MPP Tracking at PLA Loads
The “small” PLA loads now also have Maximum Power Point Tracking capability, even as standard.
An extensive Maximum Power Point Tracking (MPPT) function for testing photovoltaic panels can be activated. In variable sweep periods, the V/I characteristic of the panel is measured and stored. The sweep direction is selectable. The absolute maximum power found is controlled until the function is stopped or a certain minimum voltage is underrun. If the panel voltage is above the minimum voltage again, the load continues the sweep and control process.
To perform this function, firmware revision 2.1 is required for the concerning electronic load. Please contact the H&H support if you want to update your PLA load’s firmware.
