800W isn't that much, you can't boil water with that. But I do like how simple and easy it is to set up. Tis a shame caravan season is over for us lot in the UK. Thanks for the video Chris very straight forward review as usual. 👍
Yes 800W is the output max for this plug in grid style so designed for light loads, maybe run you laptop, lights and a few light appliances over night for a few hours.
I read the page, said you can build with multi ones, so your get N*800W. That is great for need a big consumption house.
Yes you can plug in more, sorry I was just talking about one main unit here. So with say 3 of them you can then cover up to 2400W for example.
Would 800W be enough to power a top end gaming PC + 38" monitor?
@@svlagonda7417depends on the specific spec of the PC, the efficiency of the PSU, the workload being done and if there are overclocks on the system or not.
Assuming you are just gaming *or* just rendering I'd say yes.
As you already have a unit,would you mind giving us a round on the MQTT capabilities in another video? I'm anxiuosly looking forward to this feature in order to use it with home assistant.
It's a prerelease unit they sent me and unfortunately some things aren't available on it.
As we updated in the INDIEGOGO, this feature will realease after crowdfunding. Thanks for your trust.
@@MarstekEnergywhat will be controllable via mqtt? Set Input and Output for storage? In steps or free values? When exactly will thus Feature be available?
@@MarstekEnergy if the outlet is in the backyard with its own circuit, will it reach a different circuit inside the house where the small AC is plugged?
Just curious where a could get that micro inverter you have there? Love this kind of content. Bought my Fiido T1 ebike from your review of it! 😅
Hi, it's just a cheap one a GTB-800 I bought to test with this system. 800W so matches the max output perfectly. It gets mighty hot when at 800W but they all do as it's passively cooled no fans. Thanks, I also love ebikes, solar types of system like this and the huge battery banks. Fiido t1? Nice! Such a great practical bike I loved using it for small shopping runs.
I'm already six minutes into the video only to realize this is not a power station but a mini Powerwall/battery energy storage product! No wonder it uses those cables and a grid tie inverter unit meant for the roof.😅 I'm the guy in your power station videos that wish power stations should have a feature to dump energy in the night which is exactly what this Marstek does however this does not have AC outlets.
It should be easy to transform this to a portable power station but I can't find any inverter with MC4 connectors, they mostly want to connect directly to battery terminals.
Oh anotehr guy in the comments here also said the same no AC ports! It's just not that type of set up. As for the feature you speak of I wish and hope to see soon with those powerstation from Bluetti and Ecoflow. An option to plug them into the home grid and dump power like this can. Wonder why we don't have that yet?
@@Techtablets I guess most consumers and product engineers still think of power stations as backup generators where it should always keep its energy until emergency or an outing. This is flawed because power stations can be charged daily from solar and batteries don't need to be drained completely in just one hour in the evening. In other words, the chance of a drained battery and power failure happening at the same time is very low.
Fanless, simple and works with my inverter.
Yes it's 100% fanless and works with your own panels and Microinverter.
Thank you. DoD would be better to set it to 95% not to wear out the battery in the winter month, correct? Can you set it up to always let 100W into the grid and let the rest charge the battery and if that is full passthrough the whole energy to the grid?
Great for small households or low wattage home baseloads. More cycles 6000 is great too. Any link for a reliable microinverter?
My using one that I go from Amazon, unsure if it is reliable yet as it's only bend 9 days it goes really hot but so far so good.
In order for this to work, I have to install an 10-50 plug. This plug will feed electricity to the unit when not in use. Is it the AC Plug that feeds the house or the smart meter. I find the video and your diagram conflicting.
App regisitration required? Is it secure? I would put this on a seperate network one paired to the app never to the home network you use. Also monitor for any malisous packet data going to Chinese servers and block outgoing ports.
You can connect via Bluetooth to your phone only. And not give it wifi access and password credentials. As mentioned in other videos I have no network packet sniffer or whatever to read and monitor data packets I don't have knowledge in such things.
lmao.. dont worry bud, your data is already going to US servers
It is compatible with ecoflow power stream?
I'm looking at Legion Solar and they have an "Off Grid Controller." When power goes down, it will automatically turn on power to supply power to an off grid branch circuit. Is this possible with the B2500?
I don't think that's possible with this style of system no.
