System Diagram with Inverter Electrical connection
This unit or system is provided with fixed trip limits and shall not be aggregated
above 30 kW on a single Point of Common Connection.
PV Panel: Provide DC power to 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).
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.
Utility: Referred to as “grid” in this manual, is the way your electric power
company provides power to your place.
