20A PWM Solar Panel Controller Battery Charge Regulator 12V/24V Auto With USB
SAFETY INSTRUCTIONS
1.Make sure your battery has enough voltage for the controller to recognize the battery type before first installation.
2.The battery cable should be as short as possible to minimize loss.
3.The regulator is only suitable for lead acid batteries: OPEN,AGM, GEL
it is not suited for nickel metal hydride, lithium ions or other batteries.
4.The charge regulator is only suitable for regulating solar modules. Never connect another charging source to the charge regulator.
1.Build-in industrial micro controller.
2.Big LCD display,with 5V USB charger
3. PWM charge management.
4.Build-in short-circuit protection,open-circuit protection,reverse protection,over-load protection.
5.Dual mosfet Reverse current protection ,low heat production.
1.Connect the battery to the charge regulator - plus and minus.
2.Connect the photovoltaic module to the regulator - plus and minus.
3. Connect the consumer to the charge regulator - plus and minus.
The reverse order applies when deinstalling!
An improper sequence order can damage the controller!

Display the battery voltage |
|
This iron will be on when solar panel voltage is higher than battery voltage,and it will start charging. |
|
Battery power iron |
|
If this iron flashes means the battery voltage is too low and the output will be cut off until the battery voltage raise to 12.6V |
|
Iron on means output is good. |
