I bought my AVR directly from china for less than 1800 cedis. Mine is analogue screen cus that's what they had with 90% efficiency compared to 80% for their digital ones. Same 20kva capacity. Had I known, I would have gone for 30kv version for maximum load. They said you shouldn't use more than 2/3 it's capacity for safe operation. Using something like Aircon+ washer + fridge takes about all that's left. Each appliance should be calculated with 3x it's load. So 20kva leaves me just about ~6kw load at a time. I should add that my solar Growatt inverter is programmed to alarm at less than 170v which I guess it's the minimum safest voltage. ECG power is very unstable so this happens quite often hence the more the need for AVR. My thoughts, most people spend too much on the build without these absolute essentials. My goal is to eventually install an erv for fresh air flow.
Asher and Gad thanks for your sharings on Electrical Installation, makes so much sense. I hope your Consultancy really prospers you both, for the information you share you deserve it.
Thanks again for another great video. Quick question, can 220V AVR protect both 110V and 220V appliances? My house is wired with both 110V and 220V. Thx
Good Evening : I am interested in moving to Ghana and would like to speak with you regarding having my home built similar to. that beautiful home that you have built. How do we talk to get my home built?
My AVR (20kVA) single phase was 6,000GHs - this was purchased 12months ago Just asked about a 30kVA single phase AVR recently and was quoted - 9,000GHs
SPD protects the installation from inside (indirect strikes) while Lightning arrester protects the equipment from outside (direct strikes) . SPD protects the system from Lightning, switching transients, surges, etc. Lightning arrester is mainly used for direct Lightning strikes this is also called the AIR TERMINATION ROD. Refer to my Lightning protection video referenced in this video within the first 5mins, click the link and watch
Is unfortunate you didn't buy DB with SPD on it. It was available at the time you bought yours cos l did my wiring a month before you. I don't know, but it seems you don't know GH market well when it comes to electricity. Anyway, l have AVR and a setup & down transformer since my house is 220v and 110v.
Also you do not know when I did my wiring. You assume you see a video means I am doing the work at that time is INCORRECT. Many videos are done well in advance including this one, which I recorded weeks ago
@@kingstal90 l have been following you from day one. When you were posting your wiring videos you were giving us weekly updates with stamped dates that's why I knew l did my wiring a month before you.
Solar normally comes with SPD by default. You wouldn't need the AVR as much as the Solar is just your home so the voltage fluctuations should be minimal

I am sold on all your recommendations. I knew that there was a lot of power interruption's, but did not know the power flow was so erratic.

Can you please share a link to where you bought yours from?

Thanks very much
Always a pleasure to watch your channel. Very educative.
Thanks
What should be the standard input voltage and output voltage of an avr
Great video, definitely will make sure to get both on my list! Thank you❤️🙏🏽
Nice video
Great video
Glad you enjoyed it
Hello please where did you buy your AVR and can i get the referral please?
Nice one massa. I’m learning a lot from you.
You’re Welcome
Thanks again for another great video. Quick question, can 220V AVR protect both 110V and 220V appliances? My house is wired with both 110V and 220V. Thx
Sure
All depends on where you connect the AVR into tha system. You can connect it before the step down transformer
@@kingstal90 My 110V transformer source power from the 220V fuse box so hopefully it will work. Thank you

Where can I get AVR IN ACCRA
A little confused, isn’t the AVR enough to slow down an incoming high surge voltage? Why do you need SPD as well …
Electrical Engineering
Voltage Fluctuation is different from: transients and the effects of indirect lightning strikes
What was the cost of the AVR and SPD respectively?
My AVR (20kVA) single phase was 6,000GHs - this was purchased 12months ago
Just asked about a 30kVA single phase AVR recently and was quoted - 9,000GHs
Why do you have single phase avr when your house has 3 phase from ecg?
Should you need SPD if you have already installed lighting arrester?
SPD protects the installation from inside (indirect strikes) while Lightning arrester protects the equipment from outside (direct strikes) . SPD protects the system from Lightning, switching transients, surges, etc. Lightning arrester is mainly used for direct Lightning strikes this is also called the AIR TERMINATION ROD.

I said it was not available from that particular seller. I didn't say it is not available in the whole Ghana Market.

@yaa baby can you link me to a seller that I can get a SPD… thanks

@@derekg3230 which part of GH is your property?
Please can we have the details of the AVR seller?

Tell him Kingsley gave you his number
@@kingstal90 thank you very much...
do you need both systems even with solar ?? i appreciate your response.
