Charging Tips
Solar charging is slowest but free. AC charging is fastest but costs electricity.
Use MPPT charge controllers for best solar efficiency.
Avoid charging in extreme temperatures. Cold slows charging, heat damages batteries.
Partial charges are fine for lithium batteries. You don't need to fully discharge first.
Keep your generator plugged in during outages to ensure it's ready when needed.
