Great information, thanks. I was confused at one point though as 'really' in Australian English sounds very close to 'rarely' in American or British English. At first I thought you were not recommending oversizing!
SolarEdge inverters come with standard 12 year warranty and modest upgrade to 20 and even 25 year is offered by manufacturer. You failed to mention the different rapid shutdown issues that for many is going to push towards optimizers or micros over string as most requires module level electronics for the shutdown.
Hi Finn, Good video mate, but I too thought you are saying “rarely a good option” when oversizing than really. It’s quite overt, and puts across the opposite meaning.
We are always told to put say a 6kw inverter on a 8kw system as the inverter works more efficiently when close to its limit. How much difference does this make ? At the end of the day most inverters run nowhere near the limit ? Thanks for your great videos
Nice explainations! Over here in South Africa the Deye (Fusion / Sunsynk) are the leaders, popular inverters over there are defintely high-quality. 10 year warranty is amazing.
Which type of inverter is best to tie to the Public grid system so that I could sell excess power to them and also use battery back up. A system that will not stop if the public electrical grid goes down.
Hi there, 1st let me give you my congrats on an awesome channel and very helpful content. I am about to purchase a solar system composed of 8 SOLAR Panel HYUNDAI MS10 SHINGLED 480W PREMIUM MONO, (self use for a home) with no batterires for now and with a row of panels south facing (I live in Portugal) I need some help to decide which is the best inverter for these panels. Should I go for the GOODWE GW 5048 D-ES WI-FI or the SOLIS RHI-5K-48ES-5G or do you sugest a better solution? Thank you for your help, and keep making these awesome videos. Best regards. Nuno
Hi Finn, in WA now, all new power meters allow you to monitor consumption as well as export on a 30min cycle thru your online Synergy account. Is is still worth getting a consuption monitor? Cheers
Great video... Thanks. Might want to mention the new CEC approved inverters and batteries must be able to be remotely controlled by the power companies to limit production if and when needed.
@@doublehelix109 The new standard is promoted as bringing Australia into the new energy age. The main reasons for this was negative energy prices during high residential solar production and risk of overloading the grid during low demand. Will see how this plays out as AEMO works like an energy stock exchange with second by second electricity spot prices. Turn off solar producers - price goes up .... Yay Energy companies make money .... Well just leave them off then..... Ha ha ha
Hello, where would you place Solax inverters on the chart? I’m trying to make an inverter decision for a 10 kw on-grid system for my house. I’m in Turkey and I can get the Huawei and the Solax for about the same price. My installer is recommending Solax, apparently its after-sales support is good here. What would you recommend?
I'm 100% self powered, using emphase microinverters and Tesla's power wall. Do I still need a consumption monitor as the Tesla app gives me all the info. Thanks
Can you teach me about how to consume excess generated power to heat water. I'm in Scotland and can only push 3kw to grid. I'm just learning about all this and worry about where and what to order .
@@SolarQuotes thanks for the reply. We are on Ausnet so… Single phase: 10 kW inverter limit, 5 kW export limit. Three phase: 30 kW inverter limit, 15 kW export limit.
@@Vivrichards1 Yep - so with a 10 kW inverter limit, you can have 33% more panels - 13.3 kW :) See here: www.solarquotes.com.au/blog/oversizing-solar-arrays/
Great video Finn. Just be very careful with Sungrow units ( and others that use cheap switching ) . As with cheaper inverters they use MOSFET DC to AC conversion , if you have children in the house they will hear an ear piecing noise at 16khz on inductive loads like appliances with motors, smoke alarms and desktop PC.s IT becomes super annoying. Also note that persistent a VLF signal can degrade components over time. Sungrow sadly ducked and weaved for months all the time knowing the issue, swapped out inverters promised upgrades and just waisted our time. In the end they offered nothing. Our fix was paying more for a Fronius unit these use IGBT switching at 20khz and employ much better outbound filtering. So the old adage you get what you pay for is 100% correct. Our installer was excellent through process and didn't charge for all changes apart from the inverter upgrade. Fronius were excellent help and there unit is built so much better with all connections internal and no silly wifi dongle that can be stolen or broken easily. I know there are a stack of Sungrow units out there running with no issue , but there is a clear difference in quality.
Yes - they are much better than they used to be. but I'm not sold on them yet. They were so bad back in the day they are going to have to come a long way to win me over!
@@SolarQuotes I've had a think, is the inverter a complete metal box? if it is it probably is EMP proof. I guess people in part want Solar in case the grid goes down and the theory is that an EMP wave from the sun or a nuclear explosion would wipe every unprotected micro chip in it's path.
I just bought 5 brand new DAH panels (410w each) so just over 2 kw total . I want to charge my EV and other loads when not charging EV. Also will be adding battery storage of some sort . Do I need a hybrid inverter ?.
Am I totally nuts, or at 8:14 did you just: 1 describe what inverter oversizing is, 2 say it rarely makes sense, and then, 3 give give two or three examples of why it makes sense?
I am a bit confused now!! About 10 months ago, you posted this video ruclips.net/video/WFpOc3UsvJg/видео.html which is about a test in SA comparing string and micro inverters. With shading, the string inverters had very little to no loss in energy output. And here, you are telling the same “porky pies” about the benefits of micro inverters.
Oversizing is always a good idea as you'll never reach more than 80% total performance if you're lucky, you'll never peak out the inverter otherwise; might as well just buy a smaller inverter then for cheaper if you don't want more panels. This video is bullshit. At 3:30 you explain why it makes economical sense installation wise, and then argue it's therefore not better bang for buck, a statement so void of logic I wonder how you survived in this field till now.
Would you have any recommendations for a 6kw wind inverter replacement?
Great information, thanks. I was confused at one point though as 'really' in Australian English sounds very close to 'rarely' in American or British English. At first I thought you were not recommending oversizing!

