With roots in the RV industry’s formative years, Parallax Power Supply has access to extensive archives and established networks.
Steel enclosures and North American manufacturing have always been hallmarks of their product line, just as they are in the modern electrical systems found in homes and businesses.
The Parallax Power Supply 7300 series offers reliable power supply inverters to their customers.
However, you may occasionally come across consumers who are having difficulties with their Parallax Power Supply 7300. Due to this, we will provide a list of pressing problems with the Parallax Power Supply 7300 and its solutions. Let’s dive deeper into them!
Parallax Power Supply 7300 Troubleshooting:
Today, keeping one’s batteries charged is the primary reason why most people invest in an inverter charger.
However, many customers have reported that their motorhome’s batteries aren’t being charged from the onboard power source. An issue with the battery or power supply is usually to blame for this issue.
The power output from the source needs to be examined to determine the issue’s root. Using a multimeter or other voltage measuring instrument can help you diagnose power-related faults with your electronics.
If the inverter charger isn’t working, check the various battery terminals and the connections. Hopefully, that will lead you to the source of the charging problem.
Over time, it’s not unusual for the connection points to deteriorate. Because of this, it is recommended that the connection points be cleaned if the device has been in use for an extended period.
Before touching the connection points, ensure the power source and the batteries are disconnected. After cleaning the connection points, you may put everything back together again, and the batteries should begin charging.
2. Check Battery Connections
The battery may be a problem if you’ve had the setup for a while and the inverter suddenly stopped operating or turning on. Cleaning and tightening the battery connection is usually all that’s needed to fix a faulty battery connection.
It could be that the battery itself has become rusted or corroded. Check the battery for corrosion; if any is found, remove it from the RV, and clean it.
To clean the terminal, you should use a stiff toothbrush dipped in a solution of baking soda and hot water to gently scrape the device.
It is recommended to use a paper towel to dry the connectors after cleaning them after the corrosion has been removed. To switch the inverter back on, reconnect the connections.
3. Beeping Issue
Users have also reported that the device randomly begins beeping. It might become very frustrating if you can’t find a solution to this issue. If your device is making a beeping noise, it probably has a low battery.
When you put too much stress on the device, it may also begin beeping.
As a result, to silence the annoying beeping, you need to inspect the electrical devices that are linked to your air unit. In addition to that, you should examine the condition of the batteries in your RV.
Your batteries may have failed if the beeping started at the same time as you began to have charging problems. Batteries should be changed every few years; if you haven’t done so recently, now is probably a good time to do so.
However, if your batteries are fine, you should examine the other devices plugged into your unit.
The inverter charger’s beeping sound can usually be silenced by reducing the load on the unit. In the event that you are unable to determine the cause of the problem, it is recommended that you have a professional mechanic inspect your RV.
4. Check Power Switch
A faulty switch could be the cause of a power inverter’s failure to turn on when the switch is pushed. It’s easy to check if the proceeding is safe after you’ve determined if further investigation is required.
Disconnect the power inverter from the power source, then connect and power up an additional device. Getting a new power switch is necessary if the old one won’t turn it on.
To swap the switch, it is essential to contact an electrician and purchase a new unit. If you feel comfortable, you can replace it on your own.
5. Wiring Issue
Customers who have installed the inverter charger on their own are more likely to run into this issue. In most cases, this is due to improper wiring during installation, which may be rectified by reading the user manual and making the necessary adjustments.
However, if you are unsure of your ability to do so, a professional technician should be hired. That should fix any wiring problems you’re having. You can also contact Parallax Power at their listed phone number with any inquiries or concerns you may have.
You can contact them with any problems you’re having with their products, and they’ll assist you in resolving them. Since you obviously can’t take your RV in right away, this is your best bet until you can get it fixed professionally.
Additionally, if you are experiencing problems that are not addressed here, please contact Parallax Power’s customer service.
Together, you’ll determine what’s wrong with the gadget and then experiment with potential solutions based on their recommendations. A warranty is available for this power supply inverter if it was purchased within the last few months.
Unfortunately, consumers’ inability to charge their RV batteries remains the most frequently reported issue. If this is the case, examine the terminals where the battery and the device are connected.
5. Check The Device
If the power switch and battery are OK, the issue may lie within the inverter, which necessitates a diagnostic check. Once you have a basic understanding of how the system functions, obtaining a diagram of the inverter will be your best next step.
Now that you have the schematic, you may open the housing and examine each contact point to ensure it is functioning correctly.
If the contacts look fine, you can continue examining the other components. The voltmeter must be checked first, followed by individual components.
It’s best to be extra careful and ensure you’re out of harm’s way by turning off the power and any other potential hazard sources.
6. Check For Older Parts
Once you’ve identified the malfunctioning components, you can move on to replacing them with new ones. If you can, it’s best to get replacement components made by the same Parallax that has caused the original series.
Now that you have everything you need, you may remove the inverter, throw away the old parts, and carefully replace them with new ones
When taking it apart, keep in mind the order in which the components were taken apart and reconnected. In this way, the replacement component may be installed properly.
