I have a small house and use anywhere from 20-75 amps of power. Is growatt a good inverter for whole home? They have some of the best prices out there especially on ebay but is it worth saving a few bucks or will it cost me more in the long run?
Best inverter for home

If your minimum usage is 20A (of current, not power), then you will struggle to power it with solar
"Best" depends on what you are trying to do, but the Sol-Ark 15k strikes me as one of the best units you can buy just based on reviews, comments and videos from installers. There may be other top-tier brands that can compete, but Sol-Ark has a very good reputation for their products and support.

You'll need to clarify the 20-75amps comment. To show you why - here's wattage requirements for 120v vs 240v at the amps you list.
20a * 120v = 2,400w
20a * 240v = 4,800w
75a * 120v = 9,000w
75a * 240v = 18,000w
You can see there's quite a range. Perhaps you're saying you have a 100a main panel at your home? and you can sometimes run up to 75a? and this includes 240v appliances such as cooktop or AC?

Best meaning longevity and quality of unit, cheap China crap or good quality. Using it for the whole house using not more then 75 amps of power and around 20-30 when nothing much is running. I have owned cheap and expensive inverters got good and bad from both so its good to know what other people that have been doing this longer than me are using so I can hopefully not have to change inverters every 5-7 years.
30A is like 7Kw... something big must be running

If and when you pursue this, stay away from ebay or Ali and go with a more reputable vendor if at all possible.
Anybody have an opinion on Growatt inverters?
I bought a signeer 48v 6000 watt last year off ebay it is still doing good so far I have learned buying solar stuff on eBay since.
Yeah I have small draw from the fridge, propane heater and whatever small electronics that are on at night. During the day when using TV, washer and other things I don't draw more then 100 amps. I try to keep it around 75 amps or lower depending on what I need to use. I am using a 48v. 6000 watt 240v. Split phase Inverter hooked to my house power for almost 2 years and have never had a problem. I just know what I can and can't use at certain times of the day. In other words I try not to push it to hard.30A is like 7Kw... something big must be running
Yes exactly!

You realize that's only 30a on each leg, right? 100a is a LOT more juice.
Or do you mean 100a from the battery bank? That's a whole different thing.
Oh and sorry it's a 48v. System and yes can run up to 75 amps but not constantly. Thank you! You speak amateur electrician I love it!
200ah. 4-12v lifepo4 with a back up of 4-18650 12v 100ah batteries. Running into a panel with 2-125v breakers to isolate the banks
Yes. I am confusing you guys with my lack of knowledge but we are getting it done!!!!
