Welcome

I have a 10mw solar roof and a 800w gas generator. I looked into whole house power batteries or natural-gas standby generators and the were just too expense. I decided to go with a LiFePo4 generator for a few reason:

- Lower cost ~$2,000

- At least 2,000Wh of storage, expandable (see my uncommon expansion options below)

- LiFePo4, slightly heavier batter but 4,000-8,000 recharge cycles if you are good to it

- Portable, I can go camping with it

- Lots of power outputs

- Wide range of charging inputs, especially the solar 10v - 110v input is unlike other manufacturers

First find an Inverter.

Bluetti AC200Max 2048Wh LiFePO4 Battery Backup, Expandable to 8192Wh w/ 4 2200W AC Outlets (4800W Peak), 30A RV Output, Solar Generator for Outdoor Camping, Home Use, Emergency

PowerQueen 190ah LiFePo4 Battery

I purchased this batter to double the capacity of my backup system. Its not as seamless as getting a Bluetti B300 pack but this approach costs at least half the price but you will need a additional toys get it working well.

You can connect this directly to the solar charge port of the Bluetti but there is a limitation - The Bluetti will only draw 10Amps of power, s

This is a 12v-to-36v converter. If you get two of these and wire them in parallel from the PowerQueen to Bluetti solar port you will get over 500w of charging power.

This is a great power monitor for your backup batteries. It iws very configurable for different battery sizes and has an app that uses bluetooth connectivity.

My only criticism is that it can't detect its own current draw, if you want it to be 100% accurate you should power the device with a separate DC power source.
