6.34kWp/5kWac
Trina panels, Huawei hybrid 3 phase inverter

Got it for RM19800 during promo. Should be installing next month. Just signed the NEM forms on Tuesday.

Sun2000 5KTL-m1

Ppl will say battery expensive
Ppl will say need to use proprietary Huawei battery or only those approved by Huawei so it’s expensive

My answer is very simple
IF the price is the same or just very slightly more, for the same 5kWac of course I take the hybrid inverter

Why? I have the OPTION available to me to easily plug in a DC battery. Which incurs less setup cost versus your AC coupled battery. Not to mention less losses since it’s DC to DC battery.

Battery expensive is not relevant. I have the option to do it when it’s cheaper in the future. Even if AC battery is cheaper in the future you need to incur additional setup and commissioning cost for the AC coupled battery setup. So nett nett I will still come ahead with less hassle.

logically possible. but why don't you ask the solar installers and share...

how to know if its low freq or hi freq?

I don’t want to be off grid. I want to be on grid with battery so can use my own power after NEM expires.

Who changes inverter after 10 years lol. If it’s not faulty and nothing wrong why want to incur cost? 10 years time battery cost would have come down, and just buy a Huawei battery, plug and play and I am ready to rock.

My payback period for solar system is <5 years. After that savings for another 6 years would give me sufficient returns to buy the battery, just in time for NEM expiry.

There is absolutely no reason to buy a normal string inverter over a hybrid Huawei inverter if it costs the same. If the hybrid inverter is slightly more, just pay it. After all Huawei is one of the better China inverters out there.

Anyhow the only reason I pull the trigger now is because solar systems have dropped significantly in price. Plus the Solaris RM4k rebate lowers the total cost. And the company offers 0% credit card installment, which is bit more than my TNB bill. No brainer for me to pull the trigger.

After paid up it is “free” electricity.

PM me your contact I’ll hook you up.

Panel is okay. But I would avoid those inverters like the plague.

Good brands for inverter from China includes Goodwe, Solis, Sungrow and Huawei.

Search, Australia forums and groups are a good resource.

Learn from other people’s mistake. Don’t need to have bad experience in everything lol. We have abundance of option in Malaysia and Solis & Goodwe + Huawei are solid choices.

In any case, that’s just my personal opinion that I would avoid it like the plague. I would avoid Peugeot cars too. But anyone can go ahead and buy with their money.

That's a single phase inverter. Is your household supply single phase or 3 phase? If 3 phase, always best to choose 3 phase inverter.
I got 6.37kWp with Huawei 3 phase 5kW hybrid inverter for about the same price. Which is why I say for the same price & kWp, take the Huawei inverter.

Just checked..
NEM submission 17th May, approval 28th May. Not bad. Now waiting to queue for installation date.

The panels are fine, I would however opt for a better inverter if it was my system. A GoodWe, Huawei or Solis. Also, my vendor don't charge me extra for EPP 36 months, so if comparing the system of the same size + Huawei 3 phase hybrid inverter and 36 months EPP... nope, your quotation is not the cheapest, just FYI.

Not sure if you noticed your own quotation. Despite both using the Huawei hybrid inverter, the VASOLAR one is 8kW and the earlier one is 10kW. Given the total system size the VASOLAR one is more optimised. Given the price difference and similar kWp output, VASOLAR is a no brainer IMO. At RM2994/kWp with EPP, very competitive pricing!


lol what you talking. the inverter make all the difference. panels have matured so much and between major manufacturers performance numbers are very similar. inverters on the other hand lead a hard life and fail more so than panels.

And his first quotation stated SUN2000 which is the Huawei hybrid inverter.

https://services.seda.gov.my/nem/quota/dashboard

NEM rakyat quota 30% left… we are only in half of the year.. Solaris working its magic. I’m chilling because NEM agreement signed and allocated for me.

You guys better hurry up if you want to install this year.

Not worth it for a consumer. Many solar vendors out there offer EPP credit card payments at 0% (some with surcharge) upto 60 months which is 5 years. if you calculate the entire cost/sum paid, it is much more expensive for such rental/instalment plan. Because at the end of the day, somebody is financing the capex, and there is no free lunch in the world.

And depending on the vendor, the warranty period varies. In any case most all inverters and panels are warrantied for >5 years.

How much did your system cost per kWp? 3 years is amazing.

Alpha.. the sales person don’t even know what is “data sheet for panel & inverter”

Answer me her quotation is suitable for my tnb bill and ask me brochure?? I don’t want brochure, I want data sheet. Brochure got rubbish i don’t want to read.

Then say revise quotation and never come back. Very unprofessional.

For something I spend more than RM10k on. It is crazy to even consider Alpha. Like pasar malam.

Today installer came to install the system at my house. Very professional, they are seasoned pros and know exactly what they are doing.

9am start work after some chit chat. 2pm all done.

Very happy with the installation of my inverter, decided to put it outside my porch with space right below it for batteries 10 years later.

ERS. PM me your name and contact I’ll get them call you, VIP treatment. They are very busy and swamped now as with all other installers.

Price is competitive but most important for me is that they install 3 phase inverter for my 3 phase power. Some installers will insist single phase inverter is fine (it is, just not optimized for you!).

Micro inverter is not superior to string, each has pros and cons.

Unless you have shading issues, going with string inverter will be cheaper for same kWp. I would suggest you to get some quotes and compare.

If you want battery better off getting a hybrid inverter like Huawei, then add in smart meter and you can even be powered up when TNB grid is down.

Why micro inverter? No shading better go for hybrid string inverter, more bang for bucks.

That’s very expensive. VERY.

1. RM4.6k per 1kWp — wtf
2. RM3663 per 1kWp

I did mine 6kWp system ~ RM3.2k per 1kWp. Smaller system than your 2. And cheaper. Trina Vertex S+ panels with Huawei hybrid inverter which costs a premium over normal string inverters. If you need help DM me I’ll hook you up. Now they super busy no time layan ppl asking for fun.

Quota left < 8% now. And is it cash price or credit card EPP?

And pls don’t just look at the kWp number. What panel, and especially what inverter is more important.

Inverter works very hard. Over 60C internal temperature, and it needs to do this everyday.

My 6.86 kWp with 5k inverter can hit 5.5kW on sunny days, but some days don’t. But I guess it’ll pull the average output up.

That's RM3552/kWp. They gave you a good inverter, Sungrow, single phase. If your house is 3 phase then.. not so great.

Cheap.. hmm, I won't say so, but your inverter is now underrated, you can add more panels inf future if your electricity usage increase or you change to an EV.

Well, shouldn't take Solaris rebate into account when comparing cost between systems, because 4kWp system will always nett the highest savings/cheapest kWp price WITH Solaris rebate. So it's not a true apple to apple comparison.

Anyway they did give you a larger inverter, you are future proof upto 7.8kWp with oversize panels, more than enough for single phase house. Good job!
