I recently purchased a SMA Island 6.0H 11 and wanted some feedback if I could.
Thank you in advance.
My current system:
-Battery battery 440ah;
-Installation Island 6.0H 11;
-Construct MPL makebluesky at 48v with 8 * 270w rec twinpeak;
-Fronius ig30 with 6 * 270w in nickels;
-2 micro-inverters with 4 * 270w Canadian;
- 1 Grid-tie Inverter SUN-2000GTIL2-LCD
SMA sunnyboy Island is not configured yet.
Although the Chinaman even performed very well to date (easily makes the promise), I bought the SMA because it seemed like a good opportunity. If I were to do it later, "I went head-on" ...
What is my deity .....
The idea goes through an investor capable of withstanding most of the consumption of the house (there is sun!) And that allows to have energy when the network fails ... The "chinoca" does not do that.
Before this acquisition, I even came to think of a Victron (the latest multiplus version of 3000). I got to pass cable and set up a proper circuit for the "loads rescued" and everything in case of power failure. Time, with this investor I do not have that possibility, but neither will be precise, because everything passes through it and will have enough power for the loads of the house.
Setting offgrid or Ongrid or others?
I've read enough, but I feel kind of lost ....
The idea of having battery power in the situation of failure of the network, must go through an off-grid configuration or is it possible with on-grid as well?
I will pass 2 cables into the inverter Ac1 and Ac2: one for the generator (it may be the network) and another the loads and sunnyboys (I do not have it yet, but I am aware of the advantages to have).
I read of the possibility of a contactor between the generator and the Island, because of the generator (which in my case would be the network). It is necessary? Is it mandatory for the system to work? If so, what type?
Note: I would like you to speak about the advantages / disadvantages / possibilities to take advantage of the material I have (especially the mppt, fronius and micro-investors) instead of betting on a sunnyboy.
If you tell me, by your experiences that it is better to sell everything and buy everything SMA will also be the way forward.
