The string optimizer (S-MPPT) is used to solve the problem of voltage mismatch caused by bypass diode damage, PID effect, shadow, different obliquity , dust and other problem.
l Tracking the string's maximum power point (MPPT) function.
l Conversion efficiency reaches 99.6%, with leading level in the industry.
l Isolate input and output to avoid strings interaction.
l Film capacitor, high reliability, long life.
l Perfect cooling design, no fans with low power consumption.
l Modular design, simple and quick installation or maintenance.
l Meet outdoor installation requirements.
l With protection for over-current, over-voltage, over-temperature state.
