The ECO-E100/120WP is an all-in-one energy storage system (ESS) from Elecnova, designed for commercial or industrial applications. It combines battery storage, energy management system (BMS/EMS), inverter/PCS, and cooling/enclosure in a single integrated unit.
The storage capacity is around 120 kWh, with a power output of approximately 100 kW. It follows the same format as other ECO series models, such as the ECO-E100WX or ECO-E101WX.
DC side (battery):
-
Cell type: LFP (Lithium-Iron-Phosphate)
-
System voltage: high voltage DC (comparable to ~700-950 Vdc on other 100 kW class models)
-
Energy capacity: ~120 kWh (given the “120” in the type designation)
-
Depth of discharge (DoD): high, often ~95% at 25 °C.
-
Cycle life: several thousand cycles (typically ≥ 5,000)
AC side (mains):
-
Nominal AC power: ~100 kW
-
Mains voltage: 400 V AC / 3P + N + PE (like other models in the same series)
-
Harmonic distortion (THDi): low (≤ 3%)
-
Power factor: widely applicable, possible -1 to +1
General & mechanical:
-
Enclosure: “all-in-one” cabinet, integrated BMS/EMS, thermal management (air cooling or other)
-
Protection degree: probably IP55 or similar (like other models)
-
Cooling: Forced air cooling (probably)
-
Temperature range: about –25 °C to about +55 °C when comparable with other models
-
Weight and dimensions: estimated to be in the same range as other ~100 kW/100–120 kWh models (e.g. several thousand kg, footprint ~1–2 m²)
Features
-
Fully Integrated System : The “all-in-one” design integrates battery, inverter/PCS, BMS/EMS and cooling/protection into a single unit, making installation easier.
-
Suitable for C&I applications : With ~100 kW of power and ~120 kWh of storage capacity, it is suitable for peak-shaving, load shifting, renewable energy integration, and potentially backup applications.
-
Modular design & expandability : Multiple units may be able to operate in parallel for increased capacity/power, depending on manufacturer support.
-
Grid compatibility : Low harmonic distortion, good power factor and integration with commercial/industrial grids.
The integrated EMS automatically optimizes consumption, storage, and grid load. In the event of a power outage, the system switches to backup power within ≤10 ms.
With a built-in EMS (Energy Management System), support for peak shaving, and flexible charge and discharge settings, energy balance is automatically adjusted to consumption, grid status, and storage.
With an IP66 enclosure, silent passive cooling, and real-time monitoring via app or WiFi, the inverter offers reliability, ease of use, and minimal maintenance requirements.
- Businesses may need to employ various types of legal pages on their websites or mobile apps. Some, like Privacy Policies, are required by law, while others, such as a Terms and Conditions agreement (T&C), are not. Regardless of legal demands, you may find that your company needs one or more legal pages for compliance and optimal operation.
- In this article, we will go over the most common legal pages, walk you through a summary of what each requires, and explain why you may need it. In addition, you'll find a sample template for each type of legal page so you can quickly get started writing your own.
