wahlaooooo, ok confirm on-grid since meter also can pusing terbalik.

Is it legal to install grid type inverter to connect to main? do we need TNB certified installer to do it?

Its illegal to temper with unless you are approved to feed back. Check SEDA website.

And it is not as simple as feeding back = money. TNB only offfer a very small quota every year.

Is ok, will test out first once in "production" I will build another unit. Since I am planing to put multiple cctv with self power. My last test using a basic USB watt meter (pi power via usb), it only take 4watt per hour.

got myself a 50watt instead, waiting for delivery. About a month.

This is in grey area. TNB don't have such rule.

There is nothing to temper to any TNB equipment. And there is nothing to install at all.

The inverter is very simple and just plug the 3pin plug into any wall socket. That's it.

It is not encourage to do so. Because when there is no power coming, or the TNB no supply, the power will flow to the main line. If some technician doing some repair work on the line, which they thought they already cut the power.

But the new inverter in the market now will not ON or no power generate if there is power cut off. It is pretty safe.

No bad.

Quite cheap.

Yeah, with the Prime member my delivery from China to Malaysia is RM 8.80 + Local delivery RM 8, ok lah.

The inverter just plug into 3 pin wall socket? this will bypass the RCB, kinda dangerous.

Why dangerous?

Your 3 pin wall socket don't go through RCB ?

The 3 pin wall socket connect to MCB, now the MCB receives AC via 3 pin wall socket coming from inverter, if the nearby or the same MCB has current leaking, will the RCB detects the current leaking? it probably not.

Bro, TNB is a private entity, they dont make law. You backfeeding without permission is breaking the electrical supply act. Not only you could overload that particular plug. You are also energizing your neigbourhood local circuit and could kill people during power down maintenance. Granted your system is small at this point.

But the new inverter in the market now will not ON or no power generate if there is power cut off. It is pretty safe.

It will function as usual if power leaking.

This is supply but not power leaking.

If the inverter is short, it will still trip. And any thing that is leaking.

I know what you mean. But if your inverter is not sirim or NEC approved, better go over a power relay plug.

My Cheap China Solar charger controller and Panel.






After test few time, i accidentally reversed polarity of the batter. Damn. The Solar Diode is fried but still able to chunk out power. Hope no damage. The Charger controller still power up, but when i measure voltage it seem output too high now, will need to look into the circuit if I can fix it or not.

That panel look like 30W?

Won't easy fried wan la. That charger controller don't have polarity protected ? If kena fried, it should be the charge controller spoil 1st.

Diode function is also protect wrong polarity. How to fried it. Accept too high amp/voltage pass thru.

The charger controller have the Algorithm volt to charge the battery.

Car battery very high current

That panel is ratted 50watt, but i have no chance to test till that usage.

You mean discharge current? That is a car battery. Definitely discharge current is high.

If you talk about charging current, normally charge at C1 or C2. Which is if the battery is 65ah, charge at C1 = 6.5A. Don't think the 50w can output that hieght.

What you need to takecare is the charging voltage. That can kill the battery.

Cause the panel can output as high as 19v.

I accidentally connect the batter in reversed polarity, and fried the diode on the Solar Panel. Now I suspect the controller also "gila-gila" already. Will need to wait for another controller. BTW I also planing for PWM Arduino carger unit. Now collecting/buying parts for this project.
