    Come on? Should I not believe the Polish producer? :D
    If I find time on Saturday, I'll do a test - analog, old junk can I? :P

    Other than a slightly different quality compared to the Kraft Dele, don't expect miracles on the power side. This Fogo F3001R chiller has AVR+ so it's not a pure sine wave. Those devices that have switching power supplies, so they will work without any problems (TV, computer, monitor, etc.). Brush motors are not bothered by this, but it will be much worse with induction motors. Also UPSs connected to such a network can go crazy, because they usually control the voltage at the input much more precisely. Despite the higher price, do not expect that central heating devices (mainly pump motors!) will work properly.

    From this company, the FOGO F2001is is a single-phase power generator equipped with an inverter generator that offers much more accurate voltage and frequency stabilization. There will be no ideal, but it is a much better quality shelf and "better current." Here is a description of this device:


    Once again, I emphasize that a better, cheaper and safer alternative for several hours of power supply is a UPS with a battery. It is also a more reliable system, the backup time of which depends directly on the battery capacity and the power consumed. The absolute minimum is about 70 Ah, but 120 Ah units should already work very efficiently. A solar panel can be used to recharge and maintain the system in standby. A set consisting of a battery and a suitable converter can be assembled from PLN 500 to PLN 1000 (the costs are mainly determined by the battery capacity). However, with full safety for the powered devices, it will still be from a quarter to only half of the money that needs to be spent on a cheap and not fully suitable generator. Adding to this the operating costs (mainly fuel) and the inevitable inconveniences of owning a generator, the choice seems obvious.


    Thank you for your response. I am also planning to buy the exact same UPS.

    I have one more question regarding this mentioned inverter generator.
    Namely, it would be used occasionally for the Novatech ZERN 800 electrofusion welder. Its maximum power is 1450W. The recommended generator power by the manufacturer is 3kW, the only question is which generator he had in mind. Is theoretically - this generator can cope with the receiver of this power?

    Well, I promised, let's go. Saturday, traditionally a working day for cottage needs.
    I put together the "installation" of the emergency power supply for the circulation pumps of the boiler room, I do not post photos because I did not want to clean :)
    The most important - SinusPro500E, the waveform (damn, whether under load or without) looks like this (I blurred it unnecessary :P )

    I took the measurement with the converter disconnected from the mains, only the battery connected. Oscilloscope probe connected through a 1:100 divider (1M? and 10k? resistors ;)
    So it's not bad, the sine is quite shapely - it's powering the pumps after all, not the operating room in infectious surgery :)

    Power plant included - added "panel" with a voltmeter and a 12V socket (from an ashtray from Mercedes W211, what!) Serving either for charging with a source other than the converter, or as a source, I don't know why, but ... Multimeter for the time of checking actual charging voltage. Normally, the system will be turned off - if something is wrong with the power supply, it is a matter of switching the power supply of the boiler room to the emergency set. Hence the voltmeter to view the state of the battery.
    In the picture in battery charging mode
    Not great quality photos, but I didn't feel like leaving my atelier to show such crap :D And that would be it.

    It will work with an AGM 100Ah car battery, because I have a loose one (of course there are no more 100Ah ones), load - two pumps working in the first gear (2x 30W), cyclically. A little should come.
    How many batteries can be connected to such a UPS in an emergency? Will it not hurt the UPS, assuming perfect equal parameters and new Aku.

    A tricky question, actually :)
    The manufacturer does not write about limitations in the number / capacity of batteries, but writes about the maximum charging current - in the case of Sinus Pro 500E it is 10A, and there was no need to take into account the time needed to recharge after exhaustion.
    https://voltpolska.pl/zasilanie-awarcyjne/sinus-pro-500-e-12230v-350500w-zasilacz-awaryjny.html
    If we connect him with three 100Ah batteries, he will go down a bit on charging. If time doesn't hurt us, why not...
    Another thing - such a battery of batteries after discharging will have a large starting charging current, and hell knows how the charger mode limiter works.
    The fact is, the manufacturer hit the cable as if it were a starter :D , unless you do not pay compensation in the event of overheating and fire.
    Maybe the solution would be to add a separate charger (not impulse!) for such a battery? If it does not have a voltage higher than these 14.4, the inverter will see if it sees the battery voltage or the voltage of a foreign charger.

