New Innovative Infinity 1500 Power Station
Recently, the Growatt Infinity 1500 power station debuted. It has an impressive power capacity for its small physical size—1,500 watt-hours and 2,000 watts. At 36.5 pounds, it’s on the lighter side compared to other similar stations. But its big claim to fame is its innovative adjustable inverter.
The Infinity 1500’s adjustable inverter means you can change the available wattage. Choose between 2,000, 1,800, or 1,500-watt output. You might be wondering why would you want to do this? This feature allows you to save power by using a lower setting if you don’t need the total 2,000-watt output. Further, it reduces the fan noise. In the review video below, listen closely, and you can probably hear the fan. It’s not the quietest, but it’s not too distracting if you don’t mind a little white noise in the background.
Similarly, the Infinity 1500 gives you the ability to change your charge speed setting. Choose from slow, regular, or fast modes. Low obviously will charge it much slower. Of course, if you go with the highest setting, that’s the quickest way to recharge the Infinity 1500.
One good reason a van dweller might use this is if they’re recharging from someone else’s solar system. If the host’s setup doesn’t have much power output, the fast charge is probably too much for it to handle. By using the low setting, the Infinity 1500 will charge at a more consistent rate. As a result, the visiting vanlifer can hopefully avoid popping their host’s breakers.
Further, the lower charge settings reduce the Infinity 1500’s fan noise. Noise level tolerance is personal. But if it’s stored in a cabinet, you might not notice it all.
Infinity 1500 Fast Recharge
The Infinity 1500 has an impressive fast recharge capability. You can charge it all the way to 80% in just one hour and 100% in two hours. It features a maximum AC input of 1,500 watts for wall charging.
You can also fully recharge the Infinity 1500 with solar panels with up to 800 watts. This is on the top end of input capability in the mobile power station market. If you max out the solar input, you can fully recharge the Infinity 1500 in just 2.5 hours, which is pretty fast for solar charging. Fortunately, it has universal connectors. So you can use the Growatt folding solar panels or almost any other panel.
Lastly, you can also recharge the Infinity 1500 in a car. Just plug this into a cigarette lighter port. Unfortunately, it will take 13.5 hours to charge fully, so this method is recommended only for topping off the battery or for extra-long drives.
Infinity 1500 Safety Features
You don’t want to worry about safety when you use a power station. That’s where the Infinity 1500 shines. It comes with an industry-leading battery management system. Notably, the BMS is often considered the brain of the battery pack. It is critical to the battery’s safe operation, overall performance, and longevity. Additionally, the BMS protects the devices plugged into it.
To do all this, the BMS monitors every one of the cells in the whole power station to keep track of what’s going on. If something happens, like one of the cells has a weird overload, it’ll shut the whole thing down.
More specifically, the BMS in the Growatt Infinity 1500 prevents a device from overdrawing while in use and a power source from overcharging the battery. It also monitors the remaining charge in the battery, the amount of energy entering & exiting the battery pack, and cell voltages. The BMS uses this data to know when the battery is drained, again, to shut it down to avoid damage.
Another safety feature of the Infinity 1500 is an Uninterruptible power supply (UPS) – basically, a backup electrical source. So if you have the power station charging from a wall socket and have something like your computer plugged into this when a power outage happens, it will keep running your devices. The idea is to prevent damage or loss of any unsaved work.
However, you have to anticipate this situation for the UPS function to be effective. Nonetheless, it’s a good feature of the Growatt Infinity 1500.
Infinity 1500 Power Station App Control
App control is one of our favorite features of the Growatt Infinity 1500. You can control all the features like turning on and off the DC and AC power. Of note, you can connect to it via Bluetooth or Wi-Fi—internet connectivity is not required.
Of course, the app shares how long the power station will take to recharge fully. Even better, you can monitor how long the Infinity 1500 will run based on current usage. For example, if you have a few things plugged in, you can see the number of hours it will power those devices.
Infinity 1500 Ports
The Growatt Infinity 1500 power station features 12 different outlets. One side includes four AC outlets and a cigarette lighter power port (13.6V, 10A). It has various USB ports on the front—two USB-A, two fast-charge USB-A, and two USB-C. Additionally, it has a wireless phone charging pad.
Infinity 1500 Power Station Lifespan
The lifespan of a power station is directly connected to the number of battery cycles or “lifecycles.” A cycle describes the complete charging and discharging sequence. This involves going from full charge to 0%, back up to 100%, then down to zero.
Commonly, you’ll hear that a portable power station has 800 life cycles up to 80%, like the Infinity 1500 power station. That means that after 800 cycles, it will only charge up to 80%. However, if you only run the battery down to 50% and back to 100%, the 800 cycles translates to 1600 “half-cycles.” After that, the battery still functions at 80% efficiency.
With that said, a LiFePO4 battery features about 3500 lifecycles compared to an NMC or lithium-ion battery. Other factors that affect power station lifespan are usage conditions and maintenance.
Infinity 1500 Downsides
While app control is super helpful, the absence of a touch screen on the actual power station is disappointing. You can see the charge level and if AC or DC power is turned on. But you have to use the app to change any other settings.
The screen on the Infinity 1500 power station goes dark after a few minutes, which is frustrating. Unfortunately, the only way to make it visible again is to turn it off and back on. Practically speaking, if you want to monitor the battery level, you must view it on the app.
There are buttons on the Infinity 1500 to on the AC and DC power; the app isn’t needed for that. Also, a touch screen is less important for some. A van dweller, for instance, might store this under the bed and then would need to rely on the app to control it.
Another tiny weakness is the door cover for the charging ports. It’s just asking to get broken off!
Infinity 1500 Upsides
Overall, the Infinity 1500 is a well-rounded portable power station. In a nutshell, it features large capacity, compact, and truly innovative features—adjustable inverter and charge settings. The relatively low weight makes it truly portable. With that in mind, it is also easy to carry around with its sturdy, easy-to-grip handles. In contrast, some power stations’ hand-holds are too close to the unit, making it difficult to get your hand in position.
Lastly, the Growatt Infinity 1500 power station has a two-year warranty. That is not common among power station manufacturers.
Infinity 1500 Power Station Cost
So how much does the Growatt Infinity 1500 power station cost? It typically retails for about $1,600, which is on par or less expensive than competitors on the market. But right now, you can get it for $1300. Remember to take all the above considerations into mind when deciding if this portable power station meets your needs.
