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

[raypaz]

sir raypaz... personally, ito ang concern ko "umaabot lng ng 13.0v at flashing na ang green led" ... ilang oras bago ito mangyari?... may problema kung hindi umaabot ng 14.xx volts... lalabas na "chronic undercharging" ang batt at posibleng sulfated na, kaya mabilis na ma-discharge... testing mo i-direct charging ng panels mo, kung aabot sya ng 14.xx volts or use AC charger to check kung umaabot ang voltage charging sa 14 to 15V.

yung sa akin kasi ay 2 x 80W panel >20A scc >100ah solar master... ang pinaka-mabilis na full charge ay 10AM at pinaka-mabagal ay 3PM if makulimlim... sa range na iyan, palaging aabot muna ng 14.xx volts tsaka bababa sa 13.xx volts (float) maski malakas pa ang araw.

sir tristanws....before noon flashing green na sya..sinunod ko advise ni mam awinahe...ngayong hapon at umabot nga ako ng 14.1v..kaya lng overcast ngayon dito sa amin...kaya confirmed sir problema talaga scc...tsm

@madame awinahe
how's your alum batt going? I still don't have the time to try a new alum batt but I already have the 3sm size battery. Maybe this week the boys(2 anak ko) will be going to the seminary (kahit sana mag-pari ang isa) for the school opening then all time is my free time already......

 

[poseidon]

Kamusta ang mga solaristas?

 

[tuffoman]

may bago ako dagdag sa system ko. meron kasi 12AH na battery si CDRKING at P990 lang but if yung regular brand P1,999 yun. bumili ako ng isa to power my CPU fans magdamag hanggang umaga. 5pcs case fans kasi yung CPU ko at may led lights lahat. Satisfied na nman ako kasi less gamit kuryente na galing sa 220V socket.

 

[poseidon]

May nakapag convert na po ba dito ng tattoo home LTE modem(12v, 2A output) from AC to DC? Puwede ko kayang gamitin itong 1.5 A output DICK SMITH universal car adaptor? Mababa ng 500mA (.5A) ang universal car adaptor.

 

[TristanWS]

sir tuffoman, da king 12AH battery for P990... aba eh murang-mura ah... makabili din nga... halos 2K din ang 12AH dito sa location ko.

sir poseidon... tingnan mo ang adapter ng modem kung may naka-drawing na positive/negative... kung meron, eh pwede yan ikabit sa "load terminal" ng scc... huwag lang lalampas sa rated amperage ng scc ang total DC load mo.

 

[poseidon]

Thanks Sir Tristan.. Intayin ko muna mawala ang bug sayang din

Salamat may ganito pala na thread, tagal ko na kasi gusto umpisahan kaso hindi po alam kung papaano gawin. May tanung lang po
1. Ano ba maganda na inverter yung 12 or 24 volts? Ano ba cons at pro?
2. May solar master ba na 24 volts?
3. Paano ba gawin yung apat na 100ah na batteries na maging 24volts na 400ah?
Salamat sa pagsagot po. Newbie lang talaga.

Sorry to answer so late but I'm busy these days and not often at home... that's why my alum bat is still "resting" I did not use it and did not recharge it but the voltage is still 10.95... The problem also is that I have no use of this too small battery so I don't want to use my 24 amp ac charger always and as I consider this experiment positive I will now wait for an occasion to find a bigger one (at least 40 Ah). But I am still very interested in your future experiment

In a solar setup everything should be at the same voltage... your panels, batteries, controller and inverter. There is no quality difference with an inverter 12 or 24 volts. A 12 volt inverter works with 12 volts battery and a 24 volt inverter works with 24 volts battery!

As far as I know there is no 24 volts SM battery.

You cannot have 24 volts 400 Ah with 4 x 100 Ah 12 volts batteries. If you connect your batteries in series, you can have 24 volts 200 Ah and if you connect them in parallel you will have 400 Ah in 12 volts.

You can see how to wire batteries here http://www.batterystuff.com/kb/articles/battery-articles/battery-bank-tutorial.html

Here, in the Philippines, for a small home solar, 12 volts is better because it's difficult to find appliances in 24 volts...

If you have more questions, don't hesitate to ask!

@madame awinahe salamat po sa mga sagot. Ano po ba talaga maganda na battey gamitin para sa off grid? Para sa inyo mam ano po na brand maganda na inverter at controller na gamitin kung may aircon ka na 1hp?

@madame awinahe salamat po sa mga sagot. Ano po ba talaga maganda na battey gamitin para sa off grid? Para sa inyo mam ano po na brand maganda na inverter at controller na gamitin kung may aircon ka na 1hp?

