9. External temperature probe
10. RJ45 port, connected to the remote control board through the network cable and
synchronized with the LCD screen (this port is reserved and the remote control board is oponal)
11. PV+ (connected to the posive electrode of the solar panel)
12. PV- (connected to the negave electrode of the solar panel)
13. B+ (connected to the posive electrode of the baery)
14. B- (connected to the negave electrode of the baery)
15. L+ (connected to the posive electrode of the load)
16.

III. Descripon of basic funcons
1. PV (solar panel input):
a. The maximum open circuit voltage of PV is 100V.
b. PV integrates an-reverse (reverse connecon alarm E8, no charging, please eliminate
the fault).
c. 12V baery, PV input voltage range is 16-80V;
d. 24V baery, PV input voltage range is 32-80V;
2. Baery output funcon
a. Idenfy 12//24Vbaery automacally; the maximum charging current is :30A
b. An-reverse connecon (E1 alarm).
3. Load output funcon (default OFF).
a. Rated maximum output current30A (12/24/V).
b. Overcurrent protecon >35A.
c. Short circuit protecon (E4 alarm; please eliminate the fault).
d. Load output over/undervoltage protecon, recovery voltage; refer to the set voltage.
4. Over-temperature protecon
a. Reduce load in case of over-temperature: the charging current is always 16-18A when
the heat sink temperature ≥ 75°C.
