INTRODUCTION
Thanks for choosing I-DC48V integrated wall mounted energy storage system (ESS). This user manual introduces the product information, using guidance, safety precautions and maintenance of the system.
To ensure personal and property safety or use this product efficiently, please take your time to read and familiarize yourself with the contents of this user manual as it contains important information about the operation, servicing, troubleshooting and limitations of the system.
Note: Retain this document in a safe and accessible location for future reference. The manufacturer shall not be legally responsible for any equipment damage or personnel injury caused by incorrect installation or operation other than that is covered in this manual.
Brief introduction
The integrated energy storage system is a combination of inverter and battery, which is mainly used in household energy storage system as picture F2-2.
The combination of a PV, battery power grid, and electricity meter forms a household storage system. With this system, your family could achieve energy independent. Take your energy future into your own hands and reduce your energy costs to a minimum. The ESS system can also be used as Emergency power supply.

WORKING PRINCIPLE
To prevent the load leakage affecting the inverter, it is recommended to connect an isolation transformer outside the load output port. Isolation transformer secondary N line connected to PE.
Working Mode
According to the power grid conditions, the working state of the system can be switched automatically. There are four working modes: Storage mode, Load mode, peak cutting and valley filling mode, and off grid emergency mode.
Storage Mode
At the storage mode, the system will charge the battery prior until it is fully charged. And the stored energy can be used for emergency application.
Load Mode
Under load mode, the system will ensure the power of consumption load first to reduce the power taken from public power grid.
Peak Cutting and Valley Filling
The customer can freely set the charge and discharge time of the battery through the upper host PC of the inverter. Set the system to load mode in peak hours. And switch to storage mode at the low-price period. In this way, the difference of electricity price in peak and valley period can be reasonably utilized to bring benefits to your family. As shown in the following picture.
Off Grid Emergency
When the public power grid is cut off, the system can be used as a backup power supply.
