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

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.
