ESSIS helps Romanian households save on energy bills
Project Background
In Romania, the uncertainty of rising electricity prices, combined with severe winter cold and the risk of power outages, has prompted more and more households to seek more stable and independent energy solutions. At the same time, modern residences have also put forward higher requirements for the appearance and overall coordination of energy storage systems. The customer aimed to build an energy storage system that could adapt to low-temperature environments, reduce electricity costs, and integrate with the architectural style of the house, thereby achieving energy independence and improving quality of life.
System Configuration
So how did we help the customer solve this problem?
We provided the customer with a customized residential energy storage system, including:
•Powerbox 5.1 (5.12kWh) energy storage battery with IP66 protection and a built-in heating function, enabling safe and efficient charging even at temperatures as low as -20°C.
•6kW hybrid inverter with IP66 protection, supporting generator connection and electric vehicle charging expansion, featuring strong system scalability.
The entire system supports outdoor installation with excellent waterproof and dustproof capabilities, easily coping with complex weather conditions such as rain and snow. Meanwhile, the battery’s built-in heating module ensures stable operation under Romania’s low winter temperatures. In terms of design, the system features a sleek appearance that blends naturally with residences, making energy storage equipment not only part of the energy system but also an element of the home environment.
Customer Value
This system helps customers effectively reduce energy bills and achieve a more economical and efficient way of electricity consumption. It operates stably in frigid environments, ensuring continuous and reliable power supply for households. Additionally, the product design integrates naturally with residential styles, enhancing quality of life while supporting the transition to green energy.
