Yes. You don't need an external anti-islanding device to enable the ESS assistant.
You need a GX device though.

I have mine set as above, but with the LOM AC input 1 and 2 reversed cos my Gen is on AC input 2 and Grid on 1.

DADAL:
Greetings to everyone. I have a Multiplus 3Kva and doesn't have a external anti islanding device. Is it possible to use ESS without installing an anti-islanding device?

We are looking for a Solar Technician that can test and advice on an existing solar system installation in Ibadan. This needs to happen fairly quickly. Please send interest with qualifications via WhatsApp to 0808 214 6659. Thank you.

Just get 2 batteries and 3000w panels according to our resident "expat".

truthbetold22:
Why should I be bitter or jealous over a solar installation? If I had just 2 batteries and had constant electricity, have I not fulfilled the same need as Niyi? Do I need to have 50,000 Watts of Panels when 3000 watts can do the job? I must be very dense

Haba! See the way you're foaming at the mouth... Jealousy kills!!
Earn and spend your own money. You reek of so much bitterness and poverty.

So much bitterness and jealousy in one post!
Projections... You cannot project your lifestyle unto another whose bills you do not foot! Na ya money?

Go which route?

zeestone99:
Pylon we go. Don't worry when I'm done. You would be convinced to go that route considering the size of your array.

earthrealm,
This looks like you want the same Pv array to feed both the Fangpusun charge controller and DC Submersible pump. I've read in several fora that it's not a wise thing to do.
I believe you can achieve what you want by the use of a 12Vdc 2NO2NC contactor.
Connect the pump to the 2NO contact, and the Fangpusun CC to the 2NC contact.
A level float serves as the permissive to energise the contactor allowing the sub pump to refill the tank.
Add a timer in series with the float switch to energise the contactor on low water level between 10am and 3pm.

Remember you will be switching DC under load. Use of a properly sized DC contactor cannot be overemphasised.

Buy locally baba, no take chances o!
I don shelf my China Lithium purchases for now

ojeysky:
I found some on AliExpress but will be good if I can get one locally

@Ojeysky, look ya post and run through ya numbers again.
The thing no jive at all...

So no hope for folks like me with average loads in the KW range

simydan:
I have a 600w stand alone inverter which display function is really great. My battery charges to 14.4v but holds load of 78w at 13.1v and can go like that from 9am till 7pm and still have 12.9v or 12.8v...

When will our teaming smart youths develop a similar indigenous app?

emmanbol:
The screenshot is just for illustrations and not to portray any bad thing. It is to show Kipp can be used in any part of the world, whether Nigeria, US, UK, India etc

Wasted generation... If you design and develop ta similar app as a Nigerian, will you die?

emmanbol:
Dearest Nairalanders.

I will quickly be introducing you to an app you can use to easily call anybody from anywhere in the world. Whether they are your friends, loved ones, family, and you can also connect with new friends.

First 100 download/usage gets a gift from me, emmanbol.

The name of the app is Kipp

You can scroll down to see images of Kipp app. First 100 download/usage gets a gift from me, emmanbol.

Kipp also have feature to record text and voice, watch video, play game, and its all fun.

Check out Kipp on Playstore now. First 100 downloads and usage gets a special gift from me, emmanbol.

Go a step further and put a NEPA driven relay across the BMV 712 relay so that between 12 and 1.30pm if the battery is still low but NEPA is available, switch on the pump if low level is detected. The tinkering never ends

Barezzi:
I put a timer switch in series with a victron BMV-712 battery monitor relay across the second switch(NO) as permissive to energize the contactor/operate the pump. The timer switch is set to close between 12pm to 1.30pm, while the BMV-712 is set to close at SOC > 85%.

The pump will ONLY switch on between 12pm and 1.30pm as long as the battery SOC is above 85%.
You don't want your pump switching ON anytime it likes, simply because water level is low e.g during the rainy season or poor weather.

I can manually override the timer and BMV by simply activating the NO switch. The float replaces the NC switch.

adrusa:
... I actually leave the other switch connected so that I can turn off the contactor/pump whenever I wish. If you don't connect the second switch, you will have no control over the pump, only the float switch will do the control.

No progress yet, waiting for desiji

netotse:
Hey Chief, any progress on your pylontech moves? can I holler at you outside here?