superb video! I am just curious if pure sine wave is a standard for any modern invertor by famous brands?
You missed Growatt. Seems you don't know the Australian market that well.
Another great video Finn with easy to understand summary of the key things to look out for with inverters. Keep up the great work :)
Thank you
@@SolarQuotes finn another company thats been suggested is Fox ess inverter and battery have you heard good things about this company?

Thanks for the videos
My only thought is the gap to micro inverters is more like 50% more
Are you saying rarely or really?
Relating to panel oversizing
Really :)
nice video to explain how to use mirco solar inverter,thanks
Surprised Victron wasn’t on your list

@@TheAidanVogt Only a matter of time... WA, SA is already mandatory. Power companies are pushing for yearly inspections to get everyone to comply.

I'm 100% self powered, using emphase microinverters and Tesla's power wall.
Do I still need a consumption monitor as the Tesla app gives me all the info. Thanks
No you don't. Great point. The Tesla Powerwall has its own consumption monitor via the tesla app.
Why do you have 2 solar analytics monitoring devices?!
And is a Hybrid alway the best one 2 get ???
Can you teach me about how to consume excess generated power to heat water. I'm in Scotland and can only push 3kw to grid.

Look into "PV Diverters"
Thanks for the video. Do you need 3 phase power for a system larger than 6.6 kw?
Hi Viv - It depends on your DNSP: www.solarquotes.com.au/grid-connection/
Many allow 13.3kW on a single phase, as long as it's export limited to 5kW.
@@SolarQuotes thanks for the reply.

Want to do a blog post on your experience?
Do you know if Solis have the same system?
What about Growatt? Are they better nowadays?
Yes - they are much better than they used to be. but I'm not sold on them yet. They were so bad back in the day they are going to have to come a long way to win me over!
Would a solar system function after an EMP wave?
No idea! Sorry.

Ok can someone tell me if a string inverter with no shade issues is as good as a microinverter when you have two strings that have different aspects?
I would expect difference in performance to be totally marginal :)
@@SolarQuotes thank you, I'm looking at buying a 8kw Solis inverter with 9.9kw (450w Risen panels) Half with an aspect of NE and the other NW.
