Solar minus house load. Very concise.
When the result is positive the battery is charging, typically during the day.
When the result is negative the battery is being depleted, typically at night.
Common battery monitors (shunt on negative post) display volts and amps in/out of the battery. Many solar controllers display volts and amps supplied by the solar.
A meter to measure dynamic house loads is not as common but a few posters have installed one. I recorded static house loads with my battery monitor by noting the amps turning on a light and recording the difference. I did this for all house loads.
Charger minus house load is the same but usually the charger exceeds the house load so that the batteries are charging or maintained at full charge.
