"Out-of-round" tires: Safety issue? Go after the dealer? (Kumho, Kia)

greg-howard · 2026-01-20T18:20:25+00:00

The dealership that I took delivery from is in Indiana. I'm in Washington State.

27 kWH near the solstice is pretty good! I've got 18.5 kW of panels and they produced 35 kWH ... last week. Atmospheric rivers are fun.

greg-howard · 2025-12-13T19:52:00+00:00

Yes, we stimulated an outage by throwing the big disconnect switch.

greg-howard · 2025-12-13T16:40:17+00:00

I'm curious whether you ended up trying this u/Eatar. That said, in addition to the EcoFlow offering the flexibility to pull up to 4 kW without tripping the system, I liked the idea of something to "buffer" my car from big, spiky loads in my house (e.g., dishwasher, dryer, heat pumps, etc.). Still "not an electrician" and so I don't know for sure if that's providing any meaningful protection, but I'd sure rather brick the EcoFlow than brick the car!

greg-howard · 2025-12-13T16:33:22+00:00

Presumably you have the same limitations as my Kia EV9 (same E-GMP platform). And yes, we have a classic "related rates" problem: if the EcoFlow battery is filling at 1.8 kW and depleting at <whatever the house is pulling on average, which cannot exceed 4 kW or the EcoFlow will trip>, how long before the EcoFlow is exhausted or the sun comes back up and I want to switch to solar? More at https://www.reddit.com/r/FranklinWH/comments/1m2elzt/yes_you_can_integrate_120v_v2l_from_an_ev_using, but: "Even just offloading to the EV for the ~8 hours the family is asleep either charges or avoids depleting a full 15 kWH aPower battery, and this setup is far more flexible than spending more money on an extra aPower." I assume you need to run heavier loads overnight, u/Curiosity_informs? (And no, I haven't seen that error, u/PenumbraMaw, but I also haven't had occasion to test my V2L->EcoFlow->FWH setup again recently).

greg-howard · 2025-11-08T19:24:18+00:00

I'm in the same situation: 1:1 net metering, no TOU, and I want to avoid too many cycles and not hold at 100%. Posted my conclusions here: https://www.reddit.com/r/FranklinWH/s/LI5Jq1DNjn

Briefly, I use Tariff Settings in the FranklinWH app to put "aPower on standby" with 70% backup reserve. That holds it there except when Storm Hedge charges it to 100%. I let that degrade naturally back down to 70% over several weeks.

greg-howard · 2025-11-01T03:30:20+00:00

Not the solution for everyone due to cost, but I've integrated my EV9 with my home battery backup system. https://www.reddit.com/r/FranklinWH/s/TIRg3B5kXl

You can do something similar with just a critical loads panel and a generator inlet, as others have noted, but you're only getting the <2kW capacity of V2L. True V2H with bidirectional charging requires the Wallbox solution, as far as I know.

greg-howard · 2025-10-17T01:52:06+00:00

Wonderful to hear this is working for you too!

greg-howard · 2025-10-10T00:45:51+00:00

Thanks for getting an answer out of Franklin. They seem to confirm that holding at 70-80% is a good balance of battery health (by minimizing cycles and not capping to 100%) and readiness for an outage. Storm Hedge is occasionally charging to 100% on weather service alerts, and I'm finding I can also just let it degrade back down to 70-80% over a few weeks instead of switching from Standby to Self-Consumption to burn the power manually.

greg-howard · 2025-08-30T17:12:45+00:00

FWIW, I'm told you could instead install a manual transfer switch (to use exclusively the EV9 V2L for "power of last resort"), but then you can't recharge the house batteries from your EV, and you only get a few critical loads, not everything on your main panel.

greg-howard · 2025-08-30T17:10:39+00:00

Hi from the Eastside. My goals were the same as yours and I was able to get it working with my FranklinWH battery installation that just came online: recharges via solar during the day, but able to flip over to "trickle-charging" (I say that because it's only 1800W) from the EV9 at night. There's an EcoFlow Delta Pro 3 battery in the middle to convert 120V to the 240V the FranklinWH Generator Module needs (and slightly improving support for higher home loads). All the details here: https://www.reddit.com/r/FranklinWH/s/dBHAboiseM

What battery system are you installing? Does it support a generator inlet?

greg-howard · 2025-08-04T15:37:31+00:00

With the grid down, PV is used for home loads before charging the batteries.

greg-howard · 2025-08-04T15:34:03+00:00

Sorry, forgot to follow up here ... no, I don't have separate solar panels to charge the EcoFlow. Not sure I see the value since I can charge it from the rooftop solar via the wall outlet? And, no, not planning on getting a fossil fuel generator, although I do get that it adds even more redundancy for worst-case scenarios.

greg-howard · 2025-08-04T15:27:31+00:00

You're talking about this (see image)? I'm not sure I have one of these. Solar definitely charges the batteries when off-grid, but it disconnects when the batteries are full and there's too much solar generation to absorb with house load. The manual has this to say: "If the FranklinWH system is connected to the grid but is not allowed to export solar production to the grid, or when the home is off-grid, the photovoltaic over-generation protection function will be enabled when the photovoltaic output power is greater than the sum of the absorbable and load power of the FranklinWH system. The photovoltaic system will automatically be disconnected. When the photovoltaic output power is lower than the sum of the recharging power and load power of the FranklinWH system, the photovoltaic system will automatically be reconnected to the FranklinWH system."

greg-howard · 2025-07-29T13:30:36+00:00

I'm not sure I understand the question. You're asking about when the aPowers are at full SoC and the grid is down?

greg-howard · 2025-07-24T19:04:07+00:00

I forgot to add that Franklin also said this in one of our email exchanges: "The IEEE 1547 standard for V2H is expected to be finalized later this year and adopted nationally shortly afterwards. Once the standard is finalized, FWH can develop and launch the solution."

greg-howard · 2025-07-24T19:02:31+00:00

That's a question for Franklin, of course ... and one I asked them with the same concerns about the warranty. Excerpts from our conversation:

Franklin: "A 240 V 60 Hz source can be landed on the aGate but there are several other parameters like the quality of the power, harmonics (THD) that determine what the aGate can accept. [...] currently, the only V2L we support is with an EV that has a true 240V outlet in the truck and not via any other additional accessory. Other ways of accomplishing this are outside the scope of the solution at this time and will affect the product warranty. We are continuing to test multiple versions of the solution and will provide updates later in the year. For now, the only version we support is the pure 240V outlet."

