FAQs

I currently have two OutBack Power FXR 3000W inverters stacked and wired with two legs of 120V. Occasionally, one leg will draw more than 3000 watts and the circuit breaker will flip the inverter off. However, we are not exceeding the 6000W overall capacity. Will installing a FW-X240 solve our brown out issues by allocating power from the other inverter to the leg that has temporarily exceeded its power capacity?
Yes, installing an OutBack FW-X240 transformer can help mitigate your issue by balancing the load across both inverters. Here's how it works and why it could solve your problem:
- How the FW-X240 Works
  The FW-X240 transformer is designed for systems like yours with two stacked inverters, where each inverter supplies 120V on separate legs. Its key functions include:
  - Load Balancing
    The FW-X240 can transfer excess power from one leg (inverter) to the other if one leg exceeds its capacity. For example, if one leg exceeds 3000W and the other leg is underutilized, the FW-X240 bridges the gap by sharing power across the legs, up to the combined capacity of 6000W.
  - Supplemental Power
    It can provide additional power support during short-term surges on one leg, reducing the likelihood of breaker trips or brownouts.
- Benefits of Adding the FW-X240
  - Improved Load Handling
    Prevents overloading of a single inverter by dynamically redistributing power, especially for unbalanced loads.
  - Avoiding Brownouts
    Balances voltage and prevents voltage drops on one leg when it is overloaded.
  - Increased System Stability
    Keeps your system operational by leveraging both inverters’ combined capacity efficiently.
- Things to Consider
  - Wiring and Installation
    Proper installation of the FW-X240 transformer is critical. It should be wired into your AC distribution panel and integrated into your system's stacking setup.
  - Breaker Ratings
    Ensure that your circuit breakers are appropriately rated for your system's loads. A 30A breaker per inverter is typical for 3000W inverters, for example.
  - System Configuration
    Verify your inverters are stacked correctly (either in series or parallel) to ensure seamless operation with the FW-X240.
  - Load Assessment
    Review your loads to identify if specific appliances consistently cause overloads. Redistributing loads across circuits might also help.
- Limitations
  The FW-X240 cannot increase the total capacity of your system. If both inverters are already operating near their maximum combined capacity, adding an FW-X240 won’t prevent overloading in such cases. If your loads are very unbalanced, it’s best to distribute high-power appliances across both legs manually.
