Very good tutorial. Thanks for your time preparing it. It is worth mentioning that hybrid inverters also has minimum and maximum Vdc range. E.g., 120-450Vdc. It means they will not work with low voltage from small panel array. So if your inverter is min 120Vdc and you connect only 2 panels with 50Voc each, it will not work.
Very good explanation of how to calculate a simple low energy system. Mine has been running for approximately 4-5 years without any issues. But due to the lack of summer weather here in the UK the system only runs for around 7 months of the year.👍

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.
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?
Hi Oliver! In string calculation you did not considered Noct in respect of Vmp(min) to Vmp(max.) I also recommend to explain module Voc minimum to maximum value at Normal operating cell conditions as per site calculations. Otherwise overall is good for beginners 🙏
Hello Sir, For the Surge protection, take a look at the Uc and Up values of your SPD. Uc is the maximum continuous operating voltage, if the SPD senses a voltage above this, it becomes active. Up, on the other hand, is the maximum voltage across the SPD when it is active. Up is selected as such that it is below the overvoltage withstand capability of the loads. A typical DC SPD has a Uc of around 500 VDC and a Up of ~2kV. As far as I know, there are 3 types, classified according to the frequency of the surge. Type 1 is installed near the panels for protection against lightning. Type 2 is installed between the source and the load, for added protection. Type 3 is installed near the load to redirect any residual surges - good for loads that are very sensitive to fluctuations. There are SPDs that can cater for both Type 1 and Type 2.

wonderful explanation @oliver jay. my question basically is , how did you come about 1.3in the formular for PV Power i,e step 2 (sizing of solar PV panels). Thanks.
It's because of the performance ratio of the installation site. For example, in Brazil, we have approximately 80% solar efficiency. So, the calculation would be 1/0.8 = 1.25.
hello thank you for this amazing lecture can you tell us more about the solar panels not all the pannels have voc 48.8 volt what to search for the panels specification in my system?
Hello sir, aside from the Voc, another important spec we should consider is the watt capacity of the PV panel. It helps to know several options for panels, inverters, and batteries so you can easily mix and match the items depending on your calculation. Easiest would be to seek the help of solar equipment supplier as they can easily recommend specific panels, inverters, or batteries for your project.
hei thanks for the insight..i wanted to know why it is written AC IN at the INVETER yet we are transferring excess power to the grid during day time....or does the point has an input/output option for charging during night and transferring to grid during day time
Hi bro, this is an example of a hybrid on-grid setup. Depending on the setting, the system switches between utility power and battery. For example, during brownouts or blackouts, the system can switch to using the batteries. Or, if the battery is depleted, it can switch to utility power.
Hi Oliver. Thanks for posting this information. My sister lives in Aden where the electricity is intermittent (on 3 hours off 3 hours) and a hybrid system may be the ideal solution. 1. Difficult to do load analysis because they didn't have ongoing grid supply. 2. Could do with a system that powers 2 air conditioning units (2600w) and the daily consumption could be around 50kwh. 3. Would need a system that stores about 5 hours for use with air conditioning over night. Battery size 16kw? 4. Hybrid inverter 8kw? 5. 24x Solar panels 330w? 6. Would like the system run via grid and use the solar as backup Any pointers you can give me would be greatly appreciated
Hello sir, i agree, hybrid should be the ideal setup if the grid us intermittent. i did a quick computation and yours should be ok. I believe you used sun peak hours of around 8-9hrs, correct? I think it's quite sunny in Aden but I dont have any definitive value on the sun peak hours so we'll leave it as you have calculated. Battery should be more than enough, should be at least 3 strings and 4 series of 12V/250Ah batteries. Inverter type fridge and AC are quite difficult to estimate since their power consumption varies throughout the day and affected by many factors.
@@southernrealist5789 Hello sir, Hybrid inverter 8kw Battery bank 3 strings/4 series of 12V/259Ah battery (Total = 48V/750Ah) For inverter, i'm not sure what is available in Aden. You may check the brands: Solas, Sofar, Solax, SMA, Huawei, etc.
