EP Cube

by Eternalplanet Energy Co., Ltd.

Project Description

The EP Cube, an energy storage system tailored for households, aims to offer users a flexible, smart, and efficient energy management solution.
In the current market flooded with green household energy management products, the EP Cube stands out with its easy installation and personalized customization. It employs quick connectors, instead of traditional cables and wires, greatly simplifying installation and enhancing installation efficiency. By stacking battery modules, the product extends capacity and power output. Each module boasts a capacity of 3.33kWh, allowing for customizable combinations that provide five capacity options ranging from 6.6kWh to 19.9kWh. Such a design avoids unnecessary costs while meeting diverse demands of users. The system, in conjunction with its dedicated APP, enables more intelligent and flexible control in terms of status setting, real-time energy generation/storage/consumption monitoring, remote management and so on. In addition, the APP leverages future weather forecasts to enable energy storage before severe weather arrives, satisfying the power needs of special circumstances. For example, the product will seamlessly switch to backup power in the event of an outage, ensuring continuous electricity supply to the household.
For more economical and efficient energy use, the EP Cube comes with emergency backup & self-consumption PV & time-of-use modes to cater to various energy management needs. Moreover, it integrates a hybrid inverter supporting both DC and AC coupling. This effectively reduces energy loss due to solar inverter limitations, significantly enhancing energy conversion efficiency. The system also allows for connection to up to 4 MPPTs, which ensures efficient solar energy storage despite of varying environmental conditions (temperature and sunlight intensity), well meeting the demand of modern households for a green, smart and efficient energy solution.
