Correctly connect the "+" and "-" of the battery to the corresponding terminals of the controller (the 3rd and 4th wiring terminals from the left). 2. Correctly connect the "+" and "-" of the solar panel to the corresponding terminals of the controller (the 1th and 2th wiring terminals from the left). 3. Correctly connect the "+" and "-" of the load to the corresponding terminals of the controller (the 5th and 6th wiring terminals from the left). 4. The charging indicator light is normally on to indicate that it is charging strongly; flashing to indicate that it is floating charging; if it is off, it means that charging has stopped. 5. When the load indicator is normally on, it means there is output and the load can work; if it is off, it means there is no output and the load cannot work. 6. This product is used for lead-acid batteries, suitable for 17V solar panels.
