I did this in early 2017. Please post all critiques. Compliments not necessary. This is in Southern CA. the ground slopes both east to west and north to south. The ground is packed hard clay and granite with rocks and a crusty top of 2-4 inches. Very hard to work with to engineer.

Folks, you cannot call Deye and ask them to private label an inverter for you in the USA. that may be limited to SolArk. I believe you can call Solis, Growatt, Luxpower and some others and they will private label you an inverter. So maybe the forum should have a design your ideal inverter...

The price for lithium batteries is not translating to savings for the consumer. At my local Kia dealership, they are very well stocked with 72k - 80k EV9 suv's. That's a lot of money for a Kia. That's in So Cal. Here, while the gas prices are still high, the utilities are relentless in...

Well, I have been using Outback Power Flexmax controllers for the past 7 years. They work 24x7 and not a single hiccup. They are built tough and for the long haul. But here is what really counts: MPPT is a computer software program in the firmware of the controller. The task of the program...

I just replaced Trojan FLA bank with LFP. Gone is my distilled water. Gone is my specific gravity tester. Gone is my use of Kopr Kote on the terminals. Gone is my wire brush to clean off acid build-up. Gone is my checking battery acid levels monthly. Gone is my venting of hydrogen from the boil...

REPT in the Ebox, CATL in the V5. This probably accounts for the different dimensions. Both are high quality batteries, considered top line in China. https://chinarept.com/en/ What I like so far about the Pytes is that the company has a good USA presence, online documents, downloads...

Guys, relax. The solution is very simple. First, forget about NEM in CA. There is reliable sunshine for self consumption. PV systems for both roof top and ground mount are not required by law to be connected to the grid. Build out your own off grid system with a liquid cooled generator...

I think his rates are too low to "make money with a battery". Here in So Cal, out peak summer rates are over $1 per kW. That's how you make money with a battery. Even a propane burning or diesel burning generator is cheaper.

Question: You said your electric bill is $1,848 and you use about 14,739 kW annually. This figures out $0.1254 per kWh. Solar will not save you any money. The only benefit you receive from solar is production of clean electricity which others including the utility are doing on your behalf...

I think you are way off base on your thinking and I completely disagree with your comments. "Environmentalists" ARE sensitive to nature and living things. Environmentalists don't have the money nor giant corporate backing to mine lithium in the Salton Sea or create large solar and wind...

When I installed my system in 2016, I hired a solar engineer who was licensed. That person came out to the property, reviewed with me the system design I had in mind and referred me to a master electrician for further consultation and design. The electrician came to the property and reviewed...

From PV magazine: "The California Energy Commission (CEC) has issued flexible demand standards for swimming pool controls. Starting in September 2025, pool controls sold in the state must default to operating pool equipment when electricity prices and greenhouse gas emissions are low. Both...

In California, where the ground is often hard and may have granite or clay, the typical ground mount is using 12 inch concrete round casting tubes, 36 inches into the ground. Posts are schedule 40 2 inch galvanized pipe. The pipe portion in contact with the concrete is wrapped in 10 ml PVC...

Tin plating is optional since solder itself is 60% tin. Plus, I am mechanically crimping, not soldering. I have used both tin plated and non tin plated over the past 7 years with flooded lead acid batteries. The joints all held without problems. For this application in a dry environment in a...

I installed 3 arrays using Prosolar rails. They are aluminum. they are rigid and last, but very difficult to work with and take extra time to install. In order to fasten the rails to the cross bars, you have to line up the rail and then mark a place on the rail where you will drill 2 holes so...

This is my free advice: We start with 2 rows of panels, 10 panels connected in series. At the last PV + and PV- connection in a series, you make a 10 awg cable using PV wire and place a male MC4 on one end leaving the other end bare stripped wire. Then make a second cable using 10 awg PV wire...

Unfortunately, just like Covid, these rules formulated, tested and passed will spread to all states with utility operators as they lobby the state legislature. Just wait, your turn is coming.

Will, the CHNT inverter you have shown in this thread is very similar to the Growatt using the same naming convention. It is also similar to the Solis S6. These new high voltage inverters pretty much have done away with a display panel in favor of a series of status LED's. This is supposedly...

You're a funny guy. I ran a 44,000 watt FLA battery bank through these buss bars. All connected with 4/0 wire and copper lugs. 4 strings at 48 volts nominal and 1 connection to the inverter. Total amperage was 900 amps. These buss bars never even got above room temperature. You must not...

If you want to be free from all snooping except maybe satellite imagery, then simply install flooded lead acid batteries. With care they last 10 years. Attach to a good MPPT charge controller like Outback Power or Midnite Solar and connect to your inverter. Nobody will be the wiser. Just...

I used Hollaender connectors when I built our 2 inch galvanized steel schedule 40 pipe based ground arrays. And you get a rock solid array. The procedure is simple: dig a hole, insert your vertical pipe, pour the concrete and plumb the pipe. Do this for the 4 corners of the array. next, run...

Do you have any customers already selling your products in the USA and if the answer is yes, then under what name brand?

I am going to say this again over and over on this web site. If you want a steel and extremely strong ground mount that will last for many, many years then do this: I have added some photos below. One or 2 persons can complete this construction with all easily found tools and materials. Plan...

Your questions indicate that you are very new and do not yet have a high level understanding of how solar panels actually work. In cloudy conditions, they will produce electricity. In sunny colder conditions in the 20-30's they will produce the most electricity. On a dark, raining overcast...

Cited article on www.climate.nasa.gov: "Ancient air bubbles trapped in ice enable us to step back in time and see what Earth's atmosphere, and climate, were like in the distant past. They tell us that levels of carbon dioxide (CO2) in the atmosphere are higher than they have been at any time in...

Non Floridians attention: Most persons building in Florida who have money build with solid concrete steel reinforced foundations using a mix of steel girders, poured concrete and steel walls, concrete and steel columns. the trusses may be steel or engineered wood. they may be covered with...

10 years required in California for CEC and grid tie.

Laughing. Almost $1 per kWh in San Diego now from 4-9 PM.

I understand what you are saying. My PCIA charge from my utility is about $0.045 per kW added onto my community power costs each month. The entire utility bill is like getting one of those smelly sticky substances that won't wash off on your hands. I hate it.

NEM 3.0 in California is based on several factors, all of which pay homage to special interest groups: Poor people cannot afford solar so they should get supplements to reduce their electric bills. Native Americans on reservations cannot afford solar so they should get supplements to reduce...