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.
Thanks for the great tutorial. By the way, do you think DC isolator is needed? I can simply isolate the panels from the system with the DC circuit breaker.
Good day din lakay! Appreciate the comment. For sizing purposes, yes i believe this is applicable to DEYE or any other hybrid inverter. Just need to double check the installation and operations manual or consult your supplier should you run into problems during the installation.
Hi sir, why is the there a need for a DC isolator switch in between the solar panel and hybrid inverter when there is already a DC circuit breaker present?
Hello sir, you can actually do without one. It is just an added protection. It also is for convenience, in case you need to repair something on the inverter side, you can cut the line from the PV panel through the isolator.
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?
I have a solar hybrid inverter with an inbuilt pwm charge controller. I would like to change to an mppt controller, but I don't want to loose the function of the inverter switching between grid and solar. Is there a way to use an mppt controller and have the inverter retain this ability so it can reduce my bills?
I have a 5kw inverter with 12x435watt panels. Could only add 4x100ah batteries due to affordability. Usage is 50kw a day. Where do I spend the next money to upgrade? More panels or more batteries?
Hello Sir, it depends on priority. If you have critical appliances in your house that you need to power up for a long time then upgrade your batteries. If none, upgrade your panels and monetize your harvest by giving your power back to the grid (assuming you have net metering). Batteries are quite expensive to maintain. Just my opinion. Cheers!
Hello sir, the wiring for the ATS is as shown on the diagram in the last slide of the video. On one side, you will need to connect it to your normal power (utility) and on the other side your reserve power (battery and inverter). Best to consult the datasheet of your chosen ATS.
Hi Velly, same approach as with Lead Acid batteries. Only difference is the Depth of Discharge (lithium battery DOD is around 90+%). Plus, each lithium cell comes in a lower voltage of around 3.2V/cell typically.
@@vellyyt3572 hello bro, technically we can to keep our solar power system running even during power interruptions but we should not do it due to safety reasons.

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.
Hello sir, yes you can do so by increasing the number of operating hours when calculating for the battery capacity. This one is a simplified version assuming that the sun always shines the next day hence, only caters for a day's worth of autonomy. 😊
It's because of the performance ratio of the installation site. For example, in Brazil, we have approximately 80% solar efficiency. So, the calculation would be 1/0.8 = 1.25.
Nice.. Sir i have a question.. I have a 1.2kw hybrid inverter 12v and 480w solar panel.. Hybrid set up. 200 ah battery .is this set up can run my 1.5hp aircon?

Sir, planning to build 32650 cells in 48v range 96ah. So, in total i got 16s 16p then will use 48v 16s 100ah bms. My max continuous discharge current is 240A could this Ampere be fit in my 5kw HOG inverter?
Hello Sir, may I check with you what type of load are you planning to plug into your HOG? What is the total power of your load? I believe 240A discharge current is too high.
@@OliverJayRUclips AC =690W .75hp dual inverter Fans =60W 3pcs Lights =5W 3pcs Laptop =90W All are running 4hrs. But not at the same time. Got 3,885 Wh. May I know what is the max continuous discharge current for/meaning? Btw, I really caught up by your vids, it's way too easy to comprehend compared to others. Keep it up! Also, I can't find max input current of Sako Sunon 5kw HOG is it the Amp rating of MPPT inside?
Hello Sir, i believe your battery set-up should be fine and will be able to support your load. Lithium batteries will have higher depth of discharge and efficiency than gel batteries. From the numbers, i guess you are using 3V 6000mAh per cell or somewhere around that. The max discharge current is a battery specification defined by manufacturers to prevent over diacharging the batteries which will damage it.. The max discharge current of 240A is still a long way to go so your still ok. And yes, you can use your 5kw HOG for this. Hope this helps and I appreciate your feedback.