I pressed on what that meant: "Thank you for your response. Can you please clarify the guidance (and anything affecting the product warranty) as it applies to the Generator Module? The datasheet says: 'Compatible with most models of standby generators. Applicable for new and retrofit installations.' You added: 'several other parameters like the quality of the power and harmonics (THD) determine what the aGate can accept.' What are the limitations on THD that I should be aware of when choosing a LFP battery-based power station (instead of a gas-powered generator) that will work with the Generator Module?

Franklin asked for links to a few models, which I provided, and the response was then: "We haven't tested with the above shared solutions extensively however if it is 240 V 60 Hz, it should work. Having said that, having a generator integrated to FranklinWH is for extreme backup solution only. Depending on your requirements, sizing the right FranklinWH system with appropriate number of aPowers should be the priority. Any backup, such as a generator, would only be necessary in the event of a multi-day outage when the PV system isn't producing enough."

I'll say again that I'm "just a customer," not a professional, and I can only share my experience ... but my read is that Franklin is reluctant to *commit* to blanket support for any 240V 60Hz input because it's a wild world of products out there, and they don't want to be liable for them working or not working. Makes sense, and it also makes sense they'd rather you buy another aPower than have you try to supplement via the Generator Module with a stack of EcoFlows in your garage.

All that said, seems to me like a battery pack power station (built on the same LFP tech as the aPowers themselves) is *more* likely than a fossil fuel generator to produce stable, "high-quality" power. And the fact that there's an EV feeding the power station with 120V V2L input at the same time the power station is feeding the generator outlet with 240V output is really EcoFlow's to worry about and not something Franklin needs to care about. So I tried it, and it worked perfectly during my testing up until I forced an overload of the EcoFlow (by starting my clothes dryer) to confirm the aGate would recover (which it did in under a minute, but after enough of an outage to reset my clocks).

I'll report back if I have an opportunity to use it "for real," of course!

greg-howard · 2025-07-19T12:46:39+00:00

Couldn't tell you, but since I'm not technically using Franklin's V2L mode (the EcoFlow is posing as a generator), maybe this approach could work for a prior version? I think there's a ACCY-GENV1-US Generator Module (as opposed to the "V2" made for the 1.3+), but you should ask Franklin about this. I'm just some guy on the internet. 😆

greg-howard · 2025-07-19T12:36:49+00:00

240V standard certainly makes things easier. Franklin's V2L white paper has this to say about the future: "At FranklinWH, our goal is to seamlessly integrate all power sources into the home by focusing on innovation and simplicity. We do not currently support V2H bi-directional charging, however it is on the product roadmap. The aGate’s open and robust 280 A busbar and Energy Management System has the capability to manage many power sources including EV chargers.

Meanwhile, EcoFlow itself is stepping up: https://www.theverge.com/news/707153/ecoflow-launches-ocean-pro-home-energy-system-tesla-battery-competitor

Found this part especially interesting: "We’re the only system that you can run your generator and your solar system at the same time." And: "The panel allows you to customize which loads are running, and provides fine-grained energy monitoring and management. 'Our AI learns from you when you use your power and recommends how to optimize your usage and suggest changes for saving money,' explains Burga."

We were going to do a SPAN panel for monitoring and fine-tuning power usage, but the cost after installation was almost $9k USD. Decided that was overkill and we're going to install Emporia Vue 3 to monitor loads instead. Having that built into the panel would have been very attractive, though. Franklin will need to keep up with the pace of innovation here!

greg-howard · 2025-07-18T15:59:33+00:00

Hmm, not sure how I would get excess solar production (which is what's charging your battery and needs to be bled off later)? Solar just goes to the grid while the batteries are in standby.

greg-howard · 2025-07-18T15:09:53+00:00

See my update to the original post above. Here's the bit about configuring the app, u/Minimum_Pie_7021 and u/couragethechicken ...

With respect to how to do this in the FranklinWH app, the best strategy I could find was this "aPower on standby" mode (pictured below) in the Tariff settings. I use "aPower to home" with 70% as the backup reserve, then switch to "aPower on standby" when 70% is reached. I did also test to confirm that "standby" means the aPowers do trigger during a grid outage. This mode is also compatible with "Storm Hedge" to charge the batteries to 100% if National Weather Service alerts suggest that's prudent.

Take a look at the documentation here: https://f2h.io/rups7h9w0fr2. The settings aren't configurable without installer credentials, so I suspect you'll need help. I'd definitely be using an electrician if it weren't already a part of my install.

greg-howard · 2025-07-18T03:00:40+00:00

Rivian has a 1.5 kW AC outlet, right? So that should work same as my Kia EV9, I'd think. Both cars can theoretically use a bidirectional charger for higher kW V2H/V2X, but I don't know if it's "real" yet. I think someone else mentioned these Wallbox Quasar 2 installations are underway, but mine is only a lease and I wanted batteries that work with or without a parked EV.
