Wattage Capacity / Duration

09/08/2009 9:52 AM

Hello,

I am not an electrical engineer and I'm quite naive in regards to electricity. I am powering an event using solar power exclusively. The lead acid battery holds a full charge of 32 KWh. The spec also says the unit has a continuous capacity of 7200 watts. If we are drawing 1400 watts continuously, How much time can we run the event for?

Thanks for the help!

Mike

Just a bit simple really

You are drawing 1400W =1.4KW

(capacity 7200W=7.2KW, but you are not utilising it, but never mind, let it be in bank, sorry not bank, that uis dangerous , let it be in battery bank)

Your storage energy = 32KWH

so you can run for 32 KWH/1.4KW = 22.85 Hrs plus (not usually ) minus some hours.
