4. System Diagram
The typical connection diagram for the entire PV system is shown in the
following figure.
1. PV Panel: Provide DC power to inverter.
2. EATON ETN1000 / ETN2000 PV Inverter converts DC (Direct Current)
power from PV panel(s) to AC (Alternating Current) power. Because
Inverter is grid-connected it controls the current amplitude according to
the PV Panel power supply. Inverter always tries to convert the
maximum power from your PV panel(s).
3. Connection system: This “interface” between Utility and PV-Inverter
may consist of electrical breaker, fuse and connecting terminals. To
comply with local safety standards and codes, the connection system
should be designed and implemented by a qualified technician.
4. Utility: Referred to as “grid” in this manual, is the way your electric
power company provides power to your place. Please note that
Inverter can only connect to low-voltage systems (namely, 220,
230VAC, 50/60Hz).
