I do not want to use more of your time. Please know that I really appreciate the help provided by all of you. Thanks. Frank

Changes where made. So far so good. At 9:30AM I am producing about 2400W. And new externals CT's seem to be working nicely.

I hope you do not feel I hijack your thread. But SunDave said previously I been asking if my Pyte E-Box-48100R behavior is correct, constantly drawing little currently, some of a minimal ripple. Here better seen at the morning when power are small. SOC 100% but, see the constant battery...

@Oldphile Thanks for your Ideas. My designed setup do have both "critical loads panel" after Solark. And I also have a "Main Panel" before Solark. The main panel is needed because I do have a swimming pool pump that requires more power than Solark can supply, so it is tied to grid. Now the...

@Oldphile Nice info. I guess I need to check on a full sunny day. I guess I need to refer to the Specs on my panels. I think they are 8 "JA Solar JAM78S10-420/MR". 2 strings of 4 panels each. But in the event string voltage is as designed, Do you have any Ideas what could cause a drop in...

I have a few questions on battery. Lets start with the 1rst one. Battery Life Span Provider give this info in "full charge-discharge cycles". Now in reality most batteries are partially charge-discharge multiple times in a day. Most cycles around the top charge state. Lets give for...

Ups, after I posted I found interesting old threads. https://diysolarforum.com/threads/cycling-degradation-estimation-we-are-not-doing-100-dod-daily.98156]Cycling Degradation Estimation: We are not doing 100% DOD daily Cycling Degradation VS Calendar Aging w/ LiFePO4 Batteries Used for Solar...

I have open sky, and all solar panels point same directions. Yes the installer did split on two string of 4 panels each. You are my hero.... I suspect that with this method I can better understand what my PV system. Hopefully I can see better the peaks and not just an average. Now it late so...

I just find out, there is no rapid shutdown devices at our roofs. Due to Hurricanes, almost all structures are concrete. So there no Firefighters nor emergency personal climbing to our concrete roofs. There is no way that emergency personal can try to break concretes roof. So local state...

I guess I should had put more data / info. Let me see what I can upload without filling up this page. NOW PLEASE keep in mind that even when I understand the math and electrical concepts as I am an engineer. My experience with solar energy is limited. So take my analysis as what I expect and...

I know it may be late. But I read: I was having issues with using multiple batteries in parallel, the issue is 1 of the 4 was running an older version of the firmware. They must all be on the same version to get communication to work properly. see: In post...

You are correct from SolArk manual : SK140-0005-002-8K-2P-N-EN-Manual-1.pdf Input Data (PV) Max. Allowed PV Power (STC) 11,000W Rated MPPT Operating Voltage Range 175 - 425V MPPT Voltage Range 150 - 500V Startup Voltage...

Lets talk about unnecessary high Battery consumption, specially in what I believe is Float voltage. Lets give you an introduction. My Solar system was wrongly set up. As result I produced only 5.8kw daily and of that my batteries consume 2.5 kw. I know ridiculous. I had a Solar system in...

The following are the current settings: And as I say the battery is currently disconnected but it setting is as follow: As a Note: I know Battery "Max A Charge" it is reading 60A, I do not know why the installer did that. Max charge/discharge should be the minimum of Max 8K = 185A...

Hi every one. This is my very 1rst post and I do English as a second language. Hopefully I do not break any rules. I live on an Island on the Caribbean, So there is no National Grid and same energy cost ALL day. My system is Grid Tied with: Solark 8K-2P-N PV:3360 kw dc , ( 8 x 420w pv’s)...

Oldphile I was wrong, I was looking at the wrong specs. After double checking at my combiner box in the roof, I see now I need to recombine at the combiner box. Sorry for the previous post. In fact I edited and deleted the wrong diagram. Frank I already moved my CT to the Grid Meter box...

@ I do have BMS Cable hook to Solark 8K. And using the idea @Oldphile posted figure with BMS info. Here is mine: HAHAHA BMS claims it uses NONE or 0 A constantly except for the 9 A Spike at 12:09 PM. In mySolark reports for consumption ( at 4:30 PM ) See how SolArk 8K blames 1.5 kw for...
