This 200W 30 Ohm resistor is ideal for pre-charging inverters of 2000W or higher in 48V battery systems. When large inverters are connected for the first time - or after being disconnected for a long duration - a significant inrush current can occur. This may cause a hazardous spark at the battery terminals and can also prevent the inverter's internal capacitors from charging correctly, potentially leading to operational failure.
By using this high-wattage aluminium shell resistor, you can safely pre-charge your inverter and eliminate the risk of electrical arcing. The resistor acts as a buffer, allowing the capacitors to gradually charge, making it an essential tool for any safe power system installation involving high-power inverters.
Its durable aluminium housing enhances heat dissipation and ensures long-term reliability. Compact, easy to use, and compatible with standard installation procedures, this resistor is a must-have safety component for installers and DIY users alike.
