What kind of space do I need to dedicate to a Hub install?

A space that is 3.5’ Wide, 3’ Deep and 8’ High. The space should allow for 36” in front of the device for service access.

What kind of alternative energy options does the Hub handle?

With the addition of our Solar Box 10 (SBX 10), the Hub can now handle up to 10kW of power from solar panels. That power can be used to recharge the batteries for extended run time or to power the load when the batteries are fully charged.

The Hub will also do the same for generators, without needing the SBX 10.

The Hub does not currently handle wind turbines.

What kind of batteries does the Hub use?

The Hub currently uses Advanced Lead Acid batteries.

A key point to the lead-acid batteries is that they are 99% recyclable, while lithium-ion batteries are recycled at a rate of 5%.

How long will my whole house run if they buy a certain size battery?

For an existing property, the easiest way to answer the question is to get a copy of 12 months (accounts for seasonal differences) of utility bills. Take the number of kWh for the highest month, then divide by the number of billing days. Use that number to divide into the size of battery capcity needed. That result will be the number of hours and/or days of backup.

The next question you need to answer for the client is how large an inverter is necessary to power the house. An inverter converts DC from the batteries to AC which will power the house. A relatively safe estimate for the necessary inverter size is to take the size of the service, measured in amps, multiply that number by 240 volts (voltage fed to most houses). That number will give you the inverter size necessary to power the house if the service is fully utilized. Since a home rarely, if ever, fully utilizes the available power, the inverter can be cut to approximately half the previous number.

What kind of support does RoseWater offer?

We, at Rosewater, will guide you through the process from beginning to the end of the project, including sizing, delivering, and installing the Hub, as well as working with you to deliver on the client’s expectations.

If there is an outage, when will I know if the Hub is working, since I won’t notice with the zero-transfer time?

The Hub is set up to deliver whatever messages needed, including alerts to the end user, the installer and even ourselves. When the batteries begin running low the Hub will also begin beeping.

When was the first Hub installed, how long has it been around?

The first Hub was installed in 2015. Since then, as our message is heard and the need is being realized, our success has grown year after year.

What can I expect as a Dealer/Installer if I sell a client on a Hub?

Well first, you can expect way less service calls. We’ve seen some customers see more than 80% less. See here: https://rosewaterenergy.com/2019/11/04/case-study-improving-power-performance/

Secondly, you can expect the possibility of getting more business in that area. We’ve seen that many times if someone’s neighbor has one, they want it, too, as the customer with the Hub is so pleased, they share the news.

Thirdly, the overall satisfaction of the product you installed is raised, as well as a higher level of trust. Happy customers will build your business through word of mouth.

Ultimately, the Hub offers a trust in the product you install.

Why is your message that power is getting bad?

Because it is. Population density is getting higher, there is an aging infrastructure that governments don’t want to contend with in North America. Combine that with how the population is demanding more sophisticated security, control and entertainment systems, the effects of poor power quality become far more apparent and far more inconvenient. The manifestation of those problems is far more unreliability and equipment failure.

The power in my area seems fine, so why should I need/offer a Hub in my install?

When I ask people if they notice lights flickering or dimming, the television picture almost going dark or displays lighting up for apparently no reason, they all respond yes. These are all symptoms of power fluctuation and can degrade or risk losing the electronics on your residence.

We like to think of it as an iceberg. The tip of the iceberg is a power outage, we all notice that. Beneath that are many power issues that you only notice if you look for them. And all areas have them.

What’s the backstory for RoseWater Energy?

In 2012. We began our research by finding how “mission-critical” facilities ensure perfect power quality. As we went down that road, we learned that “perfect power” meant different things depending on the application. So, without getting overly technical, we took what was available and improved upon it. Beyond that, we also wanted to make sure that we created the most complete power quality solution available. So, we added protection from lightning strikes, high-capacity battery backup and the ability to charge those batteries using a renewable energy source. The Hub went through a few iterations, but the result is the RoseWater SB20. In the future as we continue to grow we will continually upgrade our product and options.

What areas do you service?

Mainly the U.S. and Canada, but anywhere that uses a supply voltage of 120V, including the Bahamas.

Which customers is the Hub perfect for?

We like to think the Hub is perfect for homes over $3 million USD, or any premises that has mission critical systems they need to protect.

What are the differences between Rosewater and Tesla of sonnen products?

In a nutshell, the other products are specifically designed to provide battery backup for a renewable energy source. None of those products are designed to improve the quality of the power feeding the residence. They provide no protection against electrical surges and sags, for example. Power quality issues are a major cause of problems in microprocessor-based equipment. In the best of circumstances, power issues only diminish the longevity of that equipment. Typically, they cause the equipment to malfunction or worse they cause outright failures. The RoseWater product is the only product, amongst those mentioned, that provides perfect power at all times. No sags or surges can ever pass our device.

More specifically, a Tesla Powerwall is capable of providing battery power to a 50-amp panel, the largest capacity sonnen product can provide is backup to an 80-amp panel, the largest LG chem will backup is to a 95-amp panel, the largest residential Blue Ion product is backup to a 160-amp panel. The RoseWater will back up a 200-amp panel.  

Here is where I become less objective, we designed the RoseWater with as few single points of failure as possible. We chose lead-acid batteries for their safety and for their recyclability. We built our cabinet to be seismic rated. We designed our product so that, should there be failure, critical components can be “hot swapped” in the field. We believe we build the most compete, highest quality, and best engineered product available.

FAQ – How do I know if my clients have power problems? Or How does my client know if he or she has power problems?

The answer that is given most often is you should hook up some kind of power monitoring device at the premise, leave it there for a few weeks and analyze the results.

I am guilty of providing the same advice.

After looking through the reports from our units in the field and noticing that power problems exist everywhere, it finally dawned on me that we have been asking the wrong question.

Have you ever noticed that clients with sophisticated control systems have more problems than clients who don’t.  The more devices a client has in a home, the more often something has to be rebooted.

The truth is virtually everyone has power problems.

The correct question is how do power problems affect my customers now and how will those problems affect my customers in the future?
