What do you think of a system like this with removable batteries?

Having the removable batteries is a great feature. No need to re-wire the house to charge them during blackouts, just remove the batteries and charge them in the car. One question, Is the AC output wave of the Runhood Rallye 1200 a modified sine wave, a square wave or a pure sine wave?"

Can the main unit charge by USB C or are those ports output only?

Depends on cost of the proprietary batteries. Would be very interested in a system that had a plug with terminal wires that you could hook to a lifepo4 battery. The idea of charging a stack of batteries and then plugging them in as needed would be very powerful.

@@macmcleod1188 the possibility of having something like that is why I backed the Rallye 1200 in the first place. The ability to use the battery bars separately, and replace them (or use generic batteries) as battery tech improves are the standout features for me 😁.

This is a well thought out system. I like the ability to swap batteries while the system is still operating. I want to use this system in my greenhouse and I can put this system on each of my appliances which will help keeping me from having to depend on the grid. I'm in the process of buying a small house that sits on one acre of land. I will be using most of the land for my greenhouse so I can grow food year round. I'm going to dedicate 1,000 square feet to growing mushrooms in the proper environment which requires a building built for growing all kinds of mushrooms.

Hope the project goes well!

So much thought put into it but why not LifePo4 batteries, that's very commonly becoming the standard for these backup power packs...

I hope they do come out with LifePo4, but it will increase price and weight. Since battery is swapable. We would have more options and just buy the battery we want within budget. Every company should have swapable battery. I was thinking, you would have a good paper weight when battery no longer charge and can’t swap battery. Never owned one, but now I will definitely get it.

I love the swappable battery idea especially for places like here in Ireland were the weather is so changeable. Just today we've gone from cloud free beaming sun to torrential rain to heavy winds. All in an hour. Now its sunny again. I can't leave my sogen out in that and expect it not to be dead from a weather change and having the battery's being able to be charged direct from the panels with the sogen safely kept indoors would be a major things. Never mind if the battery is in a pocket on the panel you can use shorter cables lessening power loss. Sadly they don't appear to be selling them here in Europe and the efficiency figures do seem a bit low. Cheers for the review. Subbed.

Thanks for the sub! Good thoughts. I’m not sure what their Europe sales plan is but I wouldn’t be surprised if they plan on selling them there.

Interesting re the hot swappable batteries but I often wonder how long the batteries would be on the market for and availability. Interchangeable batteries are great as you can build up redundancy. Very neat system.

The hardest part of the hot swappable system is making a system that is safe to to insert a battery at 100% SOC with a battery that is already in the system at 0% SOC. The batteries have to be isolated or you have to force users to only hot swap batteries at similar SOC charge levels.

Great idea; but the MCC chemistry is a killer for me. That's a lot of money tied to a Kickstart model. I think I would rather spend my money on a component system. At least I would know the build quality and be able to swap out bad components rather than tying it all up into the Runhood power station.

Greater energy density vs higher cycle count. It depends on the use case but understand the tradeoff.

I have the Orange version and I like it. Orange energy bars fit the gray unit?

Yes, they use the same energy bars.

Love it but they need to work on bringing the price down significantly which if they do you would use the extra cash to buy multiple batteries

Why are they still using barrel connectors in 2023?

Oooof is that an 8mm or 5521 for solar input? NO Bueno

@ericklein5097

EVEN WORSE! 6mm is so obscure. WTF were they thinking. The DC barrel plugs are pretty much all limited to 10A or so. Just a bad all around decision.

I have the 600 and it has one bi-directional usbc. Does the 1200? Also, on the campaign, it comes with the MC4 cable.

No, the USB-C on the 1200 is output only. I was told the MC4 wouldn’t come with the 1200 but that’s great if it does.

*Wait a minute ! What do you mean you can only expect the Rallye 1200 to only run for 15 minutes or so at its maximum inverter constant output of 1200 Watts ? 😩💁 This unit should run all day long at its rated nominal sustained output rating !???? 🤔🤔🤔🤔👀Why wouldn't it ? Most inverters are considered to be broken if they don't meet their minimum sustained output rating ?🤔🤔🤔 In other words, I should be able to run an 1150 Watt draw on the built in 1200 Watt inverter all day ? As long as I feed the Rallye 1200 freshly and properly charged batteries, then it should function AS ADVERTISED !!!💁💁💁 I also own an EcoFlow River 600 MAX edition 600 Watt constant output solar generator. I can run that unit all day long @ 600 Watts AC without a glitch. Yeah, sure, the fans kick on and the unit gets hot, but it doesn't shut down from inverter overheating or failure. I would rather have a noisy fan blowing big air to cool a hot inverter then to have poor performance. With most inverters, you should be able to load them up to at least 80 % of their maximum rating (Which would be at least 1,000 Watts AC with the Rallye) without failure of performance.*

Runhood chose to put in a bigger inverter on this unit. I like the design choice because it can run things like a fridge (2400W surge). Most manufacturers don't install an inverter that can output double the battery capacity. One reason is because of what I think you are getting at. There is a trade off because while it can handle the large loads (other power stations this small can't do that), it is hard to expect the max rate (about 2C) at 100% depth of discharge. Thanks for watching and commenting.

@@solarguy Not necessarily. One of the technical solutions is to add a certain type of germanium capacitor (Which behave like a battery themselves with slow discharge unlike normal capacitors), and this will compensate for the higher drain of a lower inverter to battery supply ratio. These capacitors can be added either to the battery packs or installed inside the inverter unit. Might be worth a try ? There was a hell of a lot of press about these capacitors a few years back, now nothing but crickets since the rise of the commercialized Lithium battery technologies (??)

mmmmm wy not just wire the solar panels to the power station . the norm for panel input is xt60 ore 90. for the price of extra energy bars just buy more panels . the system needs more charge power with panel input . lifepo4 battery,s are the norm now . and if you have to swap the battery,s out in the night you run out of time to charge them. maybe 6 briks wil do . The load is just to big for the system you need a bigger system . the one plus is the better usb fast charge ports . ps there is nothing to buy ore see on the links provided . the old one is not in stock ,the othere is a kickstarter? i am sorry but i dont see anything spacial then the special briks too get people hooked , just buy 2 lifepo 12volt batterys and a solar controller . use that to power youre power station .. and no app ??
