Is there a formula that will give me a ball park idea of how much power I will lose when I run my DC battery bank through a power inverter? Is this something that varies depending on the inverter? Are some brands better quality than others with regards to this? Is there anything else I need to factor in or is it just as simple as saying for every V/A being drawn through inverter X you lose n%?
What do I need to know to make a smart decision about the inverter to buy? Without starting a religious war about inverters are there certain things to know about particular brands/inverters that might not otherwise be obvious?
