Wrenches,<br>
Very seldom do inverters in off grid systems ever go to sleep
anymore, given the increase in phantom electronic loads and greater
customer expectations. Coupled with lower module prices, we usually
size larger arrays and inverters remain on continuously. However, we
also service and upgrade many existing systems, and some customers
still want their inverters to go into search mode. They typically
either have gotten used to a more energy frugal lifestyle over many
years, or (to their credit) choose to buck the system and live with
a lighter energy and resource footprint. <br>
<br>
Twice in recent months we have added Midnite MNSPD MV surge
arrestors to the AC output of smaller systems and discovered that
the inverters will no longer go into search mode. It doesn't appear
to make any difference where the search watts threshhold is set. One
system used a 24V Outback FX2524T (with current boards following a
nearby lightning strike) and the other used a Magnum MS2812. In the
former case, we defeated the search (against the customer's
preference, as she liked the total silence once her day was done).
In the latter, the customer rejected and we removed the surge
arrestor once it became clear that the inverter wouldn't sleep.<br>
<br>
Has anyone else experienced this? Is there a fix for it? Robin, can
you chime in here (off list if necessary; I'll carefully post your
response)?<br>
<br>
Thank you,<br>
Allan<br>