    In general, it is good to ask yourself what this unit will be needed for. And only then look for the right device for yourself. This will ultimately depend on what device we buy. Is the generator to be used in the construction of the house or is it to be used as an emergency source of energy? We calculate the demand so that we analyze what is to be connected to the generator at the same time and check the power of these devices and add up and choose a generator with more power, it also depends on whether these devices will be 1-phase or 3-phase and what type of receivers, e.g. when starting the engine, the current is consumed about 3 times higher than in normal operation. You can also check yourself generator in Leroy Merlin. They have good prices on Hagen right now.

    Hello.
    In order not to create a new thread, I have a question about choosing a chiller for the winter. I know there are a lot of different brands to choose from. I need a generator of about 3 kW and I chose a rather budget one from 2 companies. The first company is Kruzer Th 3900. I know that it has AVR and gives a nice sine wave under load. There are lots of videos on YouTube. Winding made of copper but made in China. I have good reviews. The other company is Hecht. IG 3600 inverter unit. The company from the Czech Republic has a good service, I have their hedge trimmer myself and everything works as it should. Unfortunately, there are no reviews for this unit anywhere. Apparently, it gives a pure sine wave, you can connect laptops, phones and TV. Maybe someone has experience with this and can suggest something. Of course, the budget is limited to 3000, which will only power home appliances in the event of a power outage.

    Hello and welcome.
    Well, I got the choice of emergency power supply.
    I did some reading here and...
    Generally, I was thinking about powering a gas stove + pump + mechanical ventilation. The whole consumes about 230W
    And here I would probably go in SINUS PRO 500 E 12/230V + battery.

    But .. the spouse says "what about the freezer and the fridge?"
    Plus a recorder with cameras ... and I'm starting to think about an inverter power generator. I counted how to start the boiler room of the fridge, TV, some computer and something else, it comes out to be 1.5kW.
    You recommend Fogo. I was looking at the F 3001 IS, nice and quite quiet. But the downside is that it has a small fuel tank.
    If there was no electricity, e.g. at night for a few hours, you have to add fuel every 3.5 hours :(
    Another type is the Inverter Unit - HECHT IG 3601.
    Seemingly cool, 3.0 kW, 12 liter tank, which gives about 12 hours of continuous operation, but ... opinions about the company are different. Mainly about other devices and very little about the unit. It's supposed to be a Czech company, but they download devices from China.
    Therefore, please, if you can recommend a good 2.5 to 3.0 kW inverter generator?
    I was thinking about the price around +/- PLN 4500
    I will be grateful for suggestions.
    Regards

    However, I would go for a UPS with a large battery that will power the recorder, stove + pumps, the generator would also come in handy in the event of a longer power outage and for this freezer or fridge and possibly recharging the battery.
    However, I can't imagine the unit running all night, from which the stove will occasionally take energy or the fridge will turn on twice

    Thanks for the answer.
    What batteries do you use for UPS?
    What capacity, type.

    For the gas furnace - just in case - UPS with "constant phase".

    If you are thinking about a fridge and a freezer - the instantaneous power should be about 2 kW.
    battery 100 Ah gives approx. 720 Wh of energy.

    battery AGM VRLA Motrio - decent battery. at a decent price.

    Bosch-e, Varty draw on a brand that has long ended.

    I'm also looking for something for emergency power. I have a small Volta converter with a battery and it's enough for now, but I was still thinking about the generator.
    Does anyone know the differences between "GUDE ISG 1200-1" and "GUDE ISG 1200 ECO"? Visually, one is larger than the other and has a larger fuel tank. Are there any other differences that are relevant to the user?

    Hello.
    So I bought a Fogo 4001 ISE.
    I've only had it for two weeks so just a quick test.
    Gas stove, electronics, camera recorder everything works without a problem.
    The unit is quiet, and a big plus compared to the 3000 is a larger fuel tank.
    Cool starting from the built-in battery.
