Power Rating
If the applied voltage is over rated voltage, charging the module should be stopped.
And the allowable low voltage level of the module depends on the user’s requirements,
but full discharging to 0V does not affect the module performance.
Temperature
The module has its optimal operating temperature range of -40 to 65. Over 70
℃
,
charging and discharging should be stopped to preserve its performance and life cycle.
Do not expose to direct sunlight
For installation do not make the module expose to direct sunlight due to temperature
increase inside the module.
Maintenance
The module has its projected life over 10years at rated voltage and +25
℃
. However
the life cycle of the module may be decreased in high temperature condition or over
voltage charging.
If following abnormal module performances are detected, operation should be stopped
and checking the electrical & mechanical connections is recommended.
- Detection of high temperature in normal operating conditions
- Internal resistance increase or initial voltage drop increase
- Deformation of the module case
