The maximum capability of absorption (Qmin) and delivery (Qmax) of reactive power resulting from the sequence of the above measures and the measures for Q = 0 must be reported in a tabular form showing, for each level of active power output between 0 % and the maximum available discharge power, if required, between 0% and the maximum available charge power, the corresponding level of reactive power consumption (and delivery), expressed both in absolute terms and as a p.u. of the rated power of the converter in terms of cos φ The test is passed according to the conditions expressed herein - storage systems in the installations with overall power up to 11.08 kW: the value of the instantaneous power factor resulting in each of the 5 (or 10) of measurement points is equal to or less than 0.95 both in absorption mode (inductive behavior) that the supply (capacitive behavior) of the reactive power.- storage system in plants with total power greater than 11.08 kW systems: the value of the absorbed reactive power (inductive behavior) and supplied reactive power (capacitive behavior) resulting in each of the 5 (or 10) measurement points is at least equal in absolute value to 48,43% of the rated active power of the converter.The value of the maximum absorbed reactive power (inductive behavior), and supplied (capacitive behavior) recorded in each of the measurement points will be reported in a table similar to Table. 4Ba - capacitive reactive power supply follows, which refers, for example, to the case of the test at full power on a non-integrated storage system. It will then generate tables 3, for the cases of maximum inductive reactive power, maximum capacitive and the behavior with the set-point Q = 0. For each measured point is allowed a maximum deviation of reactive power ΔQ ≤ ± 5% * Sn.
