How to make your own home solar. With Pictures + solar book

[arvin1171]

sir buti po nde nag ootomatik off ung APC mo? kc dba meron yan Smart off ata tawag nila dun, kc naka try ako ng ganyan dati, after 20 mins mag shut off sya, tapos need ko ulit i on then loop na un every 20 mins.

hindi ko nararanasan sa apc ko yung mag shut down, alam ko nag aautomatic shutdown ups pag mababa na voltage battery, yung apc model ko merong extension port connector ng battery external sa likod, ibig sabihin designed siya for additional external battery to increase capacity, nilagyan ko na lang siya ng dc fan para di mag overheat.View attachment 295186

paano po yung ratio ng solar panel sa battery for example kung 100AH yung battery ilang watts po yung solar panel na tamang ilagay

It depends if you use a controller or not. And if you use a PWM controller or a MPPT one!

Example for 100 Ah battery:

. No controller = 20 to 50 watt panel
. PWM controller = 120 to 200 watt panel
. MPPT controller = 100 to 150 watt panel

 

[TristanWS]

sir josepepe... karamihan sa mga solar installers ay 200W panel is to 100AH battery (PWM scc) ang niri-recommend... ang computation ay base sa assumption na 50% ang DoD at 5 hours lang ang Sun Hours sa Pilipinas... meaning, sa loob ng 5 hours ay kayang ibalik ng 200W panel ang na-discharge na kalahati ng 100AH... therefore, kung makulimlim maghapon maski ang 200W panel ay hindi mapu-full charge ang 100AH battery... kaya niri-recommend na meron ka din AC charger in case na sunod sunod ang makulimlim na panahon.

 

[josepepe]

Merry Christmas po sa lahat. thanks po s reply

 

[aldenlazo12]

salamat dito sir.

 

[josepepe]

happy new year

 

[awinahe]

Many thanks to all of you who participated in the life of this thread all these years... hope it will last for many years pa!

Wish you all a wonderful and sunny year 2017

 

[TristanWS]

... ganito pala itsura kapag ang solar panels ay linipad ng bagyo...

 

[SiRhOSEven]

Magkano po nagastos nyo ts?

 

[ahmish]

hi sir! happy new year.

ask ko lang po regarding sa battery bank.

meron po akong 120Amps na solar master. ask ko lang po kun pwede ako dumagdag ng 200AMps na solar master or dapat the same specs po sa 120Amps na solar din.

ask ko din kun may idea po kayo sa bagong deepcycle ng motolite yun amptech po

...first of all, ang capacity ng battery ay dapat AH (ampere hour)... at dapat same specs talaga (pati edad), meaning sabay dapat pagbili ng battery... si ma'am TS ay 3x120AH solar master ang battery bank (12V system)... umabot ng 5 years... samantalang ang 100AH solar master ko ay inabot lang ng 2 years and 11 months (positive grid corrosion ang sanhi ng pagkamatay or nangingitim ang kulay ng electrolyte).

wala akong idea sa motolite amptech.

WHAT ARE AMP HOURS (AH)
Source: http://all-about-lead-acid-batteries.capnfatz.com/all-about-lead-acid-batteries/lead-acid-battery-fundamentals/what-are-amp-hours/

Lead Acid Battery Amp Hours (AH) Specification Defined

The Amp Hour (AH) specification provides a measurement of battery capacity. In other words, it is an indication of how much energy can be stored by the battery. A typical Amp Hour specification might read, “100 AH @ 20HR”. The specification is saying that the battery will provide 5 amps of current at a useable voltage continuously for 20 hours. The “5 amps” was calculated by dividing 100 by 20.
Similarly, a battery with a specification that reads “150 AH @ 15 hours” will provide 10 amps of current at a useable voltage continuously for 15 hours. It should be noted that a useable voltage is considered to about 10.5 volts and above on a battery that is under load (or has devices connected).

IMPORTANT! Having defined the AH specification, it is important to understand what the Battery Specification does not say.

