How much current does a 12v inverter use for 65w

When using an inverter, the battery current draw depends on the load (watts), not the inverter rating. 12V systems: divide the load watts by 10 24V systems: divide the load watts by 20 Example: 300W load 12V system: 300 ÷ 10 = 30 Amps 24V system: 300 ÷ 20 = 15. [PDF Version]

How big a 24 volt battery should I use with an 800w photovoltaic panel

An 800w solar system could have a 1000w solar inverter and two 24v batteries of 200Ah capacity. This estimation is based on 5 peak sun hours, but this could vary widely depending on location and battery storage needed. Choosing the right inverter for your panels depends on multiple. [PDF Version]
