Sa ngayon eh ang gusto ko lang po eh meron ako emergency power to run my laptop and wimax modem. Is this a good deal?

or

Invest nalang ako sa conventional setup for future if ever mag solar ako sa bahay?

-Laptop
-Dc Fan
-2 to 3 Led bulb
-Wimax modem

Eto lang yun plan ko iload sa solar if ever.

Ano po maganda setup to run:

1. laptop and modem (full solar - day and night 24/7).

2. laptop, fan, modem (solar during the day and AC wall at night).

Thanks in advance.

You are the only one who can answer this question... both are possible of course but it depends on your budget... are you thinking of grid tie for the solution 2?

@kizsdet

... how much yung Yeti 150... tiningnan ko ang battery ay agm 12v 14ah lang... masyado maliit... hindi kaya yung balak mo na load.
"-Laptop-Dc Fan-2 to 3 Led bulb-Wimax modem"
halos ganyan ang load ko ngayon... kaya naman ng 160w panel>100AH battery>20A pwm cc >350w pure sine wave inverter... pero hindi 24/7 ang network ko... about 8 hrs lang a day... ang led 12v bulbs ay every night at ang dc fan ay tuwing brownout lang.

yung kay sir bongalzate ay 3x100Ah ang battery >20A mppt cc >1000w inverter >forgot the watts of panel... 24/7 ang network nya.

I'm not sure about grid tie. Bago lang po ko nag rresearch about solar, not so familiar with the terms. Nag bbackread pa po.
Mga magkano po kaya budget to run those appliances given those two scenarios?

14k sir. Pro after backreading eh nagbago na isip ko. Madami na ko mabibili sa 14k, hehe.
Ahm, kano po nagastos nyo sa setup nyo?
Kaya na kaya sa 200Ah i-run ang modem and dc-fan for 12 to 14 hrs every night?

... ang pinaka-expensive ay ang battery... yung 200AH solar master ay 12K na... mas mura ang grid tied system kasi wala nang battery... ang pinaka-murang panels at controllers ay sa raon at cdr king... sa pure sine wave inverters naman ay sa olx... try to canvass first then post here for the comments of users.

salamat po sir/ma'am for the info

@busar

3pcs x 120ah batteries + 1 unit 1,000w pure sine wave inverter ang gamit ko sa 1st solar project ko. I have 4 solar projects sa bahay.

Soon bibili ako 2,000w pure sine wave inverter kay brightpoint pag bumigay na yung used batteries ng second solar project ko.
1,000 watts yung laser printer/copier namin sa office....di kaya ng 1,000 watts inverter kasi nakakabit din sa computer pag brownout.

Di ko magagamit max 1,000 ang inverter dahil may percentage of efficiency yung manufacturer.
Example efficiency is 89% so 1,000 x 89% = 890watts lang ang max watts mo.
Pero kung ako tatanungin mo, baka 750w and below ko lang gagamit ang inverter.

May self-imposed margin of safety kasi ako sa mga solar projects ko.

sir busar...

si ma'am TS at sir bongalzate ay tatlo ang batteries parallel connected (refer to 1st page to see ma'am TS setup)... both are using 1000watts pure sine wave inverters... nakalimutan ko na kung 1000 watts din ang inverter ni sir bongbenitez... sana sila ang mag-reply sa tanong mo kasi sila ang may actual experience sa pag-gamit ng 1000 watts inverter... kung ilang watts ang maxiumum loads nila.

... yung nagbi-beep na TBE inverter mo ba ay nasira na?... wala na bang output?

@hjbg30

Dami ako binasa bago ang ako mag start mag solar project.
May mga tinanungan din ako regarding set-up na mga technically inclined.
Nang mag start ako on my own.....gumana yung solar project but below expectations......mabilis naubos battery power....mahina ang 12v lights....
Hindi ko na maximize yung components ng solar project at walang safety features ang solar project..

So I decided to contact a solar installer.
Iba pa rin pag may tutulong sa iyo pag gawa.
May nag guide sa iyo....at marami ka matutunan sa kanya.

Sa budget mo na 45k marami ka na magawa but make sure may safety features and solar project mo.
Buy quality and highest amps mppt inverter dahil yan ang mag dedecide kung ano maximum panel and load ang magagamit mo.
But mayron ka rin masisira na gamit (busted fan, busted 12v light bulbs, etc. ) due to experimenting....charge to experience.

If you need the solar installer, PM me.
Kayo na mag usap dahil baka his rates depends on location.

