Unlock the full potential of your solar energy system with the Bluetti PV VOLTAGE STEP DOWN MODULE (D300S). Designed specifically for models AC300, EP500, and EP500Pro, this innovative module allows seamless integration with rigid solar panels, enabling a maximum solar charging capacity of 2400W. Perfect for those who already have solar panels and PV grid-connected inverters, the D300S effectively steps down high open-circuit voltage (up to 550V) to meet the input limits of your devices (140V/150V). Voltage Regulation: Reduces the voltage from rigid panels to 120V, ensuring compatibility. High Power Support: Handles a maximum input and output of 3000W, providing efficiency when you need it most. Durable Design: Rated IP54 for protection against dust and water, making it ideal for outdoor use. Advanced Safety Features: Includes short circuit protection, over-voltage protection, and thermal safeguards. With a high efficiency rate of 97.8%, the D300S operates effectively within a temperature range of -10°C to 40°C and can be stored in conditions from -20°C to 40°C. Weighing only 7KG (15.4lbs) and compactly sized (350*216*120mm), it’s easy to integrate into your existing solar setup.
