Hi all,
We are building a new, rather large, house and wanted to find out how practical a solution using solar panels and batteries would be or if we should just get a big generator and call it a day? The house will be about 12,000 sq ft and we have estimated we need a 100 kWh generator to power the home and all appliances in the case of an outage. I believe we'd have enough solar panels to be able to make it work out, but using something like the Tesla Power Wall 2 batteries seem to leave us woefully underpowered for any substantial outage (and only 50 kWh output for 10 of them). The Blue Ion 2.0's can be stacked and each have 16 kWh's so you could theoretically do about 10-12 of those with a 9 kWh output per (max) and be able to get 100+ kWH of throughput. We have 2 Tesla EV's so that is part of why the power output is so high. We estimate using 16,000 kWH per month during peak summer months.
So basically my question is can something like this be done practically? I'd like to have solar to help offset power costs during regular usage, but also have a backup system to power the entire house for multiple days if necessary (off grid). Would you rig the solar panels to power the batteries and then have a generator with an auto transfer switch to power the batteries? Is that the best practical solution?
thanks for the insight.
