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

okok, ayoko namang bumili ng sine wave para lang sa led bulbs, hindi pa ko nakakabili ng kahit ano inaaral ko muna. mukang fans lang talaga magagamit ko.

EDIT: pero pwede rin, kung 12v panels gagamitin ok lang kung 12v dc led bulbs pero di na dadaan sa inverter??

EDIT uli: pwede ba to??

led strip light ung sa ilalim ng motor at kotse nakalagay 12 v dc current pag kumuha ako ng white maliwanag kaya?? pero kung madaling makakita ng dc 12v led bulbs un nalang

bali ganito lang ung diagram? ibig sabihin hindi na dagdag load sa inverter ung led bulbs kasi direct na sa battery?? pero parang gusto ko mag controller para safe lang di pa ko sure sa panel

sir 2dennis2.. dalawang klase ang panel, yung pang-offgrid (12V battery panel) at yung pang grid-tied (high voltage panel).. madali na hanapin ngayon ang led light bulb na 12V at fans na 12V din.. no need to use inverter kasi may power consumption pa ang inverter maski walang nakakabit na load.. i agree na pag-aralan muna bago bumili.
 
12 v panel lang po, tapos ung fan namin madami un magastos palitan mga 6, or pwede ko ba gamitin un sa 12v dc??
 
sir 2dennis2.. kung meron ka na AC fans, inverter talaga ang kailangan mo.. tapos kung gagamit ka ng charge controller, dapat pag-aralan mo rin pag-partner nito sa panel base sa kaya nitong padaanin na amperes.. halimbawa 10A, 20A, 30A etc.

sir tristan...kng series panels sir...tataas voltage...baba naman amperes

I'm very sorry but like Sir Tristan, I don't know a lot about Grid Tie :(
I think that with a 300 watt gti you need at least 400 watts of panels. Did you check the out put voltage of your panels? The wiring?

yes mam awinahe all checked...baka ma over worked mam ang gti..advise kasi nila wag isagad ang watts ng panel sa watts ng gti...tnx po sa inyo ni sir tristan...God bless

First of all: you are planning a big setup if you just want to power 1 fan and lights, 300 Ah of batteries is a lot of expenses for a small impact on your electricity bill... how many watts is your fan? how many lights and how many watts your lights? How many hours do you plan to use them (fan and bulbs)
As said Sir Tristan 12 volts bulbs are better as you just plug them directly to the batteries... no need inverter. A 12 volt fan is ok also but you need a good quality one as the cheap ones have the tendency to melt or be sira after few months. If you buy lights and fan all in 12 volts you don't need inverter.
The lights strip from cdr king are like christmas light lang, I don't think it's for everyday lightning! But if you want to use them as decoration, as they are in 12 volts, you can plug also directly to the battery (no need of the adapter)

405watts worth of fans po balak ko mga 6 pcs un, then inverter ko nalang, 100 ah battery lang din balak ko kung 60 kasi baka kulang, ung iniisip ko nalang kung gano kataas na amp ng controller ung mejo abang na for upgrade ng panels, wiring pa pala aaralin ko, cheap inverter muna kasi papalitan din un
 
base sa more than 5 years experience.. ang small solar off-grid set-up ay OK lang na pang backup, halimbawa kung may power interruption dahil sa bagyo.. pero masusulit ang gastos mo kung umabot ng 4 years ang set-up.. ang unang bumibigay ay ang battery.. para sa akin naman, ang pinakamahalaga ay yung mga natutunan ko sa pag-generate ng kuryente using solar.. sa knowledge pa lang ay sulit na sulit na.

hindi sigurado na makakatipid ka agad-agad, kasi kung nasira agad ang battery, bibili ka ulit maski hindi mo pa nababawi ang pinambili mo ng nasirang battery.. pero kung umabot ng 4 years na walang nasisira, siguradong nabawi mo ang nagastos mo.

Sorry I did not read properly! I thought you have only 1 fan...
405 watts of fans with a 100 Ah battery? If you want to run them all toghether your battery will last 1 hr lang! (considering that you should not discharge more than 50% your battery)
 
450watts x 24hours=10800watt/hr ;10800*3=32400; 32400*2=64800 watts
64800/12=5400 total Ah

napulot ko lang sa ibang site cannot be gawin haha,

baka gawin ko nalang ay pure dc set up parang mas matipid un
siguro 2 fans lang for 12 hours then mga 4 pcs 3 to 5 watt led bulbs.

nakita ko kasi sa cdr king site dc fan na 23w 18'' , ganun din kaya computation nun sa ac?? kasi ung fans namin may 65 at 115 watts na ang layo sa dc fan.

parang mas ok kung gumawa nalang ng dc outlets mas matipid wag na mag inverter
 
base sa personal experience, kapag 12V DC system, mas efficient na 12V DC led light bulbs at 12V DC fans ang gagamitin.. mas matagal ma discharge ang battery.. kung iku-kumpara sa gagamit ng inverter.
 
hmm.. 12V Dc refrigerator with built-in timer.. pwede.. 333 us dollars.. medyo mahal.. makakatipid kaya or maganda lang pang backup?
 
May different types po ba ng controller for different types of battery??


Ung ref d talaga pwede ng mga pang kotse lang pwede
 
base sa personal experience, ang lithium ion battery ay kailangan ng BMS (battery management system).. ang lead acid battery, kung solar, ay kailangan ng solar charge controller (PWM or MPPT).. kung AC charger naman.. manual charger or Automatic charger.. ang mga charger ay rated sa Amperage, example 10A, 20A. 30A etc.
 
meron sa lazada, cdr king at mga specialty stores or solar sellers.. mas ok kung may physical store para may after sales support.
 
meron naman pero baka mag cdrking ako ung basic setup lang at mura maghahanap pa ko ng battery capacity at voltage indicator
 
Mga master, paturo naman safe way to clean battery terminal at yung wire nagkaroon ng corrosion. Ano po mga safety measures takot kasi baka makuryente ako wala po ako masyado alam sa ganito. Sabi yung negative muna alisin ko bago linisin yung positive terminal. TIA po sa papansin.

i-OFF muna ang load kung nakakabit pa, para hindi mag-spark.. negative muna ang tinatanggal ko..yung white substance na nakapaligid sa terminal ay lead sulfate, yung bluish substance, copper sulfate ang tawag.. may binibili sa handware na battery brush.. pang-alis ng rust, lead sulfate at copper sulfate.. tapos tunawin ang baking soda sa malinis na tubig.. isawsaw ang basahan dito at ito ang ipunas sa mga terminals at post... mag-safety glasses ka kasi delikado sa mata.
