Microtek UPS 24×7 HB Series Inverters Review – 875, 1075, 1275 – Evolutionary or Revolutionary Upgrade?

90 / 100

Microtek UPS 24×7 HB series now have a upgrade after a long time. Is it a evolutionary or revolutionary Upgrade? That’s what I intended to find out.

These new model started to come to distributors only recently, I haven’t still seen it online with retailers like Amazon or Flipkart, but it should come to them some time in the future as the older stocks run out.

As you can see from the photos, this is a big design change both inside and outside. They have changed the external design of model very much to suit a more modern approach. In the inside, they have changed the board design. Now its a completely SMD (surface mount device) board – opposed to the previous design.

The transformer is obviously made of Aluminum – so do 99% of other manufacturers. I haven’t personally seen transformers blowing up in Microtek inverters unless its put in moisture situation. But many others who don’t make Aluminum transformers without much research have blown transformers due to load.

Pros of Microtek UPS 24×7 HB series

– New Design – both inside and outside
– Only a slight increase in pricing compared to the older models.

Cons of Microtek UPS 24×7 HB series

– Only time can tell whether this new design will match the longevity and serviceability of the older model. The older model was pretty easy to service, most times we were able to change the components very easily. But this new board contains SMD’s which may be difficult to change. So you may have to change the entire board. Still Microtek has one of the best after sales service in India.
– The model name 875, 1075 or 1275 has no match with the VA (volt ampere) or Watts of the device. Sad to see Microtek following the trend set my other manufacturers like Luminous, V Guard etc. May be they had no choice since all other manufacturers do the same thing now.
– There is no model number mentioned in the front face of the inverter (may be this was a flow in the initial models) – its mentioned in the packaging and also on the back side of the inverter.

So all in all, I would say that this is kind of an evolutionary upgrade to keep up with the times.

Do checkout other reviews by me.

  1. Hey Binil, Got the HB 1275 last month since a local dealer gave at attractive price and he also said its August 2020 stock. Once installed from first day itself charging like was continuously blinking. I allowed it to charge new battery for 2 days still it was blinking. Called support who came after 1 week and said they have to change the board as it was defective. I argued with both dealer and service guys but both point each other. Microtek said like u wrote. Previous models had more components which could be changed. Now SMD models have more plug and play of bigger components. So any issues, whole compenent need to be replaced.
    Still trying my luck with returns and replacements. Lets see how it goes.

    1. They need to check the charging voltage – if upper cut off is at around 14.4V, it should be ok for new batteries – but if its an old battery, they need to lower the upper cut off voltage – I am not sure if they can set this in newer boards (it was possible in older boards).

      During the Corona period, service from all companies are lagging – here in my home town Thrissur – Microtek service engineers are only coming to the dealers or shops – they are not visiting the homes for repair.

  2. Hi Sir, Thanks for sharing your technical review on HB 1275/12V, when this model release in the Indian market?. I do not see this model in “microtekdirect” site.
    Could you please clarify on this.

    1. Dear Venu,
      It should be available with the local vendors once their old stocks are finished. Its available in my home town – Thrissur with Buff Power. I honestly don’t know why Microtek doesn’t provide updates on their website on the new products.

    1. The output voltage in normal inverter mode and ups mode will be the same when working from battery. The difference is that in normal mode, it will change to battery backup if the input voltage goes below 100v or goes above 300v. In ups mode, it will change to battery backup when input voltage goes below 170v or goes above 270v.
