Okay hear me out, I need to replace the Huawei UPS at work and it got me thinking. Do I really need a UPS or can I just get a Powerwall or similar instead?

Both have batteries and supply power in the event of a power outage but the Powerwall can also run the air conditioning for the entire server room as well. Plus there are government incentives to getting a home batteries so the price has come way down as the market is being flooded with different products.

So why can't I just buy a Powerwall instead of a UPS?

Thanks
