Figure 1 Basic hybrid PV System Overview
Depending on different power situations, this hybrid inverter is designed to generate
continuous power from PV solar modules (solar panels), battery, and the utility.
When MPP input voltage of PV modules is within acceptable range (see specification
for the details), this inverter is able to generate power to feed the grid (utility) and
charge battery. This inverter is only compatible with PV module types of single
crystalline and poly crystalline. Do not connect any PV array types other than these
two types of PV modules to the inverter. Do not connect the positive or negative
terminal of the solar panel to the ground. See Figure 1 for a simple diagram of a
typical solar system with this hybrid inverter.
Note: By following the EEG standard, every inverter sold to German area is not
allowed to charge battery from Utility. The relevant function is automatically disabled
by the software.
This manual is for qualified personnel. The tasks described in this manual may be
performed by qualified personnel only.
