UPS Volt vs Kemot for Fireplace with Water Jacket: Which Brand to Choose & Why?

Question

Good day.
I plan to buy a real USP for a fireplace with a water jacket. Please suggest which brand of device to choose. Prices and options are practically the same. Personally, I am leaning towards the Volt due to the possibility of setting a lower battery charging current. Surely you have some experience and it is possible that you have even used a device from both of these companies.
Regards.

Kemot works in my boiler room. Three years without charge. 300 watts on a 45 Ah recycled battery. It supplies two pumps with a total of approx. 100W. Now after the warranty I took it apart for cleaning. Good quality workmanship. It always powers my pumps in storms. I recommend. The waveform on the oscilloscope pure sine wave.

Do not buy this brand or you will be in trouble. You will find information about this on every forum.

I use Techtron (with a constant phase because the boiler requires it).

He has a permanently set charging current of 10A. Doesn't cook the battery?

Mierzejewski46 · Answer

Techtron's-tech.300 is your best choice. And domestic production. Kemot does not charge with constant current, these 10A is max. charging current. Chinese but solidly made.

I also thought about Techtron, but ZA-TECH 350. supply-za-tech-350-12v-230v-sinus-350w.html Just a bit more expensive.

Mierzejewski46 · Answer

I bought mine from a friend in an electronics store for PLN 370. He recommended it to me, and since the guy is good at electronics and doesn't sell junk, I took it. Then I delved a bit into the subject and Lechpol is not a manufacturer but an importer from the Far East. I will not say a bad word about this device. Except maybe one. The AVR is poorly developed and the voltage stabilization is a bit lame. Besides, three years I don't know what power to the furnace is. Now, maybe I would buy Techtron more out of sentiment for Polish producers. But only because.

And my Kemot power supply with a Forse 74Ah car battery in the last storms powered a central heating stove with a controller and a pump with a power consumption of 55W for 10 hours. Enough. The cost of the entire power supply is PLN 800.

I bought a month ago Techtron ZA-TECH 300 and AGM 100 Ah AZO DIGITAL battery. Decent equipment, but only time will tell. User reviews are flattering. Techtron is not manufactured in Poland, just to be clear. They produce in China, there is info on the housing and instructions. The importer is Volt Polska commissioned by Techtron. They apparently cooperate, but Techtron has much better equipment than Volt Polska. The weight itself already shows the difference, the Techtron 6 kg and the Volt 4.2 kg, the parameters also.

I can confirm that the first za-tech model 500W power supply, purchased in 2015, is still working and connected to the network 24/7.
Also, my opinion about Techtron is very positive and the equipment is cool.

I'm wondering whether to preventively replace it with a new one and use the old one for less important power supply.
Because 8 years is quite a long period of operation for this type of electronics (at least I think so), and I wouldn't want something to happen at a critical moment.
Maybe it will work for a few more years, but who knows.

I'm wondering whether to use a power supply with the same power:

Or something bigger and try to connect a refrigerator with a new type of compressor (inverter).
It looks like 700W would be enough for me:

So I'm browsing the forum and looking for information...

>>20310208 Does anyone know what voltage on the battery the Techtron charges to, and what voltage the Volt or Kemot charges to? Something writes that Volt has a max of 13.8V and they recommend AGM batteries. As far as I know, AGMs are charged up to 14.4-14.7V. The Kemot, on the other hand, charges to 14.5V. I'm thinking of buying and connecting the Volt to a regular lead-acid car battery, which is why I'm asking about the voltage, because in the Volt's manual they advise against such a connection.

Jan-Osik · Answer

The za-tech Techtron uninterruptible power supply has two voltages, one equalising (or whatever it's called there) and this is over 14V (in my case it was something around 14.4-5V) and then goes to the backup voltage (around 13.6V), which is as it should be.

Choosing a car battery is probably not a good choice. Read and watch the video
