Anker solix power saver kit, worth a try?

've been slowly building out my home solar setup to save money, and I'm always on the lookout for ways to improve efficiency. I already bought the Anker solix F3000 and used it for a while now - it's legit, and really changed my power set up.

After buying it I then saw they have power saver kits to use and they say it can hook up to solar panels + and save even more each month as mentioned by "Make the Most of Solar and Off-Peak Rates" at 30% for my electricity bill!

I was talking to my buddy, and they mention that they needed the Ecoflow stream, but he eventually found out it can only be installed in Utah. I can now say "Hey this system at Anker doesn't matter the location".

Here's the best part: I saw on their Facebook page that if you buy a battery pack, you can get the Power Saver Kit for FREE ($448 value!).

I'm seriously considering jumping on this, and wanted to share the info with you all. Has anyone else used the Anker Solix Power Saver Kit? Also thoughts on this as well before it's gone?
