End-to-end integration
- SigenStor for residential and small commercial projects.
- SigenStack for modular C&I storage.
- Gateway, backup, metering and control within the ecosystem.
- Published cases from 9 kWh to around 500 kWh.
TECHNICAL COMPARISON
Sigenergy vs Atmoce: how to choose storage
Technical comparison for installers and engineering companies. There is no universal winner: the best option depends on the existing installation, goal, power, backup and growth strategy.
The main difference lies in the architecture
Sigenergy stands out for an integrated ecosystem combining hybrid inverter, battery, Gateway, EMS and residential or C&I solutions. Atmoce offers particular flexibility with microinverters, AC-coupled retrofit and modular M-ELV storage.
Flexibility and AC retrofit
- Microinverters and residential storage.
- AC coupling to preserve existing equipment.
- M-ELV for modular C&I configurations.
- Published cases of 96.48 kWh and 112 kWh.
Quick decision matrix
Scenario
Sigenergy
Atmoce
New integrated installation
Well suited to a complete ecosystem with centralised control.
Suitable when microinverters and modularity are priorities.
Retrofit with an existing inverter
Possible depending on architecture, metering and compatibility.
Particularly attractive through AC coupling.
High-power C&I project
SigenStack has published references in the hundreds of kWh.
M-ELV must be sized using power, capacity and BOS.
Data that actually drives the decision
- Hourly or 15-minute load and production curves.
- Power per phase, peaks, starting currents and critical loads.
- Goal: self-consumption, peak shaving, backup or microgrid.
- Existing equipment, metering point and single-line diagram.
- Space, environment, maintenance and future expansion.
Compare both solutions using your project data
We prepare a preliminary architecture and identify assumptions that still require validation.
