But That is Ridiculous
If grid goes down, so does your solar power! That's not acceptable for critical operations during the day. There is a complex solution: essentially set up another off-grid inverter system that powers your on-grid inverter without grid. Ridiculous and expensive. [3] and [4]
Solution - OSE Hybrid Inverter System. No batteris, up when sun is up, no grid needed.
Disadvantage: up only when sun is out.
Advantage: no batteries needed. Switch back to grid as needed.
Key: have enough PV to run everything that you need, and to shut off loads via a smart controller. Using cheapo 63A automatic transfer switches with Arduino will work. Get out the CNC circuit mill and build circuits as needed.