Lumampas na sa P120,000 nagagastos ko sa off-grid solar projects namin, inclusive of solar installer payments.
Office Computers can run even during brownout.......
Office fan of 12v to help the aircon....
Lahat ng rooms sa bahay may solar lights with individual on/off switches.
May perimeter solar led lights sa compound namin na nag-on/off automatically.
24/7 na solar powered internet and soon 24/7 solar powered na CCTV.

Mga 2,500 a month na ata na bawas sa Meralco bill namin per month.
Di pa malaki maibaba na savings dahil may office air-con kami naka on 8 hours a day.

Next year mag on-grid na kami to power the aircon, ref, plantsa, etc.
Start siguro sa 1kw.

Mahirap talaga maging solar addict.
Magastos but fulfilling...... lalu na kung ang bahay ninyo sa street ninyo lang ang may ilaw, fan, radio at TV pag may brownout.

... yes, thats right, and the proper size of the inverter is 200AH /10x12=240watts.... ang ginawa ni sir bongbenitez ay nag-hire ng isang solar installer available sa location nya, tapos bumili sya ng parts and components sa different sellers depending on price and availability... syempre binayaran ang solar installer pero mas mabilis at safer natapos ang setup nya... at natuto sya at the same time.

btw, computation is based on batterystuff.com solar calculator... zero backup day.

@kizsdet

Kung gusto mo pang emergency lang, bilhin mo na yang goal zero but compute load usage Watthours versus watthous of 14ah battery.
Maliit lang yang 14ah battery. Yung 10ah battery ko nga kaya yang 9watts and 3watts na 12v led bulbs but mga 7 hours lang siguro.
Lagyan mo pa ng laptop at wifi, gapang na iyan.....

But if gusto mo may room for expansion......bili ka na lang ng components then make a solar project.

Sharing my build...
kaka-addict. Na mount ko sa board gusto ko na i-wire lahat kaagad. hehe

http://img.photobucket.com/albums/v356/glennjv/ManualHybridv1.jpg

wala pa yung Off Grid components. Literally CC, Inverter and Battery nalang kulang sa materials

 

[hjbg30]

@bongbenitez sa gen trias cavite ako gusto ko sana na magdamag na ilaw sa gabi kahit 2 or 3 tapos paminsan minsan na gamit na ilaw 3-4 sa loob, 3-4 dc fan, 1 desktop pc with modem (baka ito optional kasi magdamag ang gamit ko lagpas sa 12hours)at 32" led tv yun lang ang appliances na pedeng paganahin sa bahay namin. Aircon namin 3/4hp pero optional for future na lang sya. Sana di umabot or bumaba lang sa 45k lang ang gagastosin. sa ngayon naghahanap lang muna ng info at kung ok ay mapaghandaan ang gagastusin

... hehe, na-realize na yata ni sir glennjv ang disadvantage ng battery system... nagda-dalawang isip na... pero kami na nasa probinsya ay walang choice dahil sa unreliable ang mga electric coops.

.. sa gen trias cavite ako... Sana di umabot or bumaba lang sa 45k lang ang gagastosin. sa ngayon naghahanap lang muna ng info at kung ok ay mapaghandaan ang gagastusin

... sa gen trias cavite si "olx jayrene"... doon ko nabili ang 12v dc fan at 350w pure sine wave inverter... recommended din dito si "olx brightpower"... pero canvass ka muna sa raon (if you have time) to have an idea of the prices.

... marami ako nababasa na mahirap daw mag-import ng solar parts and components ngayon... mahirap daw specifically sa customs.

 

[poseidon]

Sir Tristan wala na sa ads ni maam jayrene ang 350w psw inverter.. magkano mo nakuha sa kanya ang psw?

 

[TristanWS]

Sir Tristan wala na sa ads ni maam jayrene ang 350w psw inverter.. magkano mo nakuha sa kanya ang psw?

... 4.5K ang bili ko noong june 2014 (93% kasi efficiency)... as i said, pahirapan daw ngayon sa customs kaya marami wala stocks... tingnan mo kay "olx brightpower", marami new arrivals... mas mura pero mababa ang efficiency.

 

[spo0ns]

medyo malaki-laki ang gastos.. pag iipunan ko muna..swak to sa bukid namin na wala pang kuryente..salamat dito boss...

.. bantayan mo na sa cdr king ang solar panels kasi palaging out of stock yan... kung gagamit ka ng 12v battery, ang bibilhin mo ay yung panel na 18v Vmp.

 

[bongbenitez]

Nag try kami kabit yung 24/7 CCTV na kabit sa 12v solar power.
Using a wattmeter, 60watts ang max consumption reading.
Tutal puro 12v 1A ang adapter ng cameras at 12v 3.3A ang DVR.
Nang makabit na namin ang DVR and 2 cameras, may distortion sa display.
Di na namin kinabit ang additional 2 cameras.
Mukhang di puwede 12v solar power. May interference sa screen.
Kahit na may magnet sa 12v power supply, ganoon pa rin.

