The ECO-E64WX is a compact hybrid storage system (ESS) designed to be combined with solar energy (PV) and suitable for residential to light commercial applications. The system offers a storage capacity of approximately 64.5 kWh and is designed according to the "all-in-one" principle: battery, inverter/hybrid inverter, HVAC (cooling/ventilation), fire suppression system (FSS), and energy/battery management system (EMS/BMS) are integrated into a single cabinet.
The system is intended for scenarios such as self-consumption of solar power, peak power management (peak shaving), backup power or combinations thereof.

Features & Benefits
Compact footprint : With a floor space of approximately 0.96 m², this unit is relatively small and therefore suitable for places with limited space.
Hybrid PV + ESS integration : Designed to be paired with a hybrid inverter and suitable for self-consumption with solar power, peak shaving or backup.
High DoD & Good Cycle Life : With ≥ 95% DoD and ≥ 5,500 cycles, the system offers reasonable capability for utilizing the stored energy.
Modular expansion : With parallel connection you can expand the capacity or power as desired without needing a completely new system.
Safety and reliability : With IP55 housing, air cooling, good ventilation (cell temperature difference ≤ 6 °C) and aerosol fire protection.
Application scenarios
Commercial or light industrial installations with solar energy where storage of approximately 60-70 kWh is required.
Buildings where self-consumption of solar power is pursued and where peak power management or load shifting is desired.
Backup or emergency power supply on a smaller scale, for example for offices, small businesses, or in combination with charging station systems.
Locations with limited space or where a compact, integrated solution is required.
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.
