Specification: Main material: ABS + PC System voltage: 12V/24V automatic identification Battery input voltage range: 12V/24V automatic identification Maximum input open circuit voltage: 50V Battery type: Lead acid (default)/gel/open Boost charging voltage: Lead acid (default) / colloid: 14.2V / opening: 14.6V Floating charge voltage: Lead acid (default) / colloid / opening: 13.8V Low voltage recovery voltage: Lead acid (default) / colloid / opening: 12.6 Low voltage disconnection voltage: Lead acid (default) / colloid / opening: 10.8V Self-loss: ≤115mA/12V ≤13.5mA/24V Temperature compensation coefficient: -4mV/℃/2V(25°C) Voltage drop of charging circuit: ≤0.25V Voltage drop of discharge circuit: ≤0.12V Working temperature: -15°C - +50°C (continuous work when the product is fully loaded) Working humidity: ≤90% no condensation Size: 133x93x30mm/5.24x3.66x1.18in Type: 10A 20A Recommendations for safe use: 1. This controller automatically recognizes 12V24V. 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 all kinds of lead-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. Note: Due to the different monitor and light effect the actual color of the item might be slightly different from the color showed on the pictures. Thank you! Please allow 1-3cm measuring deviation due to manual measurement. Included: 1 X Solar Controller
