Its for an ac. My whole house usage does not go above 1000 Watts in a day. I have yet to buy an ac, but when i get one in the coming months, it will be a 5 star ac sipping less than a 1000w. Only other item I have that takes 1000W is an electric iron which i hardly use.
Equipment's that run all the time will be :
* A fridge (120W)
* apc home inverter (500W)

Data sheet says it supports upto 15A output. 15A@230V = 3450W which is more than my house requires.
There's another item on their page for direct line voltage regulation. http://www.sollatek.com/products/svs20355075-wm/
I'm worried about the price though. Also didn't see it for sale anywhere here in India.
 
It doesn't do voltage regulation, right? is there anything like this that does voltage regulation?
Say i bought an ac and the voltage went up to 265V which happens sometimes for 5-10 minutes in our area. In this case it will kill power to the whole house suddenly and only the items connected to my inverter will work. Wont the ac connected get spoilt if this happens regularly?

No voltage reg- Power monitors are only recommended for houses where the supply voltage is relatively stable
The only way to do voltage reg for the whole house is through a bulky transformer based stabilizer

And while the cut off voltages are changeable- A cutoff at 255-260V is anyway recommended in which case 265V would result in power getting cutoff to the whole house
The duration to wait post power returns to normal is also modifiable so say if you keep a 1-2 min wait, your AC and other devices should stay fine

Another question somewhat related to the topic. Is there something which will stop short between the live and neutral lines on a single phase connection? Mcb is too slow. The MCB shuts off after the damage is done. Is there something that shuts off in the shortest time as possible?
 
ELCBs are much faster than MCBs
However they won't trip on a short but on a difference between live and neutral line current (i.e. scenarios where there is a live leakage somewhere)
Why do you think MCBs are slow to trip on shorts though?
A typical MCB will trip within 1/10 of a second on a short - Barely enough to result in any real risk of fire etc - What risk you reckon a 100 ms trip carries?
 
Well actually this happened long time back. After a power cut when the power came back on, there was a short in neutral and a surge protector blew up, the outlet it was connected to blew up and then the mcb tripped. So 100ms is too low or I should replace the existing one with a better branded mcb. I was thinking of putting an RCB but the mains board does not have that bus bar. It's the old wooden cover on a hole in the wall.
 
^^ i am referring to the fuse in the faulty device/appliance; surge protector in your case. it's the fuse that prevents further damage to the device. you'll need to find the fault and then replace the blown fuse. fault could be in your house wiring or the device. your MCB is doing its job properly. it'll keep on tripping if you don't fix the fault first.
 
Fuse in device didn't blow. All the neutral wires burnt out or blew into bits. Fuse will blow only if there's over voltage on live. This came through neutral via mains line straight from transformer. If i put a 25A MCB on live an a 6A MCB on the neutral will it work in such situations?

there is no such thing as a short in neutral blowing up a surge protector
You had a power surge (momentary high voltage) and the mob won't help in such cases
this is where a power line guard (like the sollatek) comes in at work
also, It does not hurt to have a spike guard for secondary protection at any outlet serving high value electronics

Ideally you should have the following at the mains if you get regular 230V at your mains
a) An MCB to safeguard excessive power draw in case of a short
2) A RCCB to safeguard against current leakge (like electrocution)
3) A voltage/spike monitor like the SOllatek

And over & above this, a good spike protector at the points where sensitive electronics are connected

- MCB on neutral is useless.

- live phases and neutral wires from transformer are first fed to mains fuse. if you have single phase electricity connection, you'll have 2 fuses. and 4 fuses for a 3 phase supply.

- live wire now goes to MCB. you can have separate MCBs to cater to different current requirements.

- i don't know how and why you got current on neutral from the transformer. here, a ground fault interrupter could've saved you, and not a faster MCB.

- you also need to look at your ground/earth wiring. this is a basic need, which can prevent shocks.

In my house, from meter it goes to a mcb on live, then there's a switch with fuses on L + N and then comes directly to another mcb inside my house. I need to make a new earthing line for my home. The old one line might be broken in some places i think.
Where can i get a fuse box? Do the fuse boxes take those glass fuses which can be replaced easily or its the single core wire?

these days you get fuses like these:

Camlock-Fuse-Holder.png

i don't know the proper name for it but here in NCR, people call it kit-kat fuse. looks like a capacitor to me.

you don't have to go for a fancy holder. this pic shows Havells' cam-lock type holder. there are lot many fakes floating around, so get yours from a reliable source. and as you can see, you can't repair a blown fuse of this type at home. you'll have to buy a new one each time.

Sorry to bump this. Got the Sollatek voltage switcher Avs30, and it uses a 500mA slow blow ceramic fuse. Where can i buy such fuses from to keep in stock. Just want 2-3 fuses. Can a glass fuse from a surge protector be used in this if i can't find ceramic one?
 
How does sollatek ac guard work? There was a 1 min power outage & it automatically switched off, so i turned it on but now nothing happens its not turning on again .
