Thanks for this comparison. Basically I recently installed Hoymiles-1800W micro inverter . I was able to decrease the temperature from 46degrees to 29 degrees by adding 4 12V fan. For the internet monitoring, I bough a simple DTU key 35 euros to track it.

I like my Fronius "ecosystem" but I wonder does it really support only BYD and LG batteries?

I have been using three phase Zappi 2 for the last 3 years.. I generate enough solar in Sydney summer to charge my Tesla Model 3 long range on excess solar at 11kW.. Never had over-heating issues.. My Zappi is in the garage..

No having problem sorry went through the this a couple of time with out any luck

I have used products from Solplanet, and I've had a very good experience with them. Solplanet's products are of good quality and are also easily affordable at lower prices. So, please do not spread fake news of negetive reviews about Solplanet's products. 👍

Interesting but a bit misleading. Most people aren’t so much worried about the output of one panel when it is slightly shaded. They’re worried about the impact of a whole panel or more being shaded impacting production of other panels in the string. For example a tree or building shading half of your string as the sun moves. That’s the comparison we need…

If you are talking about charging your EV, one really needs a very big batteries to charge it overnight. Or need to charge the EV during day time with big power of solar panels. I am installing a 25kw+ panels on my roof for that reason.

Thank you very much for your explanation.

Love my Zappi charger! The one you show is the v2, the new v2.1 is very different internally but does still have the overheating issue, they de-rate when the internal temperature gets over 65 degrees, Due to the very good export tariffs available here in the UK (double what I pay overnight) , I no longer use my Zappi during the day, it only charges overnight so never has issues with being too hot, probably good for longevity too.

I have GEN24 for 2 years, the first year without problems, the second every two or three months an error appears (the manufacturer does not know what the error is) and a problem with WiFi as well. With a new modem, the distance is even 5 m. Reset unit everything returns to normal. And adding a 7.1KW battery for 12+ thousand is a rip-off in broad daylight. Apart from that, it is a good inverter, maybe it just happened to me, who knows?🤣

Hi Mark, if i have single phase home and a Powerwall 2, will the solar panels keep charging the powerwall during an outage? Thank you...

It’s not free you have to pay for the system and installation but when installed and operating your power bill should be reduced depending on what system you install the nil upfront cost is incorrect

Hello! Thank you for your interesting videos! I have a question for you! The situation is this: I live in Ukraine and before the war with Russia I installed a 10 kW station with a Gen 24 Plus inverter and a 5 kW BYD battery! Now Russia is constantly hitting the Ukrainian energy system, destroying our substations! In winter, there is little sun, the city grid stations are destroyed and there is no electricity from them for months, it is impossible to charge the battery! There is only a 5 kW gasoline generator! How can I safely recharge the BYD battery from this gasoline generator? Thanks in advance for your help!

Great vid. Just shot you a quote request on your website. Thanks!

Sigenergy is making noise lately. It will be great to hear your thoughts on Sigenergy...

Perhaps a better solution would be for Myenergi to use a decent contactor. It shouldn't run hot.

Thanks Mark. Interesting as well as informative. It'll be interesting to see how BYD batteries compare to the new Tesla Powerwall3.

We have a Zappi and it's great. We have single phase, all that high current stuff doesn't apply. We have 4kw of solar and we leave the Zappi to harvest all it can and a couple of kw is the best it usually runs at. It needs no app. It has a panel. It is not connected to the internet. How do those app controlled charge points talk to a phone? Do they have a sim card? Or am supposed to rewire my house to get internet into the garage? No the wifi signal does not reach.. No, I am not going to park my car in the living room just to get wifi

2:21 Today panels made of the 6 sections but not 3 and pais go in parallel. I wonder if today this problem described is still relevant for the panels consisting of the 6 sections?

It is not better! It is junk just because design was made so poor. I'm speaking about 3phase Fronius. It requires exactly 3 phases, while in theory it could work only having one phase and the rest could be taken from solar if not enough or solar not stable. Why on earth you would want do an expensive 3 phase upgrade when you actually need less dependence on the grid? If it can work full backup when no grid power then I have a question why on earth I would need to connect it to all 3 phases? Why it can't just work of one phase? This makes no sense as upgrade to 3 phases cost more then the cost of the 3 phase inverter 10kWh. This is so stupid. I was thinking I found a good one, but this was a show stopper for me and I have to start looking for something else. What a disappointment.

I currently run a standard hot water system under 200L on an off grid system. It's inefficient. I have an older best pump system that needs a new thermostat. I'll be installing that soon. Also upgrading to 50kw of battery and 20kw solar. I live in town and have a grid connect system as well which will just take care of solar feed in and back up if required. I do it too me self reliant and independent of government and the BS or there. Not for climate change or net zero which is a scam. Be free.. Not a compliant slave.

How about a roof mounted solar hot water system with a heat pump?

Welp in my case it shows no network available but the network connection is for sure there..

