Thank you so much I really appreciate doing business with you! I got home safely.

@All

I have about 10 units of 250 - 260W Felicity/My Home Solar Panels for sale. They are all in good working condition. I just upgraded my solar panels.

Each one is for N26k each.

If you are interested, kindly contact me on zero eight zero three............. .

NB: The buyer will be responsible for the transportation to its final destination.

Current Location of the Panels = Wumba, Apo, Abuja

Thank you.

Please can you direct me to resources to achieve this. I am very interested. Thanks.

If you are not using HomeAssistant, Nodered and MQTT, you are not maximizing the utility of your solar setup.

ojeysky:
Not using HA I think @Ceasar does

isangjohnson:
Could someone please help me with Babaegun and Ativ contacts?
They are members of this forum. Thanks

It's been a very long time! I bookmarked that link, more than a year now(I think). so I could not attach a name to it.
What's happening to the solar generation and battery voltage is at a level I have not been seeing before?

Oshomo12:
Morning my people,
Abeg who owns this setup, link below?

If I had to change anything I would invest in a recirculatory system for the hot water line . Currently takes about 2 minutes for hot water from the heater to clear out all the cold water in the lines and come out hot from the tap. This would not be a big problem in a large household with heavy use.

NiyiOmoIyunade:
Please what tool are you using on your raspberry to harvest this basic data?
I believe the device making the info is a BMV?

adrusa:
By the way your modbus config is missing a parameter called "scale". That is why your battery voltage is 513V instead of 51.3V

adrusa:
home assistant - BMV

.... but mine is controlled by my home automation using homeassistant. The State of Charge (SOC) of my battery and the voltage is fed into the homeassistant through Victron BMV. Any voltage sensor can also do the same. The SOC and Voltage then trigger a normal ac/dc relay to supply AC to the inverter if I need extra juice especially on days my batteries were not filled during the day.

essegis:
I thank God I discovered this group. In the small time I have spent here I have learnt so much here with a lot of side helps. Thanks to the folks making this place go on. More grease to all your elbows. That being said my eyes have seen things. I am still stunned at what I came across between yesterday and today.

So I requested for a MK3 interface to help program my Victron and before you can say Jack Robinson two cool guys raised their hands and vola I was on my way to the island to pick it up without even thinking about any other plan for the day.

I found a museum. One with modern capabilities and set up instead of antiques. I am talking about the system of sir @NiyiOmoIyunade. As I type I still dey try to get my head around what I saw. So many panels, so many Victron, so much power, so much big words I was lost somewhere.

Even when my archaic brain couldn't find a way to get around the inability of the MK3 to connect with my laptop he offered to help and I was knocking on his door before day break today. Baba didn't even mind, attended to me like say we have been growing up buddies. Abeg you can all help me thank him.

And if you really really wanna see why his batteries are called that they come with bells and whistles take style look the attached pictures.

My Oga,

Yes we are based in Lagos just 10 minutes walk from the Lagoon/Seaside .

The area is blessed with abundant cloudy weather, floods and lightning flashes.

To the system - there are 4 CCs - from left to right;

Victron Smart Solar MPPT 250V/100A - 20 Units of Canadian Solar 385W Connected
Victron Blue Solar MPPT 150V/85A - 12 Units of ET Solar 360W Modules Connected - thanks to two trusty NairaLanders
Victron Smart Solar MPPT 150V/70A - 12 Units of Canadian Solar 300W Modules Connected
Victron Smart Solar MPPT 150V/70A - 12 Units of Canadian Solar 330w Modules - will be setup this week as we just took them off the roof of our old location.

So effectively, I was making 12.75Kw of power from a 15.6Kw name plate array on the said day - I am still curious to see what the full 19.58Kw system would do.

16 Pylon Tech US 2000 bricks (8 stacks arranged each side of the cabinet) - that small black box on top of the cabinet is the PylonTech Low Voltage Hub which can help connect I think about 40 units of Pylon Tech together - it is required if you want to interface with the more than 8 Pylon batteries and have them all under 'smart control' - in an open loop system, you will not need the LV Hub.

At the center of it all is the Venus GX (small blue box in the middle) with many wires sticking out - this talks to the inverter, MPPTs and batteries and make sure they all work in perfect sync.

Interestingly the combined PylonTech stack call for 400A of charging current - that is way more power than I would ever want to process through my current equipment - I currently do 245A and may push up to 320A @ 52.5v when done with the install.

At the extreme right is a 15Kva Quattro - in restrospect, I may not have needed such a size or it may have been better to do 3 units 5KVa in a 3 phase config - I may run into issues if I ever want to connect to a 3 phase grid or Generator as I basically wired the house single phase since the Quattro drives everything.

On top of the leftmost Pylon Tech stack are my Raspberry Pi 3 and TP Link Router - together these help me poll the Venus GX for information which I then forward to my EmonCMS dashboard - what I have posted here is the 'family view' so the household can manage power effectively - there is another hidden dashboard where graphs, trends, highs and lows e.t.c to aid system audit and diagnostics are kept.

NiyiOmoIyunade:
Indeed the sun is the answer! She has afforded us a decent living and above all energy security.

NiyiOmoIyunade:
Buying trusted premium products, you will never have regrets - the reliability, performance and bells and whistles are well worth it. I used to think Fangpusun was alright until I started using Victron in my own house and saw it blow the Fang outta the water. Imagine trying to aggregate your total PV generation in one dashboard when the CC is Fangpusun or EPSolar cheesy grin

NiyiOmoIyunade:
All other things being equal, option 3 will keep the batteries in sync the longest and surest.

YOU MUST however use equal length cable of suitable gauge for the parallel runs from the extremost batteries to the negative and positive busbars. The series connections should be equal length amongst themselves too but not a requirement for pack balancing.

You can improve passive balancing by arranging extra wires in parallel between each equivalent position of each battery bank

ceaser:
Well, I'll take option 1.
The distance from terminals pack to the CC appears to be the same in both packs.
Whereas for the other options, there is some difference in the distance from pack to the CC which will invariably impact on the charging current each pack is exposed to (notwithstanding the use of busbars in option 3), the charging expectedly being less in the pack with the longer wires (distance).

adrusa:
I bought the 48v Felicity lithium and my first impression is not good. I tried to do a test drain overnight.
It gave me about 90AH drain overnight. I then set my Water Pump on it to drain it further.
I got to about 115AH when my inverter shutdown at about 49v. I wasn't sure which shut down first,
my inverter or the battery. But the battery was still (or back) on when I checked. At this point, I can not
recommend this battery based on expected AH output.

georged1:
suddenly it feels like dry season all over again. with daily harvests topping 42kwh and instantaneous breaking the 10kw barrier ....
indeed, the sun is the answer!

ojeysky:
Thanks for your response, do you think if I get a 1HP there will be significant reduction in the consumption compared to 1.5HP that does 850w?

ojeysky:
Folks am trying to make a choice on air-condition to use on my inverter system, between GenCool and GenPal which one of them is more energy efficient? Anyone with usage experience?

simydan:
Both will work. But for my personal experience, I'm using a 1.5hp lg gen cool on my 2kw generator and the gen does not blink when ever I put on the AC. Unlike when my 100w refrigerator comes on the gen slightly surge.

GeorgeD1:
.................an enthusiast like yours truly already heavily invested in an oversized array and running an
agm bank pushing nearly 7 years , it would take a little more convincing that lithium is actually worth the effort and cost.
