If I install a 10Kw inverter with 5kw panels would that work ok ? I want to be ready for future needs...

1. No information on how to protect your panels against hail was provided. This renders the video title misleading. 2. The guy's Aussie accent was so thick I had trouble understanding him at times.

Well that was a pointless video

do i want to go over on the amps or the volts?

The Government, Power companies and your electricity supplier are all out to screw the people with solar, month by month the system and plans change, you don't get more you get less, it's at a stage where unless you get a system with a minimum 10 kw battery you will be paying for your power

Irritating music. The content is the MESSAGE Music is a messy intrusion

We could add cooler and heater to help temperature efficient stabilized in all temperature so panels always operate at highest efficient if we keep it always st 25 Celsius

Anyone tried heavy gauge framed steel mesh on a standoff above each panel? Would be expensive and heavy but might work.

Hello, first of all great content. I have 36kw of solar panels, ground installation. It must be limited on 23kw cause that will be max grid will accept. I 'm in dillema of choosing inverter between 25kw SMA or some 30 or 33kw Huawei. I'm closer with SMA cause they are more premium brand but i have concern about power. They do not offer anything between 25 and 50.

Interesting. I have seen recommendations to have slightly more panels than the inverter capacity. Simply, that it will be vary rare (not possible) to hit the panel capacity and the inverters will simply cap the feed. Perhaps, this doesn't work in Australia since 10 kW of panels may actually generate 10 kW due to high intense sun?

I like to go 30% over on panels to inverter if theres plenty of room for the extra panels!

Okay, How do we protect them? Hello?

Will there be risk on a sunny day when 120% is actually absorbed by the solar panel? My inverter has a built in solar charge controller.

Oversizing or undersizing(supercharged) inverter? The only time that oversizing the inverter is a good idea is when the customer plans to add capacity in the future.

Oversize everything except voltage

It is very bad idea to put annoying music in the background!

Can I put 20kwh on a 5kwh inverter? If the voltage is lower than the maximum allowed

Informative & easy to follow advice, thanks Sam.

Unfortuntely, if your panels get damaged in a hail storm then the manufacturer most likely will not cover the damage and your installer is not liable. You basically have to make a claim through insurance and face higher future premiums.

Hi guys My solar installers have done the opposite of this They've installed a 10kw 3 phase sungrow inverter And 24 370watt Canadian split cell panels totalling 8800 Watts What's the best way to sorry this out? Please advise it will be greatly appreciated

Your title is misleading. You didn’t answer how to protect it from bigger hail larger than 25 mm.

It would of been nice if he stated this explanation is for a grid tie inverter, because none of it made sense if it isn't. for example, solar panels supply a charge controller the charge controller supplies DC to a battery the inverter is then connected to that battery to supply AC to appliances, in a battery system the inverter does not connect to panels it connects to a battery.

We get BIG hail here in the US Midwest. It ruins cars, breaks windows, dents siding and damaged roofs.

I didn't catch the part where he protect3d it from hail

This is not called inverter oversizing, it's pv oversizing.

What size inverter do I need for a 9.6kW solar system? I need the maximum performance.

I prefer to lay spread-eagle, face up, on top of my solar array while screaming "Is that all you got!!!???" In all seriousness, solar installer here, most small hail won't break a panel. If the hail is big enough to break a panel, it's big enough to kill you and your roof is for sure ruined. We've done a lot of de-installs where the roof was trashed and the panels didn't need to be replaced. They're suprisingly strong.

And even the major power loss due to partial shade on a string inverter is busted/outdated

Thanks for the good video, I do still have a question that is in reverse of this video (undersizing solar inverter?), let's say I want to think about the future and get a 3kw solar inverter but I only add 500 watt solar panels for example. Would this cause problems with the efficiency the system is working on?

Pray over it.

Music makes hard to understand

Good vid! But..I have a silly doubt... I understand . feed in system and I the blackout (after sunset till sunshine). My question is; What will happen when the power grid is completely off due to a earthquake.? How the inverter functions when at 11 am clear skies,? I mean, in case the Nation's power grid isn't accepting "feed in" due to a natural disaster how the inverter will behave?

Oh come on!!!!!!!!!!!! Do you seriously not know the difference between "Energy" and "Power"? redrok

Sound advice

Hello, If on my inverter (3.5kva) is listed 5000 maximum imput power, can I put more than 5000watts pv array or it will damage the inverter? Thank you

This is exactly what I was looking for. It goes based on actual cell temp not ambient. So if I measure the temp of the solar cells while they are in the sun I should have a good ballpark to calculate. Thank you.

Which temperature that affect the solar panel, is it the temperature of the panel surface, or is it the air temperature arround the solar panel ?

Short, sweet and clear description of oversizing.

There is no video it's only audio is that how it's supposed to be

If oversizing isnt dangerous why do Fronius and MPPSOLAR quote PV watt limits and Growatt too! A 5KW Fronius says 7500W is the PV Watt limit, MPP depends on the units but some are 4500W. As the solar panels don't push the inverter, but pulls power out of the panels thus the MPPT will adjust itself to get the most power out; so if someone had 9000W of panels and the sun is in ideal position to allow 8-9KW to be delivered to the inverter, MPPT would want to get the most amps/volts thus power out of the panels? Seems there is a rule of thumb of 133% oversizing but not more????

Thanks

Yep - good solid advice here.

Good 👍 video

Great!

I wonder if you could harvest the heat out of them and use for hot showers and junk.

"Did you know there are three main types of Inverters?" A power optimiser is not a type of inverter

Music is too loud and voice is to low.

Sorry mate but your background music is almost as loud as you are.

May I install some water spray nozzles on the PV as a cooling system to keep the efficiency? thx

hi'Mate ,do you also teach the math of this? ,' cause im looking for someone to explain a few thing to me
