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.2. Install the controller as close to the battery as possible to avoid voltage drop caused by excessively long wires and affect normal voltage judgment.3. This controller is only suitable for various acid batteries (including openings seals gels etc.).4. This controller can only use photovoltaic panels as the charging source. Do not use DC or other power sources as the charging source.5. The controller will heat up when it is running please pay attention to install the controller on a flat well ventilated surface.
