Do RVers Really Need A Power Monitor System?

Posted on by

I see that question all the time on Facebook and most of the Blogs that I read.  For the simple, easy, straight forward answer, YES you do.  There are so many factors involved here that I can not possibly cover them all in a single post but, I would like to cover the basics so that you can better understand why you need a Power Management system of some kind.

1. You need to know what the AC (Shore Power) voltage is inside your rig.  This is the power that indirectly powers lights, water heater, microwave, furnace, charger for the 12-volt battery system, etc.  If the voltage gets below 102 volts and should stay there for a few minutes it would be possible to sustain approximately $1200 of damage or more.

So what do you need?  You will need an AC Line Voltage Monitor.  The unit shown below is plugged into an AC wall outlet that you can see and will monitor what the line voltage is.  If it should go below 105 volts you need to unplug your rig from the outside power pedestal until the voltage goes back to normal.

AC Line Voltage Monitor

So how do you know when the outside power pedestal is back to normal.  You plug the Voltage Monitor into the 125 volts two pin socket in the power pedestal and see what the monitor reads.  It should read 110 volts or higher up to 125 volts.  The same caution goes for overvoltage.  You should unplug the rig form the power pedestal if your Voltage Monitor begins to read over 122 Volts.  Plug the Voltage Monitor into the power pedestal and watch for the voltage to drop to below 122 Volts.

Could this monitoring of the voltage be done for less money?  Yes, by using a cheap Digital Volt Meter  pictured below;

 Digital Volt Meter

You could plug the test leads that come with the meter into the meter and then the other ends of the test lead into the slots on the AC wall socket. (Caution do not leave unattended) Or you could make up a cord from a 6-foot extension cord and the test leads that come with the meter.  See below for an example.

AC Cord With Test Meter Leads

2. Next is  The Polarity Tester.  This is used to be sure that the Neutral wire of the power line is not reversed with the positive lead of the power line.  If that were to happen you could have what is called a hot skin condition.  Meaning that if you had an aluminum skinned rig you could receive quite a shock from your rig.

 The Polarity Tester

The Polarity Tester can also tell you if the Earth Ground (the bare copper wire) is hooked up properly.  

The Earth Ground is a separate conductor which may seem to be doing nothing but, is, in fact, a protective wire. It is there, ready to take the current away to earth ground, from the body or frame of the electrical device it is connected to, makes contact with any “hot” wire. [the 120 volts mains power is carried in two current carrying conductors called “hot” and “neutral”.] 
So, IF one of the “hot” conductors should contact the metal frame of the rig or housing of an appliance, perhaps because the appliance got damaged by being dropped from a table, or similar accident,  the third wire which is the earth ground wire, which runs directly from the housing to the grounding [or earth ground bus] in the fuse or breaker panel, will in effect cause a short circuit which should blow the fuse or trip the breaker. 
This third wire also guarantees a current path back to the electrical panel where the fuse or circuit breaker protecting that circuit is located, in the event that the hot wire should come in contact with the rig frame, but the neutral conductor should happen to have been cut or damage and become disconnected, or open. 
The idea is to guarantee that if a part of the rig, device or appliance should become “hot,” which could be fatal to anyone who then came into contact with it. That the earth ground would trip/open the circuit protection device [fuse or breaker], and turn off the flow of AC current. 

To help further in checking for unwanted or wanted electricity a good investment is the Voltage Sensor which is shown below;

 Voltage Sensor

With this probe, you do not need to touch the power line to tell if there is voltage present.  You can use this probe to find power lines behind the wall or under the floor of the Rig as well as the towing vehicle.

3.  Often times you want to know or need to know how much power something uses, especially if you keep popping a breaker or the power pedestal. The solution is Kill-A-Watt.  The unit shown below can be used to show how much power an appliance, tool, or piece of electronics is using.

 Kill-A-Watt

4. Next, let’s look at surge protectors for the various pieces of equipment in your Rig.  Surge Protectors protect only what is plugged into them and only for overvoltage surges.  Surge Protectors do not protect for under voltage or high voltages.  Shown below is a pair of good simple surge protectors;

Surge Protectors

There are Appliance Surge Protectors made just for appliances like, microwave and coffee makers

Appliance Surge Protector

AC refrigerators, freezers. 

Refrigerator/Freezer Surge Protector


These special surge protectors offer extra features like audible alarms, flashing lights, displays, etc and are to be used with just the items listed on the packaging for the one you would buy.

5.  Next is a group of power management items that will protect your entire Rig not just one item or several items in it. First is the Portable Power Management System This type of system looks at High and Low voltage protection, time delay for air conditioning compressor startup, 3-mode surge protection, reverse polarity protection, open neutral protection, open ground protection, AC frequency protection accidental 220 Volt protection. Includes an Integrated information panel, previous error code display is weather resistant and has a built-in locking bracket so it can be chained to the power pedestal at the campground to prevent theft.  The only thing this unit cannot do is flush the black water tank.  The miracle unit we are talking about is shown below.

