Hello everyone,
first of all something about me. I am here since i saw a youtube video from Peter Metthews and thaught never ever will it be true.
So i got one "dead" ebike battery for free and tested it. Less then 10 % missing power and i thaught ok i will do it too.
I am not a electrican person, so i have to learn alot but the house part with all the wires a friend will help me.
But i want to learn as mutch as i can since i wanted to be electrican in when i was a child. But became programmer
Right now i have 30 kwpPhotovoltaik at my roof and a Tesla Powerwall 2 (13,5 kwh)running. I am living in germany and from march to October i am 99 % off grid.
Plan:
Add a new 10-15 kwp system just to south, for the new battery and to be in the winter also at 70 % off grid.
Building a 20 kwh Battery for storage.
Setup , so far as i read in here ,will be done with:
10 kw 3 phase hybrid MPPT Inverter 48 V
Battrium
Rack to store all the batterys
How it looks like right now:
Tools i made myself:
Thanks to average joe
Questions right now are :
My Rack is 80 cm long, 60 cm witdh and 100 cm high. What is the best setup for the Batterys. i dont wanna waste alot of space in the rack. I could make a shelf and make them close to 240p = around 60 cm length. idk so far what will be the best way.
I wanna build a very "safe" system since it will run in my cellar. So i just would like to get the batterys charged and discharged with 500 mA and not more.
If i understood in the mppt manual i can set the current and need to calculate my battery that i will just charge and discharge my system by 500mA. Is this true ?
Happy to be here
If there is a chat somewhere i can ask questions and google alot i also would like to know.
thanks
