I have a converted school bus with 6 100ah flooded lead acid batteries charged by an 40a MPPT controller via 6 100w solar panels (more to come hopefully). I also have an AC to DC converter for "shore power", and of course a DC to AC inverter. I would also like to add a grid tie inverter to feed excess power back to the grid, so I could actually benefit from the solar panels when the bus is just parked at the house. Is there a box that does all of this? If there was a solar charge controller that could also feed power back to the grid, it obviously would have an inverter built in, right? This doesn't seem that far fetched but I cannot seem to find anything like this.
Here are my goals
Here are my goals
- When attached to "shore power"
- Power flows directly to AC appliances, does not need to be converted to DC then back to AC
- AC power and solar simultaneously charge battery bank
- If battery bank is full, excess solar gets pumped back to grid
- When "boondocking"
- DC power is converted to AC for appliances
- Solar is used to charge the battery bank
- Excess power can power a motor that I can make do something cool?
