*Absolutely perfect for what we use . **Generater.Systems** for Our 500wt power station! Love it!!!!*
Solar Generators can be anywhere from $100 to $5000 - there are many sizes and options. Thanks for watching
Very good and helpful presentation.
I'm sure it's not easy matching what's really needed with the best, cost-effective system. This goes a long way to putting a practical face on the question.
Thanks!
Glad it was helpful! Thank you for watching and leaving a nice comment.
I appreciate the high level overview with some dollar estimates. This level of info has been hard to find (particularly ballpark dollar amounts). One thing- when I saw Generac in the title I thought you were going to include Generac generator as an input option.
I was sold what was termed a 'hybrid' backup system which falls under your partial backup category. It uses 1 Enphase 3 battery, but also has a 10Kwh Generac NG generator to go with the Enphase battery backup. The primary source of power during a grid-down scenario is the battery. If the required loads is greater than the 3Kwh battery can handle, the generator kicks on to both supply more power for the critical loads and to also recharge the Enphase battery.
The 10Kwh generator could handle more than I have setup for critical loads, but cannot handle an Electric stove or AC so I just chose lower power items such as what you mentioned including the circuit the microwave and fridge are on so we at least have food and a way to cook things.
The Enphase smart switch allows for connection of the generator. It was more cost effective than more Enphase batteries at the time (couple years ago). Unfortunately it took until last December for Enphase to release the production software firmware upgrade to allow the generator to work seamlessly with the rest of the system. You may want to consider adding that option as it may be more cost effective to have a higher capacity generator installed vs so many batteries.
Best explaination yet, thank you.
Thank you very much - you are v kind. Thanks for watching
Great overview. Appreciate the cost data too. 🙂
Much appreciated!
Glad it was helpful! Thanks for watching
Excellent and very helpful. Thanks!
Thank you very much, Art. Please subscribe for new videos too.
Glad to see Generac is providing a viable 3rd option. I have a Powerwall currently but Tesla isn’t interested in generator integration. So any expansion will be with Enphase, Generac, or a custom system.
That is good to know. So even the new Tesla Powerwall +'s are not coming with generator integration. Thanks for watching
Thank you for this summary. This confirms the proposal for 3 Enphase IQ10s for my RI home. I have baseboard electric heat, electric hot water and a mini-split and an EV charger. With all of these 220v circuits I’m using a Lumin panel to shed loads. The 3 panels will not satisfy 100% heating load in the winter but it is a seasonal home with minimal usage in the coldest months. National Grid has a battery capacity purchase program that allows me to sell power back to the utility during peak demand so the system will pay back the investment in about 10 years. This is not great “investment returns” but it beats the $0 payback on a higher maintenance and polluting generator.
Absolutely the right decision - We should phase out Generators slowly and move to an all-battery mode. But, we do have to get our battery recycling ship in order. The planet thanks you. And thanks for watching.
@@MySolarHomeUSA I also think the government should mandate 2-way charging of all EVs with a smart transfer switch/charger allowing the utilities to access our generous EV storage at peak periods. I’m investing nearly $1000 per kw of storage when I have 70kw sitting in my Tesla that would be useful in an outage.
@@Paul-GrnHil Yes - what kind of Tesla do you have - it might have more than 70kwh of battery parked inside it. We will get there sooner than later. Just like the computers are all networked, all the batteries will be too. And someday over the air charging of our devices.
I have a Model 3 and a Model Y. I got a lot of battery capacity.
Thanks for the overview John. Does this mean that for EV charging the Whole home backup is the way to go? Also curious to know which one of these would start to provide me relief from electric utility bills. Thanks
Thanks for watching. Whole home backup would be the way to go if you plan on EV charging. However, EV charging is one of the most intensive energy applications and it typically should not be done from batteries. Re reducing your electric bill - that would need solar panels. If you would like a quote - you could send me an electric bill to jon@mysolarhome.us
Thanks for the very helpful layout of options and pricing. Is it correct to assume that these are exclusive of any rebates from the government?
