The gen is powering the loads through a bypass breaker so we can't be stopping
and starting it. We did simulate an inverter start by initiating a start signal
and immediately closing the gen feed breaker. This eliminated a sync error but
did not allow the gen to charge.

Hi Wrenches,
I have been watching Solar Edge for a while now and am curious if other
wrenches have been using their product and what they think about it. I’m
generally hesitant to adopt new technology until it has a good track record
but I have to admit that I’m seeing some serious benefits in
Wrenches,
I'm am in the initial phases of design for a commercial system in Honolulu
and I'm planning on 1000v on the DC side and I want to know if anyone has
had any issues with the AHJ on going over 600v. Any advise on designing or
installing in Hawaii is appreciated.
Best,
Max
August, it’s hard for me to see the point if you get all those benefits (long
strings, module level tracking and monitoring, design flexibility) for the same
price with micros.

Hi Bill,
That was my take up until recently. However, we’ve had lots of Enphase
failures with M190s and M210s (to Enphase’s credit, no failures yet with
M215s and M250s) so I’m hesitant to put more and more micros up on the
roof. Plus, the price starts to beat micros around a system size of 4+
No trunk cable is bonus. Working with regular PV cable is easier on stocking
materials.
Safe working voltage is real bonus and makes testing during installation
reasonable.
Strings over 12 is bonus. Sometimes, 16, 18+ makes sense physically. Now it can
make sense electrically. With different
Augustwe have a half dozen systems out thereThey are all producing
with high efficiency and no failures yetI think one advantage they have
over micro's is that your wire runs are made using 350VDC and so you can
get up to 25 modules or ~5200 watts per string ( which ever you hit
