Sunbank SR609C Solar Controller

Description

120-240 volt solar controller is a thermostat that displays the temperature inside the Sunbank tank and powers the 240V (40G and 80G) auxiliary heating element. The controller comes with 150 ft sensor wire so that it can be mounted inside the house while monitoring the temperature inside the solar water heater. This controller also has a relay through which a pump can be powered to do both overheat protection and freeze protection. See the Sunbank Recirculation Valve and Pump listing for more information about this.

Requires a dedicated circuit if also powering the element.

Product Warranty

SunBank Product Warranty

We want you to enjoy free hot water for a long time and that is why we offer a 10 Year Warranty for manufacturer’s defects on our evacuated tube collectors and a 1 year warranty on all other components of the system.

We understand that going solar is a big investment and we want to work with you to make sure that you are happy with your investment, including a reduced price for replacement components that are out of warranty. Solar water heaters experience incredibly harsh and varying conditions. The combination of extremely hot water, pressure changes, mineral content, and chemicals are things that wreak havoc on a water heater. And these conditions vary in every municipality and well water system across the country. This is why every Sunbank tank comes with a magnesium anode and we recommend that it is checked one year after installation and that future changes are based on how much of the anode remains after one year. For more information about sacrificial anodes read this.

Solar water heaters, with their widely varying temperatures, also experience much more pressure fluctuation than conventional water heaters. Because of this, we recommend that you install an expansion tank when installing your Sunbank. Especially if you also have a check valve or “backflow preventer” installed in your system.

We make the Sunbank out of the best components that we can. That said, nothing lasts forever. We look forward to working with you when your Sunbank is working great. And if it isn’t, we looking forward to working with you to make it better and to help you to continue to harvest that free energy from the sun.

Product FAQs

Do I need to keep my conventional water heater?

No! Our system comes with a backup heating element so you can use it as your only water heater. If you do this, you will also need either our WiFi or hard wired controller. However, if you live in a cold climate, want more hot water capacity, or prefer to keep using gas as a backup, then you may want to install the Sunbank as a pre-heater to your conventional water heater.

Can I use this with a tankless or on demand water heater?

Absolutely! That is a very efficient installation scenario because you avoid the standby losses of a conventional tank water heater. Most all modern tankless water heaters accept pre-heated water, or are “solar ready,” but check with the manufacturer before installation so that it doesn’t void your tankless water heater warranty. They can be sensitive systems, and sometimes manufacturers will want to make sure your water is not too hard, also, in order to honor their warranty.
It’s worth mentioning that when comparing a tankless system to a solar water heater, from an economical perspective there is almost no comparison. Tankless water heaters are relatively expensive to install, so while they may cost the same as a solar water heater they still burn gas or consume electricity and are 75% less efficient than a solar water heater.

What if I'm on well water or have hard water?

If you’re on a well, our advise is to install a whole house reverse osmosis filtration system before installing a Sunbank. High mineral content water causes corrosion and will shorten the life of the tank. Installing a filter will help your entire plumbing system last longer.

Can I put in a second, longer magnesium anode?

Yes! If you have high mineral content water, or just want to protect your tank and not change your anode as frequently, this is a good idea. For our newer systems that have the side port on the bottom of the side of the tank (not the middle), you can use a 3/4″ brass coupling installed on the cold side port to install a 42″ rigid anode. For our older models or our newer models, you can install a flexible 42″ anode, also available at most hardware stores.

What if I'm off grid?

Then you’ve found the right system. This system works perfectly as an off grid solar water heater. Our system requires 0 kWh of electricity to function and you can use the system whenever you have hot water. Or, if you want to always have hot water or a place to store your excess electricity production, we have a 120V element option that you can use for that.

What if I use a lot of hot water at night?

That’s fine. The Sunbank solar water heater is installed in such a way that you always have hot water; either as a pre-heater to your existing water heater or as a stand-alone system with a backup electric heating element installed in the Sunbank. And the Sunbank tank is very well insulated. If you use a lot of hot water at night then you will use the heat stored in the Sunbank and then the backup heater will kick in for any hot water consumed in excess of the amount stored.

What happens to the temperature when I take a shower?

The Sunbank typically stays in the 100F-160F temperature range. Your Sunbank may be at 140 degrees when you take a 10 minute shower at 2 gallons per minute. That means you have used 20 gallons of hot water thus introducing 20 gallons of 60 degree ground water into your Sunbank tank. For an 80 gallon tank that means you have used 1/4 of the heat which would drop the temperature of the tank by 20 degrees (140-60 X .25) to 120F. In reality you would be using less than 2 GPM of hot water because you would mix down 140 degree water to 120 so that it doesn’t scald you. You would actually use 15% less hot water or 1.71gpm (140/120 X 2) and therefore be left with 123F in the tank. Any water temperature over ground water temperature means gas or electricity savings. And when your Sunbank is over your backup temperature set point you are not using any fossil fuel to heat that water.

