Question How does an inverter and solar charge controller synchronize to properly regulate charging current from both the grid and external solar charge controller going into one battery bank? I really need help
I am of a different opinion please. Depth of discharge for instance let us assume 70% as specified by the manufacturer should be used in the final stage of battery sizing i.e 70% tells us that, after you've obtained your calculation as 168.125Ah, add 70% of 168.125Ah. I mean 168.125+117.6875=385.813Ah. This is approximately 400Ah capacity battery. So you go for 400Ah battery not 200Ah.... Again, you ought to have considered the effects of temperature on the battery(as specified by the manufacturer) as well as efficiency of charging and discharging (as specified) and used them in your calculation
@@Le_vis254 That's what i was going to point out... For me this sizing process is incomplete. In the intro he started talking about days of autonomy...then that was not taken into consideration in the final result....Battery efficiency as well wasn't taken into consideration...hope there's a third video coming up
@@wenzydemar4406 Of course yes, I think he'll upload a new video to correct the slight mistakes made.. He's a great teacher and one of the best interms of explanation
Hello sir,thanks for the video..I am currently watching From Warri...sir,in one of your video on sizing of battery,you used the run time,and temperature differences of the battery.. please what's the difference between that one and this one?
Please sir,can I used the same hour for the calculations instead of individual hour.assuming my total load is 100watts,can I multiply it by 5hours as my total energy consumption
Great teaching, just a question. How do you calculate the DOD for the batteries? Where is 50% dod, 70% DOD coming from? Is it from the manufacturer? Is it already set in the Charge controller? I would appreciate your response.
Thank you very much for the knowledge shared. Can we interpret that 200ah battery with 24v inverter could run for a day if the load is within 2600whr? Also, is it adequate to rely on the information around equipment to ascertain energy consumption of the equipment, or is there any other way of getting this info?
You can check the equipment to see the power rating or daily energy consumption. You can also use an energy meter to know the energy consumption of the electrical equipment
Thank you so much I newly subscribed to your channel My queation here is , After all the calculation you got 24volts/200ah battery .so how many of it (the battery) will give or serve the Energy demand of 2,542whr.??
2 units of 200AH connected in series gives 200AH/24v to give you the whr calculated in the video. The battery bank will supply the reactive power and power losses in the inverter and also considering 50% battery usage, which is enough to supply the whr calculated in the example.
You teach very well , but I think you have to review your teaching very well Because am in a doubt that 200AH batteries cannot accommodate such load . Another thing is that you did not consider the battery efficiency and also the materials like cables loses as well For me all you have to do is to divide the t.d.p.c by 12 which is the single battery voltage you can see, then what ever it gives you is your total Batery AH then you divide it by the amp rating of your individual battery to get how manny number of battery required

Awesome Training Section 🥰🙏
Very educative
🙏
Please give your number 🙏🏻 @@Solarwattng
How about "days of autonomy"?
I like the way you lecture sir
Glad to hear that
I am happy to listened to your video. Great job. Watching from Ikorodu Lagos
wow! Thanks 🙏
Please talk more about how to do the electrical connection of the appliances the client want to use
Alright! I will by God's grace. Thanks for your suggestions
Good evening boss... I'm watching you from Lagos..
Thank you for your great knowledge 🙏
Thanks you #Boss, God bless you for the infor
Thanks
Thankyou sir
👍
very detailed explanations. keep up the good work
Thanks... I'm grateful
What is the DOD of lithium battery
Well explained...👏👏👏
Teaching good my brother. Watching u from india Rajasthan Jaipur
Thanks and welcome

Pls sir i think you can help add the calculation omitted as u have said above .
I will be glad if you do for me .
Thanks
Thank you boss
I really appreciate it sir
Thank brother, I'm Jeremie Gbadyu , watching from Liberia 🇱🇷
Thanks for watching
Great
i understand now . thank you am from South Africa
Thanks
Say my days of autonomy are 2, how do I include it in the calculation?
Multiply your AH value by the days of autonomy, for instance since his days of autonomy is 1 the Ah value remain same
Your analysis is great 👍

Hello sir,thanks for the video..I am currently watching From Warri...sir,in one of your video on sizing of battery,you used the run time,and temperature differences of the battery.. please what's the difference between that one and this one?
My God will bless u, am learning alot❤❤❤
Amen... Thanks 🙏🙏
Thanks for your lecture. I have a 500wts /SAA500A inverter. What is the number of panels of 100wts can be used for 2x12v 75Ah. Thankyou once more
What if the nominal system voltage is 48 volts? Do you divide it by 48v? Well done so far
Can't find the video on Load analysis table
Many thanks!
Praise the Lord!

Good morning brother I am watching you form Liberia
Watch from kaduna
🙏
Beautiful as expected.
Thanks
Good work, but you did not mention the days of autonomy in your steps. Is to divide or multiply by the T.D.E.C
I would assume that it should be multiple because if the total energy consumption for one day is 2542wh then two days would be 2542*2 = 5084wh
Please sir,can I used the same hour for the calculations instead of individual hour.assuming my total load is 100watts,can I multiply it by 5hours as my total energy consumption
Yes... if you are using all the loads at the same time.
@Solarwattng okay sir,but what if am not using them at the same time,but at different period,you know some won't be work at all doing daytime sir
Please how would you know the inverter efficiency
Check the manufacturer manual or specification sheet
Well done sir
How do you get 24v/2000Ah?
Thanks brother but let's assume we're using dc only in the system, how can we size the battery bank without inverter efficiency?
just don't divide it by the 0.9. (rather by 1) since there arent any losses
Can the Growatt SPF 5000 ES charge a 15kwh battery with a 4950 watt panel?
Yes it can.
It would take 3-4hrs depending on your DOD
that is great to know. meaning i dont have to increase the solar arrray yet until i increase the inverter size...@@peterakoh3432
We didn't use the autonomy. what if it is two days?
How about temperature efficiency you didn't include that sir
Great teaching, just a question. How do you calculate the DOD for the batteries? Where is 50% dod, 70% DOD coming from? Is it from the manufacturer? Is it already set in the Charge controller? I would appreciate your response.
you basically have to decide the DOD that is suitable for you based on the number of cycles you want your battery to do during it's life span
What if I'm not on an inverter?
How will i know the inverter efficiency?
Check the specification sheet of the inverter
How do you find your total daily energy consumption
Thank you very much for the knowledge shared.
Can we interpret that 200ah battery with 24v inverter could run for a day if the load is within 2600whr?

HI, I am watching from Curacao.
Thank you sir for good teaching. Sir is there 24v battery of 200Ah?
You will connect 2 units of 200AH/12v battery in series to get 200AH/24v battery bank
@@michaelakomolafe9249why was 24 volts considered instead of 12volts on the nominal system voltage in the final calculation?
Thank you!
Thanks

Is the battery lithium / lead acid

Another accurate calculation. Well done!

You teach very well , but I think you have to review your teaching very well
Because am in a doubt that 200AH batteries cannot accommodate such load .

Another question is let's assume the days of autonomy is more that one day
❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤
Thanks
What a superb explanation. Kudos 👏. Can i get your contact pls sir.
Thanks... 0810 878 1450
You forget the day of autonomy and the battery temperature.
In this lesson, u didn't take days of autonomy into consideration in ur calculations
He clearly did at the earlier half of the video, where he said for this calculation he'll use just 1 day of autonomy
Your contact please!
Sir can i have your number i have an important question to ask
I love your video and am learning alot from you sir.... please how can I be in touch with you on whatsapp sir
