Thanks for sharing. There are so many videos out there where the solar projects are not justifiable but this one I agree has a real quick return on investment.

This is the most basic grid tied installation you will ever see. Just replaced two SMA-2500U's with a single Growatt after my SMA failed for a 4th time I was done. Been using SMA for over 21 years. At 65 pounds each are very heavy to deal with compared to the 33 pound Growatt. Using a MIN 5000TL-XH-US, it was so easy to install. SMA's have a 7 year warranty and I had to pay for 3 separate repairs over the years, what a pain to remove - pay to ship and repair and replace etc. I'm done with SMA. Growatt makes grid tie easy and cheap, and if it craps out - easy to replace.

Thanks for posting. I'm also wanting a simple, affordable grid tie system. I'll have 8x400w panels for 3.2kw. Outstanding question is Rapid Shutdown Devices (required in my location) and once those are factored in, is it still more simple and affordable than micro inverters? thanks for the input.

@smokeythebirdbrain absolutely. I would only use micro inverters if shade was a huge issue. GL

[@smokeythebirdbrain]

@@_willalexander.88 Thanks for the input. To add RSD to this inverter, I guess it would be 4x Tigo TS4-A-2F @$45/ea. And then upgrade to the MIN 3800TL-XH-US, which can communicate with the TIGO RSDs? Still fuzzy on that.

[@_willalexander.88]

@@smokeythebirdbrain no. Nothing is needed with this inverter. It shuts down when the grid goes down.

[@smokeythebirdbrain]

@@_willalexander.88 In my area, not only does the inverter need a disconnect, but you (or a fireman) also have to be able cut power generation at the module level. Just got off the phone with Growatt support: My message above is correct to meet Rapid Shutdown Requirements (NEC 690.12) Add the Tigo TS4-A-2F or TS4-A-F at the panels, and order a ..."TL-XH-US" inverter which has a built in transmitter. Also verify with the retailer that the inverter has either the Tigo or APSmart RSD installed. Apparently they make two different version to support two different sets of products. Hope this helps anyone in the future.

Great video. Two questions. Is the unit waterproof and can be installed outside like you did? Can you sell back to the grid if you have net metering with this set up?

[@_willalexander.88]

Yes it does have an IP rating. Yes if you're net metered it will push back into the grid what's over produced.

[@johngrier5949]

Can you confirm you connect the 2 120 lines to the same phase…. My manual came in Spanish, I was wanting to to just make a two ended plug and plug into an outside outlet close to my panels vs going all the way back to breaker box and adding breakers

[@_willalexander.88]

@@johngrier5949 you can wire this 120v or 240v. 240v is the preferred connection

[@bigskyproducers]

did this end up working for you? this is basically what I want to do too.

[@Arossicomputers]

How did you connect the ac plug hot 1 on L hot 2 on N and ground/Neutral to PE?

[@_willalexander.88]

@@Arossicomputers yes. Ground to PE (NOT NEUTRAL)

maxim power from solar panels 2000w?

[@charliewill4509]

so how difficult is it to get a permit and inspections done for your unit and whats the costs / process to do that?

[@_willalexander.88]

Not bad at all. You will need some structural drawings if you're mounting on the roof which is the worst part. To make sure your roof can support it. About 250$ for those. The rest is an electrical riser diagram, site plan and specs. Permit was about 200$. Contact your county for a list of what you need to obtain a permit and you need to contact your service provider to fill out some stuff with them. They do an inspection after the county permit is finalized. Good to reach out before your install to see there requirements.

[@cyumadbrosummit3534]

Been running off grid with no permit for 4 years now with 23kw of roof solar and 66kWh of recycled Tesla S/X modules. If you live in an area with frequent blackouts/ brownouts a grid tie system is worthless. WTF is the point of solar if you powerless like everyone else in an outage? Lastly you'll pay retail for power from the grid only to receive 10% of what you pay (if you're lucky) when you sell energy back.

[@_willalexander.88]

So, the point is to knock down your high $ bill and make your money back quick. I have a super inefficient rv hooked up full time that uses more power then my house. My power company is with it and we never lose power even during hurricanes. If we do, flip the main and plug in the generator, my solar will assist and let the generator idle mostly. I would not grid tie to make money, only to reduce my bill.

[@onecrazywheel]

You'd have to almost have an inverter generator to work. I years ago hooked up my propane generator 6000w and the grid tie solar system shut off due to frequency issues.

[@_willalexander.88]

@onecrazywheel going to test soon. Thanks
