The cell-string optimisers are highly integrated DC-DC converters perform maximum power point tracking deep inside the PV module.
Maxim Integrated Products' cell-string optimiser technology allows photovoltaic panels to harvest more energy, while also simplifying design complexity for solar installation projects.
The cell-string optimisers are highly integrated DC-DC converters that replace the bypass diode and perform maximum power point tracking (MPPT) deep inside the PV module. By replacing each diode with a MPPT device, the on-off response to performance mismatch is eliminated; every cell-string contributes maximum power without interfering with the power production capability of others. This enhanced degree of flexibility leads to increased energy production; eliminating collateral performance loss due to module mismatch, degradation, soiling, localised shading and row shading loss mechanisms.

Based on the company's industry leading power semiconductor technology, Maxim's cell-string optimiser is the first integrated power IC to perform MPPT and first to be embedded within the PV module.