Yes that is correct. The rebates are 30% tax credit on those prices. Please send me a recent electric bill to jon@mysolarhome.us if you are looking for a quote for solar and batteries. Thanks for watching
If you were considering having solar installed, please think carefully before signing with Soleria Solar Or or Enphase. My system has been installed since September 9 months later and it still does not work. They've been out here and worked on it several times and it still doesn't work. Now I get some of the highest electric bills I've ever had and and a loan that I'm making payments... They don't ask for phone calls or return messages left.. I don't know if they're messing with me or just Incompetent......
Looks like your installer Soleria Solar has not done a correct install. Enphase is not the problem - your installer has messed up. I hope they resolve it soon for you. Best of Luck.
Hello, I got quotes for add 1 battery 10T to my solar system for $14K to $22K but they not be able to list out the components included. I want to make sure the low end includes all the Enphasis Essemble needed for partial battery backup. What is included on your pricing? One system Load controller and Subpanel also?
Hi. My install partners install solar + batteries. They dont do only batteries. A 10kwh Enphase should be around 15k all installed with subpanel, load controller and everything else included other than town permits. Thank you for watching.
I received a quote for a solar system with two enphase batteries.
10KWh Enphase Encharge Battery System
6KWh Enphase Encharge Battery
With these two batteries, what can be run in an emergency? And what will be the back up hours?
Hi Luis - so you have a total of how many kwh in batteries - perhaps this is better discussed over an email. My email is jon@mysolarhome.us - and let me know where you are located and how much you are paying, maybe share your existing quote and - I might be able to get you a batter deal. Thanks for watching.
You can’t achieve whole home back up with just 3 enphase encharge 10s? What can 3 enphase Encharge 10s achieve?
With 3 Enphase Encharge 10's you have 30 kwh of energy storage. That will be be enough to give you whole-home backup but you will have to regulate the usage of your AC / Water Heating /Electric Range use. You will be able to use one of the 240 volt appliances at one time and you should not expect to use it for more than 4 to 5 hours at max. If you are looking for a quote - do email a recent electric bill to me at jon@mysolarhome.us. Thanks
Will prices of batteries come down. I think the idea of at least one enphase 3kw battery makes sense for me on a limited budget considering installing two heat pumps, and the solar panels etc................. I didnt win the powerball! ;-) The reason I like this option is that it will create at least the independent internal network so that I could use available sunlight in the solar panels during the day - I am getting IQ8 inverters. I have a small portable generator gas/propane champion, run separately from anything else, to cover off lights, fridges, computers during the night. Think of it as a lite way of ensuring no shock on power outage and giving one time to gracefully switch to the portable especially doing so not in the dark.
In summary, I think I will end up with at least 2 10Kw batteries but I think it will be cheaper to wait.
Alex : I am completely in agreement. With a 3kwh you are good for your internet, kitchen and lights. And you are ready to upgrade when the prices go down. I would love to quote for your project. Please send me a recent electric bill, to jon@mysolarhome.us and I will work out some numbers with the 3kwh. Thanks for watching.
The problem as I see it is, that if my home panel includes an 80A circuit breaker, I need the inverter to output at least 64A to comply with the NEC 710.15. This would require 4 IQ Battery 10Ts, but my whole house only uses about 65kWh per day, and outages are rare, so I don't need 40.2kWh of batteries. I only want to offset my nightly consumption which requires less than half of that capacity. These systems don't give you a choice of sizing the inverter separately from the battery. The ratio of inverter size to battery size is fixed. Nobody ever seems to mention this. Using this system, I'm buying battery capacity I don't need in order to size the inverter to what the code requires.
Todd - I am not an expert , my 2 cents is : the code does not have a requirement of "at least 64 amps" - it might have a requirement of current not to exceed 64 amps - and that means installing smaller batteries is not a problem. If you would like, I could work out a quote for you - you could email a recent electric bill to me at jon@mysolarhome.us . I see no problems to installing small batteries - I have dozens of customers who bought the 3kwh Enphase battery to just run their internet and lights - batteries are expensive and the 3kwh is the lease expensive option. Thanks for watching
@@MySolarHomeUSA NEC 710.15 has a requirement that the inverter must supply equal or greater power than the largest load on the system. If the largest load on the system is more than these batteries can provide, you need to add more batteries. You can't simply add more inverters.