A Common Misunderstanding Associated with Amp Hours

Consider the 100 AH battery. As indicated above, it will provide 5 amps of current for twenty hours while maintaining a voltage above 10.5 volts. A common mistake is made when it is assumed that the 100 AH battery will also provide 100 amps for 1 Hour. It won’t. In fact, a battery of this type may only provide about 40 minutes of continuous 100 amp service at best. This is due to a well-known characteristic associated with lead acid batteries. Specifically the capacity will decrease as the rate of discharge increases. In other words the relationship between battery capacity (how much energy is available) and the rate of discharge is not a linear one. The phenomenon being described here is known as Peukert’s law

Other Amp Hour Rates

As indicated above, the Amp Hour specification on 12 volt batteries is normally based a twenty hour rate. In fact, the specification is so standardized that battery labels often do not include this information. That said, it is important to be aware that deviations from this norm are not uncommon. Some battery manufacturers will establish different rates for their amp hour specification. For example five and ten amp hour rates are not uncommon. In the case of a battery manufacturer who specifies a 100 AH based on five hour rate, the claim is that the battery will provide 20 amps for five hours before dropping below 10. 5 volts.

As previously mentioned, the AH hours is gauge that is useful for relative comparisons. When comparing one battery to another for example, the Amp Hour specification will tell us that a 120 amp hour battery will have more capacity than an 80 amp hour battery.

TS,
Happy New Year sa Lahat!
Pa Advise po..
1. Ano po ang trending ng price regarding solar components and its accessories..nagbago po ba ang pricing?
2. I have a low budget because of other (higher) priorities, is it advisable to start on buying cheaper components for start-up. (1-250WMono SP, 2-10Ah Batt, 1000WPureSW Inverter,1-MPPT Controller)
3. Dba po palagi ang sagot sa tanong na When is the right time to buy or start? Now is The Right Time.. I will consider po ur answer s tanong ko po sa number 1..
Salamat po TS.. Sana d po kayo naguluhan sa mga tanong ko...

lahat ng solar parts and components ay imported, therefore tataas ang presyo dahil sa exchange rate ng peso versus dollar... ako kasi, bumibili kung kailangan ko... kung stable at reliable naman ang kuryente diyan sa inyo, wala kang need na mag-solar... unless gusto mong mag-aral about solar power (katulad ko).

Sir Tristan, ano po senyales na sira na po battery,

meron kasi akong 120AH solar master pero pag mainit sya umaabot sya ng 13v. pero pag ginamit mo po kahit 100% full ang battery bigla syang nag 12v. at 11 volts po.

 

[ramjekhan76]

Good Morning Sir,

Pwede po pa bookmark? magandang thread ito matagal ko na gusto matuto ng solar, maraming salamat sir..

God Bless.

anim ang butas (cells) ng battery... bawat cell kapag full charge ay more than 2.1V (kaya 12.7V dapat kapag sinukat mo ng digital multimeter after resting for 6 hours).

kapag mabilis na siya ma-full charge pero mabilis din bumagsak sa 10.7V maski walang load, senyales na yan na sira na ang isa or dalawang cells.

dapat habang tsina-charge si solar master, hindi umi-init ang casing ng battery... kapag umiinit, senyales na iyan na mataas na ang internal resistance ng battery (sira na).

kapag umabot ng 3 years na gamit ang solar master, sulit or hindi ka na lugi diyan.

madali lang sya sir mag undervolt pag gumagamit ng load. pag normal naman na walang load nasa 12v sya pag hindi puno.

 

[TristanWS]

madali lang sya sir mag undervolt pag gumagamit ng load. pag normal naman na walang load nasa 12v sya pag hindi puno.

kapag hindi pa bumagsak sa 10.7V (after resting for 6 hours), hindi pa sya sira... posible na sulfated lang siya kaya bumaba ang capacity (madali na ma-low batt).... ang gawin mo ay "charging without load"... meaning, huwag mo muna gamitin ang battery... i-charge mo lang siya hanggang umabot sa 14.8-15V... hayaan mo sa 15V ng mga two hours... ang tawag diyan ay desulfation/equalization.... si sir ronel ay umabot ng more than 1 week "charging without load" bago bumalik sa dati ang capacity ng battery niya.

ay ganun pala yun. binili ko to last august. pwede pa kaya dagdagan ng isang battery pa? or too late na?

binili ko kasi sya last august. then bumagyo ng september kaya since september until december po hindi nagamit yun battery.