Good evening, just got my Sako Sunon 3kw 24v. Then at the datasheet I'm looking for its Max. Input current, but there's none. It has a Max. Solar Charge Current= 80A is that it? Btw, here's the link: sako-solarengineering.com/sunon-plus-series-hybrid-solar-inverter-high-frequency/
Why do u multiply by 1.3 for the pv power? Also what if your battery requirement was 286.27Ah and you only have 250Ah rating batteries... would you do a series parallel connection and how would you go about it?
It's because of the performance ratio of the installation site. For example, in Brazil, we have approximately 80% solar efficiency. So, the calculation would be 1/0.8 = 1.25.
Hey I have a ? If u don't mind Can I have 1 set of 8 100 watt panels in seires making it 165 volt and 5amps N other set in parallel making it 40 amps n 20 volt ? And connect them all together so my battery will charge full .. I notice my batter keep dying fast since I brought this mpp pip 3024gk . I try having 1 set making it 340 volt n still my battery turn off around 12am. What is ur take on that ? Thank you for ur time !!!
Hello bro, I checked your inverter specs. Max PV input is 500V and Max charging current is 80A. With your current panel qty, i think it is not fully optimized. If you connect all 16 PV panels in series, that only gives you 5A 320V 1600W. If you go with 2 strings of 8 panels in series, you get 10A and 160V 1600W. Both setups give you a lot of room to improve. To optimize your setup, you may add more PV panels. 3 strings of 8 x 100W panels will give you 15A 160V 2400W. You can also have 4 strings of 8 x 100W for a PV array output of 20A 160V 3200W. Either way will improve your battery charging power.

@@kissofdeath9660 Hello sir, tried calculating, your setup is fine (2 x strings of 8 x Panels in series, plus 24V 225Ah battery bank). There are other factors that drain your battery bank, for example, high load consumption, cloudy skies can also affect battery charging.
Hello sir, if you are connecting 2 different sets of PV arrays in parallel, the inverter will see it as as one input only. You may compute the total voltage/current using the series-parallel computation. As much as you can, you may want to avoid combining different PV panels or arrays as this can be a bit of a headache during maintenance/repairs.
@@OliverJayRUclipsthanks for your reply I mean , the PV volt in your example is 195.2 Vdc while the battery is 48 Vdc. So, can the inverter support or Handel these different volts together?
Hello sir I personally haven't tried using one but i'm thinking if building a small setup with a balancer when I get back home...currently stuck due to this pandemic. But, I do see a lot of battery balancers available in the market, it's just a matter of picking which one. If on a budget, you can do it manually by swapping battery positions every now and then.
Hello maam, madami po kasing hybrid inverters. Best to choose the one that fits your specs and available locally (and sold by trusted suppliers) for easy warranty claims. Some brands that I know of are East and MPP solar, and solax.

This is helpful to build an aquaponics powered with solar panels.
Yes sir. I would also want to build an aquaponics when I go back home. Cheers!
Might consider the days of autonomy in sizing the battery battery bank calculation.
Hello sir, yes you can do so by increasing the number of operating hours when calculating for the battery capacity. This one is a simplified version assuming that the sun always shines the next day hence, only caters for a day's worth of autonomy. 😊
this diagram is compatible with Hybrid off-grid setup?
Galing!
I will make my own hybrid design, Sir and if you may please review it for me.
Thanks.
You are welcome sir and Good luck on your build.
This is a renewal energy ... love the nature keep safe
Thank you sis, you too!
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.
Why did you multiply it by 1.3 for the PV panel sizing?
It's because of the performance ratio of the installation site. For example, in Brazil, we have approximately 80% solar efficiency. So, the calculation would be 1/0.8 = 1.25.
Thanks for sharing your knowledge 👍
Nice.. Sir i have a question.. I have a 1.2kw hybrid inverter 12v and 480w solar panel.. Hybrid set up. 200 ah battery .is this set up can run my 1.5hp aircon?
hi sir, can i have the reference on this video on a pdf form or article, were conducting research about this and it will be so helpful if we have the reference on this. thank you in advance
This is very helpful.Thanks for sharing.
Glad it was helpful!
Thanks so much, very good explanation.👍
You are welcome!
Clear explanation. Thanks for this
Glad it was helpful!
