I have a concern on microinverters on putting such a critical potentially sensitive thing on my roof. In particular I live in Tucson and that much heat hitting the inverters would be cause for concern. Potentially increased Failure rate in that condition and maintenance is all done on the roof (if you're lucky - you know exactly which panel needs attention). I guess with optimizer - less of the brain is on the roof exposed to direct sunlight - the inverter is in the garage. A panel can function potentially without an optimizer (bypass diodes on panels should handle a big chuck of the shading impacts if you needed to temporarily remove an optimizer I guess).
There are certainly always concerns any time electronics are exposed to heat. Micro-inverter manufacturers take this into account when they design their products, but there is certainly potential for some failures. As for optimizers, you would not be able to remove an optimizer and have the module continue to function. In an optimizer system, the module must be connected to a functioning optimizer for it to connect to the inverter.
@@thesolarenergychannel Thanks for the info. The other part that concerns me about micro inverters is the increasing focus on battery and EV charging. With DC coupled you should be able to charge those directly from the panels . More efficient but also potentially faster and less of a need to have to touch Main house panels
You left out a few things/features. Controllable export, like here in CA, I don't get the benefit of "Net" as we are on NEM3.0, so being able to set up as Zero Export is desirable to me to ensure my batteries are fully charge by the TOU 4pm - 10pm peak cost. Also, it wasn't discussed for your audience, but which will perform in a grid-down scenario and which don't. I think that's an important distinction. We use an EG4 15Kpv, and EG4 wasn't discussed, but ti is a CA certified hybrid inverter.
I've spent all day trying to learn all these details. As a Californian, you've got my attention. Does getting a battery backup system negate some of the concerns you bring up? We're looking at the Franklin WH for all the reasons you bring up.
@@rilijn Franklin is a good call, we have 60Kwh with no export, but that may be overkill for you. A 15Kwh to just try to cover the 4pm - 10pm Time Of Use rate hike is the most cost effective strategy.
What about these Inverter,1200W Micro WVC-1200 and WVC-2400 inverters? I have one of each of them, both will only produce 25 percent of the input power. I have measured the input Voltage and amp on one panel, to be 8 amp at 40 voltage and both the WVC 1200 and 2400 inverter only produce 80 watts on the output. The 240 volt connection option does not work. Is there another grid tire inverter like this that actually work?
growatt, casi nunca fabrica sus inversores, algunos de esos inversores los fabrican terceros, como la mayoría de los fabricantes, y ese tercero es VOLTRONIC
You mentioned the manufacture, where is the manufacture located??? You state that it's all manufactured in the United States. Are you promising that there is no Chinese product in the unit 100%?? So there is no Chinese capacitors, relays...... SO, No Chinese product with 100% guarantee? I would like to see where the capacitors are made and the bridge rectifiers... Thank you for being so honest with your review. Is everything made in the US???
Enphase is manufacturing their microinverters in the US. We were at their factory in Arlington Texas a few weeks ago. That doesn't mean that all the components of a microinverter are made in the US.
@@thesolarenergychannel you say manufacture, but don't you mean assemble? General Motors is not a manufacturing plant. There are assembly plant. At least when General Motors buys the electrical component from China they don't state, it was made in the US, they just state that their car has been assembled in the US. So now, can you reply honestly, how many parts in each assembly has been manufactured in the United States?? And which ones?? Donald Trump wants to know!
@@thesolarenergychannel Uh, you guys are meant to be electricians, right? I've never seen more math in a trade industry than in the electrical trade. BTW, SMA only build their products in Germany and haven't made anything in China since 2018. They source some components from Europe. Also, a very significant portion of SMA's historical market has been Off-Grid with the Sunny Island forming the core of that infrastructure. Regarding micro-inverters and panel optimisers, which conceptually do the same thing of panel-level processing rather than string-level processing, there is no need to use panel optimisation for installations that have clear exposure and relatively simple layouts of panel arrays. SMA even have anti-shade optimisation tech which will take care of a lot of shading issues. When to use panel optimisers? When shading is complex and intrusive across different parts of your arrays in different areas and at different times, and when a large roof is fiddly, fussy and complex. The last use case really comes down to the installer and their preference. The geek factor is cool but there are plenty of other features to geek out on, such as: - sub-10ms switchover of an entire house load from grid to pv/battery during a failure (true UPS) - dynamic balancing of energy supply to single phase loads across a 3-phase system - hybrid inverters that can handle all panels being DC Coupled, and - being capable of simultaneously supply grid, loads and battery without drawing from the battery in a DC Coupled topology The downside to SMA right now? They don't yet have 15, 20 and 25 kw 3-phase Hybrids.
I've had 3 SolarEdge inverter's breakdown in the first 6 years. It's costly to have an electrician come out and replace each one. Thanks solar edge for wasting a lot of production time and money! Solar edge sucks!
That's unfortunate. This is one of the reasons why it's valuable to work with an installation company that has a workmanship warranty that would cover labor costs and production lost in the scenario you described.
@@thesolarenergychannel The thumbnail I see shows inverters on the left behind a green check and inverters on the right behind a red X. Not sure how else to interpret that.

With micro inverters you’d be subject to more clipping potentially, and more DC -> AC -> DC conversion limited

WVCs are junk. Low quality components, low efficiency, high heat.

With age comes wisdom.
Solar energy is a clean and renewable resource, so using a solar inverter helps to reduce your carbon footprint.
An inverter is a necessary component for solar production.

So, the thumbnail was just clickbait? I didn’t see a single mention of an inverter to stay away from.
The title and thumbnail text don't suggest that we mention brands to avoid. Clickbait is never our intention.

@@LTVoyagerit’s absolutely clickbait. Alluring the viewer that they will receive specific information on brands then not delivering that is deceitful.
