About

InstaGen

Read full description

Instagen Enduser is a mobile application developed by InstaGroup Limited especially for owners of distributed PV power plants, which can absorb the operating data of PV power plantS from InstaGroup Cloud. There are more functions, such as module-level monitoring, real-time data display for both plant-level & module-level as well as daily, monthly, annual, and total energy display. Furthermore, you can easily see the alarm information with the equipment, which could assist the owner in monitoring the operation of the PV power plant, ensuring normal operation of the power plant and obtaining of the expected yield.
