The manual states that these units cannot operate in Parallel the question i have is can they operate in SeriesSOLARDB.thumb.png.dfb14b8c12ecb353d0d414259d9e86cf.png

The First unit running a stove and swimming pool  ( Gas Geysers )  and the other unit running the rest of the house

The First Inverter has two pv strings the pool to run from 9 untill 11.  The Stove is  to be used  between 11:15 and 2:15   the only load from the second inverter is 200W 

The Second inverter also has two strings and runs the rest of the house just fine.  No extrapower needed from the first inverter.

The Evening load is never more than 1.3Kw will  come from the 1st inverters batteries

neither of the inverters will feed back into the grid .

I am thinking about earth being common in the DBs that could cause a problem

Ok.

Just make sure the settings is correct otherwise you will blow your first inverter. You don’t  want you second to feed back to the first  inverter. 

Let’s see what the Professionals have to say. 

This is risky to connect a inverter onto a inverter.

After many months of getting the manufactures to understand  the question the answers is yes

the second inverter needs to be set to offgird.   ( Which is actually Grid Tie with Backup and no feedback to the Grid )
