Photovoltaic system power production

The dataset contains data related to the photovoltaic (PV) system installed at Poznan Supercomputing and Networking Center used to power the servers in one of the server rooms. The data come from a 1-month measurement period taken between 03.09.2019-03.10.2019. The PV system consists of 80 PV panels with 20kW peak power. Servers are directly connected to inverters so that they can be supplied directly by the power grid, PV system in the case of sufficient generation or by batteries (75kWh) if energy production is too low. Switching between power sources can be controlled by the user, however, if batteries are discharged below 60%, servers immediately switch to the power grid to extend battery life. During the measurements, only part of the servers was attached to the PV system responsible for ~1kW power usage.
