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. <br>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. <br>3. This controller is only suitable for various acid batteries (including openings, seals, gels, etc.). <br>4. This controller can only use photovoltaic panels as the charging source. Do not use DC or other power sources as the charging source. <br>5. The controller will heat up when it is running, please pay attention to install the controller on a flat, well ventilated surface.<p>1 x Solar Charge Controller</p><p>1 x English User Manual</p>