If I had a 1 hp aircon I will not use it on off grid solar because it's way too expensive
To give you an idea of what you will need to run 4 hrs a day your aircon, in a traditional off grid way, here is an estimate:

600 Ah SM batteries
1200 watts of solar panels
60 amps MPPT controller
1500 watt PowerStar inverter
Plus wiring, fuses, breaker.... let's say all-in-all it will around 150 k for 4 hrs use per day

If you are a Meralco consumer, you better go with a tie grid system if your aircon is used mainly in day time

You have also a cheaper solution with the new hybrid inverters... they have a buit-in MPPT controller and can run directly the aircon from the solar panel, and in the same time can charge your battery... the cost could be around 120 k but you can run your aircon almost 20 hrs a day! I have not yet use or see in real life these new hybrid inverters, but it seems to me that they are now the best solution for medium scale solar setups.

 

[TristanWS]

Because of the problem in applying for net metering with the electric company, "intelligent hybrid inverters" are becoming more popular in the Philippines... because you can use it in the following working modes:

1. Off grid
2. Grid-tie
3. Hybrid mode or dual functionality
4. Back-up or UPS mode

Example from aliexpress.com: 48V 3000W, price US584.38

ASK THE EXPERTS: Batteries in Series & Parallel
By: Hugh Piggott, December / January 2008
Source: http://www.homepower.com/articles/s...llation/ask-experts-batteries-series-parallel

What happens to the battery bank capacity, and the charging and discharging characteristics, when you connect a 12-volt (V), 100 amp-hour (AH) battery and a 12 V, 200 AH battery in series? Conversely, what happens when they are connected in parallel? - Sid Baxter • Pocatello, Idaho

Connecting two battery banks of different amp-hour capacity together in series is a bad idea. The problem is that the battery charging controls will operate based on the average battery voltage and the two batteries will have very different voltages because their capacities are different. The 100 AH battery will become fully charged long before the larger one. The combined voltage will rise, but by the time the controller turns off the charging sources, the 100 AH battery will be overcharged. Meanwhile, the 200 AH battery will not get fully charged. When the bank is being discharged, the 100 AH battery will go flat and its voltage will fall well before the 200 AH battery. The inverter will eventually cut out but not before the 100 AH battery is excessively drained.

Connecting two banks with different capacities in parallel is technically fine since the batteries will be operating at the same voltage. Charge and discharge current will be shared, based on capacity. It is best if the batteries are of the same type and age. For example, avoid combining a sealed (gel or absorbed glass mat) battery with a flooded (conventional) battery because they have different charging setpoints. Broadly speaking, you can parallel batteries without problems, and the charge controller will look after them. Just make sure you give them plenty of charge. If the system tends to operate at less than a full state of charge, adding new batteries to old will probably just result in the old ones pulling the new ones down and everything getting sulphated.

Madame awinahe, Kaso wala pa dito sa amin yung tie grid system, ang meron lang rotation na brownout 5 hrs sa i sang araw, minsan dalawang beses pa.
Paano yung mga hybrid na inverter puro mga 24 o 48 volts na....

Salamat po tristan sa info na ito, balak ko kasi magdagdag ng battery kaso naguguluhan ako kung 100 o 200, kasi 100 yung gamit ko ngayon.

 

[TristanWS]

sir fleettkr... grabe pala brownout dyan sa inyo... 5hrs 2x a day... dapat i-identify mo ang pinaka-mahalaga i-power para sa iyo... tapos i-design mo ang setup base sa pinanaka-mahalagang power need mo... halimbawa yung sa akin... ang pinaka-mahalaga sa akin ay internet connection dahil ginagamit ko sa hanap-buhay... tapos ilaw para maliwanag ang working area at dalawang DC fan para pang-laban sa init, total load is <150 watts... ang design ko ay;

* 1000w UPS/inverter from cdr king >70Ah solar master = battery runtime 4hours max
* 160w panel >20A scc >100Ah solar master = battery runtime 6hrs max
* 100w panel >10A scc >70Ah solar master = ginagamit for night lights (12V DC LED) and 12V DC monitor camera (6PM to 6AM)
* dalawang solar power kit from cdr king, 20w panel >12Ah battery = portable back up setup

hope this will give you the idea...

...regarding combining batteries, wait natin si sir bongalzate... tatlo ang 100Ah solar master nya.

@tristan, kaya nga po mahirap talaga, yung mga tao dito puro generator gamit nila kaso ang ingay naman. Gamit ko lang kasi ngayon isang SM100ah at 1500 watts na inverter. Nag cha charge ako ng battery gamit yung sa car charger wala pa po akong solar panel. Gusto ko kasi isang bilihan lang na pa konti konti ang upgrade. Naguguluhan kasi ako sa inverter kung ano ba maganda 12 or 24 volts at kung yung mga hybrid ba o yung sabi ni madam awinahe na powerstar kasi po baka magkaroon ng tie grid system yung supplier namin pero malabo pa. Balak ko kasi 400ah na battery tapos 600 watts na panel muna kung kakayanin sa load na 700 watts
*AC na 0.5hp mga 4hrs
*led na tv 75 watts mga 3hrs
*led na ilaw 50 watts mga 4hrs
*e-fan na 120watts mga 8hrs
Hindi ko alam kung kaya yan sa initial na setup kasi kung hindi bawasan ko muna yung oras sa paggamit.
