Package: PWM Controller 60A X1Manual(English) X1 Steps: Connect solar system in this order: 1.battery--> 2. PV arrayload--> 3.DC load, and disconnect solar system in the reverse order >3. >2. >1. Battery must be connected first ! Never connect soalr panel array to controller Without/Before connect battery. DO NOT connect any inverter/wind/Alternator or Charger into the charge controller directly ! You should connect with battery and add fuse .The fuse should be installed as close to battery as possible，the suggested distance is about 150mm Controller‘s Button Operation Instructions Interface browsing: Press "+" or "-" to browse different parameters. Turn ON/OFF Load: Set the load to 24H working mode frist, then on the main interface press "-" to TURN ON/OFF the load terminal's output. Parameter setting modification: press and hold "+" on the settable interface to enter the parameter setting, then press "+" or "-" to adjust the parameter value, and finally press and hold "+" to confirm and save the parameter setting. (press and hold "-" means: do not save the parameters and restore the last parameter settings) Restore factory settings: press and hold "+" on the ambient temperature interface to restore factory settings. Under the interface of Accumulated KWH, press and hold “＋” button can clear the value; When no operation 30s, the interface will be back to main interface, and back-light will be turned off.
