CDIYTOOL 100A MPPT Solar Charge Controller User Manual
Model: 4yhujuyj
Kupu Whakataki
This manual provides essential information for the safe and efficient operation of your CDIYTOOL 100A MPPT Solar Charge Controller. This controller is designed for 36V, 48V, and 60V battery systems and features an LCD display, multiple load control modes, and dual USB outputs. Please read this manual thoroughly before installation and use.
The controller automatically adapts to 36V/48V/60V systems and is not suitable for 12V/24V systems. It utilizes innovative MPPT technology for high tracking efficiency, detecting the maximum charging current.
Nga Tohutohu Haumaru
Always adhere to the following safety guidelines to prevent injury and damage to the controller or other components.
- Me whakarite he rawaka te voltage for the controller to recognize the correct battery type upon first use.
- Connect the battery to the controller first, then connect the solar panels. Reversing this order can damage the controller.
- Ko te nui o te whakauru voltage is 50V. Ensure your solar panel configuration does not exceed this limit. For example, a 19V photovoltaic panel matches a 12V battery, and a 38V photovoltaic panel matches a 24V battery. When a 38V panel is connected, the maximum voltage may reach 42V.
- The controller is suitable for various battery types (including open, lead-acid, gel, and lithium batteries). Refer to the controller's settings for specific battery types.
- The controller provides protection against overvoltage, short circuit, overload, overcharge, and over-discharge.
- Kaua e ngana ki te wetewete, ki te whakatika rānei i te pūmana whakahaere māu ake. Whakapā atu ki ngā kaimahi whai tohu mō te mahi tiaki.
