For 24-volt inverters, it is 10 %. The battery capacity for a 12-volt Mass Sine 12/1200, for instance, is 240 Ah, while a 24-volt Mass Sine 24/1500 inverter would require at least 150 Ah. The indicated battery capacity is only for the inverter. The capacity required for other loads should be added to it. How much power does an inverter consume?
A quick rule is to divide watts by 10 for 12V systems or 20 for 24V systems. For more accuracy, divide the load by the actual battery voltage and adjust for inverter efficiency (typically 85%). This ensures you can correctly estimate battery drain and size your system safely.
Interpreting Results: Once you input the required data, the calculator will generate the recommended battery size in ampere-hours (Ah). For instance, if your power consumption is 500 watts, the usage time is 4 hours, and the inverter efficiency is 90%, the calculator might suggest a battery size of approximately 222 Ah.
Off-Grid Cabin: In most cases, a 2400W inverter provides adequate capacity for a well water pump (750W), cabin lighting (150W), a refrigerator (300W), and satellite internet equipment (100W). The total demand is approximately 1,300W, leaving about 1,100W available for additional loads such as power tools, kitchen appliances, or a washing machine.
