PV systems and energy storage systems. • Dual MPPT per optimizer - Ampt String Optimizers put maximum power point tracking on each of its two input strings of PV modules. This mitigates or eliminates mismatch losses to deliver more energy under changing environmental and system conditions over the lifetime of the power plant.

Input Criteria In the figures that follow, the number of modules connected in series is representative only. Follow Ampt’s design guidelines to determine the number of modules for each input. Acceptable Input Configurations It is common for inputs A and B to have the same number of modules (i.e. A = B). However, if the number of modules between inputs is different, then input A can have one more module than input B (i.e.
National Electrical Code (ANSI/NFPA 70); Canadian Electrical Code, Part I; or the applicable standards, codes, and regulations for your region. The output current limit of the Ampt String Optimizer eliminates the need for the 1.25 multiplication factor for over-sun conditions when calculating ampacity. The 1.25 multiplier for continuous use is still required.
Inter-row Shading Wiring Example When inter-row shading is expected, the best practice is to wire the modules on the two inputs of the Ampt String Optimizer to be on the same row as shown below. Ampt String Optimizer to combiner...
