That was where I was. My Honda died & I got a freebie AWD Husqvarna.
Used a lawn service for a while [lazy] and sold the Husky.
Bought the Ryobi when we moved & love it. No indication of any battery deterioration on them yet, but it's only our 2nd summer here. And we'll have much less to mow when the pool is done.

Yeah strangely for me it wasn't a gradual degradation. They runtime just fell off a cliff one day. I think it's a faulty BMS, but it's strange that it's all three of my batteries (and at the same time).

When I got my Ryobi stuff. The cost of batteries was why I bought the mower/blower separately. Got 4 batteries [2 6ah & 2 4ah] & 2 chargers that way, instead of 2x 6ah & 1 with the combo pack.
Yard as it currently sits, takes all 4 batteries when it gets tall.
The cost of 2 extra batteries & a charger was more than buying the 2 separately, so a no-brainer, and the mower I got was a step up from the combo pkg mower.

Is the BMS built into the mower or the battery itself? Could be built into the mower...

How old is it? Might be worth a call to Ego and see if they can help you out before you spend a ton of money on new stuff.

$9200 before install is a lot for one PW, but for my usage that would be perfect. I need to speak with someone about claiming the tax credit again. If so, it brings the cost much closer to a permanent gas powered generator, but without the yearly maintenance costs.
Also, it is cheaper than other battery systems. The Enphase battery is $12k for 10kww. Tesla is 13. I got on the reservation list - I'm curious to see what they can do for me.

Is the tax credit federal or state? If it's a federal incentive then I may look into it as well. Won't be any more than a backup generator for me since we don't have time of day electricity but it would be nice to have.
Federal. VA offers nothing for renewables unless you're a business.
That's the same boat I'm in. It may offset my usage at night, but I'd mainly use it to cover me in the event the grid goes down.

If you have a variable rate energy cost you can charge the powerwall at night when energy is cheapest and then discharge it when energy cost is highest
Also the newest powerwalls should be able to handle your HVAC (
). The older Powerwall 2 had a lower limit on peak output current which meant that 1 powerwall couldn't handle the power surge of your AC starting up, the current model should be able to handle the power surege of most HVAC systems. So you only need to buy one to power your HVAC, my friend had to buy two of the older models if wanted AC during a power outage

Most induction stoves require 240v while most gas require 120v so going from gas to induction usually requires an electrical upgrade so the NYC Public Housing Authority is challenging a manufacturer to make induction work on 120v, and one does then NYC will but 10k units, and other cities will probably purchase them as well. NYC did the same thing in the 90s with energy efficient fridges
Thanks big government for helping to bring down the costs for everyone
In 2021, it launched the Clean Heat For All Challenge, a contest to design a new heat pump that could be installed in a window, like an air conditioner. Most heat pumps on the market have both indoor and outdoor components, and require costly construction work involving plumbers, carpenters, and electricians to set up. A window-unit version would not only be cheaper and easier to install, but would enable renters to take advantage of the technology.
The winners — a model from the longtime window AC manufacturer Midea America and another from a startup called Gradient — were announced last summer. Next steps include extensive testing of the designs, followed by a pilot installation of 60 units before the companies begin fulfilling a much larger order. NYCHA had originally promised a 10,000-unit contract, but the city and state said they planned to triple it to 30,000.
“Purchasing power of NYCHA is a big draw to manufacturers,“ a spokesperson for the state's clean energy office told me. “By including the potential for a large purchase order if successful in the Clean Heat for All Program, we saw a lot of interest from manufacturers because they saw the customer opportunity on the other side of the 'demonstration phase' of this program.“

I've been looking into ways to help with our elec. costs. The past couple months we've had the highest power bills we've ever had in almost 13 years of home ownership. 20% of our bill is TDU charges.
We've got an efficient AC & new windows, and back doors. Need to add some UV film to the window on the front door & maybe have our insulation checked.
Thinking about DIY-ing a radiant barrier in the attic to cut the heat level down up there.

- Faster Powerwall Installation: Use of Tesla Backup Switch cuts Powerwall installation time from up to ten hours down to about one hour – this results in customer savings on the installation budget
- Avoids Extensive Rewiring: For homes where the utility meter is plugged into the main panel box, whole home backup requires the relocation of every load circuit out of the original main panel and into a new backup load panel – this unnecessary work and an additional panel on the wall are avoided by using Backup Switch

I hope so. Right now the Tesla site says install is $6,100. Install on my entire solar array wasn't that much.

From what I've seen, it's essentially a foil backed perforated (for humidity control) that you just staple perpendicular to the roof rafters.
Also seen soffit buffers that get put in first & keep blown in insulation from blocking the soffit vents.

Yeah I have insulation stops already.
I may do the radiant barrier when it cools down a little bit (which is ironic tbh)
I'm looking at this stuff: https://atticfoil.com/

) you want the perforated to allow for moisture to not get trapped & lead to mold/mildew.
