I like the Growatt too. Have you had ANY interaction with Signature Solar. Their negative attitude towards their customers concerning their product before the purchase leads me to believe they would be a disaster to work with after a $20,000.00 purchase. ALL I can imagine them saying after my...

I upgraded my 4 growatt 5k es inverters with SS's help and it updated perfectly. Did not fix my problem of 3 inverters not starting with PV power, but did upgrade the max amps from 18a to 22amps.

26% for 2022, 22% for 2023 taxes and after that I believe it is 10% for professional installers only. Unless it gets changed or extended.

FYI Taxes due is misleading. Tax liability is what it is. You can get prepaid payments or paycheck withholdings refunded. Other than that Tim is right on.

I have 4 Growatt 5000 ES and the 4th one does that. Do you think a software update will fix it?

This is what I ended up doing.

FYI 6/12 pitch is 26.57 degrees. 12/12 pitch is 45 degrees

What is being said on that thread has gone in circles so many times I can't even figure out what is being said that works and what doesn't work. Unless YOU plan to personally fix the problem for the followers of that thread then a final decision of what works needs to be made and simplified so...

Don't most people that want an off grid converter that is grid tied because they want PV first then battery then grid then generator. Doesn't that cover all the bases. Power no matter what. I'm in the planning process and ready to purchase 30 - 395 watt panels. 2 x 6s2p and 1 x 3s2p. Each of the...

I'm not an electrician. It is my understanding that SPF5000 ES has a 450 VOC definite maximum and 18 amp cut off. Above 18Amps would just be clipped and no harm to the inverter, but go over 450 volts and your inverter dies. At 49.5 VOC per panel your maximum series would be 9 panels, however...

Buying it now and getting 26% paid by tax write off is better than waiting for price increases or not available and no write off later.

With the growatt SPF 5000 ES L=Line 1, G=Ground and N=Line 2. L1 & L2 are 120 volts each. No neutral is connected to the growatt inverter at AC in or AC out. The neutral is supplied to the neutral bar in the breaker box by the split phase transformer.

Thanks for the quick replies. I left out the GW paralleling and the power sharing wire connections because David Poz has a great you-tube showing how easy it is and I didn't want to clutter the diagram. The welder and Hot water are for future use and not used at all. When I built the house I put...

I've talked to my insurance agent and he didn't have a problem adding it to my policy. He said if it is not already covered in outside structures, it would only add about $10 a month. I'll be getting more detail from him soon. Also, I am not totally off grid. I'll be using an off grid inverter...

Free labor and when your done you know every part of your systm and what it does. Good luck and enjoy the build. I sure did.

Just to help you understand, the 15Kw never goes through the transformer. The transformer only balances the load between the two phases. A 240v appliance pulls equal amps from each 120v leg, but if you are using 3-120v from the same phase the transformer needs to balance the two phases . The...

Apparently, with Emphase inverters your going grid tied with a net-meter. you should look into using an off grid converter that is grid tied and zero feed back to utility. No utility paperwork and in some cases, no permits and the power doesn't go out when the utility is down. Check out...

The program I use is a part of "Punch, Home Design and Landscape Pro" called "detail", it works similar to a Generac cadd program I used for years. I've had it for about 7 years and I used it (The 3D Part) to design my house I built 6 years ago. I went to vertical panels for several reasons. 1...

I saw on another thread it does work just like yours does.

yes

Does anybody know what Signature Solar in Texas has to say about this. I just got a quote for a 48v SPF 5000 ES off grid Inverter for $899.00 plus $399.00 for the Transformer Kit and it's my understanding that the load will pull first from PV and charge the battery with extra or pull from the...

I would run 4s1p to each inverter and use 10awg wires to run from panels to inverters. since you plan to put in more panels you could do up to 6s2p per inverter (24 panels) with no additional wiring. Makes it easy to add panels later and not have to run new wires to the inverters every time. top...

I have 11.8Kw of solar panels and I get between 1 and 2 Kw per hour production on cloudy days. As long as it is light you will get some production.

Is Anyone currently using 1 or more SPF Growatt 5000 ES, or know anyone (that can be contacted for comments) that is already using this system that works the way it is advertised to work? What I mean is, it is connected to their house and it powers the complete house with just PV power during a...

If that is a 48v Growatt I believe you need 2 more batteries in series to give you 48v and 200A. 9600 watts of storage.

That makes it look almost to simple. Am I correct to say the Grid could connect between the Generator and the charge controller with a transfer switch. Also, your Charge controller could be the SPF Growatt 5000 ES with a Transformer.

26% tax credit this year for DIYer or professional install. Only stipulations are must be new (not used) and you can't count DIY personal labor.

My generator and the grid are separated with an Auto transfer switch, so they would never work together. The SPF growatt 5000 ES advertises quote, "The 5000ES can work with or without batteries and even pair with the Utility if solar is not enough to power a load". What I'm Interested in is the...

"The Growatt SPF 5000W ES is the all-in-one inverter/charger you need to take control of your energy bill. The 5000ES can work without batteries and even pair with the Utility if solar is not enough to power a load. Can Stack 6 Units! (30kW of Capacity) This backup power, self consumption...

CCat, Why do you have 2 midpoint transformers. One is all that is needed to split the 240v into two 120v. David Poz has a good you-tube explaining this. OR am I missing something. I'm new to this, but trying to learn.
