Damage to the MPPT controller caused by the following conditions, or other damages will
not be covered by our warranty.
When configuring the PV array, ensure that the maximum short-circuit current on the DC
side is within the allowable range of the MPPT controller, otherwise the MPPT may be
irreparable.
When configuring the PV array, make sure that the open circuit voltage of each PV string
does not exceed the maximum input range of the MPPT controller, otherwise the MPPT
controller will be irreparable.
The selected controller charging current should not be greater than 0.3 times the battery
capacity. If it is greater than the battery will be damaged or the battery life will be reduced.
Improper selection of the MPPT controller installation environment will affect machine
performance and may cause machine damage.
Do not install the MPPT controller in a flammable or explosive place or in a place where
flammable or explosive materials are stored.
Do not install the MPPT controller in an explosive location.
Do not install the MPPT controller in a location where it may be exposed to lightning strikes.
Do not install the MPPT controller in a place with a lot of salt spray.
Good ventilation is required when the MPPT controller is in operation.
The MPPT controller needs to be installed upright and ensure that the air duct is
unobstructed.
Warning!
Always disconnect the PV array, battery, load, etc. (circuit breaker) or fuse before all
devices are fully connected.
Prevent water from entering the inside of the controller.
Note!
All electrical installations must comply with local and national electrical installation
standards.
To ensure safe operation, proper grounding, proper conductor size and the necessary
short-circuit protection are required.
The connection cable must be selected to the appropriate specifications, and the
connection is secure and well insulated.
After installation, check that all wiring connections are tight to avoid the risk of heat build-up
due to virtual connections.
