Powerwall alternatives with charge EV on Solar and Meter Collar?
I am looking at a grid-tie system with battery. I've really enjoyed the value I am seeing in different batteries and Inverters. That said, a Powerwall has two capabilites I am not really seeing easily replicated elsewhere:
- Charge on Solar: Where I can set a seperate charge limit on my Tesla in the App where It will charge the car above the normal charge limit when excess power is generated.
- The meter collar automatic transfer switch which seems a lot smarter approach than putting in a traditional transfer switch. I have a combind meter and load center so putting something like a 18k between the meter and load center is not an easy option.
I guess my questions are two fold:
1. With alternatives exist in these spaces?
2. What is your opinion on the relative value of these two features (I figure $4-5k).
