Beware of the Brand
Infringement of voltalinkbattery

Recently, a severe infringement and fraud issue has caught our attention. A FAKE application with a FAKE logo, a FAKE website https://www.voltalinkbatteryinvest.com/ and even FAKE videos under the name of voltalinkbatteryare now spreading all over India, attempting to seduce people to invest money in energy storage systems by using a FAKEvoltalinkbattery logo and real voltalinkbattery products photos.

It's obvious that they are looting money by using a FAKEvoltalinkbattery brand and have seriously violated the intellectual property rights of voltalinkbattery.

voltalinkbattery shall spare no efforts and no costs to go against the violation by all means legally before more people get deceived.

Simple Setup and Excellent First Experience

Great satisfaction with my first use of voltalinkbattery inverters. I used voltalinkbattery hybrid inverters with their storage system for the first time and was pleasantly surprised by how easy it was to set them up and activate the monitoring.

Clear Monitoring and Smooth Everyday Performance

The battery works very well. The app is also easy to use and very clear. You can immediately see how much battery percentage is left, how many watts your solar panels are generating, and how much you are taking from the grid. I am very satisfied with it.
