Three clear routes to reach a technically valid proposal sooner.
02
AC-side retrofit
For adding a battery to an existing photovoltaic installation.
- Existing inverter validation
- Phases, metering and EMS
- Protection and final topology
03
C&I and BESS
For projects where power, autonomy, integration and floor space matter.
- Load and production profile
- Operation and critical loads
- Documented sizing
A quality difference in C&I
More storage in less floor space
In commercial buildings, industrial sites and retrofit projects, available space can limit system capacity. BattBank reduces that constraint with a high-energy-density architecture.
224 kWhwith 2 Atmoce BattBanks
0,88 m²of occupied floor space
≈44 %less floor space versus 1.56 m²
- 224 kWh in 0.88 m², compared with a conventional 215 kWh cabinet solution occupying around 1.56 m².
- Better use of technical rooms, outdoor areas and projects where every square metre matters.
- More storage capacity without expanding the project footprint.

Smart retrofit
More storage without rebuilding the whole installation
The best battery is not the one that forces everything to be replaced, but the one that can integrate with what is already there. The 7 kWh ATMOCE solution enables flexible, scalable storage upgrades.

Retrofitstorage added later
Scalableto match demand
- Enables integration with existing hybrid or grid-tied inverters to be assessed.
- Ideal for adding storage to an existing photovoltaic installation.
- Capacity can grow as consumption and customer needs evolve.
Final compatibility depends on the inverter, electrical architecture, phases, metering and configuration of each installation. Our technical team validates every project before proposing a solution.

Atmoce: technical questions frequently encountered by support
Answers based on anonymised Atmoce commissioning and after-sales patterns. The final architecture is validated for each project.
What must be confirmed for an Atmoce retrofit with third-party inverters or microinverters?
Confirm the existing system model and phase, AC diagram, power, gateway or EMS, battery, planned backup, metering point and critical loads. The architecture supported by Atmoce must also be verified; electrical coexistence does not automatically imply functional integration.
Why are CTs important in an Atmoce installation?
The system uses metering to interpret import, export and consumption. An incorrect phase, reversed direction, wrong location or a mismatch between CT and phase can cause inconsistent data and incorrect charging or discharging decisions.
What should be checked if the app shows inconsistent production or consumption?
Compare the readings with real measurements and check phases, CT direction and position, configured ratio, communication status and the installation diagram. Provide simultaneous screenshots of PV, grid, consumption, battery and SOC, not only the main screen.
How is backup verified in Atmoce?
First define which loads must be backed up and check the diagram, power and peaks, reserve SOC and backup equipment status. Then perform a controlled test following the applicable procedure and record voltage, power and events; enabling an option in the app is not enough.
Why might a backup option appear differently for an installer and an owner?
Visibility may depend on role, app version, firmware, region and plant configuration. Before assuming a fault, compare screenshots from both profiles and record the versions; support can confirm whether the function is available for that architecture.
What documentation should be sent before Atmoce commissioning?
Send the single-line diagram, models and serial numbers, firmware, phase distribution, photographs of power and communication wiring, meter or CT positions, backup loads and plant access or identification. This helps detect incompatibilities or installation errors before the session.
