Aggregate Power Smoothing
Aggregate power smoothing is the effect of combining output from multiple modules or strings so peaks and dips balance before reaching the inverter.
Product(s)
EI Inverter (EU)
A battery storage ready hybrid inverter available in single phase and three phase options.
GO Inverter
A battery storage ready hybrid inverter that can be AC or DC coupled for new or retrofit solar installations
What does Aggregate Power Smoothing mean?
Aggregate power smoothing is the effect of combining output from multiple modules or strings so peaks and dips balance before reaching the inverter.
Why can array-level aggregation reduce clipping?
Modules on different orientations, or with different shading conditions, rarely peak at exactly the same moment. When their DC power is aggregated, lower-producing sections can offset higher-producing sections, reducing the chance that the total output exceeds inverter capacity.
How it relates to Tigo
Tigo uses this concept to explain why string inverter architectures can clip differently than systems with independent per-module AC conversion.
