Depends on the size of your battery and panel, and what you run on your inverter. When your battery is charging it takes a % of wattage to begin with from your panel to charge, whats left from your panel output can be used to power things depending on whats left. You may need more wattage to run an inverter if it is charging your battery the same time. It can be done because I do it everyday. I have 5 12v batteries, and 110 w panels, and while charging I can get up to 8 hrs up to 40w continuous power to operate small devices. The more panels, the more you can operate. You will need to consider that you will also have cloudy days on the side, and your panels will not put out as well. You should have a volt meter to keep track of the voltage in your battery, because if it gets too low it could be damaged the battery in time.

Could a portable AC be powered by a solar panel, a trickle charger and a large car battery?
If I used a small solar panel, a power converter, and a trickle charger, would it be possible to run a small portable ac unit on large car battery. Keeping the battery and the solar panel outside and running the cord and power converter inside, would it be possible to have enough power to run the portable unit for 4-6 hours a day or would it be too much for the large car battery to sustain for a lengthy period of time? I would have a second battery on hand 1 to run and 1 charging. Would this work?Could a portable AC be powered by a solar panel, a trickle charger and a large car battery?
