Home Battery Backup Systems Compared

when it comes to battery backup there's one name that really got people excited and that's Tesla when Elon announced the power wall in 2015 people literally went ballistic and in less than a year they updated the powerwall one to the powerwall 2 which hasn't had much of a refresh sense sure there's a hybrid model and there are some software updates that came out to allow for some extra surge power but it's fundamentally unchanged for the better part of the last six years I will admit no one else has been able to spark that same level of demand or interest in home backup as Tesla has with the Powerball but poor customer service and long installation wait times has led many homeowners to search elsewhere I've installed a lot of different battery backup systems over the last five years with each year demand increasing for more storage and more backup capabilities I've done videos on many of these Battery Systems and continue to do videos on them from the Zone in to SMA America sunnyboy storage to solar edges storage and energy Hub twin phase IQ batteries and even Q sells Q home ESS one thing has been clear the competition is fierce and one of these companies is bound to catch up to Tesla and surpass their simple powerwall design heck we might just find out in this video that it's end phase or Franklin wh or neither but we're going to find out either way by comparing these two AC coupled systems of course if you're someone that lives in our area of Southern California and you're interested in going solar or adding battery backup to your existing system then please visit us

against Enphase IQ batteries and the Tesla powerwall I really want to focus on a few key points that I feel our customers seem to be most interested in like chemistry of the battery the space needed for the equipment the storage capacity of the system its backup capabilities the scalability for the future the warranties and of course the price for those of you unfamiliar with Franklin whole home they're a relatively new company that started in 2019. they're headquartered in San Francisco and received Venture Capital funding from Sequoia Capital the Franklin was developed in-house from their from the ground up by expert Engineers with various backgrounds in electrical system designed to secure power supplies while they don't say this on their website it's clear to me this company had one goal in mind to develop a safe simplistic and reliable home battery backup solution to compete with the likes of the Tesla powerwall there's just two main components to the Franklin the battery called an a power and the automatic transfer switch called the a gate when you compare this to say an end phase system and a Tesla powerwall well end phase has two battery variations the iq3 and the iq10 they have the ATS which is their IQ you System Controller and you have the IQ combiner box for the micro inverters and the monitoring Tesla technically has two batteries the powerwall plus which is a hybrid and the powerwall 2 which is a standalone AC coupled and their transfer switch is just called the gateway for this video we're really only going to be comparing the powerwall 2 with Enphase and Franklin when you compare the battery chemistry among these manufacturers you find Tesla being the odd duck still using nmc nickel magnesium Cobalt compared to end phase and Franklin who are both using lfp lithium iron phosphate this is important to note because with recent changes to the electrical code batteries that do not have ul9548 testing will have to be installed three feet apart both Enphase and Franklin thankfully have the UL 9540a testing certification which means you can actually install end-phase IQ batteries six inches apart and Franklin a Power Batteries 12 inches apart so much more compact design it's important to note that these things because wall space is limited for many homes and a multi-tesla powerwall system is going to take up more wall space than the Franklin a power or in-phase IQ battery system under the new electrical codes at least here in California we won't be able to stack them in front of each other anymore I'm going to be doing a video on the changes in the electrical code in the coming weeks so be sure to subscribe to our Channel by using that link down in the description below I'm not a huge fan of many of these changes and I really believe they're going to affect the adoption of Home storage moving forward in our state at least maybe if we bring some attention to this and apply some actual common sense with what little brains big brother thinks we have maybe we can get some of these codes adjusted just maybe but anyways moving on to the storage capacity of the system items and their backup capabilities each Franklin a power offers 13.6 kilowatt hours of storage at 5 kilowatts of continuous power output and a surge of 10 kilowatts we can connect up to 15 units together for a massive 204 kilowatt hours of storage at 75 kilowatts of continuous power output and 10 second surge of 150 kilowatts comparing this to an in-phase iq10 battery system which offers 10.1 kilowatt hours of usable energy at 3.84 kilowatts of continuous power output and a surge of 5.7 kilowatts we can connect up to four units together for 40.32 kilowatt hours of usable energy at 15.36 kilowatts of continuous power output and a 10 second surge of 23 kilowatts this isn't quite as exciting as the Franklin 8 power but in phase does have a few tricks up its sleeve leave when their batteries are paired with the eighth generation my converters you can actually combine the solar power output with the batteries capability and you can give yourself an extra boost in continuous power output during the day depends on you know the weather but you could be looking at anywhere from one kilowatt to 16 kilowatts depending on your end phase micro inverter and the size of your solar system now moving on to the Tesla powerwall which offers 13.5 kilowatt hours of usable energy and five kilowatts of continuous power output and a surge of seven kilowatts we can connect up to 10 units together for 135 kilowatt hours of usable energy and 50 kilowatts of continuous power output and a 10 second surge of 70 kilowatts it's pretty obvious that the Tesla powerwall for being relatively unchanged for the better part of five years is still a very competitive battery but Franklin has done a good job at literally taking something like the powerwall and made it even better with their a power in Phase they sadly fall short in some areas here and it's really due to their affixation on using micro inverters and small modular battery design but you got to remember end phase my converters the eighth generation paired