Frequently Asked Questions
What does the IP68 protection rating guarantee?
The IP68 rating guarantees that the solar charge controller is fully dust-tight and waterproof. It has been tested to withstand water submersion up to a depth of 1.5 meters for 72 hours, making it highly reliable for outdoor environments.
Does this solar controller support lithium batteries?
Yes, it supports both traditional lead-acid batteries and lithium batteries. The charging profile for lithium batteries can be manually configured, and its PWM/CV charging modes are fully compatible with battery protection boards.
How is the 2.4G wireless communication utilized?
The integrated 2.4G wireless communication, along with infrared support, allows you to configure parameters, adjust output settings, and monitor the controller status remotely without needing physical button access.
What is the "Morning Light" and "Five Time Periods" function?
These functions allow you to divide the lighting duration into five custom time zones, each with its own output dimming power. The morning light function dynamically adjusts output power as daylight approaches to maximize efficiency.
What safety protections are integrated into the controller?
It features comprehensive safety measures including battery and solar panel reverse connection protection, nighttime reverse discharge prevention, low voltage protection, and LED output short-circuit/open-circuit protection.
What is the benefit of temperature-compensated battery management?
It automatically adjusts charging parameters based on ambient temperature (-4mV/°C/2V), keeping the battery operating under optimal charging conditions. This extends overall battery life by more than 50%.