We will rewire from the 1,000w inverter and connect to the CCTV para 220v na lang ang power.
Nag try kami using a looooooong extension wire, gumana naman ang CCTV.
But for extra margin of power, mukhang I need to buy another 120ah battery dahil 24/7 ang use ng CCTV.
Add another solar panel to the existing 300w.

We need the extra power also to connect if possible the LCD Monitors to 220v solar.
Di puwede 12v direct kasi iba-iba ang voltages ng LCD Monitors...may 14v...may 19v...may 12v....may 220v (mga sinauna na LCD)

@TristanWS

Sir TristanWS,

Minsan sa mga cdrking stores, pag display item na lang available na solar panels, ayaw na ibenta.
Display daw ito. Magugulo ang display items nila.
Ewan ko kung ano logic doon. Pera na, ayaw pa nila.

.. bantayan mo na sa cdr king ang solar panels kasi palaging out of stock yan... kung gagamit ka ng 12v battery, ang bibilhin mo ay yung panel na 18v Vmp.

 

[poseidon]

Ang laki ng itinaas ng presyo ng solar panel ni daking. Almost 20%. Ang dating Php2280.00 naging 2,480.00 na ngayon. Pansin ko rin dumadami na ang naghahanap ng solar panel. Palagi na out of stock ang branch na malapit sa amin.

 

[hjbg30]

"olx jayrene" website nila ay solarenergyph nag train at nagbebenta rin sila medyo alam ko yung location. nung nagtatanong ako sa kanila for training gusto nila tawagan sila nung nag ask. pero sa ibang nagtanong email lang ok na nung nag ask ako ng email na lang for more info wala di na sumagot

Question:

can you connect Loads like 12V LED, 12V Fans, etc while the battery is charging?
Since the Charging voltage from the panels/scc is much higher, would i need to regulate it somehow? (DC - DC Buck Converters?)

*this might have been asked before.

 

[bongbenitez]

@glennjv

Yes, if you have a solar controller.
I don't have an answer if you are not using a solar controller.

We have an office in our house.
During daytime, office lights are loads of the battery even if the battery is charging. The 12v office fan is on even if the battery is charging.

Just make sure the charging amps you get from the sun is more than the load amps used during the day.
Otherwise, there will be deficit amps (you used more load amps than the charging amps).
If that happens, you won't get the battery fully charged and have little use during the night.

Our Solar controller has an optional LCD monitor that tells me the battery and load amps.

If its a cloudy day and load amps is higher than battery amps, we turn off the 12v fan and use only the solar lights so that the batteries can be fully charged.
If its a sunny day and load amps is lower than battery amps, we use both the solar lights and 12v fan.

The Solar controller will regulate the load voltage.
Attaching a DC breaker will also help regulate the voltage/amps to avoid surge/spike/wire burnout.

Yes you can! As said Bongbenitez, no problem if you have a controller... if you don't use a controller you can use a dc-dc adaptor like the ones used by sir Bongalzate or the one sold in cdrking
I usually turn my lights on at night but I happened to turn them on while battery still charging and did not get any problem (no converter, direct to battery)

@bongbenitz and @awinahe

salamat salamat sa reply.
I was thinking the fans and leds might tolerate the higher voltage pero i'm not sure.

Now i'm thinking how about other electronics, like cellphone car chargers or other sensitive electronics.

my friend is the one that's actually going for a direct 12V setup.
Ang una nga niyang bibilin is the 12V 100AH battery as backup for brownouts. Our Airsoft Turnigy Multicharger can re-charge naman Lead Acid batteries.
Then He'll get a Panel and SCC. Unusual route pero effective.
I told him he doesn't need a inverter and go with 12V appliances, i knew you guys are using 12V appliances and i see the benefit.
He already has a existing small 150W CDR king inverter for small 220 loads like their LED TV.

may mga nakikita kaming DC-DC Buck Converters for ranges from 300-700php sa olx.ph and amazon.com.

Ang problema di ko alam how these Buck Converters behave.
Input Voltage i see are flexible where it can accept anything from 5V-30V.
Output from 5V to 24V as well.

Ang tanong ko... if for example you're input is at 14-15V kasi nag cha-charge and then i adjust the output to 12V.
Papano if hindi na nag-chacharge, so the input drops close to 12V as well, how will the buck converter react? will it also drop below 12V to compensate since the input voltage has dropped?

Is it a fixed voltage drop or it regulates and tries to maintain 12V?
