Common reasons and fixes for why an app can't connect to an energy storage system
Problems with network communication are the most typical reason.
Most apps for energy storage systems use Wi-Fi, Ethernet, or 4G/5G connection modules. If the network isn't steady or the settings aren't right, the APP will show "offline."
The way to fix things is as follows:
Make sure the energy storage equipment is connected to the internet correctly.
Check the strength of the router's signal and the speed limit of the network.
Check to see if firewall or intranet policies block data in business and industrial projects.
For big projects like 2 MWH Energy Storage Systems or 3 MWh Energy Storage Systems, they are generally put in industrial parks or substations. These places need better network environments, and setting up communication is very important.
A strange communication gadget or data collector
Most energy storage systems have data collectors or communication gateways built in that send device data to the cloud. The APP won't be able to connect successfully if the module is turned off, broken, or has firmware that isn't working right.
Here is an idea for a solution:
Restart the communication module or the whole Energy Storage Battery System.
Look at the state of the light that shows communication.
For remote diagnosis or a firmware upgrade, get in touch with the maker.
Problems with the app version or account settings
Some people may have trouble binding their devices after they transfer accounts, upgrade their system, or change their phone.
What to do next:
Update to the most recent version of the official app
Check to see that the permissions on the account match those on the device.
Re-scan or link the serial number of the system
What should I do if the energy storage battery's capacity goes down?
"Reduced capacity" doesn't always mean the battery is broken.
A lot of people have said that the battery doesn't last as long as it used to, but this is really a natural part of how energy storage batteries wear out. After a number of charge and discharge cycles, any Energy Storage Battery System will slowly lose capacity.
This attenuation is normally balanced and handled at the system level in big systems like the 2 MWH Energy Storage System and the 3 MWh Energy Storage System. It does not affect the overall safety of the system.
How the environment in which the device is used and the method for using it affect its capacity performance
The following things will speed up the loss of capacity:
Long-term operation at high or low temperatures
Filling and filling often
Long-term high-power discharge
The battery's "available capacity" will drop quicker than the design number if the system runs under a lot of load for a long time.
Problems in calibrating the Battery Management System (BMS)
Sometimes, a drop in capacity is only a "display issue." If BMS isn't calibrated properly for a long time, the SOC (remaining charge) judgement may be off, which could make consumers think that the battery capacity has gone down.
The answers are:
Follow the manufacturer's instructions and do a full charge and discharge calibration.
Relearn battery settings from the system's backend
Technical staff did professional testing.
How can big energy storage systems deal with capacity loss?
When capacity changes happen in commercial or grid-level applications like 2 MWh Energy Storage Systems and 3 MWh Energy Storage Systems, the industry usually uses the following methods:
Modular design that allows for the replacement of a single cluster battery
Design for system-level capacity redundancy
Smart scheduling to keep one battery from being used too much
This keeps the whole Energy Storage Battery System running smoothly even if parts of the batteries lose capacity.
