1.4 Product Description
The RPI-M8/ M10/ M12/ M15/ M15A/ M20/ M20A/ M30is a 3 phase grid-tied
solar inverter. This device converts direct current (DC) electricity from
photovoltaic power collected from PV Array into 3 phase alternating current (AC)
to feed the excess capacity back to the local mains electrical grid. Using of
cutting-edge technology allows wide voltage input range (200~1000V) and high
performance efficiency based on user friendly operation design. In addition,
special DSP (Digital Signal Processor) design decreases the circuit complication
and electronic component. Please note that this device does not support off-grid
function. The following are the features of RPI-M8/ M10/ M12/ M15/ M15A/ M20/
M20A/ M30.
