Hello, I'm going to build my own 24v system on a hand truck with an electrodacus and 8 100 ah Fortune cells, but I was wondering if you suggest the Growatt or the MPPT all-in-one and why? It seemed to me that Will upgraded to the Growatt for his 48v setup, but I didn't know if it's an upgrade on all levels or not?
 
They are essentially the same units. Both made by the same manufacturer and put into different cases with a few different features.

Since you plan to use the Electrodacus, it may not be compatible with either. It no longer uses an external relay to cut the line. It uses a relay to shut the inverter/charge controller off.

 
Oh, that stinks, so that won't work at all or could I wire it some other way?
 
Man that manual is badly written and obviously not by a native English speaker.
