Solar Module manufacturer JA Solar unveiled what is thus far the world’s biggest and most powerful panel with an 810 W model. Called Jumbo, the panel has quadruple layouts of 47 cells and dimensions of 2,220 by 1,757mm. This panel utilizes a triple-cut cell design with 11 busbars on 210mm wafers. JA puts the maximum power output at 800 W. The module is not yet in mass production.

JA Solar launched a new 525 W+ panel in May.

That's an impressive performance from a 48v 105ah.

I didn't hear you mention freezers or home entertainer systems in your device usages. I noticed you majored on the power guzzlers in the home.

Just saying.

Javid4me:
It might help if the inverter ACs are sized correctly with the rooms.
The 1 HP is good for small rooms and works well.
The benefit is not felt when installed in a large/larger room.
Try the 1.5 HP and higher in larger rooms.

The LG versions work very well when sized correctly with the room.

I use the 1.5 thermocool inverter AC, initially it was cooling well at L1(lowest speed) but of recent not as much. I am guessing ity probably has to do with the gas level. Overall I will still prefer an inverter AC over the conventional ones. I use both and the surge from conventional AC is just crazy.

What is your Daily usage in Watt hours?

Example mine is 4kwh, So I must be able to generate 5-6Kwh daily if I rely only on Solar.

What I’m planning to use it for is 32LG tv and DsTv decoder. That’s all for now

Hello good evening everyone.... Pls does anyone here know how to repair big ups/inverter that use to serve as backup for server rooms... Or do you have contact of anyone that can. Pls share with me

still in need of a technician

I guessed as much that this was the battery you were talking about. I didn't know these things are still being sold. Used to have it as part of a modular set up powering a 65 inch TV (set to maximum power saver which consumes 46 watts), a startimes decoder (4 watts), DC standing fan (15 watts) phone charging all on a 300 watts PSW inverter. With all those loads, by 11:30pm the battery still hangs at around 12.7v.

Two of it paralled as a pack that is enclosed in those large PVC electrical casings. It was charged only by two units 150 watts panels connected in series to an MPPT charge controller. It reaches full voltage by 11:30am. I can't say how it performs now that it's had another owner for a while.

So for your LG TV, put it on max energy saver. Get two units 150 watts monocrystalline (connected in series on a 20 amps or 30 amps MPPT controller OR parallel on a 20 amp PWM). Set the float voltages at 14.2v and hook the battery to a modest sized 300 watts (600 watts peak) pure sine wave inverter. You may still be able to subsist on a single 150 watts panel though, but don't expect miracles on days the sun is a little upset.

The battery is on "different port BMS", so you should connect the charging wired to your CC and the power wires to the inverter.

Your battery capacity is just around 32 AH at 12v, so don't expect all the backup hours I get on the 60 AH pack.

At first glance, it look spectacular but when you do the maths, it reduces to ordinary.

This 810w panel has dimensions 2.22m by 1.757m. This gives an area of 3.9m2

Now lets look at regular 380w panel. The dimensions are usually about 1.956m by 0.992m. This implies a surface area of 1.84m2

If will now scale up the 380w panel proportionally to produce 810w, the surface area will also scale up to 3.92m2 (1.84m2 x 810w/380w)

Summary (note all the bold figures)

The new 810w panel requires an area of 3.9m2 to install
If scaled up to deliver 810w, the old 380w will require 3.92m2 to install.

Since the area requirements of both panels are just the same, the new panel is just the old panel in a bigger frame. Nothing new on the technological side. Now that the physical size of the new 810w panel is over twice that of the 380w panel, handling becomes an issue especially when installing on difficult terrains. Excerpt the new 810w panel is cheaper than two 380w panel, I will not recommend buying it.

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.

Hi chief @ceaser, please is it possible to connect 2 of this type of battery together, knowing that both of them has separate BMS inside, and if yes, how do one go about it?

ceaser:


Oops! Sorry about that.

Could this be a one off bad experience? Hope it isn't a common thing with inverter ACs.

Users of inverter ACs here, your input may be required.

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...

It's possible. The BMSes are the same specs at least. Connect together like wires, that is charging wires on both together (positive to positive and negative to negative) and then the power wires together (positive to positive and negative to negative) to form common charging leads and common power leads respectively.

The battery is on "different port BMS", meaning that you'll have four leads exiting the battery pack. So you should connect the common charging leads (the same one you plug the AC charger into) to your CC and the common power wires to the inverter.

the Thing is I have 80watts solar panel charging that kind of battery at my parents place so I thought 60/80 should do the magic here at my place too but I’m surprised When you said 150 watts won’t that be too much. I’m just curious please don’t mind My naivety

You can try out the 60 watts and 80 watts panels connected in PARALLEL to your controller. Your load of 32" TV (maybe with conservative power saver of 35 watts and decoder of 4 watts makes a total estimate of 39 watts. Total panel capacity of 140 watts may get you by on very sunny days, especially if you will have to simultaneously use the appliance as you recharge it thru the panels.

Good day sir, do you have any idea how much it would cost me to get a solar that can run for a decent number of hours while powering my system, TV set and decoder and also charging my phones and power bank?
Thanks

Morning people. Can the Fangpusan 150V 70A cc effectively charge lithium-ion batteries or can they be programmed to do so? if so how? Looking at it for a 48v setup. thanks!

Please who has contacts for genuine Jinko or Yingli 385w panels? I want to buy and try a few units as a precursor to using for installations.

Please drop the contact here or reach out via 0.8.0.8.1.1.4.4.4.4.2 as you prefer.

Good day great minds.
I need to extend power to an apartment as a matter of urgency, but I don't want to leave any thing to chance of abuse. Is there any form of control I can implement to limit their consumption if by chance they abuse it?

Thank you sirs

A good properly rated circuit breaker will do this job for you. Ensure the circuit breaker is at your end of the building where only you can put it back or otherwise they will bypass it.
You can even make it two, one at their end and one at your end.

Thank you sirs

These 2 devices together will help.
The first one..you can see the actual and cumulative wattage consumed by them. The 2nd device you can programme it to limit the load they can power.
Eg setting 2amps max, will ensure that any load exceeding 480w will not be powered, instead, it will trip off.
You connect this two devices with suitabbly sized breakers at your end,

As much as I like your analysis Sir, I beg to differ on the installation part. In practice, this 810w panel will reduce the time it takes to do an install. It will also reduce the number of mid and end clamps needed for an install. You are right with the handling part for dangerous terrains but if best and safe practice using harnesses or a MEWP is used, then there is no need to worry.

Let's also not forget that it's advancements like this that have generally brought down the cost of solar panels world wide. Imagine for once that we still had only the 100w and 150w panels, you would have needed a truck load of panels to do installs in excess of 5kwp.

I haven't seen the name plate yet but I also presume that the Voc and Imp of the 810w would be significantly higher than the 380w panels, which give us new design possibilities too. I'm just saying..

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
