1. Introduction
This manual provides essential information for the safe and efficient operation of your Y&H 60A PWM Solar Charge Controller. Please read these instructions carefully before installation and use to ensure optimal performance and longevity of the product.
2. Safety Instructions
- Ensure the battery has sufficient voltage for the controller to recognize the battery type before the first installation.
- The battery cable should be as short as possible to minimize loss.
- The regulator is only suitable for lead-acid batteries (OPEN, AGM, GEL). It is not suitable for nickel metal hydride, lithium-ion, or other batteries.
- The charge regulator is only suitable for regulating solar modules. Never connect another charging source to the charge regulator.
3. Product Features
- Built-in industrial micro-controller.
- Large LCD display with adjustable parameters for float charge voltage, low voltage discharge, low resistance, and load timer.
- Dual USB output (5V/2A) for charging mobile devices.
- Fully automatic PWM charge management.
- Multiple protection functions: power-off memory, over-heat, low voltage discharge, short circuit, open circuit, overload, and overcharge protection.
- MOSFET reverse current protection, low heat production.
4. Setup and Installation
Follow these steps for proper connection of the solar charge controller:
- Connect the battery to the charge regulator (plus and minus).
- Connect the photovoltaic module to the regulator (plus and minus).
- Connect the consumer to the charge regulator (plus and minus).
Important: Reverse order applies when uninstalling!
An improper sequence can damage the controller!

5. Operating Instructions
5.1. LCD Display and Key Functions
The large LCD screen displays all parameters. The controller features three buttons for navigation and settings:
- MENU Button: Short press to switch between different display interfaces. Long press for 3 seconds to enter the settings page.
- UP Button: Press to increase values.
- DOWN Button: Press to decrease values.
The display shows various parameters including battery voltage, solar panel charging status, load status, accumulated charge/discharge ampere-hours, ambient temperature, and load mode.

5.2. Parameter Settings
To adjust parameters:
- Long press the MENU button for 3 seconds to enter the settings page.
- Use the UP/DOWN buttons to adjust the desired value.
- Long press the MENU button again to save the setting and exit.
Parameters that can be adjusted include float charge voltage, low voltage disconnect, low voltage reconnect, and load timer settings.

6. Maintenance
To ensure the long-term performance and reliability of your solar charge controller, regular maintenance is recommended:
- Keep the controller clean and free from dust and debris.
- Periodically check all wire connections to ensure they are secure and free from corrosion.
- Ensure adequate ventilation around the controller to prevent overheating.
7. Troubleshooting
Refer to the table below for common issues and their solutions:
| Situation | Probable Cause | Solution |
|---|---|---|
| Charge icon not on when sunny | Solar panel opened / Wiring set again | Reconnect |
| Load icon on | Battery low | Recharge |
| Load icon slow flashing | Over load / Short circuit protection | Reduce load watts / Remove short circuit, 1 minute or automatic recovery |
| Power off | Battery too low / protection | Check battery/connection |