I have used Solplanet products and had a very good experience with their quality. I’ve had a fantastic experience with Solplanet products. Their quality is exceptional, and I highly recommend them for anyone looking for reliable and efficient solutions. Please don't spread fake bad reviews about solplanet products. 👍

Hi, I have a Tesla MY and I am not sure if I should get a Tesla or a different home charger. I have been looking at the Zappi, Ohme Pro and BG Sync. I do not have solar panels installed, but might be thinking at them in the future. What would you recommend?

Why are you putting an element hot water system at $3300? $1150 will buy a Thermann element hot water system at Reece plumbing with wifi control of temperature and heating times which suits solar. Also, the 1.6kw heater in the heat pump is tiny at 1.6kw in hybrid systems. I’m trying to imagine using a smaller element than found in a kettle to heat 160 litres, or 160 kettles. It would take hours.

Why are you putting an element hot water system at $3300? $1150 will buy a Thermann element hot water system at Reece plumbing with wifi control of temperature and heating times which suits solar. It also has a component that separates hot and cold water.

Any idea if the latest update fixed the issue? As if July 2024?

Thanks so much. My installer is no longer in business and being fairly tech savvy I knew it couldn’t be that hard to change. When I cam across your tutorial. Brilliantly done and I’m now up and running. The only thing I can’t see is my past 3.5 weeks data, has that been lost ??

That's interesting. However, the Zappi looks like it can be upgraded or repaired cheaply. The other units would have to be replaced if they become faulty. I still think all the intelligent sockets are a rip off, it's not at Charger, just a socket, yet they are asking hundreds of pounds for them.

Is this something you install later on to an existing fronius system or do I need to go back to the person who installed the system? (Brisbane based)

Great work!

Could you explain in more detail how MPPTs in a string inverter could still optimize leaving behind one fully shaded module in the string? If one panel in a string is fully shaded, naturally the entire string is affected since they are all connected in series and there is no way an MPPT in a string inverter can still perform to get the juice out of the remaining unshaded modules. Your response is much appreciated.

I have an electric tank that enters the heatpump tank then to house taps , I was going to swap it round and get heatpump to run first but had a thought to leave it as let the electric do most of the work so at least the pump will last longer

Is there any evidence of ethical issues regarding BYD or is this just another case of Western China bashing. It is heart braking to witness a seemingly sane person bring out an issue out of nowhere and attempt to make it a big issue that a consumer should look into before purchasing a product.

HI Mark. When we looked at getting a home battery we were told we’d have to buy an inverter for each powerwall vs the BYD that we could expand with extra modules without having to get any more inverters. For us that was a deal breaker and we went with BYD. I noticed this didn’t come up on your video. Were we given incorrect advice?

Subtitles might be via AI Bot which doesn't understand Aussie well. I have Longi Hi MO 5m LR5-72HPH 555 W panels. Here searching if they have internal bypass diodes (spec sheet doesn't mention). I wonder since I see a great increase in power output when one panel in a string of 7 comes out of shade at 10 am in July (U.S.). If diodes, they should just bypass the single shaded panel, not limit the whole string. If no diodes, I need external optimizers to get more power in the morning. (Can't trim the neighbor's tree). No shading in Winter. The Summer sun rises and sets ~45 deg north of East-West on June 21 at 38.6 deg latitude.

Thank you so much for your high level of expertise, integrity and standards. You are one of the only CZcamsrs I trust to learn about technical matters on PV. You are like Elon Musk you try to understand things from first principles without listening to any opinions and this is precious.

Hi Mark. I have changed my internet provider. I have done what you said in your video. I get as far as choosing the Fronius from the Settings but when I enter 12345678 I just get the message The web page is not available. Any suggestions?

Great work Jason! Love what you've brought to the design/consultancy service for MC Electrical... and make sure Mark has his morning coffee before going in front of the cameras.

Trying the hoymiles for the house but cheating a bit. Have a central location for my inverters so access is better and can ensure good ventilation and some shading. Got to do a bit more research but looking at the 1600 watt micro in with 3 of them running in series.

Would have been better if you included instant gas - not tank - and homes with no solar .

My house faces north in Brisbane. What about a solar hot water system? How does that stack up overall? My 16 old Solar Hot water system has died.

good debate what a shame Istore brand heat pumps are rubbish

i have tried to use wps it didnt work then i tried going thru with the iphone when you get to put in the password for the inverter it says not authenticated.so i dont know why it does this .i called the people who put it in and they got it connected,but surely there must be something simpler.or fronius can sort there connection

So much has changed since then. With microinverters and cheaper panels , optimal isn’t essential. On my roof, which has areas pointing in all different directions, none of them perfect, I have panels everywhere. Each group provides power at different times.

I’m always surprised when the openevse chargers are not compared

Thanks Mark, an informative video. I actually found this after doing a search as one of the sales people giving me a quote mentioned that the best solution was to use solaredge optimisers because the shading on my roof would void the warranty of the panels. I checked the warranty doco, usual manual doco and can't find any mention of shading clauses. Am thinking the manufacturers have since removed these clauses, but the sales guys haven't caught up yet. Good that you have picked up on this 2 years ago and brought it to the surface.

Why don’t you like Solaredge?