Don't we need a battery charge controller in hybrid system to charge the battery from PV pannels?
No need, hybrid has built in battery charge controller
Sir, planning to build 32650 cells in 48v range 96ah. So, in total i got 16s 16p then will use 48v 16s 100ah bms. My max continuous discharge current is 240A could this Ampere be fit in my 5kw HOG inverter?
Hello Sir, may I check with you what type of load are you planning to plug into your HOG? What is the total power of your load? I believe 240A discharge current is too high.
@@OliverJayRUclips AC =690W .75hp dual inverter
Fans =60W 3pcs
Lights =5W 3pcs
Laptop =90W
All are running 4hrs. But not at the same time. Got 3,885 Wh. May I know what is the max continuous discharge current for/meaning? Btw, I really caught up by your vids, it's way too easy to comprehend compared to others. Keep it up! Also, I can't find max input current of Sako Sunon 5kw HOG is it the Amp rating of MPPT inside?
Hello Sir, i believe your battery set-up should be fine and will be able to support your load. Lithium batteries will have higher depth of discharge and efficiency than gel batteries. From the numbers, i guess you are using 3V 6000mAh per cell or somewhere around that.
The max discharge current is a battery specification defined by manufacturers to prevent over diacharging the batteries which will damage it.. The max discharge current of 240A is still a long way to go so your still ok.
And yes, you can use your 5kw HOG for this.
Hope this helps and I appreciate your feedback.
Good evening, just got my Sako Sunon 3kw 24v. Then at the datasheet I'm looking for its Max. Input current, but there's none. It has a Max. Solar Charge Current= 80A is that it? Btw, here's the link: sako-solarengineering.com/sunon-plus-series-hybrid-solar-inverter-high-frequency/
Hello Sir, yes, I think it is. The max solar charge current is the max current from the PV panels going to your hybrid inverter.
Why do u multiply by 1.3 for the pv power? Also what if your battery requirement was 286.27Ah and you only have 250Ah rating batteries... would you do a series parallel connection and how would you go about it?
It's because of the performance ratio of the installation site. For example, in Brazil, we have approximately 80% solar efficiency. So, the calculation would be 1/0.8 = 1.25.
Thanks 👍
a nice tutorial sirr.. thankyu sir.
on which software yu make these slides.......
it's just powerpoint sir
Hey I have a ? If u don't mind
Can I have 1 set of 8 100 watt panels in seires making it 165 volt and 5amps
N other set in parallel making it 40 amps n 20 volt ?
And connect them all together so my battery will charge full ..
I notice my batter keep dying fast since I brought this mpp pip 3024gk . I try having 1 set making it 340 volt n still my battery turn off around 12am.
What is ur take on that ? Thank you for ur time !!!
Hello bro, can you please give me your PV panel specs? I'll check on my end. Cheers!
@@OliverJayRUclips 5amps 20 volt 100 watt.( I have 16 100 watt )
Hello bro, I checked your inverter specs. Max PV input is 500V and Max charging current is 80A. With your current panel qty, i think it is not fully optimized. If you connect all 16 PV panels in series, that only gives you 5A 320V 1600W. If you go with 2 strings of 8 panels in series, you get 10A and 160V 1600W. Both setups give you a lot of room to improve.
To optimize your setup, you may add more PV panels. 3 strings of 8 x 100W panels will give you 15A 160V 2400W. You can also have 4 strings of 8 x 100W for a PV array output of 20A 160V 3200W. Either way will improve your battery charging power.
@@OliverJayRUclips thxz but I just find out that my battery bank is only 225amps since I have 24 system now... I use to have 12volt system n get 450amp .. I have 4 6 volt trojan 105 re battery at 225amp each... but wen I make them 24volt system it will become 24 volt at 225 amp right ? I think thats the reason why my power turn off around 12 to 2 am .. am I right ?
What you think I should have wired all of them in 1 set to make it 5amp at 320volt or 2 or 3 set? If 3 set that mean I should buy 8 100 watt panles more. Sum1 told me to get two set of 12 100 watt panles to make it 240 volt at 5amp each do u agree with that ?