Great! Hit me up via outlook back channel make we tidy this up expeditiously.

mcTrinity:
My boss,
I got them at 55k as of last year... Same price as their newer 305W Mono

Trinity,
How much for those 300w Canadian panels? I also need 9 to 12 pieces, thanks.

mcTrinity:
...Installed 2.7KW (9# 300W) last year for a client and have been seeing, at peak, over 3kw.

What's the ballpark figure of 5 modules, Pylontech US3000B?

desiji:
Sorry but it is if you want all this completely finished product with Warranty, I am using the Pylontech US20000 Plus that cost from my end 1200€ i am now upgrading to 2x us2000plus plus 1x us3000plus which when you change to Naira cost like the 2 Kidneys. but i have the absolute warranty i have testeted the 1 us2000plus for over one year i have about 267 circles on it i can add the others because it is modular

Yes, but a 13.8kwh BYD B-Box "drop-in" replacement will set me back over N3.5m
Do we really need 2 kidneys?

@bolded, I'm not sure you should be swayed by the difference, as it's not a true indication of battery capacity.
While Lead-acid battery voltage will sag under heavy load and Lithium remain fairly constant, the energy consumed should remain the same.
5kwh Lead-acid useable capacity = 5kwh Lithium useable capacity.

I believe why you witnessed an improved performance is because of the higher Lithium "useable" capacity.

ojeysky:
Day 1 with lifpo4.

My night loads was the same (or even more because I did put on my 1.5hp GenPal for about 20min) and I still have 26v reading on my display.
It outperformed my lead acid significantly as I will be at 24.5v if it were my 300AH lead acid.

The bulk charging phase(constant current) is when the battery charger pumps maximum current into the batteries until the voltage rises to the Absorb value.

It then switches to the Absorb phase (constant voltage) where it holds the battery voltage constant for a certain time limit or until the charging current drops to a percentage of the battery capacity. I have mine set to 2%.

At which point it changes to Float phase and drops the voltage to the "Float setting" and trickle charges to maintain that set-point.

earthrealm:
seems victron and by association dont include bulk voltage setting in their devices, only float and absorb
How or what then does the battery use as bulk voltage when charging...

My back up time is getting poorer by the day and i'm also using Luminous, so you may be unto something here.

zeestone99:
Luminous is really messing up big time. I just troubleshooted for someone yesterday. He bought 8 and Two is already giving problem. He said it's not even up to 8months. And I'm like this luminous have not changed

I have, and it's still working perfectly.
I don't use it anymore, as i'm currently looking for a control circuit that can manually select from 3 AC sources (Inverter, Grid, Gen) to feed a sub DB.
Something sexy with a single point of control...

nonoski:
Please has anybody tried this automatic change over and does it really work?

So Flames 320w mono panel is 38k confirm.

justcallmenuel:
It’s a mono panel sir.

Confirm this is a Poly panel.

1. Not all. The cheap 12v inverters typically does not come with a changeover switch built in.
If it's an inverter-charger, then you can be sure it does automatic changeover.
2. 2.4kva... It's always nice to operate equipment at about 50% capacity to prolong it's life. You avoid equipment/component failure due to overheating etc.
3. No
4. No

enet1:
Good Day to everyone,

I have few questions to ask

(1) Is it all inverters that does automatic changeover when there is power outage? If not, how can I know the one that has automatic changeover?
(2) I have a load of 950 watts (14 energy saving bulbs, 5 celing fans, a TV, a laptop and other small loads), Is it advisable to go for 1.5KVA or 2.4 KVA inverter system ?
(3) is it all inverters that come with chargers for self charging?
(4) I have ordered for two new 100ah batteries, can i complement it with one used 200ah battery?

That CC is one of the most useless in the world. I remember my travails with it. I quickly dispatched it with my trusted hammer.

You should have seen the smile of satisfaction on my face!

ojtech8291:
How can I control the frequent tripping flexmax80 even when there is sun sometimes. It is always going to snoozing mood. Why?

@ Hancock, I'm also interested in the US3000 Pylontech batteries.
How many internal organs will get me 6 modules?

Most JWs are confirmed hypocrites! I have lived with quite a few...
