I need a minimum of 48kWh useable capacity. Looks like 64pcs will do the trick... When is the next group buy?

MontyNG:


Interesting... And I'm glad you brought this up.

So in my situation, PHCN is N60 per KW and power is almost 24/7. Even if they take it, it's typically not for more than 2hrs a day. I have to be practising load shedding in my house, just so I can afford it by turning off power from 11/12am till 7pm in the evening. Even with being economical, I'm still using about 800 to 900KW a month which if you do the maths, it's costing over N50k per month

I'm in the middle of building a 5KW system with lithium batteries. and I've calculated the payback period to be 5 to 6years. So for those paying N30 per KW, your payback will be over double. BUt then, the major advantage is I will not have to be so power conscious anymore. Regulating consumption will be a lot easier since I've also made my house completely smart. So I can make "smart rules" to keep consumption optimal always so I would never have to rely on the grid. (Or at most Maybe 5k per month or something)

That's the plan anyway

@ OCTAVO,
The problem with the second option is that you waste productive time monitoring your system like a hawk instead of drinking beer.

That same switch/plug if flashed with Tasmota firmware will open up a lot more possibilities. If you don't believe me, ask Ojeysky.

OCTAVO:

It's actually getting the job done nicely with no issues. All I need it to do is switch ON/OFF anywhere I am.
However, I may still consider flashing Tastoma firmware just to get other functionalities.

ojeysky:


Okay it does accept tasmota? That's cool. I only use tasmota on my sonoff switches

OCTAVO:

Not quite sure if it does. From the little checks I did, I found out sonoff switches works with Tasmota.

ojeysky:


I use tasmota on sonoff it works flawlessly, it's useful if you want to automate without internet connection

Please does anyone have an idea how many solar panels a roof of 13m x 9.2m can take?

OCTAVO:

Will you be able to control your device from anywhere without cloud syncing?
I think that may not be possible if you are not connected to a cloud hub.

Oshomo12:


Hope the shape of the roof is plane, no too many corners/funny stuff? What solar panel wattage are you looking at, 255-450w?

toluxa1:


Flat roof.
380- 410w should be OK.

OCTAVO:
This first device (picture attached), is very fantastic and gets the basic job done, however, it has a limitation which is quite worrisome. When you program it to power on at a certain time and you leave home, weather can suddenly become cloudy or even rain for hours and your batteries will be depleted seriously (which you may not want) because of unavailability of sunlight.
This made me to think of a better alternative that gives one more control, preferably can be done remotely anywhere (I'm a fan of home automation). After an extensive search, I came across the second device (picture attached). This device gives my kind of desired control, all you need do is to sync it with a dedicated home router. It's called SMART PLUG and works with other home automation apps such as Alexa and Google Assistant. This is more preferable, you can get everything done on your phone, it has a programmable timer also, instant ON/OFF anywhere you are in the world. Someone may find this useful.

olopan:
That second device, I have looked out for it for quite some time.

I think it works with Growatt readily, as the option of smart home is available in the shineapp

Where did you get it and for how much?

earthrealm:


The gens output is not clean, either voltage is below 200volts or frequency is less than 45hz.
If the gen has not been kazeemed, a change of avr may correct this issue....

Locate a gen repairer that knows his onions, and not a kazeem, who would know what frequency is

maklelemakukula:

Hi, have you corrected this by now? Are you still having same issues

ojeysky:


Then try this; disable AC charging on inverter, run the gen through the inverter and then power the freezer from the inverter. Let's see if that works out fine

Lol. +1 for tasmota on sonoff devices with nodered, especially the ones with the power monitoring which will allow automations based on your consumption / solar production for example. Not really one for voice commands via alexa / google assistant / siri etc...but i believe you can also add this via nodered or Home Assistant.
Interface via a telegram bot / the home assistant app through a private cloud and everything is vely vely hallright.

finecheek12:
is the gen working well with the freezer now?

Valto:
u can team up with toluxa1. contact him or me, for heads-up.

adrusa:


I didn't get your mail. I got a nairaland notification and I responded.

OCTAVO:

-Can one get sonoff devices already flashed with Tasmota firmware?
-Is there any fairly stable and usable android app for Node-red? Or one will always have to rely on their website for automation?
