Solar charge controller MAX series User Manual

5.3.6 Optically controlled spot

5.3.7 Optical delay

5.3.8 Short circuit protection

5.3.9 PWM charging Settings (Lithium batteries)

If the load mode is selected "USE", then you can switch on and off the load

output manually by pressing MENU shortly.

1.If the controller turns off the load due to low voltage protection、

overcurrent protection、short-circuit protection or over temperature

protection, the load will turn onautomatically when the controller recovers

from protection state.

2.Please note: Pushing the MENU button can still activate the function of

the key, even during of the above four kinds protection states.

The controller automatically identifies day and night by measuring the open circuit

voitage of the solar panel. Depending on the location and the different solar panels,

the user can set different day/night threhold voltage).

Liquid, GEL, AGM:The voltage setting

Lithium:The voltage setting

When the night comes, the controller identifies the day/night threhold voltage.

Through modifying the "day/ night threhold delay" to put off the lighting time.

Setting range is 0~60 seconds (step length is 5 seconds) and 1~30 minutes (step

length is 1 minute) (the default setting is 0 seconds).

When the inductive or capacitive load is started, there will be a large current, which

may

trigger the short-circuit protection of the controller and cause the output

turn off. In this

case, the user can turn off the short-circuit protection function.

is enabled, SoF is disabled, and the default state is enabled.

Seting info：keep the defaults

PWM has the potential to cause noise and interference in the system, especially

when using lithium batteries with BMS, PWM charging may trigger BMS protection

,resulting in system failure. Therefore, the customer can choose to turn off the

PWM, in this mode once the batteryvoltage is charged to the preset voltage, the

controller immediately stops charging, until the battery voltage drops, and then

restart the charging.PoN is enabled,PoF is disabled,and the default value is enabled.
