## What is Su?

Traditional inverters emit indoor air pollution, a health risk, particularly for older people who reside in the home. It produces obnoxious odours, gasses, and that pollute the indoor air. The lead acid battery has high-intensity fumes of lead, which can cause long-term diseases in people as lead fumes go straight into the blood. It also ends up in landfills which causes land pollution. The hanging wires and terminals can be hazardous to the safety of the house's children and animals.


For the homes and offices, we have created a small ESS solution which can be installed in homes and offices. These ESS have an inbuilt Lithium battery and a small unit that can be placed in one corner. We have made an app which can show the voltage range coming from the grid and has the feature of protecting the home from a low and high voltage as it shifts to battery mode case of low and high voltage, which the company programs. This can be seen on the app as this app shows the real-time data for the user.
It helps the consumer see the load percentage being used when the power cut happens, and the user can increase his backup time by reducing the load.
Also, it shows in the app in case of overload and gives visual and audio alarms, and the user can reduce the load, and it gets normal in case of overload shut down. The user can reset the ESS through the phone screen itself.
The user can switch on and off the load through the app screen to save power on the battery mode.
The user can set the reserve mode of the battery, which helps to increase the battery life in an emergency. The backup can be increased when the ESS is shut down in low battery mode.
It provides visual and audio signals in case of overload, which helps the user to select the right load.
This app shows the flow of energy, whether being charged or discharged, and the load wattage and battery percentage and the user will get an obvious idea about the charging and discharging concept.
Different models work on the same app, and the product model and capacity are shown once the user scans through the app.
