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

[TristanWS]

sir raypaz.. wala ako experience sa gti, kaya wala ako advise.. ano ba ang epekto kung series ang panels mo?

 

[awinahe]

gd pm mam awinahe..sir tristan...hingi sana advise...gti ko 300watts bosca 10.5 to 30vdc...panels ko 300watts in parallel...Glowmax ...pede ko ba gawing 400watts pv ko..facing 165deg south..10deg angle...maximum harvest sa transit ng araw only 150watts...using omni wattmeter...savings ko 100plus pesos lang...me dapat pa ba kong i modify?...salamat

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?

ganyan din sa akin sun g gridtie 300watts socen panel 100wx3 parallel harvest 170w max harvest pero na try ko 2 battery series 2sm 24v harvest nya 224 watt ngayon gamit ko 1kw sun g gtil at 4x 285w solar phil. panel max. harvest ko 850w palang nakita ko dahil kakabit ko pa .


check mo rin ung voc ng panel mo di dapat lalagpas sa 30v masisira gti mo .

mga master ano bang kailangan sa 50w solar panel ko ilang ah ng battery kailangan ko salamat

 

[TristanWS]

mga master ano bang kailangan sa 50w solar panel ko ilang ah ng battery kailangan ko salamat

Charging time of battery = Battery Ah / Charging Current
.. ang 50W panel ay kayang mag-produce ng 3.3A (cdr king panel).. therefore 100Ah / 3.3A = 30 hours charging, kung 50Ah = 15 hrs, kung 25Ah = 7.6 hours, kung 12Ah = 3.6 hrs.. sana ay ma-gets mo.

 

[russh168]

salamat sir wala po akong idea saganyan gusto kung makatipid din sa kuryente lalo na ngayon abot ng summer laging gamit mga fan . pero intresado ako matuto kaya more basa pa at youtube muna salamat sa reply sir.

 

[TristanWS]

sir russh168.. sana ay napansin mo na depende sa charging amperes, pwede ka gumamit ng maliit or malaking Ah na battery.. kung malaki ang Ah ng battery matagal din sya ma-charge.

 

[aron41]

sir russh168 yan po state of charge ng battery sana makatulong din yan View attachment 341545

 

[russh168]

TristanWS at aron41 salamat po sa reply marami na ako natutunan d2 para makabou ng minioffgrid solar

 

[TristanWS]

sir russh168 btw, balak mo ba gumamit ng solar charge controller sa 50W solar panel mo? or hindi na (katulad ni ma'am awinahe)?

 

[2dennis2]

mga master may nakidlatan na ba sa inyo?? saka nung nag set up kayo same wiring sa meralco or bagong wiring? sensya na baka pang noob tlga tanong ko

 

[TristanWS]

sir 2dennis2.. 12 volts na de-baterya ang sa akin.. same lang ng wiring ng kotse.. kapag inverter naman ang gamit, hiwalay din ang wiring sa meralco.

 

[awinahe]

mga master ano bang kailangan sa 50w solar panel ko ilang ah ng battery kailangan ko salamat

Without controller you can charge 100 or 120 Ah battery without problem in a normal sunny day... but of course it depends if you use it while charging or not and if your battery is 20 or 50 or 80 % charged/discharged...

mga master may nakidlatan na ba sa inyo?? saka nung nag set up kayo same wiring sa meralco or bagong wiring? sensya na baka pang noob tlga tanong ko

Always ground your solar panel with copper wire to avoid any damage from kidlat!! regarding the wiring a regular "meralco" wire #12 is ok for panel to battery. A bigger one is recommended for the inverter to the battery and between batteries if you have several connected together (I, personally, use a big welding wire)

 

[2dennis2]

thanks sa mga sagot, baka may marecommend kayo na pure sine wave 300w inverter na brand saka price. sa cdr king lang ako tumingin parang puro modified.

 

[TristanWS]

sir 2dennis2.. sa OLX ko nabili ang sa akin, noong active pa sya.. sa ngayon sa lazada na ako bumibili kasi pwede ang cash upon delivery.. afaik, ang puresinewave sa cdrking ay 1kw, ang pinakamaliit.. dalawa na ang nabili ko, yung isa umabot lang ng 3 years, pero ang isa ay buhay pa rin up to now.

 

[2dennis2]

thanks sir, inisip ko tuloy walang baka walang ganun.

EDITung modified nalang gamitin ko kaya mejo mura e

 

[TristanWS]

meron sa lazada, galing sa china.. kaya more than 10 days bago ma-deliver.. more than 3K ang price.. pag pure sine wave ang ginamit, mas matagal ma-discharge ang battery kasi konti lang ang losses.. (hindi masyado umi-init ang pure sine wave inverter).

In general, because the total harmonic distortion is higher in modified square wave inverters, motors will run hotter (less efficiently, consuming up to 30% more energy than with pure sine wave inverters), and likely not last as long. Additionally, a modified square wave inverter will often cause a “buzz” to be heard from audio devices and sometimes other appliances like ceiling fans and microwave ovens.

ito daw ang mg hindi pwede sa modified sine wave:
• Laser printers, photocopiers, and anything with an electrical component called a thyristor
• Anything with a silicon-controlled rectifier (SCR), like those used in some washing machine controls
• A few laptop computers
• Some fluorescent lights with electronic ballasts
• Some battery chargers for cordless tools
• Some new furnaces and pellet heaters with microprocessor controls
• Digital clocks with radios
• Appliances having speed/microprocessor controls (like some sewing machines)
• X-10 home automation systems
• Medical equipment such as oxygen concentrators

It depends on what you want to power. But nowaday the modified wave inverters are better than before!
1 years and 1/2 ago, I bought a cheap 300 watt Osoni inverter/charger for only 1100 pesos... I did not expect it to last! But up to now, it works fine everyday powering a 15 watt ceiling fan, my laptop and led tv... I found it in a "chinese" store here in Puerto Princesa. Since one year and half I use it everyday saving me many amperes as it uses very few amps; and don't use anymore my big 1000 PowerStar which draws a lot of amperes from my batteries!!

 

[2dennis2]

405w na fan palang, balak ko ilagay fans lang at mga led light the rest meralco na,

pwede na kaya to? 150w panel, no controller( kuntador nalang para ma off ko) 500w modified sine inverter, 300ah battery,

stick lang ako sa simple set up ung kaya ng budget, basta plano ko 2:1 ratio lagi panel at battery

pwede na kaya to? balak ko mga june or july simulan

 

[TristanWS]

sir 2dennis2.. own experience ko, madali mapundi ang AC led light bulbs kung naka-connect sa modified sine wave inverter.. mas tumatagal ang 12V DC led light bulbs direkta sa battery (pareho lang ang liwanag).. ang panel mo ba ay 3x50W 12V panel? or kung isang 150W panel, ano ang voltage?
