Inductive & capacitive AC load banks are reactive only and must be used in combination with a resistive load bank to provide the desired load profile to test a power system. Reactive loads banks can provide either a leading power factor (Capacitive) or lagging power factor (Inductive).

Islanding effect is not allowed in the solar photovoltaic power system regarding the power quality and electrical safety, since it will cause potential threat and damage to the electrical equipments. JUNXY inverter RLC load banks are mostly used for inverter anti-islanding preventative test experiments which meets the PV & grid inverter testing requirements for islanding prevention detection, work efficiency test, overload protection test, over current protection test, power factor test, grid current harmonic test, resonance point test, and so on. PV Transformer and battery system maintenance should also be included for Grid-connected photovoltaic power plant operation and maintenance by JUNXY products solutions.
