Overview
This chapter introduces inverter and describes its functional model, network application,
appearance, dimensions, working process etc.
2.1 Functional Models
Function
The inverter is a single-phase grid-tied PV string inverter (transformer less) that converts
the DC power generated by PV strings into AC power and feeds the power into the power
grid.
WARNING
The
inverter
is transformerless inverter. Add an isolation transformer before
grounding the positive/ negative terminal of PV modules (like Thin Film
module) for operation.
WARNING
Do not connect PV modules in parallel to several PV inverters for operation.
Models
