MATE3s System Display and Controller
The OutBack Power MATE3s System Display and Controller is the premier interface for managing and monitoring OutBack Power energy systems. An evolution of the trusted MATE3, the “s” model features a faster processor, improved screen readability, and updated firmware designed to meet strict utility grid interconnection standards (UL 1741 SA).
It serves as the central command center for your solar setup, allowing you to program inverters and charge controllers, manage generator starting, and monitor system health remotely via the OpticsRE cloud platform.
Why Choose the Outback Power MATE3s
The MATE3s is essential for modern grid-interactive systems. It is the only controller capable of programming OutBack’s advanced grid-support inverters (like the Radian and FXR series) to comply with new utility requirements such as Rule 21 and HECO. Beyond compliance, it offers a superior user experience with a “Wizard” configuration tool that makes complex system setup quick and error-free.
Frequently Asked Questions
Q1: What is the difference between MATE3 and MATE3s?
The MATE3s (white case) is the upgraded version of the discontinued MATE3 (black case). The “s” model has a faster processor, better memory, and is required for newer grid standards (UL 1741 SA) and newer inverter models like the FXR and Radian series.
Q2: Does it require internet to work?
No. The MATE3s works perfectly as a local controller without an internet connection. However, connecting it to the internet unlocks OpticsRE, which provides powerful remote monitoring and control capabilities at no extra cost.
Q3: Can I use this with older OutBack inverters?
Yes. The MATE3s is backward compatible with most legacy OutBack products, including the FX, VFX, and MX60 series, though some advanced features may not be available on older units.
Q4: How do I mount it?
The MATE3s comes with a mounting bracket that allows it to be surface-mounted on a wall. It is not designed to be flush-mounted inside a wall cutout like the older MATE2.
Q5: Does it come with the HUB?
No. The MATE3s is the controller only. To connect multiple devices (like an inverter and a charge controller), you will need an OutBack HUB4 or HUB10.3 communication manager.
