Hi, Jeff. The output in this case comes out of the charge controller. Since the loads are DC and the input is DC (battery), then this system works for DC bulbs and DC fans. It won't work for 3phase pumps or appliances that run on AC power. In such case you would need an inverter.

@@geinstein337 ,Just for understanding:What would happen if I only add 50%of 20 ah to 20 ah to compensate for the depth of discharge, making 30 ah and multiply this by 2 to compensate for the no- sun- day, that is 60 ah as the capacity of my battery(bank).I also use the data in this video in this calculator www.altestore.com/store/calculators/off_grid_calculator/ and found out that one day of no sun is 2 days there, and 104 watts of solar panel.did you tried that calculator?What is your point of view on the 104 watt just mentionned?Thanks for your answer.

Thanks.

Well explain sir. Hope soon u can discuss also about protecting device between solar and meralco short circuits. protection.

I like to recommend that there is an error in determining the amperage rating of the charge controller. Note you have a battery size including autonomy and DOD at 50 % is 80 Ah, which you estimated as 100Ah. In determining the size of the array or modules needed, accounting for 3 hours of sunshine in such a locality and battery voltage of 12 voltage : (100Ah x 12 voltage) / 3 hours = 400 VA (Watts). For Charge controller, since battery voltage is 12 voltage, we have : 400 VA / 12 Voltage = 33.3 A. This could be rated up as 40 amperage charge controller.

For 100Ah battery though, a 200W solar panel will do. 200W = 200VA. 200VA/12V = ~16.6A, which would require a 20A charge controller.

Some confusing in this Video. You didn't unclude Autonomy AmpereHour for sizing Charger Controller. (100Ah/3h = 33.3A or 40A atleast ratings of Charge Controller). You miss also number of Panels based from Autonomy usage (33.3A/6.7A = 4.9 or 5 Panels). And how did you compute to get Peak Power Current 8A of Charge Controller?

You don't need that big a current. Firstly, only 50% needs to be charged and discharged. More than that and you destroy the battery. Secondly, the 100W panel cannot output that much current. Check its Max Power current and and it won't even be higher than 5A.

padali in mo nalang boss. ganito lang po yan kuha ka ng battery tapos tingnan ilang volts kadalasan 12v tapos ilang Ah ang battery like 48Ah normal na battery ng sasakyan... so 12v X 48Ah = 576W so kong meron kang 150W na panel maka produce yan ng 600W sa loob ng limang oras. pano?. ganito yan sa 150 W na panel meron yang power loss 20% so 120W nalang multiply buy 5hours = 600W kada limang oras. yan yung mga oras na tirik ang araw... ma full charge ang battery mo apat or limang oras kung gusto mo mapadali dagdagan mo panel mo like x2 para dalawang oras lang. so kung gusto mo ng fullcharge palagi ang battery na parang di nababawasan mag lagay ka ng apat or 4 na panel na tag 150W para sa battery na 12V 48Ah. yan yun.

Thank you for your nice and clear explanation. Please just check for me I have calculate the solar system for load profile of 750W and we have sun of 7 to 8 hours .and no autonomy days. Load is 750W for 16 hours 750Wx16 hrs = 12000Wh =12000VAh 12000VAh/24V= 500Ah We need 500Ahx2 = 1000Ah 50% discharge for lead acid batteries.no days of autonomy. Number of batteries = 1000Ah/180Ah=5.5 =6 batteries of 180 Ah Solar panels 500Ah/7hours =71A 12000Wh/7hrs=2714watts Panel specs 700W, 17.69Amax No of panels=71A/17.69A=4.2 is 5 panels . 80A , 24 V charge controller needed. I will appreciate your help . Thank you 🙏 Sir.

No inverter? My well pump runs only when I use water, but without power I have no water. This is a 3 phase motor. So I need panels, cables to connect to charge controller, batteries, circuit breakers/fuses, and some way to manually switch from the grid to my storage if power goes off. The numbers and math concerning these components is all Greek to me. What size controller, inverter, gauge wire, etc should I buy? No inverter? Where does the power come out?

Thank you sir .. in Saudi there is more than 7hr of sun my loads are 800Watts and i'm using 12V battery what are the Amps coming out of each panels so i can buy a bigger Charge Controller form AMPS coming out of PV

for ac load ... you will use inverter that convert from dc to ac .. that's will be placed between the charger controller and the ac load ...

If 80Ah or 90Ah is available in the market then use it to give 1 day autonomy time.

What should be the wire size to be used if I were to extend my wire 39 meters from the charge controller? should I also consider the voltage drop in a system like this?

I dont know if you are still following the topic, however I have a question. You have calculated the charging current based on the 20Ah battery, but you have also made the decision fo using a 100 Ah battery, then why use the 20Ah figure. By using this figure of 6.7A we will never charge the 100Ah battery in a whole day (suntime) of 3 hrs Can you please correct me , wher I am wrong

@SteffanyaArtsTV

for 100Ah battery you need 1200W panels

Size of wires sir

Just for 4 lights. This is really outrageous. You need to set that panel at a sun trackable angle. Also most people do not keep all lights on for 12hrs. So to power a fridge or Air conditioner you will need 100panels from your calculation😀😀😀 This what you get when you can't tell the difference with 12v and 24v panels and photovoltaic or monchristalin panels.

Pag on grid sir..pano..para wala na battery

I don't understand why you need a 250W panel here. What we need was 7amps. If we take the MPPT voltage at 18V, then the required panel is 126W panel. So in that case even a 150 above is good and no need for anything more than 200W for PWM charge controller. I am considering the system voltage as 12V. Sir please clarify how the panel was calculated.

pag madaming appliances calculate mo ilang Wattage . lahat lahat na gagamitan ng solar kunin mo yung wattage W= (A) V so if 1200 watts yung total kailangan mo ng 100Ah to 110Ah full cycle battery 12V so do the math 12x100=1200W so kailangan mo ng 1600w na panel para ma cover yung 20% power loss 1600 less 20% is 1280W mga 16pcs na 100W na panel yan kong may malaki e di mas maganda mga 1800W yung power inverter wag masyado malaki lalaki ang power loss.

That's the job of the charge controller. But think about it also. If the battery is full and there is lots of solar energy, where will that energy go? It will go to power your DC loads. If the battery is half full and there is still lots of solar energy, some of that can go to charge the battery and some of it can go to power the loads.

Massively oversize and the start is wrong. first of all cut the inverter cost and effeciency out by ding DC lighting. Do a bit of research and determine the exact lux levels . see if you not can use back reflextion to double up on the just two.. choose two smaller batteries rather a bigger battery (replacement can be scheduled. with the inverter losses gone, it overwrites the massive derating you have done on the panels. To be honest, this is completely wrong.. each light should have been treated with it's own little small battery dc led...
