Product Description
RBL-20A 12V / 24V Solar Panel Cell PV Charge Controller

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,all adjustable parameter.
3.Fully 4-stage 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.
