Cant self consumption first?

How to see import double record?

why need to manually switched off at 4pm?

With smart meter they can tell got unauthorized export... Okie....
Most that install using the nem3.0, using contractors, also have seda  approval right?

I should stop trying to find excuses, anyhow being patient is a virtue.

Main problem is those secretly connect without applying for NEM.

If the meter got the 51 reading then no need to change meter?

Quite surprised that it's not that far off from a 9.68kwp with 8kw inverter system. You got a chart of production throughout the day for good n bad days?

assuming no major failure after warranty period,  450% over 25 years from rm500 mthly savings.. break even on 5th year

thats interesting... i am on the same boat with you. here is the wiring diagram...

So, after seeing some feedbacks on microinverter setups, are there any suggestions on either single-phase or three-phase microinverter is better to use on three-phase house? Is the power export based on load per phase?? Does it mean, I may be exporting power because the generated power being connected on different phase while consumption at different phase? Or the import/export meter will be smart enough to calculate?

Not much different except for the MPPTs.. HMS comes with 4 MPPTs while HMT only 2MPPTs.

Also maybe HMT has better load optimization.

It is of course better to use 3-phase  microinverter if possible because it is more balance and future proof once the NEM lapse.
On another note.
The smart meter by TnB does not calculate per phase, but the overall. My understanding based on 3 phase string inverter is that it will output the electricity to 3 phase equally, but load in our housewhole is not equal, so in the end some phase maybe exporting while other phase maybe importing but the TnB meter will record the total of 3 phase. It will not show individual phase load or generation.

Installer said, for my situation, it's because that microinverter signal couldnt reach the DTU so no data sent. It is actually still working. In other words, DTU displays real time data. So anything that signal couldnt send through, data will not be captured. Meaning that the yield i see on the app will be lower than what my system is actually generating.

I have moved my DTU to a more central location yesterday. Today seems better, no more offline issue. Still monitoring.

There wasnt much info on HMT available online so it was a judgement call to go w HMT. Figured might as well go 3phase to 3phase. Must be a reason they came out w 3phase, if not could have just offered 1phase solution for all if they both work the same. I dont mind the additional safety features, to me, better be safe than sorry.

If you dont mind me asking - what kind of anticipated issue? Mine's 2.5 storey and i have panels on both 2nd and 3rd storey roof...

so for 3 phase HMT or HMS?

based on the datasheet, HMT even though for 3phase, but it is more suitable for commercial/industrial applications.

really??
coz my neibour say if the dtu offline, tnb meter will not count your export. And it has happened to him.

I'm not too sure if we are on the same page.
But I don't think the TNB meter calculate each phase individually, even if you charge your EV in the phase that has now solar generation and if importing but if your net electricity usage is lower than generation, it will still consider as export. That is what I think

All of the components, DTU connection, daisy chain connection, connectors, zero accessibility to rooftop, 3 storey that requires skylift, it’s just my own evaluation I don’t like uncertainties. But I do recognize the advantages of the technology and dc conversion and decentralisation

Got.
I have four battery packs.

280ah x 51.2v = 14336wh (14kWh)
280ah x 51.2v = 14336wh (14kWh)
314ah x 51.2v = 16076wh (16kWh)
200ah x 51.2v = 10240wh (10kWh)

Guys, there’s one thing I want to understand. Let’s say my solar panels generate 300 kWh during the afternoon. The energy generated will feed my grid first for my own consumption, right? If I only consume 200 kWh during the afternoon, the remaining 100 kWh will be exported.

So, my question is, will the TNB bill show an export of only 100 kWh instead of 300 kWh? If yes, this mean TNB bill export information reflect the net amount, not the total energy generated from the solar power. Am I right?

Anybody using Huawei inverter here?

My MPPT1 and 2 has a huge difference in terms of voltage. Both have equal number of panels. I do not think it’s normal. Want to exchange notes

Same side. No shading whatsoever, terrace house all level. I will ask them how they wired the panels later.

I check morning, noon, evening. MPPT1 is always higher than MPPT2 in terms of voltage, amps will be close.
