An inverter with a nominal value of 800 watts and a peak power of 1000 watts costs 2200r, and a generator costs a lot?

Small generator with a capacity of 1 kW from 5000 rubles. The weight is comparable to a battery. Gasoline consumption is also not great.

where do they sell them? or can you tell me the site?

Yandex - find everything! Here is the first link for the query "gas generators": http://www.gm-gen.ru/gasoline_silent_model.php with the 1kVA model of interest. I didn't even look at the rest of the links, there are plenty of them there. You can also refine your request...

Is that what they teach you at school?That the stabilizer and accumulator are one and the same and the latter converts current from DC to AC?!Or inspired ?

After: "after all, he keeps energy", he didn't put an end to it. I mean, the stabilizer transforms. And the accumulator, in the sense that probably the device consists of 2 parts: from a battery (something stores energy), and a converter (as I understand it, an inverter) that converts current from constant to alternating. And if it would not be in the accumulator device, convert what then?? I'm not very good at physics, so please let me know that the battery doesn't convert current. So thank you!! Otherwise, it would have been used long ago.

I explain it on my fingers. Initially, someone mentioned a device that computers are connected to at home, which is where it all started. This device is called an "uninterruptible power supply" (UPS or UPS in English). In the simplest case, it consists of:
1. input rectifier (AC and DC);
2. charger-charges the internal batteries of the UPS;
3. batteries (if they are not present, then we get a kind of mains filter instead of the UPS);
4. inverter (DC to AC).
There are also much more complex schemes, but this is not important for us. As a result, we charge the UPS batteries at home from the household network, drag the UPS to the forest and turn on the lamp on it. We wait until the power in the batteries runs out and drag the UPS home to recharge. The time of operation of the UPS in offline mode depends on its power, lamp power and battery capacity. As a rule, if the load is 100% (the lamp power is equal to the UPS power), then the batteries last for 7-9 minutes. When the load (lamp) power decreases, the battery life increases, but not linearly.
All this is much more convenient if you use a car battery and a separate inverter, which has been repeatedly written here.

Not some banal one-it depends on where. In the steppe Crimea, for example, banal.

How banal is it? Approximately how many pieces arrive at the light during the night?

Not an accumulator,but a stabilizer.And a slightly different action.I don't think it will last.Most likely, the same 15 minutes will be, if not less .And even then, if only removed from the network. And not every accumulator will last 5 hours without recharging.So, no suggestions on this.Either a generator, an inverter, or battery-powered LEDs.

The UPS from APC has 12v/7Ah batteries. These are exactly what entomologist equipment dealers sell for powering UV lamps. The price is 600-700r, so draw conclusions.
