Goals
Input
Seamlessly charge the LiFePO4 battery from both solar panels with MPPT and dockside charger.
The battery came with a 120V charger so the transistion stage could look something like...
- Detect dockside power
- Disable MPPT charger
- Relay to connect charger and battery
If both power sources could be utilized simultaneously even better.
Outputs
36V @ 50A for the motor.
12V @ ~10A for the cabin lighting & "car charger standard" (10A is a guess for now)
5V @ ~5A also for cabin, this might be multiple, smaller 12V -> 5V
Variable @ ? Might be nice to have one variable output. Could be used to run power tools directly, or charge a laptop at 19V directly.
Logging
Data is fun. Log all the data.
I have seen a couple of people using this http://www.sailoog.com/openplotter. If it fits your application, I would like to see how it works out.
