How does a lithium battery energy storage system work?
A lithium battery energy storage system is an advanced electricity storage device that operates together with a solar power plant and a hybrid inverter. The system stores instantaneous surplus electricity generated by the sun (which would otherwise be fed into the grid or curtailed) and allows it to be used later, when the sun isn’t shining and household energy demand increases.
How does “IGLU Kadlu LV” work in practice together with a solar power plant?
Kasdienis sistemos veikimo principas yra paprastas ir orientuotas į maksimalų pačių pagamintos energijos suvartojimą. Dienos metu, kai saulės elektrinė generuoja piką, o namuose nieko nėra, „IGLU Kadlu LV“ automatiškai įsikrauna. Vakare, prasidėjus intensyviam buitinių prietaisų, šilumos siurblio ar elektromobilio įkrovimo stotelės naudojimui, namas naudoja sukauptą energiją iš baterijos, užuot pirkęs brangią elektros energiją iš tinklo.
„IGLU Kadlu LV“ sistema yra siūloma lanksčiomis konfigūracijomis, kurios prasideda nuo 10,24 kWh bazinio bloko ir gali būti išplėstos iki 15,36 kWh, 20,48 kWh, 25,60 kWh bei 30,72 kWh. Su 5,12 kW vardine įkrovimo bei iškrovimo galia ši sistema lengvai susidoroja su kasdieniais buitiniais iššūkiais.
Due to the integrated popular communication interfaces (CAN, RS485), it is important to align the technical parameters with your existing hybrid inverter before installing the system. A properly designed home energy system not only helps reduce electricity bills but also provides reliable backup power in the event of a grid outage (emergency).
Which technical criteria are the most important to pay attention to?
When choosing a home energy storage system, it’s not enough to look only at price and total capacity. Here are the key parameters that determine the system’s safety and longevity:
- Battery chemistry: IGLU TECH savo energijos kaupikliuose naudoja ličio geležies fosfato (LiFePO4) elementus iš lyderiaujančio gamintojo CATL. Ši sudėtis šiuo metu yra pripažinta saugiausia stacionariems namų kaupikliams, nes pasižymi itin aukštu terminiu stabilumu ir neturi užsidegimo rizikos, būdingos kitų tipų ličio jonų baterijoms.
- Operating temperature: The operating ambient temperature range is clearly specified in the technical documents. The system can discharge at temperatures from -20 °C to +55 °C, but battery charging safely occurs strictly from 0 °C to +45 °C temperature. Also, under safety requirements, the unit must not be operated in environments where the temperature exceeds +40 °C. Therefore, in Lithuania’s climate, the battery is recommended to be installed in an insulated technical room or garage that maintains above-freezing temperatures and is protected from direct sunlight and moisture.
- Depth of Discharge (DoD) and cycles: The manufacturer’s declared 6,000-cycle count is achieved under laboratory test conditions. In everyday use, to maximize cell lifespan, the recommended depth of discharge (DoD) is 80 %. This ensures the battery will serve reliably for many years without significant capacity loss.
Why choose a modular and expandable system?
Modular architecture is a major advantage that lets you optimize initial investments. If your current electricity consumption is moderate, you can start with a basic 10.24 kWh module.
If in the future you decide to buy an electric vehicle, install a more powerful heat pump, or simply increase your solar plant’s capacity, you won’t need to purchase an entirely new system. “IGLU Kadlu LV” allows you to connect up to 5 modules in parallel, increasing the total system capacity and flexibly adapting to the growing needs of your family or small business.
Why choose IGLU TECH battery storage systems?

Todėl prieš įsigyjant įrangą, visuomet verta pasikonsultuoti su specialistais, kurie padės įvertinti suderinamumą su inverteriu bei parinks tinkamiausią montavimo vietą.
Frequently Asked Questions
Can this system be connected to an existing solar power plant?
Yes, but your current inverter must support low-voltage (LV) battery connectivity. Before purchasing, you should verify that the inverter’s technical specifications are compatible with “Kadlu LV.”
Can IGLU Kadlu LV be installed in an unheated garage?
The battery enclosure features a high protection rating, but charging is safe only at positive temperatures (from 0 °C to +45 °C). If the garage temperature drops below zero in winter, charging will be automatically halted to protect the cells. Therefore, it’s best to choose minimally heated or insulated rooms.
How many years will this energy storage system last?
Under standard use (one charge and discharge cycle per day), a 6,000-cycle lifespan ensures reliable operation for about 15–20 years, after which the battery retains most of its original capacity.
