BU-303: Confusion with Voltages
The voltage behavior under a load and charge is governed by the current flow and the internal battery resistance. A low resistance produces low fluctuation under load or charge; a high resistance causes the voltage to swing excessively. Charging and discharging agitates the battery; full voltage stabilization takes up to 24 hours.
Car battery voltage readings different with no load
For example, assume you have a 12V battery and it read 12V exactly when measuring it. Imagine this battery has a 0.2 Ohm internal resistance. You then add a load of 10 Ohms. Use the voltage divider equation [Rload/(Rbat+Rload)]*Vbat = 11.76V. This is why you get a variation in voltage measurement when you measure it with and without a load.

Best practice: Should I charge a battery while also pulling load?
To charge the battery during a load condition the charger must supply enough current to satisfy both the load and the current demanded by the battery. If your solar setup can''t do that then you must inhibit the load from coming on while the battery is charging. Second, the inverter must be capable of accepting the higher voltage.
