2.1 Overview
First of all, thank you for buying and using our JN-K and JN-R PWM mode solar
controllers, in order to better understand and use our products.Please read the manual
carefully before installing and using this product and keep it properly.The installation and
debugging of the product shall be conducted in accordance with this manual.Improper
installation and operation may cause personal injury, equipment damage and property
damage.
This series of controller adopts the most advanced CNC technology design, LCD display,
automatic operation
。
Using pulse width modulation (PWM) type battery charging mode and
unique control technology will greatly improve the battery life.
The charging current of the selected controller should not be greater than 0.3 times the battery
capacity. If it is greater than 0.3 times the battery capacity, the battery will be damaged or the battery life
will be reduced.
Improper installation environment of controller will affect machine performance and may cause
machine damage.
Do not install the controller in flammable or explosive places or storage places for flammable or
explosive materials.
Do not install the controller where there is explosive danger.
Do not install the controller where lightning may strike.
Do not install the controller where there is a lot of salt spray.
When controller is running, it is necessary to ensure the normal air convection around it.
The controller shall be installed in an upright position and shall ensure that the air duct is free from
obstruction.
Warning
！
Before all devices are fully connected, be sure to disconnect the photovoltaic array end, battery
end, load end and other open (circuit breaker) or fuse.
Prevent water from entering controller.
Attention
！
All electrical installations must comply with local and national electrical installation standards.
To ensure safe operation, proper grounding, proper conductor size and necessary short circuit
protection are required.
The connection cable must choose suitable specification, the connection is firm and the insulation is
good.
Check all wiring connections are tight after installation to avoid the risk of heat accumulation due to
virtual connections.
