How many amp hours do I need to run my house?
Think of this as the minimum battery bank size based on your typical usage. You may want to consider 600-800 amp hours of capacity, based on this example, depending on your budget and other factors. Battery banks are typically wired for either 12 volts, 24 volts or 48 volts depending on the size of the system.
How long will a 80 amp hour battery last?
A typical deep-cycle RV battery will be rated around 80 amp-hours, which in theory would supply one amp for 80 hours. However, in reality, if you discharge a lead-acid battery (what you likely have in your RV) more than 50% of the rated capacity you will greatly shorten the life span of the battery.
How long will 300 amp hour battery last?
The battery can deliver maximum 300 amp for 1 hour at 12 V. So energy , Watt =VxI = 12×300= 3600 watt for 1 hour. So a load of 1000w will run for 3.6 hour.
