Note: 

• This controller automatically recognizes 12V/24V. When installing for the first time, please make sure that the battery has enough voltage so that the controller can recognize the correct battery type.

• Install the controller as close to the battery as possible to avoid voltage drop caused by excessively long wires and affect normal voltage judgment.

• This controller is only suitable for all kinds of lead-acid batteries (including openings, seals, gels, etc.).

• This controller can only use photovoltaic panels as the charging source. Do not use DC or other power sources as the charging source.

• The controller will heat up when it is running, please pay attention to installing the controller on a flat, well-ventilated surface.

• Please allow slight measurement differences due to different manual measurements.
