In the far reaches of northern Mexico

In two remote regions of the Mexican state of Chihuahua, PV-powered microgrids bring electricity to a university and an agricultural ranch, neither of which are well served by the regional grid. The microgrids make use of lithium-ion batteries supplied by Growatt, alongside modules from local manufacturer SolarEver. The projects serve as an example of how products like Growatt’s off-grid inverters and energy storage solutions can bring reliable solar power to regions with limited energy access.

The mobility rEVolution: Microgrid for EV charging, hydrogen fueling, backup power
