Programmable input charge current limiting should be a feature on *ALL* power systems! Especially home energy storage systems! Our local utility gave us a tesla battery for free to be used in a UPS mode, (we have bad grid reliability in the hottest months) in a grid down situation id *really* love to be able to charge it with a 2kw generator but theres no facilities for this. Just having the flexibility of inputs for doing this is one thing but its *vital* to be able to limit the charging current. The tesla wall would obviously stall my little 2kw generator instantly. The fact that this power station lets you do that is VERY GOOD. Please continue to highlight this detail in future reviews

Honestly, I just use the same old inverters I used to keep in my car on whatever batteries I can get ~12v out of. The only worry is the wave type, and even then, that isnt too much of an issue depending on what is going to be powered. Thanks to the death of the analog generation most of my digital equipment eats the 60hz stepped square wave well enough for the odd luxury device on the odd old ass square wave inverter.... The only thing these things offer is the LiFEPO4 chemistry (which I can just get bare batteries if I really wanted to replace the stack of old flooded and sealed lead acid cells I have laying around), the battery charging and power management (not gonna lie, its pretty damn spiffy to not have to break out the 12v charger or jumper cables to recharge, or have a simple managed solar option), and the monitoring (which, I mean, I know my inverters, I know my batteries, the math is second nature by now.....so, kind if a luxury, but still cool. The option for graphing data is very tempting...). For the price of these things, its just too damn high for me and those who have amassed this kind of equipment over the years. That being said, the technology is still really cool and the more devices using LiFEPO4 the cheaper cells will get. And its nice seeing the different iterations working through what does work, what doesnt, what looks nice at the meeting table, and what real world use dictates is more important. However, there is still a thorn in my craw that most of those boards have a debug port, but they wont give us a damn hard data port! Screw app reliance!!! There is enough crap polluting the various RF spectrums, we dont need to rely on the radio all the damn time! Especially if its not moving. Let us just wire a RPi onto it directly dammit! Oh, and really, for completeness, however slowly, it should totally charge off USB C.🤣

I assume making it compatible to both 120v and 240v introduces a lot of complexity and/or inefficiency? I have a 230W laptop power supply that says "INPUT: 100-240V ~ 50-60Hz 3.5A", so the technology exists. But that's only 1/10 the power of this, and it isn't straining for efficiency or compactness. It's literally as big as a brick, and it gets quite hot. Thinking about it, I think it would be really interesting to see someone explain how that works!

For efficiency and safety ratings, there can be a considerable difference in parts. I’m not sure what efficiency they’re claiming on that AC-DC converter, but you would have circuit that works better on one voltage than another if it worked for both. Inductors, capacitors, transformers etc. need to be tuned for their highest efficiency and size. Those wall switchers for your laptop may be 70-80% efficient. In the case of solar charging that’s a pretty considerable loss of energy for a universal circuit.
@BobHannent Жыл бұрын
I believe there is a small inefficiency in making a switch mode do full range. But it's likely to be the additional components needed for making the UPS inverter dual voltage that's driving it. I can't recall seeing a good inverter that's dual voltage.
@stanimir4197 Жыл бұрын
@@BobHannent not just small difference - all parts have to be higher voltage rated and higher current at the same time. That includes the capacitors on the primary, the transistors and the main transformer. For low power it's quite acceptable, though.

Not every use case fits a gas generator. There's use cases where you specifically want a buffer because you already have electric energy coming in intermittently, but don't want the hassle of topping up gas regularly. There's indoor applications where you can't have a combustion engine running and no option to place it outside. There's situations where you don't want any noise coming from your power source. There's some general advantages as well. Gas generators are generally higher maintenance for example. Of course when talking about price to inverter output and energy density, there's not even a discussion to be had - but those two metrics are sometimes simply not the highest priority.
