Powerful LiFePO4 Solar Storage With 5.12 kWh

If operators of a solar system want to use as much of the self-generated electricity as possible themselves or bridge phases without sufficient electricity production, the Voltsmile Classic V10 LiFePO4 storage systems are ideal. They have a high storage capacity, are cycle-resistant and durable.

A three-person household in a single-family home in Germany requires an average of 9.6 kWh per day. Two Voltsmile Classic V10 (2 x 5.12 kWh), which are now available from GreenAkku.de at a price of 1,299 euros (including 0 per cent VAT plus shipping costs), cover the daily requirement even if your own solar system does not produce any electricity at all.For this installation, GreenAkku.de offers a closed wall cabinet for two Classic V10 modules for just 136 euros.

Alternatively, tower mounting is possible using plug-in brackets. GreenAkku.de offers these in pairs for 24 euros. This means that several modules can be stacked safely and neatly in no time at all. Installing additional modules in a suitable rack is even more convenient. Each module takes up three height units (3U). With the necessary, customised cable sets for power transmission and communication, even beginners can install the modules reliably in all these scenarios.

Just like the Voltsmile V5 power storage unit (with 2.4 kWh), the Voltsmile Classic V10 is also characterised by fully concealed plug and cable connections. This means that it can be installed safely and attractively not only in utility rooms, but also in rooms used for other purposes such as hallways or attics. Compatibility with all standard inverters offers flexibility for existing systems.

Thanks to lithium iron phosphate technology (LiFePO4), the Voltsmile power storage units achieve a high efficiency of over 95 per cent. They also prove to be very cycle-resistant and durable, even with regular deep discharges.

Voltsmile specifies a service life of at least 15 years, provides a ten-year guarantee and promises at least 6,000 charging cycles. The integrated BMS (battery management system) ensures optimum utilisation of the storage capacity, and the modules can be controlled via RS485, RS232 and CAN.

Charging current and discharging current are designed for 100 A. The nominal voltage is 51.2 V, the operating voltage range is between 46.4 V and 57.6 V, the nominal capacity is 100 Ah. The IEC62619 certification (for stationary lithium-ion storage systems) ensures that the performance has been independently tested and that they fulfil current safety and reliability expectations.
