Your solar is under which NEM? If NEM 3.0 then definitely your understanding is totally wrong, the extra 200-300kwh is accumulated in your NEM BAKI ACCOUNT balance until 31 Dec of the year, if you don't consume it within the period, TNB will write off the extra balance in next year January bill.

Mine is TNB 3.0 like the other guy explained to you

Checked your TNB bill, think your December 2023 Bill now appear with "NIL" amount of NEM BAKI, maybe you check your November 2023 TNB bill then you will understand

Yes we do used the generated kwh during day time but it's to offset TNB import in figures.

I am sure we can't used it directly because the TNB meter not that smart to balance the usage between import and export energy used by our home appliances fluctuation. . It can offset the number je.....

Power coming out from solar panels are DC.
Your EV charger is drawing power from AC.

1) you need something to convert DC to AC.
2) you also need extra energy source to stabilize the AC output in case the solar panel was block by cloud for a short time.

If you dont plan to use TNB's plan, a hybrid inverter with 48v 50ah lithium battery should be enough if you only do charging at morning.
btw, how big is your EV charger?

If our inverted can do it, why can't during blackout period? Simply because our inverter cannot cater for direct usage.

Show me where its said this "Yes, u need to have Tnb supply to start generation. But that only to start. Once ur system produce enough, u don’t draw from Tnb anymore. "

I connect them to my 2nd floor DB ... So my ground floor not using solar energy? They do travel backward to the meter?

I don't have an ev yet but the only factor in me getting it is to charge it solely on solar. It defeats the purpose of having a clean car if I'm using it via the grid so I want to get th facts right with solar panels

So to really ensure my ev is powered by solar and off grid my set up is this?

Solar panels (DC) > battery > wall mounted charger (ac) > ev?

If I don't wanna spend on a battery

Solar panels (DC) > converter > wall mounted charger (ac) > ev?

Second set up only allows me to charge during day time only right?

I don't have EV charger myself  but I believes those wall box EV charger draw power from TNB (230v) then convert to DC (800v) to charge the car.

If not mistaken, wall box is also ac.

It’s either 7kwp(single phase)
11kw or 22kwp (3 phase)

Agree. Solar first but the cost of set up for 10 panels around 15k

But since I have a battery in the system. I can reduce the panels.... Right?

Sorry, I misunderstood your earlier post, thought you meant the difference of units went missing.

Yes my generated units in solar app has been higher than the  export unit recorded on the bill.
My apology for didn't read the post properly.

Hi sifus. I was proposed bifacial solar panel for a tiled rooftop installation. However, based on my understanding, to maximize bifacial gains, you would need to install the panels on an elevated racking system to allow the back panels to capture light. Would I be better off installing non bifacial panels?

No , you have to consider whether your inverter is a 3 phase inverter or a single phase inverter.

Most installer want to sell cheap , and consumers do not know , so they only use single phase inverter. If it is single phase inverter, the inverter will only offset one of the phases. It does not offset all phases.
The other 2 phases will not be offset during the day time and continue to consume from the grid.

That's why when the1500kwhr ruling came out , some of the solar owners were charged because they were still using 1500kwhr from the grid.

a micro inverter does not offset all 3 phases at the same time.

but you can assign different microinverter to different phases , but a single microinverter DO NOT offset all 3 phases a the same time.

Then you go and whack your solar vendor/installer, they are the expert and not advising you properly.

Nope.  Most inverter sold now is single phase inverter connected to only a single phase in a 3 phase system.

No because it is all clearly stated in the quotation and there is no safety issue violated.
They can argue that they are meeting your budget and the model and brand name is all black and white in the quotation.
If the quotation looks like this:-

3. Solar PV Module
+ Trinasolar TSM-DE17M(II)-455W / Canadian Solar CS3W-455MS    X14 units

4. Solar PV Inverter
+ Solis Inverter 1P6K-4G        x1unit

How many people here will notice this? How many people are technical enough to realise based on above that this is a single phase inverter?
How many people do you think even have the knowledge to know even what an inverter is?

The same also for solar panels . How many people will realise if the solar panels given is tier 1 or tier 2 panels.

I recently finished my solar installation using hoymiles micro-inverter.

But installer does not want to provide me with the end user username and password for hoymiles s-Miles monitoring app system saying its only for there own usage. Instead have to rely on there own app for monitoring with minimum info.

You think i can go to consumer tribunal to force them to give me the access to hoymiles s-Miles monitoring app?
