    Hello, I'm going to buy equipment as in the topic, I mean Fogo fh 3001, but I can not get clear information whether I can advise a 2100W angle piece. Maybe someone has such a generator, will suggest something, or some suggestions-alternative?

    Will do the trick. Only, apart from the grinder, you will not connect anything else.

    Of course, the cornerstone will walk on its own, I care more about the certainty if it will work normally ... One of the fogo representatives recommended the 4001 model as more appropriate, but to be sure if the 3001 model is enough or not, it had no other theory and practice. to several stores with an inquiry and everyone says that he can handle it calmly, and one of the sellers wrote that they tested this model with a 2200W angle and everything was ok.

    I also have little doubts whether this unit is too small for such a strong angle. It is true that commutator motors have a lower starting current than short-circuited inductive asynchrones, but the aggregate has a rated power of only 2.7 [kW]. The grinder will probably always be started without a load, and this is a plus, moreover, the aggregate does not have an electronic AVR, which is also good, because it could burn first, the Honda engine also matters. If it was an 1800 [W] angle, I would have no doubts, but with your mother. Anyway, just look at the aggregate selection tables for the equipment (available in many stores with aggregates) and everything will become clear. In addition, you must be aware that power tools with commutator motors up to 2 [kW] should start from this aggregate without any problems, but a loaded concrete mixer with a 1.5 kW engine will not start anymore. It's good that you chose Fogo, because if it were to be a Chinese, it would have to be at least twice as strong.

    For information, I will write that a gregat purchased (fogo fh 3001), I did short tests out of curiosity and like this:
    -Kątówka 2100W starts and works without a problem
    - Amazingly, the 1350W demolition hammer (HITACHI 16KG.) Chokes the generator a bit all the time, but it works.
    -The 2200W oil compressor did not start due to the cold, it hummed when you tried to start, it choked the generator but did not go out. I suspect that at a higher temperature it will go without a problem. If there was light from the power socket, it did not start right away, only after 5 times.
    -Drills, small squares and other small equipment work approx.
    -In some time I will see a 1.1 kw concrete mixer ...
    That's it for now, the rest will come out in the wash.

    That's great. You are one of the few who asks about something and at the end, when he buys something, it informs him how his equipment is doing. Most of them don't even look at their story anymore and don't care about everyone. Coming back to your aggregate and its operation, I think that an empty concrete mixer should start, but if you load it with sand, cement, gravel and water to create some heavy concrete, you may have problems. And with a 2.2 kW compressor, maybe don't try any more due to its heavy start-up because after a few such attempts you will get rid of the generator.

    Let go of this compressor, this is an inductive load, a much higher inrush current will release the generators sooner or later.

    It's a miracle he didn't release anymore. This proves its good quality. Chinese would go up in smoke already.

    It was only for testing purposes, of course the compressor will not ultimately be powered by the generator ...

    Dude, if you bought a new generator, do not do him stupid tests, just read and follow the operating and operating instructions. And there it probably writes that the aggregate should be delivered. During the first 5 mth (moto hours), it should not be loaded to the maximum. It is supposed to work at idle or 50% load, preferably resistive, e.g. a 1000W heater. After this time, the oil should be changed. You should spend some fuel and time to enjoy the trouble-free and long operation of the aggregate later. In the first post you wrote that you need a grinder aggregate and then you say that you want to connect a concrete mixer. Do not do this!!! You have a 2.8 kW generator, so you can connect power tools with 2.2 kW commutator motors, because 2.2x1.2 = 2.64 kW, so you are within its power limits. But the concrete mixer is already an induction motor and in your case 1.1kWx3 = 3.3 kW, it can start at idle. And with a loaded concrete mixer, it can be 1.1x6 = 6.6. Well, your aggregate may not survive some time.

    The manual does not say that the generator should run in ... As for the engine, Honda recommends the first oil change after 20mth. And I stick to it, because I have a few of these engines from gx 25 to gx 390 and I always do the same, i.e. good oil (motul 10w30), taking care of its level, air filter, good fuel and engine warming up before work and cooling when idle revolutions after hard work and so far for a few years all engines work without failures, and some have something to do ... As for the concrete mixer, I did not write about it out of my ignorance, because I assumed that the 1.1 kW engine would not be a problem, only now You made me realize that it may be different ... On the other hand, a few years ago I worked on a Chinese three-phase aggregate and 1.5 kW concrete mixer, the aggregate had 4.5 kW and avr, worked a lot, surprisingly the concrete mixer was going well and the 2000W angle iron was able to turn it off and somehow survived, so fogo should be able to cope even more, considering that the concrete mixer will work a total of 5 or 10 hours and nothing more. Anyway, thanks for valuable advice on the aggregate itself, it will definitely be useful me and other users ...

    And that's sorry. I have an Eisseman H2801 aggregate but with a Brigs engine and I have such a procedure in the manual, so I quoted it here. I thought that was the case with all new aggregates. In the previous post, you also gave instructions on how to handle small internal combustion engines from aggregates. It can also be useful to someone. I know many of them, even in my immediate family, who read the instructions when they break something.
    Returning to the merits of the case. Writing about this 1.5 kW concrete mixer powered by a 3-phase aggregate, it was 230V? If so, it is a bit strange that it started without a problem, but with a grinder, the matter is obvious. From an ordinary 3-phase generator on one phase, you can get 1/3 of the power, in your case it was 1.5kW and you knocked him 2kW with this grinder and that's why he was dying.

