Three-Phase vs Single-Phase: Which Batteria Domestica Suits Your Connection?

Your connection determines your choice

Whether you're looking for a plug-and-play system or a complete high-voltage installazione — the type of your electrical connection is the starting point. Nei Paesi Bassi, circa 70% of homes have a monofase connection (25A or 35A). New build homes and larger detached houses increasingly have a trifase connection (3x25A or 3x35A).

The distinction matters: a trifase system on a monofase connection won't work. And a monofase inverter on a trifase connection only utilises one third of the grid capacità. In this article, we explain the difference and help you make the right choice.

The difference explained

Single-phase connection

A monofase connection has one active power conductor (phase) and a neutral conductor. The maximum simultaneous power is limited to 25A × 230V = 5,750 W (or 35A × 230V = 8,050 W). Most homes nei Paesi Bassi fall into this category. Plug-and-play systems always operate on monofase.

Trifase connection

A trifase connection has three active phases and distributes power across three circuits. The maximum power is 3 × 25A × 230V = 17,250 W. This is ideal for nuclei familiari with a pompa di calore, large caricatore EV (11-22 kW) or high total consumption. New build homes receive a trifase connection as standard.

The overview below helps you quickly determine which type of system suits your connection and situation:

Batteria systems by connection type

The choice of batteria system is closely linked to your connection type and your inverter. Here are the most popular combinations:

Best choices for monofase

For a monofase connection, plug-and-play systems and smaller inverter ibridos are the logical choice. The most requested models are:

• Anker SOLIX Solarbank 2 Pro (4.8 kWh): plug & play, no installatore needed, ideal for monofase
• Anker SOLIX X1 Batteria Domestica (5 kWh): inverter ibrido included, monofase up to 6 kW
• EcoFlow Power Ocean (5 kWh): modulare system, suitable for monofase hybrid setup

Best choices for trifase

For a trifase connection, you need a trifase inverter ibrido. This distributes power evenly across all three phases, which is essential for a stable system with high simultaneous consumption. Popular options include:

• Huawei SUN2000 + LUNA 2000 (10-15 kWh): the most requested trifase combination for larger homes
• Anker SOLIX X1 (10-20 kWh, trifase version): modulare, espandibile, EPS support
• Dyness Tower T10 (10.24 kWh): compatible with multiple trifase inverters

How to check your connection type?

Your connection type is listed on your quadro elettrico report (request via Mijnnetbeheerder.nl) or is visible from the number of phase fuses in your quadro elettrico. One fuse = monofase. Three identical fuses behind a main fuse = trifase. Unsure? A installatore certificato can determine it in 5 minutes.

Choosing with a future trifase upgrade in mind

Currently on monofase but considering a trifase upgrade in the future (e.g. when purchasing a pompa di calore or large caricatore EV)? Then opt for a trifase compatible batteria that also works on monofase, so you can easily upgrade later without replacing the batteria.

Conclusion: seek expert advice

The choice between monofase and trifase is decisive for the entire configuration of your sistema di batterie domestiche. A wrong choice leads to underutilisation or technical incompatibility. Our advisers assess your quadro elettrico free of charge and provide tailored advice.
