Many solar beginners confuse power (Watts) and energy (WattHours), and our moderators and forum members spend a lot of time explaining the difference. This morning I reread the Wind-Sun Battery FAQ and found this quote:
Batteries are not 100% efficient - some energy is lost as heat and chemical reactions when charging and discharging. If you use 1000 watts from a battery, it might take 1050 or 1250 watts or more to fully recharge it.
Someone should correct this.
