Description
Can you run a house furnace off a 48 volt battery? Yes. Here I show you have a 48v LiFePO4 server rack battery can run your home furnace. I'm using the Growatt 3000 SPF 3000TL LVM-ES inverter connected to a RUIXU 48V LFP or LiFePO4 server rack battery for this test. Earlier I installed a Generator Plug on my Furnace so I can run the furnace off a generator or a furnace( • backup FURNACE PLUG - ... )

You stated that there was a link to the solar panels in the description. Where is it?
Recent subscriber.
Really great content. It helps me develop a mental plan of how to address power needs of current appliances and load needs. Also helps me plan a path of replacement appliances or additions and in what order.
I've watched several older vids and the comment section is helpful & polite. Several comments expressed the idea to have several smaller systems. Each dedicated to particular needs (refrig, lights, security etc). It was a real eye opener. Im embarrassed to say but ive been interested in solar for 15 years+ and I'd never considered doing that. My mindset had been simply size up the # of panels, get new cables, larger inverter etc etc.
Thanks for creating the channel. Its very practical and relateable.
Thank you. I also hadn't considered many small units until people mention that in the comments. Pretty good idea actually
I have the same growatt inverter and find the % of battery left can be misleading. If you compare the battery voltage when the Growatt says 50% to a typical LifePO4 charge curve, I think you will find that the battery is lower than you think. I have my doubts that it would go another 24 hours at 49%. You should actually test it.
That's interesting. With my setup I have closed loop communication so the battery is telling the growatt how much power is left. I have set mine up so it won't start beeping at 30% battery life. I think the default setting is it beeps at 30% and then turns off at 25%. I have mine set so I can go all the way down to 5%
The first step in going solar is to purchase efficient appliances. I have similar goals as you but before powering a inefficient system, Im researching what is possible to convert my traditional furnace to dc. I am looking for a dc blower motor, the transformer shouldnt be too hard. As for a fridge, some rare fridges use r134, Id like to retrofit a regular fridge to a 24 volt dc compressor. Then run these test. I wonder if bypassing ac invertion will eliminate the need for extra batteries/panels...
Solid battery for a good price, wow 👍
I did a test with my furnace. I also have a nest smart thermostat that records how long the furnace is actually blowing heat. I tested it on a somewhat cold night (I live in San Diego) and the furnace was on for 3 hours over the night and morning. I guess my point is when doing these tests its nice to have a smart thermostat that records the time that the furnace is on.
Nice!
Great test. I am wondering how long gas service would be available during a longer outage like what Texas dealt with a few years ago.
It's a good question. As I recall they still had gasoline during that Texas outage but I could be wrong.
Yes, we still had gasoline. We didn't run out where I was at
Great test, I got the Eg4 6000xp inverter…for a complete novice it’s been quite the adventure to get to work correctly…
Nice. I've got one in the mail. Is yours set up yet?
Yep, just working out the kinks of charging predictably from the grid for the moment, solar hook up soon weather permitting, I made a few vids with updates.
@@ScottieBMan cool. I'll check it out!
Yes I got a 6000xp too. Very nice unit! It’s running my water well house perfectly with three 445w panels like a boss. Make sure you do a firmware update on the lifepower batteries to get the communication to work. That took a while to figure out
@stevezark2152 dang, it looks like I'm going to have to do that. Do I have to get a special communication cable? Never done a update before on these batteries.
Great test, Ray. Thanks for sharing. What was the ambient temperature when you took the test?
An alternative between running a generator the whole time and buying more solar panels, is the "EG4 Chargeverter"
You can basically hook it up to any generator, charger up your battery in like 1-2h or so without wasting bunch of gas and run the furnace for another couple days.
I have a 7KW whole house generator that I will be converting, so it only chargers my battery when the grid is down AND my panels are not keeping up with the demand.
It's currently for $399 at SS. Would love to see you test it in detail. Many thanks and God bless.
Edit: Since you ran the furnace from the battery, did you have any issue with neutral-ground bonding?
Thanks, it was between 30 and 40 degrees fahrenheit. Pretty warm. Thanks for recommending that product I might have to check it out. I had to make the ground neutral Bond. Using a bonding plug.
