Product Features

Thank you for choosing our product This device is a PWM 12/24V 30A charge controller ideal for many applications. It’s flush mount design makes it perfect for solar power systems in RVs and boats. Please be sure to read through the following pages and familiarize yourself with the features and settings of the controller.

These charge controllers have these features:

PCA common negative design, necessary for all negative grounded solar power systems.
12/24V auto recognition for Flooded, AGM and GEL batteries. Lithium battery must be manually set

PWM 3-phase charging: equalize – boost- float (for Flooded, AGM and GEL).
Flush mount design for easy installation, RV fixture or similar installation.

Back light LCD display with informative pages (system status, current, voltage, voltage value settings, etc).
5V USB port for mobile device load. (plug and play)

Multiple built in protections including solar reverse connection, battery reverse connection, and battery over-discharge protection.

INSTALLATION NOTES

IMPORTANT REMINDERS

The battery must always be connected to the controller first
Please note that the max PV input voltage is 55V open circuit voltage (Voc), so do not use solar module(s) with working voltage (Vmp) of more than 4OV (refer to solar (PV) module specs).
Please note the max PV input power is 450W/12V or 900W/24V. Please do not exceed the rated power.
Do not change any settings in the “L” battery mode if you are not using a lithium battery.
In the LI battery mode, you must set the battery system voltage (12 or 24V) manually.
If you would like to check the information in the “Li” battery mode settings, but not alter any settings, then you MUST remember to keep the right system voltage set (12 or 24V) before exiting from the settings.

HARDWARE SUGGESTIONS

For maximum PWM charge efficiency, we suggest using solar modules with an output of 18V (Vmp) for a 12V battery system, and 36V (Vmp) module for 24V battery systems. You can still use modules with higher voltages but it may lead to a slightly lower charge efficiency. In all cases the solar (PV) input voltage (Vmp) must be higher than the battery voltage.
For safety and protection we suggest using a DC breaker or fuse between both the solar and the controller, as well as between the controller and the battery.
