1.4 Product Description
This device is a single-phase grid-tie solar inverter. It converts direct current
(DC) electricity from the PV array into single-phase alternating current (AC) to
feed the excess generated power back to the local grid.
This inverter allows for a wide voltage input range (100~550VDC) and has a
high performance efficiency and user friendly design and operation. In addition,
the special DSP (Digital Signal Processor) design reduces the complexity of
the circuit and electronic components. Please note that this device does not
support off-grid function. The features for RPI H3A / H4A / H5A are shown
below.
