1. Heavy duty metal shelf ($100)
2. 10kW 48V Solar Hybrid Inverter Split-Phase 200A MPPT Solar Charge ($1669)
3. 8 x Renogy 48V 50Ah LiFePO4 Smart ($640 each during Black Friday x 8 = $5120)
4. Battery cables ($100)
Result:
19200 Wh vs 12000 Wh (60% gain)
LiFePO4 pouch cells vs prismatic cells (lighter)
This is a LiFePo battery backup system that have warranty and customer service.
The closest DIY kit is an EG4 60000XP with the PowerPro 14. kWh battery which is $5500 vs this $7000 for 12 kWh.
2 and 3. No, doesn't work like that.
Don't know about (3).
What happens if one of the individual batteries goes bad? Does the whole bank fail?
Unit this size would use those. The 1kwh battery I built only uses 4 prismatic cells, not zillions of cylinder batts.
Or you can buy a dual fuel generator for $1000 and go .. much longer
The problem, even with Teslas, are that the batteries do degrade. Something like 5-10% the first year.

LiFePo batteries have a better degradation compared to Lithium-ion NMC, far less than your claim of 5-10% first year. These are not the same batteries in your laptop or cellphones.

Wake up. The matrix has you.
For instance, Lucid already activated bidirectional charging where you can plug another EV into lucid and it charges them. Thats 80-90kw battery and a fun car to drive so a win win.
This is a non-vital purchase for most.
But right now, as someone else said, there's just not many options out there except huge pickup trucks even though there's no reason it can't be done with all EVs.

This battery backup is only 7,200W output… and you still need to buy the transfer switch. If that's all you need, you can get a 7,500W Generac with no sales of any kind for 2,000$ with a transfer switch included.
This battery backup is tiny, it's basically a portable generator… not really equivalent to what I'd consider a whole house generator, that's more in the 24-26kW range.
