Introduction
This inverter can provide power to connected loads by utilizing PV power, utility power
and battery power.
Figure 1 Basic hybrid PV System Overview
Depending on different power situations, this 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 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.