@@ToddDesiato That may be a requirement for the inverters on the Solar System; those are usually different from the inverters for the batteries unless you have a combined inverter. What I know from many installations is that you don't need to add batteries to meet NEC code - the 3kwh single battery installation is one of the most popular choices because it is the cheapest.
@@MySolarHomeUSA If you took the Enphase storage certification training, they teach you that for an IQ Battery 3T, their smallest one, the Largest circuit breaker allowable in the essential loads sub-panel is 6A. Eaton, SquareD, and GE do not make a 6A, AFCI breaker.
@@ToddDesiato This is looking to be beyond my pay grade: all I know is that I have had over 11 installations of the 3kwh Enphase Batteries done - so I believe there must be a workaround without having to buy a lot of batteries to meet code. Best of Luck with your project and I really appreciate you trying to make me understand .. but I am afraid I am lost.
Yes akb Tesla 🔋⚡💡👍
You need to tell people if they have a blackout these won’t work if their system is grid tied because the inverter needs current all the time. Your solar system won’t generate electricity even when the sun is out during a blackout unless you have a switch to disconnect it from the grid or you AC couple or DC couple it to the inverter.
Hi Chris - I do mention that in my videos on Solar Panels - I missed out on this one. Thanks for watching and your comment.
This video completely missed out on the supply side issues of these batteries. For most of them, you cannot have a supply side solar that outputs more energy than these batteries are capable of charging with. An example is: if your battery can only charge at a max input of 5kW then your solar panels cannot output more than 5kW or the batteries will shut off the solar generation during a grid outage any time your panels output more than 5kW.
For my house, I found that I never exceed 2.5kW usage at peak and 5kWh of storage for ALL of my 110v circuits including my lights, internet, television, microwave, dishwasher, clothes washer, garage door opener, etc. when using everything as normal during a grid outage between sunset and sunrise the next day. Anything over that is needed for the 240v circuits in my home with the electric heat pump air conditioner/heater, electric clothes dryer and the electric water heater by far being the most consumption and using more than 90% of the all the energy my house uses on a daily basis. I switched the water heater to a heat pump water heater to cut its usage dramatically. When the grid is down, I adjust my thermostat up or down based on how much energy I have saved in my batteries which gives me whole home backup for as long as I need it but still allows me to use heating and cooling to some level based on how much energy I have available.
Steve, cant thank you enough for that real world example. Super to know. What kind of panels and batteries do you have? My understanding is that Enphase usually does not have the supply problem since the IQ controller automatically controls input energy into the batteries from the panels.
@@MySolarHomeUSA I have an older Enphase solar system with IQ6+ microinverters that is rated at 14.5kW. I routinely see more than 12kW being generated out of this system in the peak of the day. Enphase systems with Enphase batteries can modulate the solar output but they do not do this well when mixed with other technologies. I would need Enphase batteries which were not available when I put my system in. I have 3 Tesla PowerWall 2 batteries with 40.5kWh of storage, 15kW of sustained max use or charge to/from the batteries, 21kW of burst usage for up to 10 seconds from the batteries, and a Tesla gateway that manages the system.
The batteries shut off the solar inverters when you are off grid and they are full or if they need to for any other reason by changing the hertz from the standard in your part of the world (60hz here) to a higher number such as 65hz or 66hz. This causes any modern grid-tied inverter to temporarily stop operating as the power is out of specifications for them until they see the power back into proper specifications for a few minutes.
$5000 I can have 15kwh in a rack.
Sure you can. Controlling the battery and solar to work in tandem and also automatically islanding the system during an outage requires a lot of electronics. The big players package and charge a lot. If you have the DIY skills - building a system from scratch is much cheaper. But, most folks dont have the chops to do that. Thanks for watching.
@@MySolarHomeUSA I didn't do it myself. But I bought the panels batteries and suitable grid tie inverter/charge controllers. All UL Listed. I just paid for them to handle the installation and help with the permitting process. Still saved myself 25%
@@davefroman4700 Congratulations. I am glad the hard part is over. Watch out for maintenance and warranty issues. That might be the only trouble. Thanks for sharing your experience.
??????? ☝️
I am not sure what you are referring to. My video was to help size the battery for your home. Would a 10kwh work better or a 20kwh etc. So the title, how many tesla batteries or generac batteries do you need .. etc. I apologise if it was confusing.
