Items covered by the table above are not provided by SoliTek and have to be acquired by the installer.

ADDITIONAL EQUIPMENT “BYPASS FUNCTIONALITY” To optimize the inverter’s backup feature, prioritize a “bypass” setup during installation. Employ disconnectors or circuit breakers to seamlessly switch between the Back-up’ andStraight-through’ lines. This configuration allows for swift disconnection of the backup power in case of maintenance or malfunctions, enabling a direct connection to the grid for your backup loads. This bypass arrangement streamlines maintenance processes and offers a dependable alternative power source when required.

The installation of the SoliTek NOVA battery system consists of the following steps:

STACKING

SoliTek NOVA battery system is assembled in a stack. All battery packs are identical, so their order in a stack is irrelevant. The connectors between the packs are bolt-less, i.e. they require no additional mechanical connectors or tighteners to secure the battery packs together.
Stacking process will be done in following steps:

Step 1: Lay down the baseplate in the chosen location for installation, so that the connector is facing up.

Step 2:

Then stack all battery packs, one by one, on top of the baseplate and on each other. Battery pack connectors and dedicated metallic fixation points will guide you in the stacking process. The metallic fixation points also serve the purpose of grounding system casing. On the connector side, you will have to push down so that proper contact is ensured. If the battery packs are properly stacked, the gap in between them should be uniform. Each battery pack will have two fixation holes on the back that can be used to fix the battery pack to the wall. They should be used to fix the stack to the wall

Step 3:

ensuring that no part of the stack can be laterally moved by external forces. Once all the battery packs are stacked on the baseplate, simply stack the BCB on top.

BATTERY INSTALLATION
Step 4: If there is moisture on the floor or the floor is uneven, we recommend (optional) using lifting legs to prevent battery from corrosion or falling.
To install lifting legs simply screw them up to designed place on baseplate (refer to image below).
Lifting legs have to be acquired by installer. Lifting legs thread size is M10. Select length according to installation.

GROUNDING THE BATTERY BOX

To ground a SoliTek NOVA battery system, you must prepare the grounding cable. It is recommended to use at least 6mm2 – 12 AWG cross-section copper cables.

Step 1: Fix one end of the cable to the grounding circuit. Step 2: On the other end, install an M5 ring lug. Step 3: Once the cable is ready, screw it to batteries grounding point.

The cable should be connected to the grounding circuit before being connected to the grounding terminal on the NOVA Control Box.

6.1

DESCRIPTION

Nova battery is a unique residential battery with a built-in Energy Management System (EMS) powered by Artificial Intelligence.
The target of the EMS is controlling de battery energy flow to optimize it (reduce electricity billing keeping safety back-up). In order to do it, SoliTek NOVA battery is gathering continuously solar power generation, electricity consumption meteorological information of the house. Historical data is stored and processed with Artificial Intelligence in Solitek cloud (Europe), learning household consumption habits and predicting power generation via meteo.
Artificial Intelligence EMS is updating every 4 hours the best charging/discharging strategy of NOVA’s energy for the householder.
EMS monitoring and control is done via SoliTek View. Thus, it’s needed to correctly configure NOVA EMS according to next chapter.

6.2

CONFIGURATION

Before starting operation with SoliTek View app, it’s needed to set up correctly the Battery Control Box and register our new NOVA battery system in SoliTek webservice.

BATTERY CONTROL BOX SETUP

Step 1: Switch on the battery
After NOVA battery system is correctly installed, push the ON/OFF button. Illuminating Solitek logo will indicate that battery is turned on.

Step 2: Wifi network configuration
Take a device that can connect to WiFi, and connect to the Inion network. The password for the network is scadacmms.
Once connected, open web browser and enter 192.168.4.1 into search, then you will be prompted with a network selection. Took a screenshot of web interface, there will be logger id which will be relevant during webservice setup. Select the WiFi network that you want the battery to connect to, and type in its password, if applicable. Afterwards, click `save’.

This should terminate your connection to the `Inion’ network and conclude the WiFi setup.

CHECK INVERTER SETTINGS

Once NOVA battery system is ready, user have to register it in SoliTek webservice.
SoliTek NOVA can be controlled through what is called Solitek View – a web service that lets you look at the data of both your solar plant and your NOVA battery system in real time, and make specific adjustments to the control of your energy system.
The webservice can be accessed either though the SoliTek View mobile app (found in both the Google Play Store and the Apple App Store), or simply though the solitekview.eu website.
After the installation, your SoliTek NOVA energy system is ready to be connected to your personal account. To do this, you must create an account on the SoliTek View platform. You will be guided through this procedure on the platform.
After creating an account, log into it. Once you are in the platform, add your energy system to your account. To do so, click the plug/socket icon on the bottom left of the screen.

Add device icon

After clicking it, you will be met with a code entry window. Type in the logger id from screenshot which has been made in previous steps.

Once the code is entered, you will be prompted to enter additional info:
Part 1: SoliTek view asset configuration Select the Inverter’ device, SoliTek’ manufacturer and the respective inverter that you have from the drop-down list. Then, enter the communication ID (if this is your first device, and no specific instructions were left to you by the installer, you can leave the default value, which is `1′).

Part 2: SoliTek View asset configuration
After you add this device, the next window asks if you want to add more devices, and to check the RS-485 communication data. If this is a regular installation of a single SoliTek NOVA system, no changes need to be made. If your installation is more customized, you will be notified of these settings by the installer.
Simply click Next’, then on the pop-up confirmation, clickConfirm’.
Part 3: SoliTek View asset configuration
In the following screen, select the location of the installation, and give your plant a name.

Part 4: SoliTek View plant configuration
After clicking next, you will be met with a connection test. Wait for it to confirm that your system has connected, and then click `Finish’.
That concludes the SoliTek View setup, and you will be able to see your plant and all the data from that point onward. It should take up to 5 minutes for the data graph to be drawn, but you will be able to see real-time data immediately.

We suggest naming the plant by your full name.
