I think those Morgan guys are not serious.

I have sent a mail to them requesting for account opening form, yet no one has responded.

Please, is there another way I can go about this?

I already have *a Chaka* account but I can't do much on it. Na online something and I don't want stories that touch.

As I have used Meritrade I can say they have excellent communication. Perhaps the reason they are more expensive

Youngzedd:
Any 3kva - 4kva hybrid inverter brand with MPPT controller?

Try felicity

mctfopt:
How about the MG variant? I notice many don't seem to talk about it.

MG preceded the GK, the newer model has more features.

earthrealm:
so with the recent fault developed by your mpp inverter, after barely 8months in service, would you still advice people to go for it?

Absolutely, if I had the option I will still go for it. I have a rough idea of what may have been the cause of the issue I had with the inverter but I don't want to state it as it's not what I know for a fact, also because it's not what can be easily re-created. That said, I think I may go for the MK especially if I have a 48v set-up but for now so long as I can get clear LOS to my panels and if it's a 24v set-up it's GK.

mank1234:
Th error message doesn't look that serious?

Literarily yes, but according to MPP once the Comms panel is unable to interact with the inverter, the inverter won't work. So waiting for Comms replacement boards.

Deluxe8000:
But the superchargers overcharge the battery if not checked. pls who has a rectifier or psu of 14v to 15v to sell or build. I believe if i can get it my battery will be saved from overcharging or is there any correct automatic smart charger one could get? Famicare is not smart at all.

That kind of battery, lithium or lead acid?

NiyiOmoIyunade:
@ OjeySky, lovely graphics and monitoring up there, looks uncannily like EmonCMS but your signature web link is to PV output? I just set up a monitoring dashboard on EmonCMS very similar to yours but yours is far ahead in beauty.

I will connect with you directly - the Victron VRM reporting and dashboard portal has not impressed me with its graphics and visualizations.

Yes it's emoncms can be reached at https://prognathous-tropicbird-1681.dataplicity.io/emoncms/dashboard/view/oj-solar

pls sir do you have the idea of how much I can get a Toyota Sienna 02 catalyst ? Thanks

No idea, am not into parts business

ceaser:
Best option is to bite the bullet and going 35mm for the current set up.

But what happens if I decide to put a 3rd 60A MPPT SCC and maxing it out, thereby jacking up the SCC terminal to battery terminal current from 120A to 180A.

Is that a safe current to have around?
Is that safe for 35mm cable?

Will that still be charging the same lithium bank ( Which is less than 200a)? Even though lithium na current guzzler I think 0.5C usually should be a limit you want to go, besides your battery BMS may also be a stopper.

Edit: Well addressed by @NiyiOmoIyunade guru himself

NiyiOmoIyunade:
Internal calibration and measurement accuracy.

I find the Victron BMV to be pretty accurate and asian origin equipment to be very inaccurate when it comes to measurement.

Two things you are battling when measuring voltage or current from an inverter

1) Increased resistance and Voltage drop as you pass large currents through the inverter to battery cable. Thesame cable that is carrying the amps is where the measurements are taken off.

2) Internal circuitry calibrated for ball park vs industrial grade measurement accuracy.

Even in a premium inverter like Victron who have voltage sense cables separate from battery cables, the voltage readings are still off relative to my BMV and Smart Battery reports whose data I independently confirmed with a Fluke meter.

In disgust at all this, I set my Victron BMV 700 as the 'Battery Monitor' for the entire system on my Venus GX. After a few weeks of observation, I decided it was better to use the Smart Lithium Battery itself as the single arbiter of voltage and current in the system so I set the GX to use PylonTech battery as battery monitor.

I have three Victron installations done in early March all using either Multiplus or Quattros and no GX device to control things - the absorb target voltage on all the inverters is set at 51.9v and in reality the voltage the inverter puts at the battery terminals is 52.4v!!!

All these installs are PylonTech which are extremely voltage sensitive, anything from 53.5v the BMS would go crazy on you.

I read on the Victron GITHuB that Victron wants to include voltage calibration in future firmware releases... I guess they are listening to field complaints

In short, trust the BMV 712 you have if properly calibrated. Victron went to great lengths to make a very accurate device.Take the Felicity's readings with a large pinch of salt.

Extras - Fangpusun CC amperage measurements - very accurate.

Fangpusun BMV clone measurements - inaccurate.

MustPower Type Inverters and products in general - voltage and amps very inaccurate.

adrusa:
Check with a clamp meter to see who is telling the truth and use that to calibrate the BMV. Calibrate your inverter too if that is possible.

Thanks folks

adrusa:
Which one is higher? Are you using a victron cable or a DIY cable?

When charging inverter is higher but when discharging BMV is higher. Yes am using victron cable

Folks I recently introduced BMV 712 to my setup(great tool by the way), but I noticed there is a 5A difference between what inverter display as charging current and what is actually seen by the BMV. Has anyone experienced this before?
Am suspecting it's probably wire+battery resistance but like to hear if anyone is getting actual figures on theirs (both sides)

mank1234:
Hi. What caused the GK failure?

No idea, just got home to meet warning 32; Comms not interacting with the inverter

ceaser:
Thumbs up.

Your PIP-GK, repair is still pending àbí? Covik 1-9 things.

How were you able to get those graphic outputs charted? I though is was an exclusive preserve of your GK, but now that you've changed the inverter you still get graphic interphase.

Felicity is a PIP clone, so I still get data from it for my emoncms processing (though not as much as the PIP), it's the reason I went for felicity as a temp replacement. I hope my PIP will come alive soon enough hopefully covid-19 will get past us sooner than later.

