Hey, How can we help you?

AlphaESS home batteries are maintenance-free. The internet connection allows the system's software to receive regular updates.

No. The AlphaESS product needs an Internet connection (over wired Ethernet or your home Wi-Fi) to receive software updates and to communicate with the AlphaCloud for energy monitoring. A reliable connection is required to provide new product features over time. While the AlphaESS system can continue to operate with its most recent settings if the Internet connection is temporarily lost, it is not recommended to install it in a location without Internet access.

For all AlphaESS hybrid energy storage system, you can connect solar panels directly to it (= DC coupling).

All AlphaESS home batteries can be connected to an existing PV system. We call this an AC coupling. An AlphaESS system is completely independent of your existing solar panel system and can therefore be installed at any time.

Yes, you can. When connecting, 3-phase meters are used to ensure that the required power of the battery is compensated on the the 3 phases.

Here's an example:

Two consumers each need 500 Watt at a certain moment and are connected to phase 1 and phase 2, respectively. The battery system is connected to phase 3, which currently has no energy demand. The AlphaESS system then measures how much electricity is needed in total over the 3 phases at that moment (in this case 1000 Watt). This electricity is made available on phase 3 because the home battery is connected to that phase.

As there is no consumption on phase 3 at that moment, the 1,000 Watt on phase 3 is injected into the electricity grid. At the same time, the 500 Watts needed by the users on phase 1 and phase 2 are drawn from the grid. The same amount of electricity that the users need is therefore injected on phase 3 (1,000 Watts) and drawn on phase 1 (500 Watts) and phase 2 (500 Watts). In this case, the electricity meter is stopped, so there is no additional electricity cost.

Yes, you can easily connect them in a house where there is a three-phase PV inverter.

The power of the inverter is expressed in kW while the storage capacity of the battery is expressed in kWh.

A battery must always have some capacity reserved for recharging. This is essential to initiate the chemical reaction during charging. The depth to which a battery can be discharged depends on the chemistry in the battery, and to ensure a good battery life, it is generally recommended not to go to the limit. For example, a SMILE B3 battery module can be discharged up to 96% deep, which is considered a very deep discharge level.

LFP stands for Lithium Iron Phosphate, which refers to the chemical composition of the cathode in a battery cell. Charging or discharging a battery is essentially an electrochemical process. AlphaESS only uses LFP cells which are known for their thermal stability, technical excellence and outstanding safety. Additionally, these cells are cobalt-free, further enhancing their environmental sustainability and safety profile.