P.s. thank you for ur time
@@kissofdeath9660 Hello sir, tried calculating, your setup is fine (2 x strings of 8 x Panels in series, plus 24V 225Ah battery bank).
There are other factors that drain your battery bank, for example, high load consumption, cloudy skies can also affect battery charging.
tutorial for sizing hybrid solar wind power system, hybrid inverter?
maybe someday sir. thanks for the suggestion.
Awesome explanation
Thank you sir!
good day. pwede po ba gamiting ang hybrid inverter sa tie-grid system na wala nang battery bank?
salamat po
Hello sir, I think pwede naman po. Best is to check with your supplier para sigurado.
Why do we multiply by 1.3 to get PV power
We multiply by 1.3 to compensate for the losses (i.e. cloudy day). You may increase or decrease this factor if you like.
Sir pano in actual saan magconnect ng AC in at AC out from inverter? Dun ba yun sa main distribution panel? Please advise...Tnx u.
hello sir, you can refer to this video. Actual set-up po yung pinakita. hope this helps :)
Hi, possible to share the soft copy of the presentation?
Can the inverter handle two different voltages from PV and battery bank?
Hello sir, if you are connecting 2 different sets of PV arrays in parallel, the inverter will see it as as one input only. You may compute the total voltage/current using the series-parallel computation.
As much as you can, you may want to avoid combining different PV panels or arrays as this can be a bit of a headache during maintenance/repairs.
@@OliverJayRUclipsthanks for your reply
I mean , the PV volt in your example is 195.2 Vdc while the battery is 48 Vdc.
So, can the inverter support or Handel these different volts together?
@@abdrahmangalal7415 yes sir, the inverter will "step-down" this voltage to be suitable for your battery bank.
@@OliverJayRUclips thank you sir
Very well explained.
Glad it was helpful!
Sir how do you balance the batteries?
Hello sir I personally haven't tried using one but i'm thinking if building a small setup with a balancer when I get back home...currently stuck due to this pandemic. But, I do see a lot of battery balancers available in the market, it's just a matter of picking which one.
If on a budget, you can do it manually by swapping battery positions every now and then.
If you put them in series for a while they will balance
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?
Excellent video thank you
Thank you sir
Thanks 👍 you 💗💞
Welcome 😊
Hi Sir, May mairerecommend po ba kayong brand ng Hybrid inverter, for home use lang sana kagaya ng set-up nyo sa video.. thanks
Up
Hello maam, madami po kasing hybrid inverters. Best to choose the one that fits your specs and available locally (and sold by trusted suppliers) for easy warranty claims. Some brands that I know of are East and MPP solar, and solax.
@@OliverJayRUclips Hi Sir, Regarding sa battery bank 1 string and 4 series connection. meaning 4 pcs na 250Ah and iseseries? thanks

Connected ba yang AC out mo sa grid ulit? Di ko kabisado logo hehehe..
Yes sir
how about kung walang electrical bill po?
need bang icompute ung electrical consumtion sa buong araw (24 hours) of sa umaga lang po?
this is helpul to build friend thank you for sharing
No problem 👍
Very informative video!
Glad it was helpful!
Thank you sir.
NP sir! You're welcome!
Where does the 1.3 come from?
Hello sir, 1.3 means adding 30% to the PV capacity. This is to compensate the not so optimum conditions such as cloudy skies.
Sir para saan po yung 1.3 sa sizing of solar pv. Ano ang purpose noon? Salamat
For buffer capacity sir in case hindi masyadong maaraw. Yung 1.3 effectively adds 30% sa pv capacity. You can adjust this as you want.
Which software is that?
Hi, the schematic was done in visio.
good tutorial
how do I calculate the side of circuit breaker?
I believe he did explain both just rewatch and he goes over both DC and AC circuit Breakers
Just scan through video and see the red boxes pop up around the DC CB #1, DC CB #2 and AC CB on the expanded diagram
thankyou very very much
You are welcome sir!
Thanks well done
