The manual states that these units cannot operate in Parallel the question i have is can they operate in Series

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

 

Hello

what is the KVA of the first inverter? 

 

Got the specs for this site>? Is this the right inverter?https://voltronicpower.com/en-US/Product/Detail/InfiniSolar-E-5.5KW

AC input is 40 amps

AC output of the inverter? 23.9Amps

Think your first inverter is going to work very hard or not at all with the pool and stove.

Both Inverters are the same the Rating max is 6.3KVA on each unit 

 

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. 

I  guess with no comment from the experts this makes you the expert

thank you Barry your replies are appreciated

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 )
