Aim high, 100 KWh powerwall
#11
It makes no sense to charge your ebike or e vehicles from your powerwall ..

If the solar feeds direct into the e vehicles you will have saved your powerwall work and it will last longer ...

Or just make sure you charge vehicles when the sun is out , then power is taken out of the powerwall into the vehicles at the same time power is going from panels into the powerwall ... so the powerwall voltage is fairly constant , the cells are neither charging or discharging and will last longer.

Bottom line , try to avoid charging e vehicles at night.

I notice that although 33 people have read this thread , only 3 have voted in the poll ...I suspect , like me , most are not sure what a hybrid inverter is , or why it should be necessary to use many ...etc

Anyone care to explain?

Hybrid Inverters are discussed in fairly good detail in the FAQ, found on the main page in the top section.

Completely agree here. Minimize your conversions as much as possible. Charge when charging doesn't cost anything, which is when the sun is out. When it's not possible, better to use a buck converter to go from the powerwall to the ebike pack. If they are nominally the same voltage, then you'd want to use a buck-boost converter that can top off the ebike even if the powerwall is lower.

Nice idea to charge the bikes with a Buck inverter. Will look into that.

48 KWh for daily use seems quite high. Upon reading the title I though you want to build a SHTF system.
2x power aim is fine although in my case I'd go for a 3x.
Anyway, it's quite an objective you've set there, hope you complete it successfully.
