19.5kW Hyundai Vs 12.32kw LG system

Solar Panels

I am tossing up between 19.5kW Hyundai VG Series HiE-S390VG Vs 12.32kw LG NEON H 385 watt system.

I have 3 phase running to the house and shed, both quotes have a BYD battery.

They both quoted the same inverter (Fronius Symo GEN24 Plus Symo GEN24 10.0 Plus (10kW)) however, the larger Hyundai system includes another 5kw fronius inverter (10kw + 5kw)

I know the LG has better efficiency and less performance degradation however, the Hyundai still has 84.8% guaranteed after 25 years… so wouldnt I be better off going with the Hyundai system because it has more potential engery gain?

@cleo that’s a good comparison.

Both quotes are very good but considering the huge difference in size (kW) I’m wondering what your consumption is and why they would vary so much? I personally rate the Hyundai panels very highly and would go with the Hyundai quote if the price is reasonable and the solar size was suited to your requirements?

Did both companies do a site visit and offer a comprehensive design proposal?

Ive gone a head with the Hyundai.

The site is not complete yet (shed and roof not installed yet) however, the Hyundai was very good regarding invertors and doing extra research for my job.

Could not be happier.

That’s great news, :+1:

It would be great if you could post some photo’s of the finished installation for others to compare and we may even be able to use some photo’s for our articles and reviews (with your permission of course).

Well, after a long build the system is fully installed and been up and running for the past month.

Consumption is approximately 20-25 percent of total production. You can see my first full rebate below. Something is better than nothing

Not bad at all, you must be happy. As you are probably aware, you may be able to increase the amount of self-consumption further by using timers for hot water systems, dishwashers, washing machines, pool pumps and heating or cooling your home.
On a hot day, I often set my split system to run for most of the day so the house is cool when I arrive home, as opposed to cranking it when I get back once the house has heated up. You can do the same in winter as well.

You mentioned this is a hybrid system, and you have a battery installed. What capacity battery do you have?

It’s a 13kwh byd battery.

Everything I can run, does run during the day. If we are home the consumption dramatically increases with the 15.7kw ducted air conditioning plus multiple split systems in bedrooms.

Nice, the large solar array charges up the battery very quickly!

Do you have any photos of the installation you can share? Be great to see it.
