Split system (3 + 3) which inverter(s)???

[Stephen]

We have won a job installing a split system with three Suntech 250's at -10 degrees from due south and another three at +80 degrees from due south.

My initial choice was to use Enecsys Micro inverters but due to these not being available until mid October and the customer wanting the system installed ASAP.

I don't think I will find an inveter this size with two MPPT's, all of the usual makes are too big for three modules and a Soladin 600 is too small. We also need to take in to consideration that the customer would like to be able to monitor the system.

Your feedback would be greatly appeciated.

Is there no reply to this post because there is no sensible options available?

Sorry if I'm being a bit dense but how could you win a job if you don't know which inverters you're using?

 

[BruceB]

A couple of options for you to research:

- A handful of Steca inverters
STECA StecaGrid 300 and StecaGrid 500

- A Power One Aurora PVI-3.0-OUTD with a lowered Vstart if necessary
PVI-3.0, PVI-3.6, PVI-4.2 | Power-One

The initial choice was to go with an Enecsys inverter but these are not available until mid-October. The customer would like the system installing before then so I am looking for an alternative.

I guess I'm still sitting on the fence with micro inverters and I struggle to get anything for small systems like this anyway so we tend to walk away from them. I'll be having a look at the Steca stuff Bruce has linked to as well . I suppose we're lucky most of our systems are 4kwp so I don't have to look at smaller ones too often.

Far from Spalding this job?

 

[Stephen]

Yes, quite a distance to be honest

Thought it might have been a job that a friend asked about a couple of weeks ago.
