This article details the upgrade of my RV's electrical system, focusing on two key components: the installation of a Power Watchdog PWD50-EPOH surge protector and the replacement of a failing converter/charger. Experiencing persistent low voltage warnings and dimming lights, even with minimal loads, pointed to a problem beyond my aging lead-acid battery. While replacing the battery initially seemed like the solution, further investigation revealed the true culprit: a faulty converter/charger.This upgrade project involved a straightforward but crucial two-part process. The first part focused on installing the Power Watchdog PWD50-EPOH to safeguard the system against power surges. The second part involved replacing the old converter/charger with a newer model, chosen for its compatibility with future lithium battery upgrades. This article will walk you through each step of the installation process, highlighting important safety precautions and offering insights for anyone looking to improve their RV's electrical reliability and longevity.

Troubleshooting Dimming Lights and Low Voltage Issues
Experiencing dimming lights and low voltage warnings in my RV, even without added loads, was concerning. Initially, I suspected a failing lead-acid 12V battery after several years of use. Replacing the battery didn't resolve the problem.
Further investigation led me to believe the converter/charger, responsible for charging the battery and powering the 12V system, was the culprit. Reducing 12V usage seemed to temporarily mitigate the issue, strengthening my suspicion.
This confirmed my theory and prompted me to order a new converter/charger. Fortunately, a friend provided a spare unit, saving me the cost of the one I'd already purchased.
Installing the Power Watchdog Surge Protector
Before installing the new converter, I tackled the Power Watchdog PWD50-EPOH installation. I chose a location on the wall near the main power entrance for easy access and wire routing.
The installation was straightforward: mounting the unit securely and connecting the input and output wires. I ensured I had sufficient slack in the wires to make the connections comfortably.
Properly stripping the wires and securing the connections was crucial. Although I have electrical experience, always prioritize safety and consult a professional if unsure.
Replacing the Converter/Charger
Replacing the converter/charger involved a similar process. I disconnected the power from the outside breaker, shut off the battery, and disconnected the 12V battery before commencing.
The swap was relatively straightforward, as the new unit was a near-identical replacement. The main difference was the new unit's compatibility with lithium batteries, which I plan to upgrade to in the future.
After connecting the new converter, I reconnected the power and tested the system thoroughly. All voltages and functions were verified using the app and multimeter.
Conclusion and Product Review
Both the Power Watchdog PWD50-EPOH and the new converter/charger installation went smoothly. The Power Watchdog provides peace of mind by protecting my RV's electrical system from surges.
The converter upgrade resolved the previous low voltage issues, ensuring reliable power for my 12V appliances. The added lithium battery compatibility is a future-proofing benefit.
I highly recommend both products. The Power Watchdog offers essential surge protection, while the new converter ensures reliable power and is ready for future lithium battery upgrades. The installation process was manageable even for someone without extensive electrical experience, but professional help is always a good option for safety.