30 Amp Portable Power Management System

These portable units come in two sizes the one above 30 amp and the one shown below 50 amp.

50 Amp Portable Power Management System

Let’s say you were involved in a lightning-caused power surge at a campground.  It is estimated you would suffer approximately $3000 worth of damage to the electrical system of your Rig along with the things plugged into it.  The features of the 50 amp unit are the same as the 30 amp unit.

Ah, but there is more!  What happens if you do not want something portable but something more permanent in the Rig? Then you have the permanent installed units which are called Fixed Power Management Systems  These units are not really DIY type of items but, they can be installed by the DIYer if care is taken during the installation.  The 30 amp models is shown below;

 30 Amp Fixed Power Management Systems

There is also a 50 amp version of the same unit as above and can be found here;  50 Amp Fixed Power Management Systems .  The features of both units are the same and are,  high and low voltage protection, time delay for air conditioning compressor start-up, 3 mode surge protection, surge trip indicator, reverse polarity protection, open neutral protection, open ground protection, AC frequency protection. Accidental 220V protection, with the remote information display panel, and unit bypass switch.  Unfortunately, this unit also does not dump the black tank.


 I hope that you now have come to the conclusion that some type of power management is needed to protect your Rig, its contents and YOU!

Severe Weather — It Happens

Posted on by

When you are asleep do you worry about this,

or maybe this

or even this?

Well I did!!

At the beginning of camping season and at the end of camping season are the most dangerous times for storms expected, or not. And if predictions are correct and this is an El Niño year then things could get really bad or not.
What is an El Niño? El Niño is an ocean-atmosphere climate phenomenon that is linked to the periodic warming of waters across the central and eastern tropical Pacific Ocean. This warming is part of the natural climate system. On average, an El Niño event occurs every 2 to 7 years and typically lasts about 9 to 18 months.
So why should you worry or even be concerned about an El Niño ? During periods of El Niño warm water builds up off the South American coast and this sends more than the normal waves of moisture into the US. These waves of moisture can, and do cause more storms, some of which are more severe than storms in a non El Niño year. This translates into more severe thunderstorms and more than normal tornado’s
While you can use your phone most of the time for weather alerts and weather radar, when you are out camping your phone may not get a signal or changing weather conditions may suddenly make your phone not work. And the basement of a 5er is not a safe place to be. So what is a person to do?

During the check-in process to get your RV site, you should ask, where do we go in case of severe weather and do you have a method of alerting the campground of approaching bad weather?
In most cases the park will have a severe weather location, like a cement block bath house or underground facilities. But most will not have a warning system. It is left up to you to know when bad weather is approaching and it is time to take cover.

So now your phone has no bars and the park has no way to tell you that a large thunderstorm is approaching your RV site. Now what are you going to do to keep you and your family safe? Buy a weather radio with built-in weather alert. Our government built, many years ago, a National Alert System to let citizens know about disasters before they happen. That was the old weather radio that went off (with its built-in siren) all the time for just about any reason (some good, mostly bad). After a lot of citizen complaints over many years a new system of alerting people was developed by the government that had a better built-in method of stopping false alerts and added text messages to each alerts displayed on a screen on the new generation of weather radios.

RadioShack SAME Weather Radio / Dual Alarm Clock / AM-FM Radio

I could go into detail on how this type of radio works but this is not a DIY Blog. This type of radio can be programed simply, thanks to SAME(Specific Area Message Encoding) technology you will only receive alerts for the locations that you have entered into the radio and you won’t have to worry about false triggers or deal with an event that has nothing to do with your area. Also some weather radios like the ones pictured (above and below) you can customize some of the alert types, so it only alerts you to the alert types that you have selected. For example, if the National Weather Service issues a thunderstorm watch and you have only thunderstorm warning selected. The radio wont alert you unless a thunderstorm warning alert is sent. Most of these radios have battery back-up and you can attach your HDTV antenna to them to extend the pick-up range of this type of weather radio. You should never leave home to go camping with out one of these special SAME radios.

RadioShack 7-Channel Handheld Weather Radio with SAME

Here is one that operates on just batteries and can be carried on the hiking trail or just outside around the campground.

No matter which one, or maybe both, you choose like a smoke detector or gas detector your RV is not complete and you are not fully protected nor safe until you have one.

Is Your Pet Safe in Your RV When You’re Gone?

