1. Introduction
SP5000 Premium can provide power to connected oads by uti izing PV power, uti ity
power and battery power.
Figure 1 Basic hybrid PV System Overview
Depending on different power situations, this hybrid inverter is designed to generate
continuous power from PV so ar modu es (so ar pane s), battery, and the uti ity. When
MPP input vo tage of PV modu es is within acceptab e range (see specification for the
detai s), this inverter is ab e to generate power to feed the grid (uti ity) and charge
battery. This inverter is on y compatib e with PV modu e types of sing e crysta ine and
po y crysta ine. Do not connect any PV array types other than these two types of PV
modu es to the inverter. Do not connect the positive or negative termina of the so ar
pane to the ground. See Figure 1 for a simp e diagram of a typica so ar system with this
hybrid inverter.
Note: By fo owing the EEG standard, every inverter so d to German area is not a owed
to charge battery from Uti ity. The re evant function is automatica y disab ed by the
software.
