solar energy system
IM triyng to installa system with solar Energy. HOw do i choose the inverter and controller ?
Im triyng to instal a projec with solar panels, i need them to give me 26 KW per day. but i never tough it willbe so difficult to find an inverter and controller..there are so many on themarket.. idont knwo wich one is better for my needs 
you need to buy one that can handle what your panels can produce at max output plus a little.
say you want 26kw but your panels can produce 35kw on a good sunny day. If you buy a 30kw inverter, there is a good chance you will fry it.
My advice is read up on your panels and find out what the max they can produce is and then start looking. Even though you will have some loss in the transfer and conversion from ac to dc, it is still better to buy more than you need. That way you can upgrade at a future date if you decide you want more and dont run the risk of having power trip failures or even worse destroying your entire system.
There is alot of information available on this topic on the internet if you search for how to choose and inverter. Some will give you a formula, say 110% of desired output, others will say this is not needed. Read about how to choose one to fit your demand then go looking for one that has the price and features you need.
