Q&A
General Performance and Benefits
Q: How do I know if my SoftStartUp is working?
A: Look at the LED indicators. Two green lights indicate a 50-amp service, and one green light means a 30-amp connection. You should also notice smoother appliance startups with no tripped breakers or flickering lights.
Q: Will SoftStartUp reduce my RV’s power consumption?
A: It does not lower the normal running power of appliances. Instead, it manages the inrush current at startup to prevent power spikes and interruptions.
Compatibility and Usage
Q: Can I use SoftStartUp with a 30-amp power source?
A: Yes, by using the provided 30-to-50-amp adapter, you can safely connect to a 30-amp supply.
Q: Will it work with my generator in ECO mode?
A: No. ECO mode does not provide sufficient startup power for high-demand appliances like air conditioners.
Installation and Setup
Q: Do I need special tools to install SoftStartUp?
A: No tools are required. It is a plug-and-play device that connects directly between the power source and your RV.
Q: Can I use SoftStartUp in combination with a surge protector and voltage booster?
A: Yes. Plug the surge protector into the power pedestal first, followed by the voltage booster, then connect the SoftStartUp, and finally plug in your RV.
Environmental and Maintenance Considerations
Q: Can SoftStartUp be used in extreme weather conditions?
A: Yes, but avoid direct sunlight in high heat and protect it from freezing water in cold conditions.
Q: Does SoftStartUp require maintenance?
A: It is maintenance-free but should be periodically checked for secure connections and cleaned of dust or debris.
Customer Support and Warranty
Q: What should I do if my SoftStartUp is not performing as expected?
A: Check connections, verify power sources, and consult the troubleshooting guide. If issues persist, contact customer support.
Q: What is the warranty policy for SoftStartUp?
A: The device comes with a 90-day satisfaction guarantee and a 1-year limited warranty. Contact support for claims or technical assistance.
Troubleshooting
Problem: No LED Indicators Showing After Plugging In To Power Source
- Ensure all power connections are secure and properly plugged in.
- Verify that the campground power supply is functioning correctly.
- If using a generator, confirm that it is turned on and providing adequate power.
- If the issue persists, contact tech support
Problem: Appliances Still Tripping Breakers
- Check that the SoftStartUp is installed correctly between the power source and the RV.
- Ensure that the total power demand of your appliances does not exceed the available power supply.
- If using a 30-amp connection, verify that the correct adapter is used.
- Inspect the RV’s electrical system for any existing wiring or breaker issues.
Problem: Air Conditioner Does Not Start Smoothly
- Confirm that the SoftStartUp is connected properly and LED indicators show power availability.
- Check if the generator is operating in ECO mode; if so, disable it.
- Ensure that the air conditioner is within the power limitations of the generator or campground supply.
- If an additional soft starter is installed on the A/C, confirm that it is functioning properly alongside the SoftStartUp.
Problem: SoftStartUp Works on Shore Power but Not with Generator
- Make sure the generator is providing stable voltage output.
- Disable generator ECO mode if active.
- If using an EMS surge protector, verify if a generator bonding plug is required.
- Try resetting the SoftStartUp by unplugging and reconnecting it.
Problem: Dimming Lights When Appliances Start
- Verify that the SoftStartUp is installed in the correct sequence.
- Check if the total power consumption exceeds the available amp capacity.
- Ensure that no loose or damaged wiring exists within the RV’s electrical system.
Problem: Surge Protector Tripping When Using SoftStartUp
- Connect the surge protector directly to the power pedestal before the SoftStartUp.
- Ensure the surge protector is rated for the amperage of your RV’s power system.
- Check for campground power fluctuations that may be causing the surge protector to activate.
