Hi Everyone. Well, after 15 years the RV-Dreams Community Forum is coming to an end. Since it began in August 2005, we've had 58 Million page views, 124,000 posts, and we've spent about $15,000 to keep this valuable resource for RVers free and open. But since we are now off the road and have settled down for the next chapter of our lives, we are taking the Forum down effective June 30, 2021. It has been a tough decision, but it is now time.
We want to thank all of our members for their participation and input over the years, and we want to especially thank those that have acted as Moderators for us during our amazing journey living and traveling in our RV and growing the RV-Dreams Family. We will be forever proud to have been founders of this Forum and to have been supported by such a wonderful community. Thank you all!!
I have a 30 amp system on my boat. The boat is plugged in April 1st thru October 30th. During the mid summer with all airconditioners running etc my voltage would drop to 95 and less. I had a voltage booster installed in my dock box which is working great. Now however, during the spring and fall when there is less power consumtion on the dock, my voltage can be as high as 135-140. I have looked at the Progressive EMS-HW30 and the Surge Guard Voltage regulator. The Surge Guard boosts power when needed and offers no protection for high voltage. The Progressive EMS-HW30 will protect either high or low voltage. If too high, it will shut down all power until a less than 132Volts is found with a delay and then turn back on. That is fine when we are there but we only use the boat on weekends. During the week the voltage may never drop to 132volts so it never would turn back on. The problem is that we leave our refridgerator running and loaded food and we leave the battery charger running. We can't turn off either unless we remove all the food and hope that the batteries can handle the bilge pumps for a week.
Is there any type of a true voltage regulator that will boost when needed and stepdown voltage when needed.
The simple answer is yes, most definitely.However, these are not something you would find at a “Camping World.” These are active, not passive devices. We used many of them on our TV mobile units and high power TV transmitters. Most all like kind operations use them.They have a very wide voltage input range.However, IMO, this is not a do it yourself project.There are some parameters that are important to the installation and I still would keep the HW-30 in line after this regulator.
I have no idea who around you would be qualified to do this work. But IMO you need a professional to spec this device out and install it based specifically on your situation.A local licensed electrician at the least.But you may have to do a bit more searching for someone other than a “house” electrician.It’s not all that complicated, but it is a bit more specialized than wiring a home. Its the device selection, not the installation that requires this knowledge.
