Assuming I'm designing the system and need an Scc that would be suitable for the system, jow do i determine the Vmax of the Scc as well as its Icc(rated)?. Again, how would you account for the total power of an electric iron when sizing the inverter considering the surge power it produces?

Can off grid system function without battery storage backup

The AC CB should be placed after the ATS, because if there is a leakage the ATS will switch to grid, you don't want that.

Hi Sir. Thank you for this amazing content. Please can I follow the same procedure for a larger system? 600KW. Secondly, is your inverter in this video not oversized? will it work at best performance?

Hi brother ! why we need to use BMS for battery systems.

Please how did you determine the system voltage of 48V used in the calculation?, Is it written on the nameplate/specification sheet of the PV panels?. Thank you very much

Quite interesting and illustrative material. However, let me comment on two matters. Firstly, a 3kW inverter powered by 1,5 kWp PV array does not appear to be a good match. It is said that PV array power should rather be higher than power of an inverter. Secondly, the total nominal voltage of PV array should be adequate to the inverter starting voltage i.e. it should have been considerably higher unless the array works in very sunny good conditions for most of the day.

Hi, I would like to ask where does the 1.3 coming from?

What is that 1.3 you have multiplied to get the inverter size

Please share a clear circuit diagram

Great video! My question though when sizing panels, don't you need to up size a bit to be able to run your full load during the day and charge batteries before night load?

Very complicated on how to size the battery

Simply the best I have seen

Excellent explanation. We will be greatful, if u can give us a presentation on inside the Hybrid Inverter Circuit diagram to understand how load shearing is happening by grid and solar simultaneously.

How to size an AC breaker after the AC mains isolator switch?

Good guide dude!

Thanks

Calculation of DC CB#03 makes me wonder. Your CB#03 is of 62.5 amps for a 48 volt, 3 kW system. I have been working in solar field, and I have seen people install a 125 amp breaker for 48 volt, 10 kW system, which works perfectly fine. Using your method of calculation, 48 volt, 10kW system needs a CB rated 208 amps. Please clarify. Thank you.

Great, but what if i want only some of the load on battery for an hr or two, incase of shutdown from grid at night....

I think it makes sense to partition your system into multiple parts. I guess one smaller battery cycle for the main important things like computer, wifi, light, fan. And one for the nice to have like washing machine, water heater, microwave that can run out of power. Fridges belong to the later because even without power they can hold temperature cold enough for 12 hours (unless your freezer has a lot of meat in it ). One for all seems pretty lazy and not cost efficient.

Your Fridge is way to consuming and need a replacement with a new model, 2.5 kwh per day was 30 years ago. A modern Samsung is official specified by 0.6 kwh per day

Thanks well done

can you share these training materails in ppts or pdf please

Wow po ❤❤

Great Video, where can I find the documents used?

this diagram is compatible with Hybrid off-grid setup?

Thanks for the insight provided

Much appreciated, you makes it so much easier to understand

is there any textbooks or technical writings you could recommend

My menu has none of those options

Is this run by Allen Ng

I have a question. We divided the electrical kWh by sun hour that doesn't take solar panel efficiency into account. Is that correct?

Don't we need a battery charge controller in hybrid system to charge the battery from PV pannels?

why do you multiply by1.3?

Just found this while researching solar setup, great presentation many thanks

Hello please where did you get 1.3

But in a real sense, can four 380-watt solar panels fully charge the 4 batteries and still supply the house with the daily consumption?

I think it would be safer to size your circuit breakers 25% more than its AC output if you use the National Electrical Code safety design regulations in case of an overcurrent scenario.

@OliverJayUA-cam Like other videos on YT on this subject you FORGET one ESSENTIAL aspect of calculating the correct battery bank sizing: EACH BATTERY in the bank, not just the inverter, must be able to supply the short-term PEAK power demands. Lead-acid batteries are not so good at this as Li-ion.

Excellent tutorial.

Wow. Where's this place?

😊

Why are you multiplying by 1.3 in PV sizing

good tutorial

Why would you need such a high voltage coming from your panels?
