AC Grid
Intelligent
device
1. PV Panel: Provide DC power to inverter
2. Inverters: 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 the PV array.
3. QF1/QF2 Breaker: DC breaker with 25A
4. QF3 Breaker: Refer to the following table to choose the AC breaker.
Refer to the following table to choose the AC breaker.
Type Nominal AC Current [A] Rate current of AC breaker[A]
BNT050KTL 75 100
BNT060KTL 90 125
5. LPS: Lightning protection system, refer to the following options:
AC side, nominal discharge current 20KA, second grade lightning protection, protection voltage 2.5KV
DC side, nominal discharge current 20KA, second grade lightning protection, protection voltage 2.5KV
6. The wiring distance between the inverter and the distribution box should be at least 5 meters.
7. Utility: Referred to as “grid” in this manual, i.e. the media your electric power company provides power
to your place. Please note that Inverter can only be connected to low-voltage systems (namely, 230/400Vac,
50/60Hz).
