The solar panel charges the battery and the battery is hooked to the inverter and the inverter gives me 3 amps of 120 ac power.
Having both inverter and solar charger connected at the same time is not a problem.
However, that said, both units will probably have a small parasitic load when not being used. The solar charger could consume a small amount. The inverter will consume a small amount. The photocell would consume a small amount.
Your plan should still work. Monitor the battery voltage with a digital voltmeter ($10 at Walmart). By the end of the charging day you want more than 12.7 volts. Otherwise you will need to supplement charge for 14 to 18 hours periodically. Maybe once per week.
