1 inverter victron 800va
2 200ah batteries.
An 40A charge controller that takes 12v and 24v.
How to connect.
Voltage of the panels?
Voltage acceptable by the inverter?
Anyway, the controller will not be able to handle more than 960W while the panels can provide 1100W, which will be a problem already.
24 panel voltages
The charge controller can take up to 600w (12v) and 1200w (24v).
If the inverter is only running in 12V, there is no alternative but to connect the batteries in parallel to get 12V / 400 Ah.
But then it is necessary that the regulator agrees to load an 12V battery from 24V panels (some do, but not all).
Even if he accepts it, it is also likely that in this case, he can not exceed the 600W ...
So next question: precise model of the charge controller.
This is the model of the charge controller
It takes 24v t 12v.
Since it's a PWM model, I do not think it can work with a 12V battery and 24V panels.
So, I do not see any solution
In my opinion, it is necessary:
- either change the inverter for one that accepts 24V input (this may be the easiest)
- either change the controller so that it can convert the 24V to 12V (more expensive but it would be an opportunity to choose a MPPT model)
- either change the panels to have panels 12V (damage)
Thank you for the link.Sadikh wrote:Mcie mr gaston for your clarification. Here is the link you will see all information about the charge controller https://m.french.alibaba.com/p-detail/H ... ications!!!
It's still very light as a description (and it corresponds quite to what I had found elsewhere).
You can wait to see if someone else goes by and has better ideas than me
