Thanks, i bought the growatt 6kw inventer from fouani store

Cool. The solar panels can also be gotten from there. Make sure they are above 600W each at least.

yes 10 hours including night time

How many solar panel should i add to this set up and what should be the number of battery?

Rough estimate based on your aforementioned loads give or take:

1 40 inches tv, - 100w or less
1 deep freezer, - 150W or less
1 1.5 hp inverter ac - 1.5kw or less
1 industrial fan, - 300w or less
1 normal fan - 50w (can be more or less)
2 laptop - 65W generally (if it's not a gaming laptop or MacBook)
1 decorder - 50-100w
i internet modern - 20w
16 bulbs , the low energy ones - 500w or less

Total - 2.785kw. Aprox 2.8kw

You'll need a 30kwh lithium battery to run the night time loads happily. 15kwh lithium battery will be sufficient if you alternate your 1.5HP AC usage during night time.

A total of 6-10kw solar panels will do. That's about 10-15 625/615W panels.

Please experts in the house, any idea what it will take to get 24hrs power for a single room self con.
- 1 ceiling fan
- 1 TV
- Laptop
- Couple LED bulbs
- Dstv and couple phone chargers

Anywhere from 950k to 1.1m depending on choice of brand including installation charge (if you're not installing yourself)

i ant to ask

i will need to power

1 40 inches tv,
1 deep freezer,
1 1.5 hp inverter ac
1 industrial fan,
1 normal fan
2 laptop
1 decorder
i internet modern
16 bulbs , the low energy ones

do you think a Growatt SPF 6000 ES Hybrid 6kW 48V Big PV Input Inverter will be good

or do anyone have any good set up for atleast 10 hours off gride

Great inverter choice.

Does your 10 hours of off grid include night time? If yes then your choice of battery capacity (make sure it's Lithium of the LiFePo4 category) will determine how much you'll enjoy it.

My solar yield this January.

The heat this time of the year caused a significant drop in solar yield. Always remember to factor in the temperature coefficient when purchasing your solar panels so as to have a realistic yield estimate when you factor in the different temperatures we experience throughout the year.

10.2kw sms dual mppt
10.28kw panels (12x440w Jinko and 10x500w cworth)
18kwh cworth lifepo4 batteries ( 2x100ah and 1x150ah)
Solar Assistant on Raspberry pi5
Victron smart shunt 300a
Junktek shunt/battery monitor 100a

Achieved 100 percent off-grid status in January.

Take not, load does not factor in the 100wh consumed by the inverter itself (72kwh in 30days)

Peak continuous solar yield this month was 6,500kw i.e 63percent max yield

Peak cumulative load this month was 5.2kw

Max yield - 34.1kwh on Jan 20th
Lowest yield - 12.5kwh on Jan 19th

Max load - 24.3kwh on Jan 27th
Lowest load - 9.8kwh on Jan 19th

Max solar yield in 7days - 205kwh between Jan 17th - 23rd

Average daily energy consumption 20kwh

Something a lot of folks miss when trying to go the renewable energy route is using energy efficient appliances. Converting all appliances to energy efficient ones is as important as getting panels and installing batteries. As you can see, most of my appliances are energy efficient.

Energy management is also an important factor, I make use of smart switches which are automated to turn appliances on and off for different set durations.

My biggest energy consuming appliances for the month of January:

1. Lg 1.5hp inverter air conditioner 184kwh
2. Lg 1hp inverter air conditioner 84kwh
3. Starlink and own router 59kwh
4. Double door fridge 52.3kwh
5. Chest deep freezer 34.63kwh
6. Heat-pump clothes dryer 27kwh

*Sorry for any typo

Brilliant stuff here!

Which exact smart switch brand did you make use of? A close contact of mine needs an advice or 2
