    30 Percent Tax Credit ?

    Good story except the SS COLA is based on a measure of inflation that includes energy and food costs, to be specific they use the CPI-W. So does the government published CPI number most commonly used, the most recent being a 0.4% MoM for Sep 2022, called the CPI-U. The index that excludes...

    应该是电池反冲了 BATTERY RECOIL, BATTERY BACKLASH

    Yep, for the money I would expect Tektronik. For a lot more money I'd expect Textronix.

    Aircraft still using lead acid

    We fly with two of these: https://startpac.com/products/model-li2800qc-28-5/ we use this https://startpac.com/products/quick-change-y-connector/ So we can use both in parallel for our starts, saves paying lots of money for a power cart start at remote airports

    Replace car battery with LiFePO4?

    Doesn't need to be particularly high capacity, I did it because the LiFePO4 batteries last longer and properly swapping the 12V battery in my Tesla is not a simple process so after my original battery died I replaced it with a LiFePO4. Newer Teslas come with a lithium ion, probably NMC...

    30 Percent Tax Credit ?

    I would think strong proponents of the right to bear arms would be happy to see armed IRS agents, the more guns the better Thanks, like I thought not a tax increase

    30 Percent Tax Credit ?

    Any specifics on how it raises taxes down to the $20k income level? Or is that just something you heard? I suspect you are getting confused, there are no changes to federal income tax laws that target anyone at the $20k income level but there are almost certainly SOME people who file returns...

    30 Percent Tax Credit ?

    I agree that the causes of the current world-wide inflation are complex and not entirely due to the last administration's massive deficits.

    30 Percent Tax Credit ?

    Then a good thing this bill reduces the deficit by spending less than it raises

    BATTERY SELLERS - THE GOOD, BAD, UGLY -- or Jenny (DOCAN) so far so good ...

    I can only speculate that PayPal freezes their accounts, it appears that is what happened when I paid them. Originally they wanted me to wire them the funds because of an issue with their PayPal account and when I declined they got another PayPal account that I made my final payment to but...

    They seem to have to keep creating new PayPal accounts which require new email addresses, delivered fine for me though.

    Can we get a solar system that doesn't feed back to the grid + sizing advice needed

    The new IRA bill makes this an even better approach than in the past. Previously you had to have solar to get a tax credit for batteries and NOT charge it from the grid but now you can build a battery only system and charge from the grid and get a 30% tax credit

    Why would new lifepo4 batteries state-of-charge drop so fast within a week of sitting?

    Because they are junk batteries with high self-discharge? or you are fooling yourself and not really getting them to 100% SOC I'm going to go with junk batteries, no decent vendor selling good batteries delivers batteries with 0% SOC. Probably were at 0% SOC because of high self-discharge
