Installation Day: What to Expect When Installing a Livoltek Battery

It’s the morning of the day scheduled for the installation of a Livoltek battery. You’re a little anxious—which is normal. Are they skilled? Will they damage the walls? Will they take hours? Will your house be left in a mess? So you don’t have to search for the answers yourself, let us show you exactly how a Livoltek installation day goes, step by step, so you know what to expect.

Before the team arrives

Your certified Livoltek installer has contacted you beforehand, and you’ve agreed on the date and time for the installation. Before they arrive, here are a few simple things you can prepare in advance to ensure everything goes as smoothly as possible:That’s all for now. And, as you can see, you don’t have to move out of your home, and you don’t have to prepare as if for a construction site.

Access to the electrical panel. Make sure the area around the panel is clear, free of furniture or other obstacles. The installer will need to work there, so access is essential.
Battery location. You’ve already decided where to mount the battery (wall or floor). The area must be accessible and at least 30 cm away from any other object or adjacent wall.
Working internet. The Livoltek battery connects to your Wi-Fi network for monitoring. Make sure you have your network password handy.
Access to the fuse box. The installer will need to temporarily turn off the power for connections.

The team arrives

The Livoltek-certified installer (possibly with an assistant) arrives at the scheduled time. They bring:The first thing they do is check your existing system. They look at the photovoltaic inverter, the electrical panel, your meter, and how the cables are routed. Not because there’s anything wrong, but to confirm what they already knew from the previous technical visit and that nothing has changed since then.

Physical Installation

If you chose wall mounting—the most common option, by the way—the installer will follow a few steps:

1. Measure and mark the position on the wall

Use a tape measure and a spirit level to ensure everything is perfectly straight.
Mark the points where the mounting screws will go.

2. Drill the holes and mount the bracket

Use a drill to make holes at the marked points.
Insert the expansion anchors.
Secure the metal bracket to the wall with screws.

3. Install the battery

Lift the battery (it’s quite heavy) and secure it to the bracket
Check that the four mounting tabs are locked securely into the bracket
Screw the inverter onto the battery
Secure the inverter to the wall for maximum stability

Throughout this process, there is no excessive dust, no loud noise, and no damage to the finishes. There are only 5 holes in the wall, plus two for the inverter, in an area that will be covered by the bracket and battery, and the inverter, respectively.

The “mysterious” part – current clamps (CTs)

Now comes the part that raises the most questions: installing current clamps, known by the technical term CT (Current Transformer).

What exactly are these clamps?

Imagine a magnetic ring that is placed around the power cable, without cutting it or modifying it in any way. It simply surrounds it. This ring “senses” how much energy is passing through the cable and sends this information to the Livoltek battery.

Why are they necessary?

The CT clamps are the eyes and ears of your system. They constantly tell the battery how much energy is being produced, how much the house is consuming, and how much is being fed into the grid (when applicable). Based on this real-time information, the battery automatically decides:

To charge itself with the solar surplus.
To supply energy to the house when the sun is no longer sufficient.
To start or stop feeding energy into the grid depending on the current parameters.

How to Install

Step 1. Identifying the Cables. The installer identifies the cable coming from the solar inverter and the cable going to the electrical grid in your electrical panel. They are already there; nothing new is added.
Step 2. Opening the CT clamps. The CT clamps open just like a large paperclip. They have a hinge on one side and a latch on the other.
Step 3. Attaching to the cable. The installer opens the CT clamp, places it around the cable (WITHOUT cutting it, WITHOUT disconnecting it), closes it until it clicks, and checks that the arrow on the clamp is facing the correct direction (toward the inverter).
Step 4. Connecting to the Livoltek battery. Each CT clamp has a thin cable that connects to the battery’s communication port. The installer runs these cables neatly along the walls or through conduits to the battery.

What changes are made to the electrical panel?

Here’s the pleasant surprise: the changes are absolutely minimal or even nonexistent. If you already have a modern, organized panel, then:If the panel is older or more cluttered, the installer may recommend organizing the cables for easier access and possibly clearly labeling the circuits (if they aren’t already). Even in the most “complicated” case, we’re certainly not talking about rebuilding the electrical panel. It’s just a matter of precision work and smart connections—and certainly nothing to tear down and rebuild.

The smart meter (optional). The alternative to CT

If you’ve opted for the Livoltek smart meter instead of CT clamps, the process is even simpler: The advantages in this case are even more precise measurements and the ability to manage consumption by zone.

Install the smart meter next to the battery or in the panel
Connect it to a selected circuit
It communicates directly with the battery via cable

Electrical Connections

With the battery mounted on the wall and the CT clamps installed, the main connections follow:

1. Cable to the electrical grid (GRID)

A special cable runs from the battery and connects to the electrical panel.
Here, the battery receives power from the grid (if applicable) and supplies power to the house.

2. Cable to critical circuits (EPS – Emergency Power Supply)

Optional, if you requested the backup function.
A separate circuit for critical loads (refrigerator, boiler, essential outlets).
In the event of a power outage, these loads continue to operate.

3. Connection to the batteries

If you have a single 5 kWh module, it is already integrated.
If you ordered 10 kWh (2 modules) or more, the installer connects the modules to each other using dedicated cables.

4. Grounding cable (PE)

Essential for safety.
It connects to the home’s grounding system relatively easily, because the inverter and the photovoltaic panel system in the compliant installation are already connected to the grounding system as well. Since the installation is located near the inverter, there is easy access to the same grounding cable.

All these connections are made using professional terminals and continuity checks.

Configuration and commissioning

Once we’ve reached this point, the physical setup is complete. Now comes the “magic,” and the system comes to life. The installer starts the system in a precise sequence:

Start the sequence.

Turn on the electrical grid.
Turn on the battery.
Connect the loads.
Configure the Wi-Fi dongle.

2. Connecting to the MyLivoltek app

The installer scans the barcodes on the battery.
Connects the system to your Wi-Fi network.
Configures the app on your phone.
Shows you the interface and main functions.

3. Final checks

The installer checks in the app to ensure that:

The battery is recognized correctly.
The CT clamps are transmitting correct data (showing solar production and household consumption).
The battery is charging or discharging according to the settings.
All LED indicators on the battery are functioning normally.

4. Custom settings

Together with you, the installer configures:

Your preferred operating mode (maximum self-consumption, backup, charging from the grid at night).
The minimum reserve level in the battery (for example, 20% for emergencies).
The notifications you want to receive in the app.

Your training

The installer won’t leave you alone with a new system. They will explain how to use the MyLovoltek app (how to view real-time battery status, check solar production, home consumption, and stored energy, how to change the operating mode, and where to find history and statistics), what each LED means, how to manually turn the system on and off (if necessary), and where the emergency button is located. You’ll also receive the system documentation and contact information for technical support.

Most importantly: they’ll also explain that the system is monitored 24/7 from Timișoara. If any anomaly occurs, we—the Livoltek team—will see it and contact the installer to resolve it.

With a quick tidy-up and packing of the tools, packaging, and documents, the installation process is practically complete. What remains are the installed devices, the mobile app, and… the benefits of using your new Livoltek battery system. You’ll know it’s working by the hum of the battery, but if you didn’t install it right next to your nightstand to disturb your sleep, then you have nothing to worry about. And from now on, instead of feeding cheap energy back into the grid, you’re storing it for yourself.
