Network UPS Tools - Welcome
The primary goal of the Network UPS Tools (NUT) project is to provide support for Power Devices, such as Uninterruptible Power Supplies, Power Distribution Units and Solar Controllers.
NUT provides many control and monitoring features, with a uniform control and management interface.
More than 100 different manufacturers, and several thousands models are compatible.
This software is the combined effort of many individuals and companies.
