M-ELV wall battery
7 kWh wall battery for regular homes.
A compact, expandable battery that can be installed alongside your existing solar panels. FlexxWatt first assesses whether storage suits your consumption and which capacity and power fit.

* The Dutch ATMOCE page states 7 kWh; the English ATMOCE page states 8 kWh. We confirm the supplied version in your quotation.
The residential BattBank combines one to three MS-16K-U modules with the dedicated residential Stack Control Unit cap & base kit MS-SCU-RES-U. It bridges the M-ELV wall battery and the commercial (C&I) BattBank: one product family, not an improvised combination of two batteries. Suitable for larger homes and small businesses.

7 kWh wall battery for regular homes.
MS-16K-U + MS-SCU-RES-U, 1–3 modules per stack, for larger homes and small businesses.
Separate commercial configuration for larger sites.

The effect depends on your consumption, generation, connection and energy contract. Savings are not guaranteed, so we calculate your situation first.
Solar power stored during the day is used in the evening and at night instead of being exported.
AC-coupled: according to ATMOCE suitable alongside existing inverters and third-party solar panels.
Modular design. Start with what fits now and expand as consumption grows, for example with an EV or heat pump.
Follow generation, consumption and battery status in ATMOCE Cloud and the ATMOZEN app.

The M-ELV is wall or floor mounted and operates at a battery voltage below 30 V. According to ATMOCE, one version suits both single-phase and three-phase connections.

ATMOCE offers a backup solution in which the battery takes over within about 10 ms during a power cut. This requires additional components, such as an ATMOCE M-Gateway and an M-Backup unit, and an adapted installation in your consumer unit.

For smaller commercial premises with solar panels the M-ELV can be a suitable solution. The ATMOCE BattBank is intended for larger power and capacity needs. Business requests go through personal advice.
We review your consumption, generation, connection and contract.
Capacity and power determined separately for your situation.
