Re: How to make your own home solar. With Pictures + solar b

Only solar power energy users know the feeling ma'am! lalo na pag matagal ang brown out, kulang na lang manalangin ako ng brown out ng ma-appreciate nila itong solar power ko, thank you po ma'am.

@ quark

Try a small solar project muna:
http://www.olx.ph/index.php/view+cl...+Ranking,Position,2-5,25#advertisementDetails

P300 lang. I bought that from another seller at P350. Ok naman sa usage. No problem din pag later on sira na battery.
Nakakabili naman ng replacement.

hmmm. masyado ata mahal ang price niya sir. may nakita ako sa fb group. ang price lang is P300.


pero pag may ipon na ako eh i will try iyong starter kit ng cdrking para may magamit in case ng blackout.


medyo busy ngaun kaya mabagal ang pacing ng pagbabasa. 63/173 pa lang.

Re: How to make your own home solar. With Pictures + solar b

After doing some reading regarding the importance of “Inverter size versus Battery size” and “tare loss” aka “No Load Current Draw” (links below), I am now considering using a small pure sine wave inverter to partner with my small battery.

To put it simply, electrical engineers are recommending not to oversize the inverter because some inverters will consume a lot of power “just being turned-on (tare loss)”. Fortunately, the solar seller recommended by ma’am TS (ma'am jayrene) have available stock. I’m going to test using a small inverter to see if it will really improve the battery runtime. I will post the result of the test here.

For sure it will... that's why I bought few months back a small 300 watt inverter sa cdrking, to avoid using my big inverter when I just have my laptop plugged. In summer it is not so obvious but I think it will be really a plus to have it now that the rainy season is here!!

@quark

Kaya nga sir binigay ko yung P300 na link.
Nakabili ako a few months before na mas mahal at P350.
I know puro china iyang LED solar lights with battery....but may branded na china product at generic.
Nabili ko both kinds kaya alam ko at na compare ko.
Of course mas maganda quality ng branded na china product.
If on mo ng 7pm aabot pa ng 5am next day basta full charge and hindi full power.

Yung mga 220v LED bulbs na binili ko sa CDRKING ilang buwan lang nasira na. Napalitan ko yung iba but di rin nag tagal.
Early adopter ako ng LED bulbs....noong unang labas at mahal pa bumili ka ako. Iba ibang brands.

hehe... that's exactly what I was thinking when I saw that my big inverter was "eating" so many amps! Maybe I will buy a small pure sine because the 300 watts sa cdr king won't run my led tv! In rainy season, it's always nice to save some amperes!

Re: How to make your own home solar. With Pictures + solar b

sir bongalzate...ok naman yung nabili mo ah?... ito yung specs sa net...

Model Number: UNIV-1000P, Efficiency:90%, No Load Current Draw: <0.8A

...therefore, 12v x 0.8A = 9.6 watts... mababa nga eh... di tulad nung sa akin na cdr king (pure sine wave) 1000VA, ang reading sa watt reader ay 36 watts!... imagine "standby" pa lang ay 36 watts na ang power consumption... huhuhu... kaya pala yung 65Ah car battery ay ang bilis ma-discharge.... napabili tuloy ako ng 350 watts pure sine wave ASAP! kay ma'am jayrene (seller ng aquaphonics ni ma'am TS).

ahh ok. thats a relief didn't bother to compute but the article posted in the forum is nice. thanks

Re: How to make your own home solar. With Pictures + solar b

good pm po, mga ka-solar ko, baka po may nakagamit na po jan sa inyo nung TBE pure sine wave inverter, parang iyun kasi ang pinaka-murang brand na pure sine wave, balak ko po kasing palitan itong modified inverter ko, pa feedback po kung meron, salamat po

sir batangburgos... parang walang web site ang manufacturer ng TBE pure sine wave inverter... ang hirap i-google ang specs.

hehe... I was about to ask the same question as I want to buy a smaller inverter... I saw on Olx for a 300 pure sine, the cheaper is 2400 pesos... but like you, I don't know the quality So up for this question!

for info: I just see on youtube a video where a guy tested a 500 watts cdrking inverter with a "kill-a-watt": the inverter consumes 35 watts!

