It can be tough to stay cool off-grid or during a power outage. Fortunately, there’s a solution:
Portable AC units deliver cooling relief in hot conditions. But you’ve got to have the right setup if your heat relief is going to last. In this article, we’ll delve into how to properly complement your portable unit with battery power stations, solar panels, and other off-grid solutions so that you can escape the heat.
This guide will help you stay comfortable and safe during an emergency outage or while enjoying the great outdoors.
Why Portable ACs Are Essential During Summer Heatwaves
When those summer temperatures skyrocket and your conventional HVAC system starts to struggle, staying cool becomes increasingly tricky.
While not all areas of the country experience extreme summer temperatures, heat waves can strike quickly and often without warning. These heat waves can cause temperatures to rise well above what your standard AC is designed to handle. When heat waves move in, being prepared with a portable AC unit is a great way to compensate for a struggling HVAC system.
Portable AC units are essential for households, campers, and RV travelers. Traditional units on RVs are even less likely to cope with sudden spikes in temperatures, and tent campers may be caught off guard by the heat as well. A portable, battery-powered option like the EcoFlow WAVE 3 can supplement your cooling needs, whether you’re in a tent or an RV, at a campground, or going primitive.
What Power Requirements Does a Portable AC Have?
Like conventional units, portable AC units draw a significant amount of power. This is especially true as they start up. Starting currents for these units can be upwards of 25 amps or 1,800 watts, with running wattage between 800W and 1,500W of continuous pull from the grid.
Battery-powered portable AC units are designed to operate below the 10 amp mark, but are designed to cool smaller spaces. The power demand for portable units can overload the breaker if other devices are being used simultaneously. Smaller units may only require 10-15 amps of energy, but most breakers for normal rooms max out at 20 amps, leaving very little available power for other devices.
Battery-operated units like the EcoFlow WAVE 3 are engineered to require less amperage and smoother start-up demands. Because these units work off-grid, their inverters are designed to avoid the abovementioned pitfalls.
What Are the Off-Grid Power Options for a Portable AC?
Several options are available for running a portable AC off-grid. However, determining the right choice for your situation will require some planning.
You’ll need to consider how long you intend to run the unit, how you’ll recharge it, and whether you want it to be silent, fuel-based, etc. You can make the best choice once you’ve considered what you need for your specific scenario.
With that in mind, here are the typical options available:
Portable Power Stations (PPS): If you’re running a battery-powered portable AC, then a PPS is like having an extra battery pack. If you’re using an upright, plug-in AC unit with a surge potential with continuous current draw, the EcoFlow DELTA 3 Plus can handle most portable units and be recharged while off-grid from solar panels or even your car.
Solar Generators: These generators combine panels with a power station designed specifically for off-grid and sustainable recharging. The EcoFlow DELTA Pro 3 Solar Generator (PV400W) is a great option for long-term and remote use.
Gas Generators: If there’s an upside to gas generators, it’s the high output of power, which is ideal in emergencies. However, the drawbacks of gas are significant, especially for leisurely off-grid use. They’re loud, require fuel, and have a fair amount of exhaust, making them less sustainable and potentially hazardous should carbon monoxide enter your sleeping quarters.
Vehicle Power Inverters: This should be a last-resort option you’d use in a pinch. Inverters and car batteries can be used as a temporary power source, though they are not sustainable in the long term and can’t handle higher-watt units.
How Long Can You Run a Portable AC Off-Grid?
Three key factors determine how long your portable AC unit can run: the capacity of your power source, the efficiency of the portable unit itself, and how much power you need to cool your space.
Mid-range power stations have approximately 2,000 watt-hours (Wh) and may be able to run a portable unit for 3-5 hours. Some larger PPS systems output around 3,600Wh, potentially stretching the runtime further.
What To Look for in a Portable AC for Use Off-Grid
There are four main things to look for in a portable AC unit for solid off-grid use. These features will help you get the most out of your cooling setup:
Low Power Draw: Get a portable unit that avoids surges.
Battery or Solar compatibility: These will be the quietest, most sustainable, and off-grid-friendly options.
Smart Controls: Timers, eco-friendly modes, and remote access can reduce wasteful runtimes.
Compact Size: Smaller units will generally cool more efficiently and are easier to travel with.
Frequently Asked Questions
Can I Run a Portable AC and Other Devices Simultaneously?
Yes, if the power source you’re using has enough output capacity. Checking the wattage (startup and running) will help determine if your power source can handle simultaneous devices, or if you’ll need to pick and choose which devices to run.
Are There Portable ACs Built for Solar Charging?
Absolutely, battery-powered portable ACs are implicitly designed for PPS or solar generator use. You won’t find one that operates on solar alone, as the unit would need to somehow cool and be exposed to the sun simultaneously.
