It’s been a few years back, but I recall one house I got a quote on for insurance had a 100 amp panel and I believe I was told it needed to be a 125 or 150 or higher or the carrier wouldn’t touch it. I skipped that one so the details are fuzzy, but I’m pretty certain those were the numbers involved.

I have all my stuff on a UPS, and power my computer/monitor on another UPS that is fed by the first UPS.

We get a look of afternoon thunderstorms, lighting hits, fallen tree branch glitches, etc, and not even a flicker.

JCC,

You have an whole house UPS? If you do I am envious.

I guess what you have is working for you but in my I.T. and Data Center Management days running a UPS behind another UPS was a no no. I have no idea why, probably something to do with harmonics, floating neutrals or other electrical anomalies I never had the education to understand.

Also need to consider how often it will be used. If you lose power every other week, an automatic one might be worth it.

I have a manual interlock between the main and generator breaker, and so far have only used it to test the generator Completely not worth the expense of an automatic transfer switch.

Just My computer stuff. understand my UPS's are only in circuit upon power interruption.
I could understand maybe an issue with full time UPS. or basically running off a battery full time that is being continuously charged until your main grid power drops out.
For my application, that is not for me efficient bang for buck but it is a superior system and costly.

Most insurance companies won't write you policy if you have a Challenger panel. Alot of homeowners are finding they need to change out their Challenger panels for the approved one. FPV is another that is being phased out. Siemens are still approved. This is in Florida. Before you have any installations done get with a home inspector to see what brands are approved in your area.

That is probably the cheapest "UPS" you can get.

Double conversion UPS' protect from a lot more than outages. They protect you from surges, sags, frequency issues, noise on the line and harmonic distortion. Your UPS covers outage only. Is it adequate? Maybe, depends on how crappy your utility is and what your load is.

I work on commercial and industrial UPS for a living. Do I have one? Nope. My laptop has one built in, it's called a battery. It is sufficient for me to save whatever I am doing in the advent of a power loss. The other issues would primmarily affect the power supply, which is separate from the laptop and a spare power supply is way cheaper than a UPS disregarding the battery replacement requirements of one. The rest of the house? It's fine, I have a whole house surge suppressor. The rest is irrelevant for me.

What amp feed is your electric company serving your home with now?
You may need them to upgrade your power service to get 200 amps fed to your panel

For Macomb MI looks like DTE is you electrical utility.

This would be your starting point for a panel change:

This is a handy form for your project. It doesn't look like you will need a site map, Load Sheet, Riser Diagram, Proof of Ownership if you are just 200A or below.
