When using a genverter for power there are two modes of operation; a) silent mode and b)charging mode. Each mode has its advantages and disadvantages.
Silent mode, is just another name for the time you’re running on battery power and have the power inverter converting the DC to AC for your appliances. The advantage here is that its quiet, but you don’t want to run any of the larger appliances for long. Large appliances will bring the batteries down in charge much more quickly.
“Free Power Time”, as my wife likes to call it, is when we are running the generator to charge the batteries. Yes its louder, but its a great way for everyone to connect with their “inner power pig”. With our 6000W generator, Jackie loves it because we can run things like the dishwasher, or even the dreaded electric iron! This is the time we also run the well if we need to top off our 2500 gallon water tank.
I guess “free power time” isn’t 100% correct, because with gas at nearly $3/gal, I estimate we pay something like $1.50/hour. Not free, ok, but our “inner pigs” are happy!
Please Note: Even when running a small emergency power genverter, this is often the time to fire up that electric coffee pot!

Running strictly on a genverter is still more economical than running a generator full time even when the maximum power is not required. When properly matched the generator puts out slightly more power than needed by the charger is that the motor runs at the most fuel efficient power point on the curve. In non technical words you get the most horse power output per unit of fuel burned. Every engine has such a sweet spot.
The genverter allows silent running for most of the time.
A genverter typically allows for running larger appliances than just an inverter power from batteries and a solar panel.
Have you thought of getting a wind generator to supplement your current power system?
Yes, I had some experience with wind and plan on adding it a second time. It must be high and clear from obstructions as I found in the first generation attempt. It is written up at:
