To test the long-term stability of PV modules, particularly with EKO’s MP-160 outdoor based test system, the I-V characteristics of multiple PV cells and modules can be measured. The MP-160 in combination with the MP-303 Load Selector provides 6 channels to measure IV curves of PV modules which can be kept at MPPT conditions with an optional load. The optional load can be a passive load, electronic load or power optimizer which is connected to the inverter and grid. In total 8 units of the MP-303 can be connected to one MP-160.
