FIMER UNO-DM-3.3/4.0/4.6/5.0-TL-PLUS-Q Installations Manual

Solar inverter
UNO-DM-3.3/4.0/4.6/5.0
TL-PLUS-Q

The UNO-DM-TL-PLUS-Q single-phase inverter family,
with power ratings from 3.3 to 5.0 kW,
is the optimal solution for residential installations.

From 3.3 to 5.0 kW

String inverter - UNO-DM-3.3/4.0/4.6/5.0-TL-PLUS-Q

One size fits all

The design wraps FIMER’s quality and engineering into a light­weight and compact package thanks to technological choices
optimized for installations with different orientation.

All power ratings share the same overall volume, allowing higher
performance in a minimum space, and feature dual Maximum
Power Point Trackers.

Easy to install, fast to commission

The presence of Plug and Play connectors, both on the DC and
AC side, as well as the wireless communication, enable a simple,
fast and safe installation without the need of opening the front
cover of the inverter.
The featured easy commissioning routine removes the need for a
long configuration process, resulting in lower installation time
and costs.
Improved user experience thanks to the build in User Interface
(UI) which enables access to features such as advanced inverter
configuration settings, dynamic feed-in control and load
manager, from any WLAN enabled device (smartphone, tablet
or PC).

Smart capabilities

The embedded logging capabilities and direct transferring of the
data to Internet (via Ethernet or WLAN) allow customers to enjoy
the whole Aurora Vision remote monitoring experience.

The advanced communication interfaces (WLAN, Ethernet,
RS485) combined with an efficient Modbus (RTU/TCP)
communication protocol, Sunspec compliant, allow the inverter
to be easily integrated within any smart environment and with
third party monitoring and control systems.
A complete set of control functions with the embedded efficient
algorithm, enabling dynamic control of the feed-in (i.e. zero
injection), make the inverter suitable for worldwide applications
in compliance with regulatory norms and needs of the utilities.

Energy Viewer

This new tool allows residential customers to remotely monitor
the performance of their own solar plant and provides all
information necessary to increase energy self-reliance and
self-sufficiency.

Highlights

• Wireless access to the embedded Web User Interface

• Easy commissioning capability

• Future-proof with embedded connectivity for smart building and
smart grid integration

• Dynamic feed-in control (for instance “zero injection”)

• Remote firmware upgrade for inverter and components

• Modbus TCP/RTU Sunspec compliant

• Lifetime free of charge access to Aurora Vision
