Hi Jeroen

That was a surprise - do you have 1 or two strings attached to your inverter?

Er have quite a few 3000's that work only with strings = 2, so it's probably 
the manufacturer having changed firmware. Eversolar has previously been 
helpful, so I'll ask them. 

When was your inverter manufactured?
Did everything else work well? I have very limited feedback, and it apprears I 
have to migrate our of code.google, as they shut it down this summer.

I have 1 inverter TL3000 from zeversolar (is that a clone of eversolar
maybe?), i have 3 panel strings according to the crew that placed it.
How do i know when it was manufactured ? I know it has been installed just
last week so its all fresh to me.

Migrate from code.google.com to sourceforge.net, thats where most open
source is beeing held at ;)

I'd like to use the code to make a daemon that sends passive data to nagios
using the values in performance data so pnp4nagios can make pretty graphs
for me, ill get back on that later ;)

Br,
Jeroen.

Just some information. Eversolar changed to Zeversolar for whatever reason. Who 
knows, but they are the same.

I'm thinking that because the Eversol TL3000 accepts 2 strings in, but it only 
has one MPPT so the plugs are simply connected in parallel internally. One 
string in the software configuration is correct.

The Eversol TL3680 is the smallest unit that has two Maximum Power Point 
Trackers (MPPT) and the monitoring software would have to be set to 2 strings.

Regards,

Steve.

Some extra info :)

I've attached part of the specs for the old Eversolar TL3000 (it shows that had 
two MPPT trackers and the monitoring software would have to be set as 2 strings)

I've attached part of the specs for the new Zeversolar TL3000 (it shows that it 
has only one MPPT so the monitoring software would have to be set as one string 
as the original poster has discovered).

Regards,

Steve.
