GeorgeD1:
all,
its been more than a year now since I started using my solar water heater.
in the next couple of days I will be doing a review of the journey so far.
a few surprises and a lot of flaks too. it has been anything but a dull
experience.

pls can someone help me, i want to knw weither Chinese made modifier sine wave inverter of 2000watts can power a small size refrigerator of 100watts, LED TV of 60watts, satellite receiver of 25watts, radio of 120watts.

Thank you. They are about 3 feet long. 36 inches. Weigh about 55lbs each. Think about it though. That is 62.5 AH at 48V in batteries. You can us 56 AH of it. Very Impressive. I hope all is well with you.

sinistrian:

Compare the two graphs below. The frequency of the troughs show how often the sweep is done, while the the depth/width of the troughs in the graph indicate how far it fell and how long it took to get back to Vmp.

The first one is the fangpusun with intermittent clouds passing over. Whenever it's overcast, the
controller drops output and then starts hunting for the max power point. There is an annoying one around 2pm where it took a long time to get its wits together.

The second graph is for the tristar (low power output in the morning cos we were not home and all appliances were off). The troughs are not as deep/wide and yet they are more frequent, indicating that it detects the Vmp quickly after the clouds pass. This graph is not a great comparison as it wasn't too sunny today. But this result looks promising.

NiyiOmoIyunade:
VmP 37.5v × 3 = 112.5v

VoC 45.9 × 3 = 137.7v

Bear in mind these two parameters are at 25°C STC temperatures and actual voltage will derate based on a known temperature coefficient for our ambient weather here in Lagos around 28°C to 35°C

Regardless, these are both within the tolerance for the MorningStar.

There is a derating algorithm designed into the MorningStar where if the VmP gets into the 125v range it throws a fault code 'High Array Voltage Current Limiting' and throttles back on things to keep everything within tolerance.

See below nameplate of the Canadian Solar 330w as well as my max array voltage over several days.

Not only Axpert but any inverter which is paralleled requires the same battery bank ( exception is grid-tie inverters running directly from panels)
The same is true if you need multiphase setup
The reason being the battery and AC side is not galvanically isolated and for paralleling the reference -ve ( or +ve) should be same

for axpert you need a parallel kit and have to replace the card inside both inverters.also both have to be connected with datalinks and current sharing cable ( see the ugly cable between two of my inverters )
also, cables from the battery and input-output AC should be identical and preferably similar in distance to allow perfect load sharing

DMerciful:
In as much as I hate generators, a small gen should always be available even if not used to act as backup for situations like this. The cost of running a small gen few days in a year far outweighs the cost of having enough batteries to covers for many days.

Just finally moved to my own modest house. Decided to finally take a chill pill on the race for the higher wattage and settle for efficiency on the consumption side. This allowed me to set aside some funds for putting a roof over my head all glory be to God. My 1.84kw panel is all the electricity I need for now. I will connect to the grid once am done with some finishing touches to the house.. I generate enough to provide me 24 hours electricity that meets every basic needs refrigeration, laundry, light, TV, kitchen stuff.

The house runs on LED spot lights the highest being the single 12w kitchen lights. Over night amps draw before sun rise is 75AH from a 24v 200ah battery. I had time regig my setup.. Power drill was a life saver.

In the tradition of the house, I'm sharing my very first installation.

This is my first dealing (3 weeks ago) with kiekie1 and he didn't disappoint. Paid for items on Saturday and by Monday it was delivered to Akwa Ibom. Was initially skeptical about the brand but with his assurance, I must say the brand - Foresolar is beyond expectation.

325W foresolar * 2 for a total of 650W wired in series.
60A tristar MPPT controller with no meter
60A and 32A circuit breaker - wired such that if the battery is disconnected the solar is disconnected as well through the 60A breaker. The 32A breaker is solely for solar.
Chinese meter is for monitoring power into or out of the battery. The monitoring for the controller will be by Ethernet. The router is yet to arrived.

The attached images were taken at 4:20pm today. The total current drawn by inverter as fridge, tv and fan are on is 11.2A. So in essence the current from controller is 14.9A. The setup still manage to pump 1A to 7A during the period it is shaded due to the panel location.

Here is my little story...

21/01/18 Successfully mounted my PV array with 4 x 250wp, 3kw cc
04/02/18 I increased my Solar array to 6nos with the addition of 2 x 325wp PVs
09/02/18 Replaced my 4 x 200AH very old batteries with 2 x 200AH
09/03/18 One full month, I have not used my generator. i only support the system with PHCN.
10/03/18 For the first time we did not have PHCN for a full 24hours and I have depended on Solar all through the day and night with TVs and fans running on auto cruise.

The attached picture is my readings around midday!

Congrats to all of us.

PS: I have contributed my little quota in minimizing greenhouse gas GHG emissions and reducing the impact of global warming to preserve the planet for your kids, my kids and our grand kids to have a world to live in...

I’m eyeing the Mercury 3kva 24v hybrid solar inverter
I haven’t made up my mind yet on the brand to go with for the normal inverter

NoMoreTrolling:
you guys should keep posting your harvests once in a while na!!

not bragging things, just to serve as encouragement for new comers and experienced guys as well.

you wont post now that it's sunny, but when june comes now with one week rain, you will be complaining

so who knows where i can get this dual panel connectors...or what do you guys use to parallel your series d panels.
2ndly am also looking for mc 4 connectors.

idsolar:
@efuro. E11 error occur if ur batr go lower than lvd then goes off immediately ur batr pass lvr presets

NiyiOmoIyunade:
Did I read the picture right? Slightly over 4 hours of 'absorption charge'? Odiqua risky o bros! That is a rather long period to stay in absorb. Are your batteries FLA/Flooded

Think positive grid corrossion

SolnergyPower:
Low battery.

Happy Sunday forumites .. Its been all dusty in my hood ..Ground mount has its advantages as you can easily wash off dirts from the surface of your panels. I had to wash my pv array"300w×8" few days ago , the yield has seriously improved to daily 55-59a as usual esp when we run a 1hp split AC at night to 50% DOD

Ijeoma660:



I added to my PV array to enable my battery fully charge and be on float whilst serving my running loads during the day.

It feels so good to be on free energy most especially when you are on pre-paid metering.

Braaad:
Please, enough of this name calling..... Let's move this thread forward. We have a lot of great minds here. Nobody should drag us to the mud.
Let's do what needs be done and settle any grievances we might have.



I'm currently designing a 10kva inverter for a client.

I think you all should look at it. I'll post more details about it later.

Everyone is free to commend or criticize.

viperVIP:


Exactly my reason for being upset. it will just occupy unnecessary space and affect my next upgrade in case I choose to.
I already have 180w and I decided 200w will be manageable. then I have this Billboard with a conviction that it will do magic.

You all should shut up and stop speaking for JUO . .
Since when did he appoint a mouthpiece in here ?
Or are you his lawyers ?

I also patronize James but via the online marketplace;
where if any issues arise, i can return for refund (or replacement). It's been good so far;but
I will not speak for him in a sensitive issue as this.

Let James speak for himself; let him come to the thread and type something
or contact the plaintiff and resolve it.

Like I always say, too much ass-lickers on this thread.

DMerciful:
In as much as there was guarantee which should be honoured, kindly check if the inverter is charging correctly
cos it did last initially 9hours. I am sure Juo will resolve this in a way that is fair and ensure the integrity of this forum is maintained.

viperVIP:


if JUO thinks time will heal this, I bet not because I am very sure he's seeing all this.