Can that specific Growatt be "stacked" (not sure if that is the correct word) with another identical unit to supply 240VAC so both sides of your electrical panel could be powered at the same time?
Yup
Thank you for putting this video out for us. I just have a question about the pinout for your communication cable. I have 2 Growatt SPF3000LT LVM-V48P and I cannot get them to communicate Setting Option 05 to L!I and Option 36 to L52. I just get Error 04 and error 20 no communication. From what I read in the RUIXU manual CAN is just Pin 4 & 5 on battery side to pin 4&5 on inverter side. Growatt support says that the communication protocols are the same on SPF3000-ES as the SPF3000LT LVM48-P but no matter what I try I cannot get it to communicate with the Battery BMS.
Hmmm. You could reach out to Ruixu support on their Facebook page. That's what I'd do.
@@diySolarPowerFunWithRay
Thank you, I have been in communication with both Growatt and Ruixu. No resolution so far.
I would personally buy a dual fuel inverter generator with the $500. I've been in scenarios where I had to use my portable generator to charge my power banks. One time I could not start it with gasoline even after routine maintenance and switched it over to propane and started. Anyway you only run the generator for the amount of time it needs to charge the battery. In my opinion totally worth it especially during winters where the peak solar hours are greatly reduced if any available at all for days. Great video btw.
Thanks, I currently do not own a generator. Good info
May also be helpful to mention that this is a gas furnace and not an electric furnace in the title of the video. Looks like electric furnaces use 10 to 15 KW hours so that 5 KW battery would not be able to run it for even an hour.
Good point.
My system is still being built in a backyard shed so it sits on standby during the week as I can only get back to it on the weekends. I have 4 packs for a total of 19.2 kWh. I found out that each pack can only detect >0.5A so I have to draw at least continuously about 100-200 watts for the SOC on the batteries to be accurate. The pack dies a few times at >90% SOC before I caught on!.... wont have this problem once I have more continues draw devices.
Oh, interesting. I will have to watch for that. That's kind of annoying the BMS won't track that better.
I'm ignorant on this stuff, but could you just add a second battery to this system to double the time it would run? Slightly more expensive than more panels, but seems less of a hassle.
You definitely can. There is a small Communication cable that comes with your battery. It's basically just a short ethernet cable. You simply use that connection cable between the 2 batteries and then on your second battery or non Master battery You put all the dip switches down. And then the communication will work. You can follow this same procedure for a third or fourth or 5th or sixth battery. Any non Master battery will have all of the dip switches down. Hope that makes sense.
More fridge/freezer solar content 🙏
Any specific tests you would be interested in?
@@diySolarPowerFunWithRay try to build the cheapest system that can run a full size fridge.
Are full size 12vdc fridges worth it? Chest fridge/freezer with no defrost cycle vs linear inverter fridge.
Great Video, by the way, the Gas furnace missing dripping leg ..
Well, that is super helpful. Thanks for pointing that out. Didn't even know that was a thing
Also you should have a shutoff valve prior to that but I assume u have one close reach.
Be careful connecting to the grid the growatt ES is a European version so you will have 2 grounds and that isn't crazy safe, I would probably not connect it to the US grid.
I believe this one is the US version.
Why didn't you go with your now familiar EG4 battery like in the trailer?
I'm thinking about using this one because it is smaller in size, it has a better server rack cabinet, and it is priced better. I'm still testing out their support and some other things before I proceed.
@@diySolarPowerFunWithRay Got it. I sent you some links. One is to another YT provider that did his trailer as well but went all component, not all in one. Also I sent the Signature Solar link for using. a mini split with solar (to replace your trailer roof A/C) I learned from the other guy but he didn't do the hybrid MS.
@@benkanobe7500 cool, I will check them out. I definitely want a mini split on my fifth wheel. But after the frame cracked in Mexico it might be totaled. So it might be time for new RV build. I'm speaking with the insurance company now
@@diySolarPowerFunWithRay If they total it, buy it back from the insurance company and take it to a fabricator that will make it stronger than anything you can purchase.
a other believer t look for something extra the use on the name plate
will not due for him and the battery amps x volts as energy also not.
do you realy think people care if you take 1 watt less or more out.
I'm still testing these out. I might get a full rack of these but we will see
I know one thing howlong the chinese is not a good runner
I believe most of the cells come from china.
