when PV>10.5V, the output turns off aer N minutes load delay, so the loop is repeated)
(7. LD mode: The clock seng range is 0-12 hours. a. Clock 1 trigger condion: When
PV<10V, clock 1 turns on the load for N minutes (clock 1 is set to 3 hours by default), and
clock 2 executes following clock 1. b. Clock 2 turns off the load for N minutes (clock 2 is
set to 4 hours by default); c. Aer clock 2 execung, the load is always on unl PV>10.5V,
so the loop is repeated)
(8. TO mode: Set the load mer on/off me; the seng range is 0-24 hours.
a. for example, the default seng: turn on load at 18:00, turn off load at 6:00. The
program automacally turns on/off the load at set me).
Remark:
The load switch mode of items 6-8 is OFF by default. Please turn it on as
needed, and set the required me
c. Press and hold MENU to enter the parameter seng
interface :
1. Press MENU to switch among the 8 interfaces in sequence. 2 Press MENU to cancel
the data that has been modified but hasn’t been saved.
d. Restore the default sengs: first press and hold the MENU buon, then turn on the
power of the baery, and the FFFF icon will be displayed on the screen.
2. UP buon descripon
Enter the parameter seng interface: press: UP / (me plus 1 / voltage plus 0.1V); press
and hold: (me / load voltage) values can be accumulated.
Press in default interface aer power-on: switch among (baery voltage/current), (load
voltage/current) and (PV voltage/current).
3. Down buon descripon
Enter the parameter seng interface and press: DOWN / (me minus 1 / voltage
minus 0.1V); press and hold: (me / load voltage) value can be reduced cumulavely.
Press in default interface aer power-on: Switch among baery current, load current,
and PV current.
4. Enter buon descripon
Press: a. In the parameter seng interface: enter to modify parameters / confirm the
modificaon
b. In the baery voltage interface: load ON/OFF.
V. Wire diameter requirements:
Baery output line: (50A MAX) 6AWG--8AWG; at least 8AWG copper wire, less than 2m.
PV input line: 8AWG--10AWG; professionals can select the appropriate electronic line according
to the actual output PV voltage.