This is the Ferrari of Sauna. The quality, craftsmanship, and durability of this product is TOP NOTCH. Paired with the Harvia Heater, it is an exceptional sauna. The look is so modern and chic. Easy to clean, looks great everywhere. And the tech setup for the Harvia is so simple, I was up and running in 5 minutes. Could not recommend this more. Also. If you really want you can fit more than 3 it is quite spacious. 10/10

Great tub, easy setup

It’s amazing that this is a portable hot tub. It was easy to setup and looks like a permanent hot tub! It took about 2 days to heat to 104. We live in a place that snows so we added extra insulation to the panels and extra ground cover.

The jets are not super strong so I would have preferred getting the Tribeca which is less expensive and comes without jets. It does have bubbles.

But overall a great product, first of its kind I believe.

Outdoor Sauna CL4G Cube

We pre ordered this sauna. It’s all put together with the help of a contractor. It took 2 guys 2 full days. We are very pleased with the sauna all together. It’s clearly top of the line. The sauna fits 2. Maybe 3 if you want to squeeze. The sauna fits well in our backyard. It adds a sense of tranquility to our favorite space. Off grid was extremely easy to work with. It was clear they put the customer first!

Love the machine!

I absolutely love the machine. I use it everyday. I was disappointed to see some paint scratches on it when it arrived. However, after some contact with their Customer Service department we were able to sort it out. I highly recommend getting a freeze dryer!

Ideal Power station AC180P

I was in the market for a power station that has enough power and capacity to power my fridge and some essential appliances at my house. I come upon this power station from OffGrid living Solutions and I have been using it since. It has enough power for a longer period of time and has multiple ways to charge (AC/Solar Panels). This station is perfect in size and comes at an affordable price. Thank you OffGrid Living team and Bluetti ....

Such a quality sauna heater

My wife and I love this heater for our sauna. We love the automatic feature of the heater where it turns off once the optimal heat level is reached. Sturdy and durable product, especially for anyone looking to install one on their saunas

Anker Solix F2000 with Solar Panels

This unit is perfect for power outages! We were looking for a unit that can power our essentials during outages like TV, fridge, microwave, lights, and our wifi. This unit can also act as a UPS so nothin shuts off when the power goes down. I like to connect my solar panels to the station when it looks like the outage will be extended. GET THIS STATION! YOU WILL NOT BE DISAPPOINTED!

Great Solar Generator!

System performs well in powering things and amazing hardware build quality. One issue I have with AC200Max is that I cannot control it remotely via the internet so when it shuts down due to depletion of battery and turns on again after solar hits the panels, I have no way of turning the AC output on remotely. The other thing is that it lacks portable wheels, carrying this thing is a chore. Other than that, this is a pretty good unit and for those who don't need to have the remote control, this could be your solar generator. OLS team was good and respondant on all of my questions. Overall, this solar generator offers excellent power output and capacity to run nearly anytthing you plug into it.

Great product and keeps you cool during trips

Wave 2 is a quiet portable air conditioner, even when you put in on Max mode. I purchase this is for my van for during the hot days during camping. Love that I can carry this to around with ease. I plan to use the heating feature once it gets colder. I'm happy with my purchase and can't wait to see how it functions on the heating side.

Works great!

The AC200 Max and B230 work Great! So much that I added another B230 on the next order. This set up will be used for my farm in the summer and as a emergency back up in my home when it gets cold. Great product! Thx Bluetti and OffGrid Living Solutions

A Game-Changing System

I recently invested in the EcoFlow Delta Pro and I am beyond impressed with its performance.

Setting up the Delta Pro was a breeze. The user-friendly interface and informative display made it easy to monitor power consumption and remaining battery life. Plus, the variety of charging options means I can harness energy from solar panels, car chargers, and regular outlets, making it perfect for both everyday use and outdoor adventures. One of the standout features for me is its portability. Despite its robust power capacity, the Delta Pro is surprisingly lightweight and compact, allowing me to take it on camping trips, picnics, and even to power my work tools at remote job sites.

The customer service I received from EcoFlow was exceptional. They promptly answered my questions and provided helpful insights into maximizing the Delta Pro's capabilities. Overall, I would highly recommend this portable power station.

Perfect Hydroponic Garden

Great Customer Service Team. The first batch of seeds are already growing. Looking forward to fresh greens. The only negative about this garden is that it was difficult to set up as the manual instructions were unclear
