The ABB UNO DM 5kW is a single-phase solar inverter from the Swiss technology company ABB that’s perfect for residential installations. 

If you’ve been paying any attention to the world of solar energy or engineering, you’ll likely have heard about ABB; this group of companies is divided into five major divisions: electrification products, robotics and motion, industrial automation and power grids, serving customers in utilities, industry, transport and infrastructure. 

In this article, we are going to examine the ABB UNO DM 5 kW Plus single-phase inverter as an option for providing your house with solar power. With a near-countless array of modules available on the market, it’s important to take a step back and assess exactly what you’re purchasing. 

We’re curious to see what ABB has put into this unit, so without any further delay, let’s take a closer look.

What is the ABB UNO DM 5 kW Solar Inverter?

The UNO DM 5 kW is a single-phase solar inverter manufactured by ABB. It features dual MPPTs offering a maximum efficiency of 97.0% to 97.4%. This solar inverter weighs 15kg, rather light considering its capacity.

The UNO employs Maximum Power Point Tracking (MPPT) technology that adjusts the current and voltage of the solar panels to get the most efficient flow of energy from them. It has two such controllers, enabling MPPT for two strings of solar panels, which opens up many possibilities for optimisation.

ABB is one of the best solar brands in the world, with manufacturing and R&D sites in Finland, India, and Italy. With revenues eclipsing 34.31 billion USD and almost 135 thousand employees, they have more than enough resources to develop the kind of top-shelf engineering products you would expect from the Swiss.

Powered by Fimer, ABB UNO DM solar inverters can provide up to 320 kW of power capacity. This is more suited to commercial solar projects, such as solar farms with hundreds of solar panels set up in remote locations.

What is the ABB UNO DM 5 kW Solar Inverter’s Output Capacity?

The single-phase and three-phase string ABB UNO DM solar inverters will provide you with 1.2 kW to 120 kW output power. This is more than enough energy for homes and small businesses. The average household rarely needs more than 5 kW of power from a solar system to comfortably power everything.

An output of 5 kW makes this single-phase inverter a reliable solution for properties with reasonable electricity demands. The UNO does not include solar panels and assuming you have these already provides you with simple control options that will help you optimise your energy generation process.

What is the ABB UNO DM 5 kW Solar Inverter’s Efficiency?

The UNO DM series features a transformerless operation with an incredible 98% efficiency potential. To put this in perspective, residential solar inverter efficiency standards generally lie between 95% to 98%. As such, this hybrid inverter is perfectly capable of optimising your solar panel system efficiency. 

The EU weighted efficiency for the UNO-DM-TL-PLUS-Q 5.0kW is 97%, and it has high efficiency of 97.4%. Thanks to its wide input voltage range, ABB’s UNO is ideal for low-power installations. 

How Many MPP Trackers does the ABB UNO DM 5 kW Solar Inverter have?

ABB’s UNO DM 5 kW solar inverter contains two MPP Trackers. Maximum Power Point Tracking (MPPT) technology adjusts the current and voltage of the solar panels to get the most expedient flow of energy from them. 

The UNO has two such controllers, so MPPT can be performed for two strings of solar panels, which opens up many possibilities for optimisation.

Does the ABB UNO DM 5 kW inverter come with an Internal DC Circuit Breaker?

Certainly! The ABB UNO DM 5 kW inverter features an internal DC circuit breaker, which provides a barrier between Direct Current (DC) and Alternating Current (AC). This short circuit protection enables your solar system to function normally even when the alternating current unit fails. 

ABB UNO DM 5 kW Key Features

Here are the main features of the UNO DM 5 kW inverter:

  • Plug-and-play Functionality

This is an easy-to-install inverter because all the connections are clearly laid out and you won’t have to open up the inverter at any point. This is especially helpful given that some inverters require additional electrical components at specific values to work as intended. 

Thus is hardly ideal if you don’t know your circuit elements, and even if you do, it’s unnecessarily complicated for a basic setup. As a result, the UNO DM 5 kW inverter will save you a lot of time in the installation process.

  • Maximum Power Point Tracking (MPPT) Technology

MPPT adjusts the current and voltage of the solar panels to get the most efficient flow of energy from them. The UNO has two such controllers, so MPPT can be carried out on two strings of solar panels, which grants you sizeable scope for customing your system.

