Setting #28 can be lowered to 15 when plugging into a standard 15a receptacle like you might have at home. This tells the inverter that it only has 15a of power to work with and it will give power to the load (A/C, Microwave, etc.) and stop charging the batteries. If you choose to change this setting be aware that your batteries may not charge if the load continues to be higher than required for proper charging. This would also be the case even when connected to a 30a power source if setting #28 is left at 15 as the inverter does not know what power source you are connected to.
