Watching in Port Moresby city, Papua New Guinea. Very impressive. Currently embracing on solar sizing of small off-grid solar power systems for clients. Vital information from your lectures. Thank you for sharing the knowledge. God bless

You explain good am from Tanzania🇹🇿

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

@@Solarwattng what do you mean?

[@wenzydemar4406]

​​​@@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

[@Le_vis254]

@@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

How about "days of autonomy"?

[@chineduugwuoke6483]

Can't find the video on Load analysis table

[@okoraforremigius8748]

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

[@kennedysikaonga5921]

Teaching good my brother. Watching u from india Rajasthan Jaipur

[@Solarwattng]

Thanks and welcome

[@Solarwattng]

Thanks

[@user-ph6cp2ox7u]

Please how would you know the inverter efficiency

[@Solarwattng]

Check the manufacturer manual or specification sheet

[@LameckLuyima]

Thanks brother but let's assume we're using dc only in the system, how can we size the battery bank without inverter efficiency?

[@sogoomopariola9799]

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?

[@Solarwattng]

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

[@favouruboh5766]

How will i know the inverter efficiency?

[@Solarwattng]

Check the specification sheet of the inverter

[@emmanuelpeprah1453]

How do you find your total daily energy consumption

[@JerryMartins-vh9vc]

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.??

[@michaelakomolafe9249]

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.

[@victoruzoma1083]

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

[@LameckLuyima]

Another question is let's assume the days of autonomy is more that one day

[@GeofreyKamudeuke]

Is the battery lithium / lead acid

[@StepDoku]

Can the Growatt SPF 5000 ES charge a 15kwh battery with a 4950 watt panel?

[@peterakoh3432]

Yes it can. It would take 3-4hrs depending on your DOD

[@StepDoku]

that is great to know. meaning i dont have to increase the solar arrray yet until i increase the inverter size...@@peterakoh3432

[@AharJohn]

Thank you sir for good teaching. Sir is there 24v battery of 200Ah?

[@michaelakomolafe9249]

You will connect 2 units of 200AH/12v battery in series to get 200AH/24v battery bank

[@iraboramiohu9585]

​@@michaelakomolafe9249why was 24 volts considered instead of 12volts on the nominal system voltage in the final calculation?

[@olujimikolawole6240]

You forget the day of autonomy and the battery temperature.