Posted on by

This has been a major question with RVers traveling with their pets.  For some it was a reason not to go to a museum or sight-see some special area because there was no way to know. We have all read the horror stories of an RVer coming home to find their pet in a fight for its life or dead because of overheating in a hot RV.  Or worse yet did the power at the RV  park go off and come back on and reset everything, so that the air conditioning or heating system is not set to the right temperature?
With modern technology it should be simple and affordable to know if your pet is safe, while you are out enjoying the sights near where you are camping.  Lets look at some things that may work for you.
1. You will need an Android Smartphone that you will leave in the RV full time.  I would suggest a low cost  pay as you go Verizon phone.  The reason for Verizon is that, a Verizon Phone will work in more places than any of  the other Wireless Phone Companies. And for an RVer who is moving all the time you never know where you will be.

  • The phone needs to have bluetooth
  • Temperature Monitoring Feature (SamSung Galaxy 3 for example)
  • The phone must be rechargeable
  • You need to have both the AC and DC charger for the phone
The Verizon Moto G Prepaid Phone is an Android Smartphone that has most of the features you need.
Verizon Moto G Prepaid Phone

You will need to locate the phone where you get the best signal from Verizon and that is also near an AC power outlet.  You will also need to download from the Google Play Store an Application called
“Temperature Surveillance” located here Temp Surveillance .  The way this system works is the phone monitors your RV with your Android Smartphone. The day to day phone you normally carry with you will get an text message (SMS) if the RV  gets too hot, too cold or if a power failure occurs. The text message you will receive will  contain information about the RVs temperature and if there is a power failure or not in the RV.  All you have to do is tell the App the temperature limits high, low, and the telephone number where you want to receive the text alarms. Then just leave the RV Android phone plugged into the AC  in the space you want to monitor and you are done.

Positive: Simplest and cheapest method to monitor RV Temperature.
Negative: May not work with all cheap smartphones.
2. You will still need the Verizon phone above.  However for those smartphones that can not use the Temp Surveillance App here is another choice. The Elertus™ sensor monitors and sends alerts to your phone the instant an important door is opened/closed, a light is turned on/off, if temperature or humidity levels hit critical trigger points, or if the sensor is moved. In this case the Verizon RV Smartphone will have to be used as a Hotspot.  The Elertus will call your daily carried phone and report what the problem is.  This gives you time to get back to the RV and correct the problem.
 Some of the features of the Elertus are listed below.
  • 100% wireless, place it anywhere
  • No fees or subscriptions!
  • connects via wifi
  • temperature (-20°F to 150°F)
  • humidity (0 – 100%)
  • movement (accelerometer)
  • door sensor (open/close)
  • light sensor (on/off)
  • connection loss (wifi)
  • battery (0 – 100%)
  • free mobile app
  • access from anywhere
  • manage multiple sensors (ten per account)
  • alerts multiple users

To get more information on the Elertus system go here Elertus System of Remote Sensing

Here again the sensor sends information to you about the temperature in the RV and if power has failed.
3.  Another system (we are getting pricey folks) is Temperature Alert .  This unit would use the RV Wireless Phone as a HotSpot and send you text messages about the temperatures in your RV.
Temperature Alert Wi-Fi

The system does work well, but for some of us, it is a bit pricey.
The above unit is Temperature Alert Wi-Fi here is the Temperature Alert Cellular version of the same unit.

Temperature Alert Cellular

There are two more systems coming online later this fall
4.  The Wimoto THR001 Thermo Bluetooth Smart Thermometer Sensor.  This sensor will send the temperature information by Bluetooth to a device that will post the information to the Web using your RV Phone as a HotSpot.  Some of the features are listed below the picture.  This unit will be available later this Summer or early next Fall.

Wimoto THR001 Thermo Bluetooth Smart Thermometer Sensor

Some of the features are listed below;

  • Both infrared non-contact and needle probe thermometer in one. Infrared range 0 to 212 Fahrenheit. Probe range is -50 to 500 Fahrenheit.
  • Relays information to Bluetooth 4.0 SMART Ready devices such as iPhone 4S/5/5C/5S and certain Android phones and tablets with up to 100ft range
  • Acts as a datalogger when no smartphone or tablet in range and records information periodically for up to a month at a time.
  • Runs for 1-3 years on a single battery (user changeable) and weather resistant
  • Integrates with Wimoto Cloud Cube for real-time, always-on updates via the Internet

The thermometer sensor will send its information to the Wimoto Cloud Cube which will send the information to the internet and then be passed on to your everyday carried Smartphone.

Here is what the company said about the Cloud Cube; “Connects Wimoto Bluetooth SMART sensors to the Wimoto cloud service via Wifi. Extends the range of Wimoto sensors so that can be accessed from anywhere you have Internet connectivity.”  Here is a link to the Wimoto Cloud Cube that will be available late Summer 2014 or early Fall 2014.These are some of the best ideas currently available or that will be available soon.  It is important for all pet owners to enjoy RVing and that can be difficult when you are afraid to leave your pet behind in your Rig and strike out for adventure.

How hot is it in your Rig?  Now you will know.

Until next time.
