1.0 Introduction
This manual provides safety and installation instructions for charge controller. Allto Solar assumes no responsibility for
loss, damage or expense resulting from improper installation, handling, or use.
2.0 Safety Precautions
Before installing this product, read all safety instructions in this document.
• All installations must be performed in compliance with any applicable local codes.
• The batteries must be same of type, make and age if you connect several batteries in parallel or series.
• Avoid exposing solar panel to partial sunlight or shadows, partial sunlight can cause hot spot on the solar panel.
• Ensure input voltage does not exceed 30 VDC to prevent permanent damage.
• The charge controller is powered by sunshine, mini voltage for the solar panel is 15V.
• Designed for 12V battery, do not use it for 6V or 24V battery. (two 6V batteries may also be used if connected in series;
multiple 12V batteries also may be used if connected in parallel).
• Do not attempt to recharge non-rechargeable battery, converse with your battery dealer for more info before usage.
• Ensure the polarity is correct when connecting the charge controller to battery and solar panel.

4.0 How to Use
The charge controller has 3 modes: 12V, 12V AGM, 12V Lithium, It is important to understand the differences and
purpose of each charge mode. Always check with battery manufacturer to confirm the right charge mode for your specific
battery. Do not operate the charger until you confirm the appropriate charge mode for your battery. Below is a brief
description:
For charging 12-volt Wet Cell, Gel Cell, Enhanced Flooded, Maintenance-Free and
Calcium batteries. When selected, the 12V LED will illuminate
For charging 12-volt AGM batteries. When selected, the 12V AGM LED will illuminate.
For charging 12-volt lithium-ion batteries, including lithium iron phosphate. When
selected, the 12V Lithium LED will illuminate.
Caution*****Use 12V Lithium mode with extreme care, this mode should only be used with 12 volt lithium batteries that
have a built-in battery management system(BMS). Lithium-ion batteries are made and constructed in different ways and
