analog voltage and current signals- the Terra Firmware Plant Controller does it all.
Built-in uninterruptible power supply (UPS) capability via a rechargeable 24V battery provides native
LVRT capability and allows for data backup and control functionality in the event of a critical power loss
during a fault or other event.
On-board oscilloscope feature captures current / voltage waveforms at up to 1200 samples/sec (user
selectable) at the POI during a fault event or user selected trigger event saves valuable time and resources
during troubleshooting. With the Terra Firmware Plant Controller there’s no need to rent power quality
analyzers to detect and analyze faults!
Advanced Asset Management and Diagnostic algorithm observes inverter and plant parameters over time
to help determine parts of the plant that are degrading before they become larger problems.
Real and Reactive power output, inverter mode selection, ramp rates and other control functions can be
scheduled based on a simple to use 24/7/day of week internal timing calendar.
Multiple parallel analog and/ or digital current and voltage inputs allows plant monitoring and control
functionality from up to three different sources for the ultimate in adaptability to unique power system
architectures or when multiple, independent control feedbacks are needed. The Terra Firmware Plant
Controller is capable of being configured to operate in any of the following scenarios to give just a few
examples of its flexibility:
• One set of current CTs and voltage PTs from the LV or MV POI bus are wired directly to the Terra
Firmware Plant Controller.
• Two sets of current CTs from different feeders in a parallel feeder system are connected to the Terra
Firmware Plant Controller while the voltage PTs are connected to the POI.
• One set of current CTs and PTs are connected to the POI while another set of CTs is connected to an
energy storage battery bank.
• An Ethernet connection from an existing power meter or ancillary hardware component is used to link
to the Terra Firmware Plant Controller, eliminating the need for CTs and PTs altogether.
The Terra Firmware Plant Controller doubles as a Data Monitoring and Data Concentration platform
that can routinely send system status and performance data to a remote server or historian for unlimited
legacy data storage.
