Interesting!

My family would be more at a risk of leaving had I wasted money on a system that over produces 8 months of the year just to brag that my utility bill is near zero during a few hot months. IMNSHO

I checked out the battery and what I found weird is the lifespan is “5-10 years”. What does that mean? Eg4 power pro by contrast has a 8000 charge cycle time. That means if you charge it every day it’s lifespan is 20 years. what am I missing on the Amp Inc battery you posted? Am I reading this...

Just for clarity (I am a noobie) can you get power out of the gen input, and through your regular pv input at the same time? Is the setting gen peak shaving?

Got it. I have the same inverter and was wondering about ways to use the gen input/output. Currently my current panel array is only 6k but looking to upgrade to more panels and more batteries.

Are you AC coupling through the gen input or through the grid? What is the benefit you were looking for in AC coupling?

Very impressive!

While I did work with an installer, for the most part he just did the labor and I bought the parts.The cost of large gauge wiring in particular surprised me at how expensive it was!

That seems like a great deal!

Yeah, I agree the hot water heaters are a big savings!

Sub $1000 per 5kwh would be nice.

The panels aren’t really what I am waiting to drop, but instead the batteries. My interconnection agreement is a topic for another post. It is a saga that has been on going since last October. I agree, summer will be a different story. I will try and update this post after a couple hot months!

Not my intention, just a fat finger typing mistake!

I agree! I do want to upgrade, it just boils down to cost!

Ah! Good catch!!! I fixed it, now it is a 2900 sqft!

After witnessing power grid failures in Texas and California, and because I live in a rural area and on a well, I wanted to design a system to run our basics should we suffer a similar fate. We define the basics (critical loads) as the well, ceiling fans, and refrigerators. In my quest to figure...

All communication is by email, and yes I have kept them! Great advice. Thank you.

Ah, that I can do. Do you happen to know where to get plans for that?

I have been going back and forth with my utility since October of last year. My experienced installer submitted the interconnection request along with all of the documentation. Every three weeks we get a rejection notice, we correct exactly what they are asking for, and re-submit. Then we wait...

Sounds simple but probably not a project I am comfortable doing as I am not super comfortable messing with 240v especially when it involves expensive HVAC equipment. I did think about using a Home Assist type of hub, so that might be an option but was hoping someone else had faced this issue and...

That’s an interesting solution, is it diy friendly?

I have two 3-ton HVAC units on my house. Both have a micro air easy start, but I want to employ logic that if one of the HVAC units is running, the other one will wait to run until the first one cycles off and vice versus. I have simple time-based programmable thermostats now and am sort of...

Much appreciated to all! Thank you.

My plan was just to parallel the two new eg4 pro’s together and then come off one of them into the inverter, but instead i think you are saying I should use a bus bar to parallel them together and then use the same wire length I used from the original battery array to go from the bus bar to the...

So, just to be clear, even though I am going into two different battery terminals and each battery bank is a different size, because they are the same chemistry the Soler will charge them the same? Is that correct?

Thank you for the reply!

Noobie Q: I have a Solark 15K, currently powered with only 6K of PV, and charging 25Kw worth of EG4 Lifepo4 Batteries. I am in AZ with a large all electric home (two 3 ton HVAC (Both with MicroAir easy starts), Oven, stove, well pump, booster pump, 40,000 gallon swimming pool, separate spa...

Ok, perfect. Thank you!

Hi 1201, Thank you for the input! Currently I have twenty-two REC 260w panels in three strings feeding the inverter. There appears to be three more PV inputs. So, would I take the 400w panels in just one string into the inverter or should I break it up into three separate strings? Are there...

So your inverter supports all the loads from pv and battery and when battery gets low then the power comes from the grid? - Yes that is correct. Since you are already connected can you find the labor and electrician to add the additional panels for less? 6kw of panels is about $1800, and...

Hi OzSolar, I noticed that myself as I initially had my pump turned all the way up to the max. In 8 hours of pumping I was consuming (this time of year) about six hours direct from PV and then about two hours from the battery. Xilla

One more thing ... I have a quote from my solar installer to add another 6k worth of panels to my Solark system. He wants $11,400. I would also want to couple that with another 20k worth of batteries. All in, it would cost me $17k-ish. The Growatt inverter is $400 delivered and I can but cheap...

I have a Solark 15kw Inverter, powered by about 6Kw of panels, and backed up by 25.6Kw of Eg4-Lifepo4 Batteries. I used about 48kw per day of grid power in the fall to the spring and about 102 kw in the summer ... I live in Phoenix, AZ. Since I commissioned my system, I have been averaging...
