Off-grid power supply with battery storage systems | TESVOLT AG
Battery storage systems provide green power. While renewable power generators are often the lowest-cost alternative to diesel and CHP plants, they do have one major disadvantage: if there is no wind, or during darkness, wind power and solar generators are unable to provide electricity. This is where battery storage systems offer a simple solution.
