A pure sine wave inverter is needed if powering both sensitive and non-sensitive devices.The minimum size of Inverter is determined by the combined watts of devices turned on and whether we set them to run on modified sine wave or pure sine wave.I nverter efficiency of 90% – we add 10% to the wattage required for inverter sizing.Check out this post to learn more about the differences between Lithium-ion and lead-acid batteries: Pros and Cons of Using Lithium-ion Batteries We purposefully made this decision for the sake of easier calculations and visualization. While lithium-ion batteries can be safely discharged up to 80% (or even higher) of their capacity, our calculator only uses 100 Ah lead-acid batteries in its calculations. Batteries are 100% charged to start and will only draw down to 50% (lead-acid batteries only).To get to its suggestions, our inverter run-time calculator makes a few assumptions:
While this seems straightforward, there are nuances that you need to be aware of.īattery Ah * Battery Voltage = Battery Watt-hoursīattery Watt-hours/Power Usage in Watts = Run-time in Hours Similarly, you would need to plug in 24 in the same formula if you will be using a 24 Volt battery. If it is a 12 Volt battery system, all you do is multiply the usable Ah of your battery by 12 to find its watt-hours and then divide the watt-hours by the load’s required watts (or your power consumption rate) to calculate the total run-time. All batteries come with a predetermined amp-hours label or Ah written on them. To estimate the total run-time, our calculator uses a simple formula. How Does the Samlex Inverter Run-time Calculator Work? Once you have this information, our run-time calculator provides you with two inverter options that you may purchase to satisfy your power needs.
For instance, you might want to know whether you can run a space heater using a 12 Volt or 24 Volt battery through an inverter? If yes, how long can you keep the heater running using this battery system? What size inverter do you need to power this space heater along with my laptop, mobile phone, and an electric drill? To better answer such questions, Samlex created the following Inverter Run-time Calculator which allows you to visualize how the loads that you put on the battery interact with the inverter.Īdditionally, as you add more devices to power using your desired battery system, the Samlex Inverter Run-time Calculator quickly does the calculations behind the scenes and produces an estimated total run-time based on your selected battery bank and load size. One of the most frequent questions that we get is how big an inverter do I need? It depends is usually how we start the answer – as it depends on what you are trying to power (load requirements) and the battery size (Volts).