  • Reverse Polarity Protection 

The UNO has excellent safety features, including reverse polarity protection from a limited current source. Simply put, there are electrical circuits known as current sources, and there’s also an infinite current source.

An infinite current source does not actually exist in practice. Still, it can be approached by some circuits, which will damage the inverter if allowed to source current into the output of the inverter. There’s no real reason you would want to do this, but it’s useful to know all the same.

  • Dynamic feed-in Control

In some Australian states, you have to pay time-dependent feed-in tariffs and not the fixed rates that are currently available. This is where controlling the amount of energy being delivered to the grid is particularly beneficial; when the feed-in tariff is at its lowest, that is when the least amount of power should be injected into the grid. 

This inverter can even cease power feed into the grid altogether. This interface is so straightforward and user-friendly that anyone can optimise the system, even a beginner!

  • Over-the-air Firmware Upgrades

The UNO has a controller that isn’t hard-wired but is constructed from what’s called ‘programmable logic.’ Essentially, the firmware (the controller circuitry) can be modified or replaced by new and improved coding.

The firmware can be updated over-the-air using Wi-Fi, so the user doesn’t need to open up the inverter to manually update the controller. This makes the inverter future-proof because you can revamp the device’s controller if necessary.

  • String-sizing Tool

To form a string inverter solar panel, strings would need to be connected to the UNO. The string sizing tool can help you determine the best size for your solar panel strings to get the greatest benefit from your system. 

All you need to do is specify the design location and maximum and minimum temperatures that are provided with design options. This makes the UNO your first component in, potentially, a very productive solar system.

  • Aura Vision Remote Monitoring

The operating conditions need to be analysed to achieve optimum output levels from the system, and the controller can be configured to the right values with this information. It would be very difficult, however, to attach measuring instruments to the inverter at regular intervals to get meaningful measurements.

Aurora Vision provides the solar system owner with real-time information about how much energy is being converted from solar energy to electrical power. This is cloud-based, meaning you can access this information online from anywhere as long as you have internet access.

If you, as the system owner, want the very best performance over a sustained period, this software will let you store your results digitally for further analysis.

  • On-board Microprocessor

One peek at the inside of the UNO, and you will know straight away that this is no basic inverter; it’s capable of doing everything you would need to control the operation of the inverter.

For those of us lacking coding skills, there are presets available for a standard setup, but to really use this device to its fullest extent, it’s worth learning some code.

An example of how this would be helpful is when one string of solar panels is covered by shade while another is unobscured. You can get the energy to come from the shadeless string with no shade and, in doing so, prevent the shaded portion from negatively affecting the overall flow of energy. Not bad for an off-the-shelf inverter, right?

What is the ABB UNO DM 5 kW Solar Inverter’s Warranty?

ABB single-phase inverters come with a standard 10-year manufacturer’s warranty for Australian customers. The warranty period starts on the day you install the solar inverter or six months after the manufactured date, whichever occurs first.

ABB will honour all warranty claims for string inverters installed before Fimer acquired the company.

Is the ABB UNO DM 5 kW Solar Inverter Reliable? Is the Solar Inverter Safe?

The ABB UNO DM 5 kW can withstand heavy snow and wind loads up to 2,000 psi. ABB is a top solar manufacturer and has ensured that the UNO is one of the solar industry’s safest and most reliable modules. Their solar inverters are constructed from top-quality materials and can endure the harshest conditions. 

The company has state-of-the-art testing laboratories and has acquired certifications such as the Standards for Environmental Management System, Quality Management System, and International Standards for Occupational Health & Safety. 

Is the ABB UNO DM 5 kW Solar Inverter CEC-approved?

Like other ABB inverters, the Clean Energy Council (CEC) has approved the UNO solar inverters. This endorsement makes these inverters a great option for the Small-scale Renewable Energy Scheme.

Can you Retrofit a Battery to the ABB UNO DM 5 kW Solar Inverter?

You can attach a battery storage system to ABB UNO DM 5 kW solar inverters. However, be sure to use a compatible battery solution. In this manner, you’ll soon have an all-inclusive solar power solution that fits seamlessly into your existing setup.