with their batteries well you do get some extra features that you're not going to get with the powerwall and the Franklin this leads us to the automatic transfer switch though for all three of these manufacturers as this is what actually dictates how much solar or even generator power you can connect to the battery system because we all love a trifecta of power solar battery and generator keep in mind there are some design variables but for the most part all three companies allow for up to 80 amps of solar which comes in to be roughly 15.36 kilowatts AC this could be around 20 kilowatts of DC where Franklin tends to stand out with their a gate as their add-on kits a 200 amp standby generator connection test for their generator connection is 100 amps and when you look at end phase allows for up to 80 amps of generator input there's two more things left to compare and these things are probably the biggest factors on whether or not you get a battery backup system for your home and that's the warranties and price now sure there are plenty of other things to compare and consider like software user interface service network you know how how good is their service network EV integration and so on but these are all honestly things I feel we could on we could discuss after you get your hassle-free quote from us starting with the Franklin whole home a-power which features a standard 12-year warranty with a minimum 70 battery retention they also have an aggregated throughput warranty of 43 megawatt hours which comes out to be roughly 3161 Cycles if you cycle the battery every day from 100 to zero Tesla offers a standard 10-year warranty with the same minimum 70 battery retention and an aggregated throughput of 37.8 megawatt hours which comes out to be roughly 2 800 Cycles again if you cycled the battery from 100 to zero and last but not least end phase IQ batteries feature a standard 10-year warranty with a minimum of 70 percent battery retention I think we're seeing a pattern here but they have an extended five year warranty for a total of 15 years with a minimum of 60 percent battery retention this extended warranty costs you roughly a thousand dollars per iq10 battery you have to buy it directly from end phase the standard 10-year warranty from end phase that they offer features a 4 000 cycle warranty or 2.8 megawatt hours aggregated throughput per kilowatt hour whichever comes first while the extended warranty offers 6 000 Cycles at 3.9 megawatt hours aggregated through per per kilowatt hour Franklin offers a better warranty sure you can try to make up reasons to why Teslas is better or end phase is better but end phase and Tesla do not offer the best warranty on paper yeah on paper if n phase didn't include a throughput clause and their warranty and just did a time frame and a cycle they'd beat both Tesla and Franklin but they have a throughput clause so when you take that into account it makes it a little bit harder for them to just automatically have the better warranty but enough on warranty talk let's talk price because that's what you've been waiting for how much does one of these systems cost if you're getting it with a brand new solar system and if you're retrofitting it to your existing solar system pricing provided is a cash price so there's no Finance included pricing shown is an estimate and is subject to change without notice I'm including pricing because it helps give a gauge you might get a quote cheaper you might get a quote higher everyone's situation is different everyone's house is different and this is a YouTube channel you could be watching this living in Germany or you could be on the other you could be in Texas I don't know where you're living watching this video so I'm just putting costs based upon our area now starting off with pricing for solar and battery backup systems I'm going to be using 25 Rec Alpha pure 400 watt modules this comes out to be roughly a 10 kilowatt DC system I'm going to try and keep the batteries close to the same storage capacity and it's going to come out to be around 13.5 kilowatt hours starting with end phase coming in at 54 158 before the 30 Federal investment tax credit and 37 900 eleven dollars after moving on to the Franklin wh coming in at fifty three thousand five hundred and forty three dollars before the 30 Federal investment tax credit and thirty seven thousand four hundred and eighty dollars after and finally comparing it with a Tesla powerwall coming in at fifty one thousand six hundred and twenty nine dollars before the thirty percent Federal investment tax credit and thirty six thousand one hundred and forty dollars after remember these are TurnKey solar systems with battery backup included that's permitting plan design all everything's included moving on to pricing as a retrofit so no solar just the batteries this includes plan design permitting installation inspections the whole shebang starting with endphase offering 13.44 kilowatt hours of battery backup for 21 110 before the thirty percent Federal investment tax credit and fourteen thousand seven hundred and seventy seven dollars after the Franklin w H offering 13.6 kilowatt hours of battery backup for twenty one thousand forty three dollars before the 30 Federal investment tax credit and fourteen thousand seven hundred and thirty dollars after and finally the Tesla powerwall offering thirteen and a half kilowatt hours of battery backup for 19 153 before the 30 Federal investment tax rate and thirteen thousand four hundred and seven after well there you have it Tesla is still the cheapest battery it doesn't matter if you can think we buffed it or not but it's still in this video the cheapest battery even though they've increased their prices over this year I think they've increased the Powerball price like three times this year now in my opinion I think end phase is still the best solution if you're getting a new solar system because of the iq8 mic converters all the components talk to each other it's an end phases ecosystem it's really robust and basically the micro inverters are talking to the batteries which are talking to the transfer switch all these components talk to each other and and they can all work together to power your home ongoing during a power outage envase has a rock solid system in my opinion if it's a brand new system using those 8th generation microbers but if you're someone that already has a solar system even an older end phase system like m190s m250s ms-280s you might be better off with maybe the Franklin wh because you are getting more storage more backup power and a better warranty and you won't have to wait six months to a year for the battery like a Tesla powerwall well that's it for this week's video thanks for