    PS
    As it has been written many times on this forum, when choosing a generator you do not only look at the power of devices supplied from it, but above all at their inrush currents. Because it may be that someone buys a 1kW aggregate for a plot without electricity and then is very surprised that a 200W refrigerator or a 500W pump in the well cannot be started.

    Well, it all became clear. A 1500 [W] three-phase motor, assuming that its cos phi = 0.85, has the nominal current In = 2.55 [A]. And the same 1-phase motor has the current In = 7.67 [A]. Assuming the multiplicity of the current only In x 5 at the start-up under full load, you will easily answer why on that Chinese 3-phase aggregate that concrete mixer did not make a great impression. In your current situation, you have a 1-phase aggregate with a nominal power of 2500 [W] and a momentary Pmax = 2.8 [kW], and a concrete mixer with a power of 1.1 [kW]. For this motor, not knowing its cos phi, but assuming that it is the same as above, In = 5.63 [A] and the inrush current under load is at least 5 times. And I doubt that this aggregate would not suffocate such a concrete mixer. You can try to run it empty. If it does not choke the aggregate, then load it, but after loading, do not turn it off until the concrete mixer is completely empty. The working engine will not do anything bad to the generator because it still has a lot of power. It is all about starting up.
    Such choking of the generator has a very negative effect on both the generator and the engine. After such actions, it happens that the aggregate crashes in the most unexpected situations. This is a twisted connecting rod in the engine and this is a burnt generator.

    Everything is very well explained ... A small correction, I do not know if it is important at all, but my generator has 2700kW of nominal power and 3000 kW of instantaneous power.
    Today I tested the aggregate with a 850w concrete mixer, it started normally on an empty concrete mixer, when it was full to 3/4, it did not have any problems with start-up, but during continuous operation, a very slight choking was heard, a 3 * 1.5 line extension cord, 15 mb was used.

    Correct your post because it comes out that you bought a small power plant, 2700kW = 2.7MW. I was probably not wrong, unless a new line of aggregates appeared, that even on the FOGO website they did not change the specification of this aggregate. Take a look:
    http://www.fogo.pl/agregaty-pradotworcze-1/ag...a/2-agregat-pradotworczy-fh-3001#specyfikacja
    Concrete mixer 850 [W] is not the same as 1100 [W] = 1.1 [kW]. Because here the nominal current is In = 4.35 [A] You did not write what was choking during work. Aggregate or concrete mixer? For the aggregate, the extension does not matter, for the mixer it does. And if the generator was tired under the load of 850 [W], I bode it badly. Your tests with a 2.2 [kW] compressor could help him with that. If you overheat the generator windings and they start to shorten, it's only a matter of time and it will be "Zonk". Hopefully you may be oversensitive as the generator is not idling as well as under load.
    I wish you luck.

    Life is an art of compromise and this unit is a compromise between what I should buy (for about 4k) and what I could buy (China: about 1k), it is needed for about 30-50 hours of work, later it will be used very sporadically so It was a bit pointless to spend too much money, when choosing I was aware that I would not predict everything and that some devices may lack power and will be a bit tired, hence the choice of a Honda engine because I know how much they can withstand in difficult conditions and the fogo brand itself as a guarantor I could buy a Chinese for a few hundred with (theoretically) similar parameters or at least a Fogo with a ROTO engine but I chose it as I chose and that's it.
    I know that the extension cord is important, that's why I wrote about it, about getting tired while working with a concrete mixer, I am actually oversensitive, I checked it again this time with a full load and the aggregate is just a bit harder, but it's rather normal.
    I read the aggregate data from the rating plate on the frame and it says:
    (LTP) kVA 3.0
    (PRP) kVA 2.7
    V 230
    A 11.7
    As you can see, I gave the correct data (except for a typo), and the lower ones you wrote about have the same unit with the ROTO engine.

    Don't you know kVA from kW? Active power from apparent power? On the frame you get apparent power (probably for marketing purposes, because it's higher). We are interested in active power and this is 2.5 kW. Generally, the power of aggregates is given in kW and it is so in its specification. Do you have power in kW or in kVA on the engine of the concrete mixer?

    A short report on the use of the generator, it worked about 40-50 hours, it has been unused for some time. The biggest problems were, surprisingly, with ... electric kettles about 2.2 kW, to be sure I checked on 3 pieces and it was clearly suffocating him with each one. Concrete mixer (Chinese) 1.1kW at the beginning slightly choked at the start, then cool, while the domestic production with the same power ran without problems, even started without much problem with a full dense load (160l). Also drills or a stirrer. Slight choking occurred when working with a 1.7kW alligator, and a little more choking when working with a 1350W demolition hammer. I recommend the aggregate itself, very useful for amateur works, for strictly professional use it is worth considering a larger ...

    The matter seems obvious. Power tools were less powerful and their consumption was max. power was not continuous (only start-ups could be a problem), and the kettles consumed their power continuously and therefore the generator worked at almost full load

Topic summary

The discussion revolves around the Fogo FH 3001 generator's compatibility with a 2100W angle grinder and other power tools. Users report that the generator can handle the 2100W angle grinder without issues, although it struggles with higher loads, such as a 2200W oil compressor and a 1350W demolition hammer. The generator's nominal power is noted to be 2.5 kW, with a maximum power of 2.8 kW. Users emphasize the importance of understanding the difference between active and apparent power, as well as the significance of starting currents for inductive loads. Recommendations include avoiding heavy inductive loads to prevent generator damage and ensuring proper usage according to the manufacturer's guidelines. Overall, the Fogo FH 3001 is deemed suitable for amateur use, but for professional applications, a more powerful generator may be necessary.
