How do you setup openhab, mosquito eclipse, solpiplog on pi so that all work as a unit?
Which image do you install: openhabian or solpiplog image? How do you get the other to work adter installing the other image?

Please can I pm you so you can give me your mobile number?

Please Solar experts in the house, can you please recommend a solar that would be able to charge my laptop and phones conveniently and also power my TV set for as affordable as 70k?
Please help.

You can use the raspberry pi image which already has solpiplog, emoncms, vncviewer etc. My number 0 8 zero 3 five 2 three 35(x2)

Since we don't have the data sheet, we can only just make assumptions though. One thing is certain, the 810w panels will reduce the BOS components, which in turn will drive down the cost of an install. Using 3 units of 380w panels to achieve same result as 1 unit of 810w isn't an efficient way to go. The former has more cabling that may cause voltage drop and losses as against a system that already has all that wiring worked into the unit.

We will wait to see the finer details of this panel to see what extra benefits it brings, but I already suspect it would be worth considering as it will most likely change most of our present design considerations.

dapsyra:


The jump from 100/150w panel to 300/380w panel was a technological leap (improved efficiency) which is not the case with the 810w panel. The manufacturer of the 810w panel merely fused two 380/400w panels into one large panel with equivalent increase in surface area and weight.

If the 810w panel is wired for higher voltage, the VOC will be about double that of 380w panel while the ISC remain same

If wired for higher current, the ISC will be about double that of 380w panel while the VOC remain same.

Both scenarios can be easily achieved by installing two 400w panels instead of the 810w panel

From my personal experience! My 1.5hp LG Gen cool has been doing very fine since January 2019.
It cools very well even though the room is large. However, constant cleaning of the evaporator unit is required.

Anytime the cooling effect reduces, I open up the front panel of the indoor unit and do a thorough cleaning on the evaporator coils and cooling effect resumes full blast.

Also once in a while I do clean outdoor unit coils too and I've not had any reason to join the majority of people who keep saying inverter AC is not good...

It is also important to note that, installation matters when it comes to air conditioner. If your installer do a bad job and you end up with leakage, then you'll not enjoy your AC until that problem is fix.

Mine has been a very splendid experience...

Thank you for the comment. I clean the filters. How do you clean the evaporator coil. Thanks in advance

Superb inverter, made by China.
China is vexing these days.
Producing premium products at non premium price.
The german or american version of this would cost a section of ones liver

Wait for the day Niyiomolade would go fully chinese .

Thanks for the reminder about this important maintenance, my filters were quite dirty and blocked, the evaporator was fine and with a little blower that was cleaned. Now waiting for the sun to start smiling to test the difference

chris81964:

Depending on the brand you have, the LG Gen cool has two black screws right down the unit. The screws are located at opposite ends when you pull down the cover below the air vent at the bottom of the unit.

Once that is done, you can pull out the front cover completely starting from the bottom. With that, the evaporator will be expose for proper cleaning. I recommend washing if you go this far, because you don't get to do that all the time.

You'll be amazed to see the amount of dust your indoor unit accumulates. So, washing cleans it better.

Note: You have to be very careful with the coils and other parts like the display and the circuits by the side. You can search on YouTube for videos that will help you do it right.

In support as well. If price is right, then investing in it might be wise

And I see no reason why it shouldn't be cheaper than 2 units 380 watts. The total length of aluminium frame that will be used in the bigger one will be less than the smaller 380 watts. At least two length sizes will be saved.

Jinko 800w panel specs
company says tops 800 W of output.

The 240-cell panel – unveiled at the SNEC PV Power Expo trade show in Shanghai – has quadruple layouts of PERC cells and features a triple-cut cell design with 11 busbars on 210mm wafers. It is the most powerful and the biggest, heaviest device on the market, with dimensions of 2,219×1,765x40mm and weighs in at 43.5kg. By comparison, a 585 W panel unveiled by a competitor this year measures 2,411×1,134x35mm and weighs 31.1kg.

According to the JA Solar panel’s product sheet, the JAM80S40 785-810 HRM module series is available in six versions which offer power outputs of 785-810 W and efficiencies ranging from 20.1 to 20.8%.