Wait a minute! Something appears unclear in some of the responses to questions posed. From my understanding, this device will only power appliances plugged into the same circuit in which the B2500 is plugged. In the residential context, considering the fact that the power supplied to the home passes through circuit breakers or fuse before it leaves the panel and goes into the home through branch circuits, this device will not power the whole house as there exists multiple breaks in the homes circuit. In essence, if I have 20 breakers and my fridge, stove and ceiling fan are all supplied power on branch circuit A, and my B2500 is plugged into branch circuit B that supplies power to my master bedroom A/C, TV, etc, my fridge, stove and ceiling fan on A receive no power from my B2500. Am I correct? If this is accurate, why not make the product more agnostic by enabling the device to be integrated as a “whole house” power device? I would hate to log this thing around depending on my consumption. The alternative would be to buy multiple units, but at that cost point, I’d rather seek an alternative product.
Please correct me if I’m mistaken here because I really like the simplicity of this product.
Thank you.
It will power all on your home circuit up to 800W, and over this the rest is from the grid. But it has to be connected to the grid this isn't a off grid solution.
@@Techtablets Wow! Impressive…Thank you very much for the quick response. So I presume the 800W max is a daily limit - i.e., if it reaches or exceeds that limit in a day, the next day resets the limit, and can it be increased with additional batteries or B2500 units chained together?
👍👍👍👍👍👍👍👍👍👍
Thanks for watching!!
As far as I know, the inverters and micro inverters need to have AC power from the grid in order to allow them to start to work (= to supply electricity to the house).
Therefore, this device can only operate if there's power coming from the grid.
If the grid is down, even if the battery is fully charged, you can not use it (= it will not supply electricity to the house).
Am I right?
Hello, yes you are 100% correct. If you have grid power offline this will also be down without the microinverter being powered.
what if you have a solar generator hooked up to a ats feeding power to that plug @@Techtablets
How can you handle the zero export control?
Their smart meter handles that, but it's an optional extra.
Will you get a review of Huawei mate 60 series?
Yes when the global release comes I think I would get a review unit from Huawei.
I might have missed it, but how can i configure the output wattage? Output turns on when "0-500W from PV panels detected" ok, meaning we have a Sun down detection. , but then i saw only Output 1 and/or output 2" toggle on/off. But is it not possible to set the output limits to e.g max 200Watt?
Yes not with the current app, btu it's coming and you need the smart meter to be able to limit the output from 800W to 0W on the fly as it monitors the demand. With my router I can control this and got it down to 400W so as to not loose whatever I'm not using and make the battery last most of the night to run lights, my laptop and other basic needs. Since the app isn't final and this a pre-release model it's not actually a review but more hands on preview type of test.
Also I set mine to 50W sun down detection, fully charge then discharge and then it pushes the power to my microinverter.
@@Techtablets Thanks for the answer. I fully understood the benefit of the smart meter-box, but i know pretty well my basic power consumption at night. So is it possible to set e.g. 1800-0800 150 watt to set in the app WITHOUT the smartmeter box and WITHOUT adjusting the limits of the micro-inverter? Pure connection app/box
@@PV-InteressenRight now wit hthe current app state no. I hope they add this. For now only their smart inverter is the option so I also want this feature to limit my output wattage and schedule it just with the app instead of wasting so much storage pwoer. It should be possible I would love to hear Marsteks input on this support in future app updates. @MarstekEnergy
@MarstekEnergy Any help with this?
Hey Chris did you pay any taxes ordering from EU? How did they take to ship your perk?
Thanks
No taxes and it too about 4 weeks.
What is the max output and will it work with more than 3 units?
800w per main unit. And yes you could use 3 units.
Yes, work with more than 3 units, depends on the power regulation in your country.
each B2500 will max output 800w. if you use more than one , you get 800W*N, depends on the number of B2500.
2 things :- I have a 4.3 kw ........ 10 x 430 w solar panel system with a string inverter. Can I add this Marstek battery to this system ? ...... Secondly if I wanted to set it up independent of the other system, what capacity ( wattage ) solar panels do I need , and how many.
Hi, that's too much this can only handle 1000W max 1kw which is 2 x 500W per PV input. If you want ot set it up oneseperatly just need 2 x 450W or 500W panels. Here an okay panel like my Risen are only 125 euros each for 450W. In this video I used just one 450W rated panel that at it's peak at midday will output 400W max, I might add another as this battery is for light loads during the night (PC and lighting). Daytime I have a roof full of 450W panels 7.2kw, 16 panels in total but this system doesn't use battery storage, we sell to the power company the excess :)
Thanks for that comprehensive answer. I understand it now.
