2PCS RTD-20A 12V 24V Solar Panel Charge and Discharge Controller LCD PWM Solar Regulator for Home PV System Mini Charger Control
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.
PRODUCT FEATURES
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.
SYSTEM CONNECTION
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!
