4.4.2 Load mode adjustment
Users can adjust the load mode as needed on their own, and the default mode is debugging mode (see "load modes
introduction"). The method for adjusting load modes is as follows:
Manual operation is effective only when the load mode is manual mode (15), and tap the Set key to switch on/ off the load
under any main interface.

Note: after system voltage setting, power supply has to be switch off and then on again, otherwise the system may work under an
abnormal system voltage.
After entering into the setting interface, tap the Set key to switch the menu for setting, and tap the Up or Down key to increase or decrease the
parameter value in the menu. Then tap the Return key to exit (without saving parameter setting), or press and hold the Set key to save setting
and exit.
The controller enables users to customize the parameters according to the actual conditions, but parameter setting must be done under the
guidance of a professional person, or else faulty parameter settings may render the system not able to function normally. For details about
parameter settings, see table 3

-5.1 Protection Functions
Waterproof
Waterproof level: Ip32
Input power limiting protection
When the solar panel power exceeds the rated power, the controller will limit the solar panel power under the rated power so as to prevent
excessively large currents from damaging the controller and enter into current-limited charging.
Battery reverse connection protection
If the battery is reversely connected, the system will simply not operate so as to protect the controller from being
burned.
Photovoltaic input side too high voltage protection
If the voltage on the photovoltaic array input side is too high, the controller will automatically cut off photovoltaic input.
Photovoltaic input side short-circuit protection
If the photovoltaic input side gets short-circuited, the controller will halt charging, and when the short circuit issue gets cleared, charging
will automatically resume.
Photovoltaic input reverse-connection protection
When the photovoltaic array is reversely connected, the controller will not break down, and when the connection
problem gets solved, normal operation will resume.
Load overpower protection
When the load power exceeds the rated value, the load will enter into delay protection.
Load short-circuit protection
When the load is short-circuited, the controller can implement protection in a quick and timely manner, and will try to switch on the load
again after a time delay. This protection can be carried out up to 5 times a day. Users can also manually address the short circuit problem
when finding the load is short-circuited via the abnormality codes on the system data analysis page.
Reverse charging protection at night
This protection function can effectively prevent the battery from discharging through the solar panel at night.
TVS lighting protection.
Over-temperature protection.
When the controller temperature exceeds the set value, it will decrease the charging power or halt charging. See the following diagram:

-5.2 System Maintenance
Warning: risk of electric shock! Before carrying out the above checkings or operations, always make sure all power supplies of the
controller have been cut off!
In order to always keep the controller's performance at its optimum level, we recommend that the following items be checked twice a year.
Make sure the airflow around the controller is not blocked and clear away any dirt or debris on the radiator.
Check if any exposed wire gets its insulation undermined due to exposure to sunlight, friction with other adjacent objects, dry rot, damage by
insects or rodents, etc. Repair or replace those affected when necessary.
Verify that indicators function in line with device operations. Note any faults or displayed errors and take corrective measures if necessary.
Check all wiring terminals for any sign of corrosion, insulation damage, overheat, combustion / discoloration, and tighten the terminal screws
firmly.
Check if there are any dirt, nesting insects or corrosion, and clean as required.
If the lightening arrester has lost its efficacy, replace it with a new one timely to prevent the controller and even other devices owned by the
user from being damaged by lightening. on.
Over-temperature protection.