1. well yes, what you actually meant is adding it to your home electrical system. a Grid tie inverter can be simply plug into any power outlet.
2. The number of solar panels to add depends on your budget or whether you have excess solar power or not. if for example your meter reads zero or exporting to the grid in the afternoon then you may need one solar panel around 500 watts just to charge to fully charge the battery during the day (assuming your location has 5 sun hours worth of solar).
Does in only power the outlets on the circuit the B2500 is plugged in? If your TV, let’s say is in another circuit, it wont be able to utilize B2500. ??
Not it will power all in your house on that same circuit yes. So everything up to 800W the remaining comes from the power company grid. It will reduce your powers consumption and you get the savings even if you're using a microwave which is over 800W it will give you the power up to that 800W. The rest from the grid and 100% from the grid again once the battery is depleted.
IstvanNagy86 Expalins this well:
You just plug this into one of your AC sockets, and it will automatically supply devices in your home connected to your normal wiring, either directly by the solar panel, or by the battery. If the load is higher (or there's no sun an the battery is depleted), that's used from the grid.
@@Techtablets ok so plug to one outlet / circuit and it can power all other outlets (entire house, you said) from other circuits, right?
@@Techtablets ok so plug to one outlet / circuit and it can power all other outlets (entire house, you said) from other circuits, right?
A bit better than the Ecoflow Powerstream system imo.
It is yes and I still use it, the ecoflow microinverter wasn't really that good me for. Marstek have a new model coming that will allow for 1000W input and 1000W out so that's good with a built in inverter I think. I will have it soon to test.
@@Techtablets wow
@@Techtablets awesome would be 1200w input (3x400w) with 1000w output 😎. 200w would be used to charge the battery.
Wait so this just plugs in, where are the power plugs?
You just plug this into one of your AC sockets, and it will automatically supply devices in your home connected to your normal wiring, either directly by the solar panel, or by the battery. If the load is higher (or there's no sun an the battery is depleted), that's used from the grid. Though check if in your country this can be used, unfortunately here in Hungary it's banned right now because you can't feed back energy into the grid using this way.
Thanks for the reply couldn't have said it better myself. Shame it's banned in Hungry hopefully that changes.
So what's to stop you feeding some of that wattage to your neighbours then?
Why
Well if you aren't using all you send to your home grid then yes, it will go to the grid as I showed with the smart meter.
With intelligent allocation, B2500 can output exactly as your using. this function will need to work with MARSTEK Smart Meter together. So that you will not feed more power to Grid.@@Techtablets
@@MarstekEnergy Oh something I didn't have to test, but thank you for the correction! Seems a good investment to also get that in order to save wasting power.
@MarstekEnergy will it be possible to limit the output via the app? For example, could I set it to feed just 400w into the house to cover my baseboard and extend the run time of a full battery?
I think that its not worth it at the price. 800w is not really enough even for an RV. Doubling the system so we could get 1.6kw would double the cost of the setup to a point where I could have my own custom setup
Yet again the price pls?
It's in the link in the description it's always changing so not mentioned in the video for that reason.
This review is severely lacking. When can we expect a teardown of this please in a future update video? We need to confirm the true IP rating is it really IP65? What brand of cells they have used, also check to see it's not repurposing used expired Lion cells not even like some of the cheap battery stations were caught doing. Confirm they are indeed lithium iron phosphate battery (LiFePO 4 battery cells) Also check the correct gauge of cables are used and rated for such loads. Batteres should have shock insulation from drops of some form to prevent cell damage and leakage plus BMS tests to see how it handles overloading, overdischarging and shorts due to poor MC4 or user installation. So the only con is it has no handle? You can do better Chris, I think Steve of Gamer's Nexus should take a look at your review ethics and maybe send your unit to him for proper analysis.
This is a hands on only, sponsored video (flagged as such) and I wouldn't be doing any teardowns of such a product. Thanks for your valuable comments and suggestions as always.
It is highly unlikely they are not using LiFePO4 batteries. The smaller prismatic have really dropped in price
@@niffrig I'm almost 100% they definatly would be using LFP, it would be very bad for them if someone took off the lid and found it wasn't. And yes the price of LFP is more affordabel for brands nows. I don't do teardowns of most products and espcially not battery banks!
Does not Work in any way !!!!! Scam scam scam scam... I have already a second one and it works a shit !!! Safe ur Money
Useless product, no inverter function, plugs or USB ports
It's a different type of product not like the power station types I use with built in DC/AC inverter and many plugs.
