oh...
does it mean the convertion will make my harvested solar power even lesser?

Depending on the efficiency. Most of the things you can get in taobau, but you have to get quality or buy and test. Price definitely cheaper than buying here in Malaysia.

in the end, not sure how much it will cost


btw, i dont think my condo are suitable for solar harvest..

maybe can try with wind turbine...

If your corridor have enough sunshine (>6 hours) is possible. But wont be able harvest much unless your corridor are big.

corride and balcony are quite big,
but i dont think im going to occupied them with those ugly panel...

Yup it work. The problem is the switching. Only electronic switching is able to get to that speed.

And the cost is killing.

Malaysia not worth that kind investment. Battery will kill you first.

I don't think we can see these technologies as an investment. Malaysia doesn't have the brains enough to explore the potential of alternative energy. But if and when electricity prices soar, then we will have the market for it. But at least we prepare ourselves for it first.

@ozak do you know anyone with the knowledge for that?

This kind of thing in here normally DIY.

The nearest I can thing of is those solar panel installer. But they might just a standard installer. If out of their scope, they don't no liau.

Why you so keen to make this ?

Another problem putting suck amount of batteries, and not common devices will risk insurance not covering your house coverage if there are any fire and Bomba blame that to the setup. Unless is install by "authorized" installer.

Future protection. And since I'm building my house from the ground up, plenty of things I can play around with, rather than having to knock walls or lay cables. All can be pre-built nicely. Not to say I want to go off grid but if disaster struck, I won't be caught without water or power for at least a few days.

You can lay down the foundation 1st. Like wire running place that you can access later.

The main wiring that you can modify easily later. You need to draw out the plan.

This kind of protector can be do later.

I do have such plan initial. After I check the utility history, electric is still consistence than water. Where water are more effect by the weather. So I plan and modify the water supply to able reserve for few days. For 20yrs so far, I don't have water supply problem even drought for few day.

For electrical, it is not that critical. But I do have plan for this. At the moment, only 180w panel have been install and backup by 65Ah battery. Probably only 5% of my total usage electric been taken out. Step by step to increase it. At the moment too lazy to do. And the cost too.

For water, I have an underground tank holding 105,000 gallons (?forgot the actual amount) which will be connected to all the flush toilets and also the sprinkler and outside pipes. And another filtered rainwater will probably supply the washing machine.

Now left with this solar power generation and storing in the batteries. Not for a lot of things, maybe the Internet modem, fridge, a couple of lights and a few fans. And some plug points and to one of the TV sets. So not really a huge setup. Too bad the FiT thing had a limited run. If not could have maximise the returns.

this company still around i wonder if they're reliable?

FUh i always dream to have 100% off grid home

That is quite alot of thing to be run.

If intend for emergency backup, you have to slim down the appliances to be run. Only run necessary thing.

FIT is mean for selling the supply to TNB. You can't tap the power from it.

At least with FIT we could sell it back to get back our investment and when the time comes, switch it to charging our own batteries. Anyway, that is water under the bridge now, so back to storing in batteries and using it. With the way things are being run in this country, only a matter of time before the electricity increase in price.

Price increase also not that so high. Increase 2x also will take more than a decade. I won't be worry about it.

You can start like take out 1% or 5% OFF of your bill to go off grid. Start with small and see how.

Guys, need opinion.

I am putting >200 sqft of awning in upstairs front porch.
Mainly to block off sunlight n cool down masterbedroom.

I reckon there will be 4 - 5 hours of sunlight.

If I lay solar panel on top n link to some batteries, batteries can store outside alongside aircond compressors.

1.can generate enuf juice to power say a dozen led light at nite n a couple of fish pond pumps 24 hrs?

2. Estimated cost? Not planning to fit or nem, too complicated. Mote of joining the green cult.

3. Can diy without getting myself fried?

4. Safe or not? Can burn down house or invite lightning ?

Thanks in advance.

>200sqft about 1.2kw panel.

A dozen of led bulb running for 8hr - 12x12wx8hr = 1152whr

3 of fish pump 24hr - 3x20wx24hr - 1152whr

You need

1)1.2kwh panel
2)275Ahr battery - 4 series, 3parallel - 48v
3)21A charge controller.
4)inverter

Probably about RM30k.

Can DIY if you know.

Safe is depend on how you design the safety protected circuit.