How to choose “Made in China” inverter
Source: http://www.dmdpower.com/newsen-show-1575.html

1. There must be a Chinese manufacturer’s trademark. Factory address and telephone number must be printed on the package.
2. You must choose metal shell with added fan products. Metal shell has good heat dissipation characteristics and also won't burn. Added fans help in cooling, although it increases the noise.
3. Choose the SMD (Surface-mount devices) over the older through-hole technique devices.
4. All kinds of protection function must be present (example, over voltage, low voltage, over temperature, overload, short circuit, reverse connection protection. It must also have sound and light alarm, to remind you to deal with situations in a timely manner.
5. Conversion efficiency: This is a very important indicator of inverter. If the inverter efficiency is higher, it would mean longer battery run time and lower inverter heat. In general a good inverter should be in 80% to above 90% range. However, users can't test this and can only rely on the manufacturer’s conscience. A good test for a user is to load the inverter with high power for long hours and feel the temperature of the shell.
6. Seat should use bakelite material. Plug wire length should be easy to use. Bakelite material can work under high temperature conditions without deformation and also won't burn. Bakelite appearance is bright, plastic material will look dull without varnish.
7. If the load is greater than 160 watts, the inverter must be connected directly to the battery via the battery clip or better. Car cigarette lighter socket can only withstand around 10A current.

Note: I re-translate the "nosebleed" English instruction from the link above.

Re: How to make your own home solar. With Pictures + solar b

during the time when my 1000w modified sine DOXIN brand was busted. I also was tempted to buy TBE because the price seems to fit my budget. But as sir tristan says I too can't find additional info about the product. But with its look I think they are manufactured the same as my busted Doxin brand or if not parts are identical. (they are perfectly the same outside)My busted Doxin brand is bought about almost 3 yrs ago when they first came out as a car accessory. with in that time I only used it when there is power interuption to power lights and fans at night so it is not abused. then when I started my solar project last dec 2013 I used it to power my led tv and ps3 console and last month it just stopped and the fault led just lights even if the connections are all in order. So thats it thats what I can say with that inverter. just want to add that I acquired my UNIVPO inverter thru a "kababayan" which I happened to browse at OLX when finding a replacement inverter he said that TBE is untrusted for him (he is a SALESMAN) then offered me to purchase that UNIVPO in 2 payments which I agreed instantly with out thinking though it is also a china made product I just wish that it will be worth the price.........

Thanks! and thanks for the translation The problem with the chinese is that even the spec are fake!! So it is like playing poker when we buy a chinese made item!

I'm sorry but this not possible! Aircon are great electricity eaters and unless you have a very big budget, you cannot run it on solar...
here is an example I gave last week, on this thread:

for only one hour of use of one 900 watt aircon you will need:
300 watt solar panels
200 Ah deep cycle battery
+ big pure sine wave inverter and controller
It's a minimum of 50000 pesos expenses

Yes, i agree and it is mentioned in number 5 as "However, users can't test this and can only rely on the manufacturer’s conscience."

... i-add ko lang na OK yung ginagawa ni @batangburgos na humihingi muna ng feedback sa mga forums na katulad nito bago bumili...

Result of the testing:
June 23-24, 2014: I connected the 350W pure sine wave inverter to a fully charged 100Ah motolite solar master and run it continuously with a load of 83 watts from 8:30AM to 2:30PM (6 hours)... output voltage 220VAC is very stable, the cooling fan is always running; external shell of the inverter is NOT even warm to the touch; very significant increase in battery runtime (additional 2-3 hours) as compared to a cdr king 1000VA pure sine wave UPS/Inverter.

Re: How to make your own home solar. With Pictures + solar b

Hello Ma'm,

Why don't you try Souer brand. Pero wala ata sila pure sine wave na inverter.

http://www.olx.ph/index.php/classifieds+directory/q/souer/province/Metro+Manila

http://www.chinasuoer.com/products_detail/&productId=84.html

This is what I use for 220v electric fan. More than 6 hours use daily ok pa naman: SAA-500A 500W kaso di pure sine wave.
Nabili ko 2nd hand but the store is in Taguig sabi sakin.
