10A Solar Charge Controller: Equipped with an industrial-grade main control chip, this controller features full 3-level PWM charge management, dual MOS anti-backflow circuits, and ultra-low heat generation. These features significantly improve system efficiency. Widely Applied: Compatible with both 12V and 24V systems, this outdoor solar controller includes dual USB ports. The 5V/2A USB port supports mobile phone charging or other 5-voltage devices. Additionally, it safeguards the lithium battery from overcharge and discharge, making it suitable for various settings, including home, industry, and business use.

Features

• The charge controller has a 10A (Amps) capacity, which means it can handle a maximum current of 10 amps from the solar panels.
• The controller is designed for both 12V and 24V systems, making it versatile and suitable for different solar setups.
• The charge controller features dual USB ports with a 5V output. This can be useful for charging USB-powered devices directly from the solar system, providing a convenient power source for small electronic devices.

FAQ's:

How to install?

A: (1)Battery --->(2)Solar panels ---> (3)DC load. Disconnect order is (1)DC load --->(2)Solar panels ---> (3) Battery

Q: What battery type is this controller supported?

A: Pay attention to this regulator is only suitable for lead acid batteries: OPEN, AGM, GEL, not for nickel hydride, lithium, ions, or other batteries.

Q: Why the LCD screen become blank?

A: When the battery voltage is too low, the controller will stop to output ( ≦ 8V, controller turns itself off, LCD is blank, ≦ 10.7V (default), 12V output ports are not available); after the solar panels charging, it will re-output when the battery will return to 12.6V(default).

Q: Why does the controller display 14.4V?

A: If the solar charge controller is set to 12V, when the battery voltage reaches 14.4V or 14.5V, the solar charge controller will stop charging and play a protective role. If it does not enter the floating state, please don't worry, the solar charge controller has a voltage limit value, will be not charge if the battery voltage reaches to 14.4V or 14.5V.

Note:

<1> Make sure the voltage of your battery reach 11V for initial use , so as to start up for the controller to registered the battery type accordingly.

<2> Old batteries may be degraded the capacity after hundereds of cycles, easily drop lower than 8V, which results in the controller will be shut off (LCD screen become totally “DEAD”).

<3> Indoor use only: the working temperature of this controller is -35°C to +60°C. During hot sunny days, the temperature outside might go up to 60-75°C. Please do keep the controller stay in cool and well-ventilated place to maintain good heat dissipation
