Please advise

Do you have a solar charge controller in mind? Or a budget? Or goal (cheap and cheerful or rugged and dependable)?

Great thanks
Will do the math asap and will post it to you.
Thanks for your help

The best i came up with. Good number of sales and reviews. But what do you think
€ 57,72 22%OFF | PowMr MPPT Solar Charge Controller 60A 50A 40A 30A Backlight LCD 12V 24V 36V 48V Solar Regulator for Max 190V Solar Panel Input

Before you can select an SCC we need to know your energy use. That will determine the size of the SCC (charging amps).

I am not familiar with that SCC but seems to be known as a knock off of a knock off (cheap and cheerful).


and all threads with "PowMr MPPT":

The SCC is the heart and brains of your solar setup and in my opinion is the key place to get something good, especially if you are going to rely on your solar. If you want something in the reliable and long lasting realm, I would look at Victron products.

Based on your array, and assuming 12v battery, this comes to mind:
280w x 3 = 840w
840w / 12.8v (nominal battery voltage) = 65 amps

The Victron 150/60 comes to mind (150v max input / 60 charging amps)


There are quite a few SCC's between these 2 extremes.

Thanks
Huge difference on price! Why? Nevertheless i want to get the best. But as I mentioned earlier i might want to increase batteries and voltage. So i thought to start with good but cheap gadgets to catch up with my learning and surely soon I will want to increase power

So it sounds like you are set on the PowMr. Do you know the max input volts for the SCC you want?
We still need to see if it works for your 3 panels.

Good morning !
Just checked the energy audit. I'm a bit confused on what to do. Can't find a washing machine in the list or any other big consumption units like a.c.

Are there any labels with watts, volts and/or amps on these?
I am guessing 240v 50hz euro current right?

Or, maybe we can look them up on the internet.
I found this: https://www.energuide.be/en/questions-answers/how-much-energy-do-my-household-appliances-use/71/

About half way down found a conventional washing machine:

Convential washing machine 200 cycles/year 270 kWh

This comes in at 270 / 200 = 1.35kWh per cycle. (1350 watt hours per cycle)
Your batteries will contain 280ah x 12.8v = 3584 watt hours (about 37% of your total battery capacity).

You air conditioner should be rated in BTU's or something that we can use to get to watt hours per day.
1 watt = 3.41 BTU
Take a guess how many hours a day it is actually cooling with compressor running.

Its a bit of work but all for numbers we need.

Thanks again
Yes 240v 50hz.
For the washing machine we do fast 40c wash for 30min 2 x week.
A.c I'm not bothered at this stage. Only for future reference.
For the fridge freezer i attach a photo with specs

It says 185w. I am not sure how accurate this is but lets use this number. I will estimate (correct me if i am wrong) that if its like refrigerators/freezers in the US, it runs about 1/3 of the time (20 minutes per hour).

185w x 24 / 3 = 1480wh per day (your array will need about 2 hours of full sun to cover this)
