In this example we also used one 12V 100Ah battery (1280WH) & Lights at 60W.
(For a more accurate runtime use the Wattage stated on your appliances’ label.)

Determining Inverter Size & Use
Inverter - Size, Appliance Variables, & Surge
Our inverters are rated to handle specific surge or starting watts for large or heavy duty
appliances. To select the appropriate inverter for your system you also need to take
into consideration its
Rated Continuous Power
and
Peak / Surge Power
. For the
best operation of your appliances you will need to understand
Appliance Variables
such as duty cycles or variable active running times, and
Starting Surges
.
Furthermore, you must also take into consideration the Inverters’
Idle Power
Consumption
and include this in your total power draw from your Battery Bank.