Personally, I wudn't go for it,
For my own applications, it doesn't offer any comparative advantage, cost & specwise.
however I believe the manufacturers must have seen a niche/market for it. They wouldn't just manufacture this for bragging rights

I run a timer switch on my freezer so it goes off at 5pm but when there is public utility I manually adjust it to be permanently on, unfortunately this is not so optimal as if utility goes off or on days when sun is not smiling and my battery is depleting am forced to head to location of the freezer to switch it back to timer mode or off as the case may be. Sometimes this happens at wee hours.

Thanks to @ceaser who triggered my curiosity about Sonoff, so I got the basic recently and now I can easily switch off from any location. Unfortunately I got the R2 version which does not have mqtt option (and I don't yet have the ingredients to flash the device with tasmota firmware) so for now am stuck with on and off from the app. Hopefully in near future it will be integrated with homeassistance when my 4CH R3 version arrives or I get to flash tasmota. Overall as it stands it's an improvement over my previous set-up.

On that note, I have a timer switch for sale for anyone interested

Edit: I just realized I was acknowledging the wrong handle. So credits to @adrusa

Have you tried the ATS _ timer switch combo
It's a simple solution, wonder why your mind hasn't gone there

earthrealm:

At what cost and will it talk to my inverter? Can it also allow me switch off the appliance remotely outside/inside of the timing schedule?
Those are some of the advantages of the Sonoff over the ATS timer switch combo

Good evening gurus

Please I need help on how I get aluminium solar racks , or what it looks like of am getting someone to make it. Also where I would get other necessities for installation like clamps and connectors

So in my installs, the usual average yield is at least 4 times the PV nameplate on a good day with ideal weather and sufficient energy demand.

I consider a regular daily yield 3 times the mounted PV nameplate to be unimpressive or average at best.

I kept quiet on this as I had so far not been able to get my large PV array to yield above 3 times the nameplate even though I believe it was pretty well optimised - attributed this to insufficient energy demand from AC loads and refilling depleted battery bank.

Well in the last few days I have had a very full and busy house and this evening saw good yield results from my 19.5kw PV array.

I look forward to a day when the sun and my consumption align and I can gross 100kwh daily yield

ojeysky:
That's X3 your array.... that's cool. It also gives me good confirmation that my 7 to 8kwh+ yield on a 2.5kw array is not bad one for a "non premium" gear, will do a proper stress test after my bank upgrade, but men bros you dey use power o

This is the part I don't understand from you and Ojeysky anytime you post your emoncms pictures. In this post one picture is saying battery 50.7v but 74% while at another time 49.6v at 81%. I have always thought the SOC curve is a somewhat straight line or I maybe be wrong.

Can you please explain this?

We will still port to this 810w. Technology moves, we move

At 81% SOC battery was not charging and was on a load of almost 5kw hence the reduction in voltage. As expected, voltage drop is dependent on the amount of load, the depth would be more of it were lead acid

At 71% SOC battery was charging hence the reason for higher voltage.

Thank you boss.

Well explained!

That is why I always highlight the time of day so that one can put the numbers in context.

Also, pertinent to note the PylonTech is a 15s battery pack so the voltage profile is odd vs standard lead acid.

Standard lead acid can operate between 42v (discharged) to 59.2v (absorb) while PylonTech effective range is 47.5v (discharged) to 53.2v (100% full). If you try to run the PylonTech below 47.5v especially with a large load, the BMS will step in and disconnect the batteries. At 48v there is likely less than 20% capacity left in a PylonTech whereas at 48v lead acid has about 50% capacity left.

Is that stuff manual?

I took delivery of the AC sinometer about three weeks ago. It controls only the fridge. The freezer is 24/7.

Meaning SOC is not a straight trajectory then, where a particular voltage has a representative percentage. Other factors including charging status and amount of load come into play.

Thanks for the explanation.

Yours time schedule is digital mine is manual but they serve the same purpose. So you don't have a Sonoff basic on the fridge?

State of charge(SOC) is determined by how much current left or has gone into the battery. You can roughly determine the state of charge of a battery from the no load voltage.

Think felicity.

Hence the use of coulomb counters (battery monitors) to measure net AH left in a battery.

Voltage is only a roughly approximate indication of SoC. For no load voltage to work at all, you must let the battery idle for at least 12 hours with nothing connected at all.

My battery was at 20% SoC by this morning and the voltage was 48.5v As I type it is at 50v and the SoC is 27%. 100% SoC is 52.5v so you see how voltage does not really tell much about SoC.
