Adding the respective wattages of the devices you’ll be using will give you a good idea of what size of inverter will best suit your system. The size of the inverter you’ll need is dependent on what appliances you are going to be running on it. So what size Inverter do you need? Hybrid or Standalone? Some appliances will require a large amount of power for a short time (such as toasters, microwaves, blenders), but then revert to a lower continuous draw. The surge is typically up to double the continuous load, and rated for anywhere from a few seconds to a few minutes. Peak (Surge) power: Peak power means the maximum power your inverter can supply for a short amount of time. For example, if you’re watching TV for an hour the usual power needed would be roughly 300W, supplied continuously. You will match your energy consumption with your inverter’s ability to supply Continuous power and Peak power.Ĭontinuous power: This is what the inverter must supply on a steady basis, and this consumption is usually much lower than peak power. It is important for the input voltage of your inverter to match the output voltage of your battery bank e.g. AC power runs most household appliances, and most inverters come with a AC outlet that you can plug a powerboard into directly (to run your appliances), as well as a wired connection (so that you can wire it into your switchboard).Īll our inverters support 220-240V output connections, which is appropriate for use in New Zealand, but not necessarily other parts of the world (for example, US uses 110Volts). The sole purpose of an inverter is to convert the Direct Current (DC) power that comes from your solar panels and batteries into Alternating Current (AC) power. The inverter is one of the four essential components in an off-grid solar system.
