Suggestion about Power Distribution and Protection box

[solar pv]

Hi Can anyone suggest me that this model is right or not

Details:
Power box will be chip borad made
I need Ups because here electricity goes after 1 hours and my ups have 3.30 hours back up with computer.

I want to install circuit breaker in the box due we live on rental home so have to move sometime in new house there are not circuit breakers so that's why I want to install circuit breaker

Or I need anything which can cut power to ups if voltage drops to 200v here voltages are 220v

I dont want to use AVR(Automatic Voltage regulator) here voltages are good but last day due to voltage spikes my ups control kit burnt, ups fuse also burnt but It could not protect kit.

Please tell me anything which make my ups and power box safe against low voltage spikes
Please also tell what type of circuit I should use

I will also install Mppt Charge controller to charge battery from solar also and will also install 3 digital voltage meter I want to my box perfect

I know that now computer power supply is very good against voltage spikes it has built in surge protector but for power first need to go to ups then computer

You have several problems here. #1, voltage spikes, these are "cured " by putting Zenamic or such like across the line. These are voltage dependent resistors, that go low resistance for a voltage overload. Their problem is that they will soak up large surges, provide they don't last too long. They are normally rated for pulses of up to 50 microseconds length. If you use a contactor or relay to try and disconnect an over voltage supply, they take 100 milliseconds or more to operate, so you will always have a hole in the protection regime. it should be possible to switch a triac on with a very low AC mains load (5 ohms?) if the device and resistor is mounted on a heat sink, it would protect for a few seconds or so.
To protect against brownouts (lights go brown - low voltage), you need to make a window detector, powered from you UPS which monitors the incoming AC and powers a relay to switch of the incoming mains if the voltage is too low or high.

Thanks for your help, can you please tell me any devices or if I need window detector then I can buy, I am not a electrician, due to my interest I just voltage meter and some tools, I even did not about Voltage, Watt, Amp, so can you define in a way I go to market and purchase equipment for my model box
