4.1 Protection Functions
Waterproof
Waterproof level: Ip32
Input power limiting protection
When the solar panel power exceeds the rated power, the controller will limit the charging 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 batter y 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 cut off output after a time delay.
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:
4.2 System Maintenance
In order to 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, dr y 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.
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!