There are some paper loss that are as good as realised loss in terms of permanence sha.

Those that bought IPOs of Transcorp, Japaul and VeritasKapital Assurance 12 years ago can attest

Kai this one pain me sha

Help my portfolio, people.
My Zenith is now in red to the tune of 25m. Help!!!
UBA is 6.5m loss.

I think this is when you probably should forget your login details and let this storm pass, you will laugh lass lass

How did you refund the sellers? I was in similar situation and I was wondering how to reimburse the sellers?

I notified the seller and they ask me to place order for an equivalent item in their store and then put a note for them not to ship.

ceaser:
Indeed, what's your array like, like what's the total installed capacity?

It's in my signature.... It's 2.25kw total

Hello Nairalanders, please I need advise in investing my money. I have some money, about 2,750,000 naira I would love to investing for a 6months duration (till October).
I have done researchs about treasury bill and fixed deposit ,but i can't decide on which to go with. Treasury bill are currently at an interest rate of 3.2% but I don know of interest of bank. I would love to get an interest of 10% for a 6months duration, I don know if that would realistic in our current economy.
Please if could get advice on the best rate I could get on my cash ( #2,750,000) be it treasury bill, fixed deposit or any, I would really appreciate it. ....... Also I would love to know if anyone could confirm if " WEALTH.NG" is real as I saw and intrest of 10% on a 180day treasury bill investment. Thanks in advance...!!!!

Try farmfund, you get 30% after 9 months. https://farmfundsafrica.com/portal/login.php

My purchase protection runs out in 5 days. The shipping and delivery was supposed to take 3 weeks which will elapse in 5 days.

I've sent the seller a request for purchase protection about 3 days ago now yet no response. Of nothing happens in 5 days time, na to open trade dispute for non-delivery sharp sharp. 34k no be small money to forgo for AliExpress.

Me I don't send request(make seller no think say I dey beg ham), I just wait till the countdown elapse and then I push the dispute in, but 90% of the instances seller extend before the countdown elapse. That said, I have later received refunded item in the past and had to return the funds back to the seller.

Average harvest of 13Kwh- 18Kwh. The sun was smoking hot today. almost hitting 19Kwh mark
for your 2400w panels expect an average of 7Kwh - 10Kwh daily weather permitting.
with the stay at home order, boredom has kicked in and I literarily just seat and stare at the ICC software to see when the solar panels hit peak
more like watching a wet paint dry

That is indeed my daily hervest range.

Zenith, leading the race to.....

Abi o.... Bought zenith and I saw an instant 3% loss on page refresh, and even plunged further down

JaySterling:
Hey guys, I want to go totally off grid

But I guess it’s not all possible

Because in my current setup, PHCN light from the mains charges my inverter

But now, we have not had light in my area for over 24 hours

Does that mean once my inverter battery runs out, I’ll be in total blackout ? Since it’s the Nepa light that is charging the inverter

Is there anyway my installer can reconnect the setup in a way that the Solar panels charges the inverter too?

Thanks

You can connect solar panels to charge controller to charge your batteries.

ceaser:
True usually, and that applies for good LFP because it seems some marketers are pushing substandard LFPs into the market now that renewables are gravitating to it.

And yes the price is usually in the same range.

A 12v 40ah LFP is around 57k, 12v 60ah around 80k, 12v 100ah around 110k, 12v 120ah around 155k.

Good Pb-acid batteries are in that same price range for double the AH.

Ojeysky uses 24v LFP so he'll be in the best position to give you how much he procured his monster pack.

I think you've done justice to the question. My pack was 450k which is the equivalent price for 4 12v quanta batteries. However I still get space, cycle and charge/discharge rate advantage with LFP

BetaTechnicians:
I saw a 12V 50AH lifepo4 advert and was thinking of getting that, so just trying to get smaller peripherals for it.

Okay that's indeed small I won't worry much about the type of CC then but if you are looking at increasing capacity in future then it's better to plan for future scaling by getting good CC so you just have to worry about panels and batteries in future.

BetaTechnicians:
It's just a small setup & I don't see the need for a mppt cc due to cost.

Hmm.....how small?

dicksonadams:
But with movement restrictions, how do one get his car from the port?

Unless the car is already at port, an order placed now will take another 8 weeks before landing. Things should have gotten better by then besides I know folks that still picked up their vehicles at port today. Looks like port is operational and it's based on govt directive

BetaTechnicians:
ojeysky, ceasar and other lifepo4 users, how would you advise using a pwm cc to charge a lifepo4 battery?

Unless you have the pwm already you are better off with mppt so as to maximise the panel capacity because lithium will typically want to get as much current as possible

This is inspirational.....but its gonna cost some good bar, as in damn real good bar.

Please I drive a Lexus ES 300,it makes a loud sound when you start the engine in the morning, or when the car has not been driven for 6hours. The sound decreases within 2 -3 seconds after the engine is kept on to normal. I was told by a mechanic that it's the oil pump. He advised me to change the oil pump. Please, I want to know the cost of an oil pump for this vehicle.Could this be also not the oil pump.

It's normal for a car to have cold start (with high rpm) and should come down thereafter. I hope your cooling system is on default settings

anjilgreat:
Yes, cheaper is an understatement! . I use both morgan capital and meritrade but can confidently say morgan has greatly improved and impresses me more.

It's good to hear that you've experienced both, I have only experienced meritrade for a while and think they were quite responsive, is that the same with Morgan?
