Wattsun. Make sure you insert a 5 Amp ac breaker for the ps and you’ll be

<p class=MsoPlainText><font size=2 face=Consolas><span style='font-size:10.5pt'>We
are doing a tracking system and need to run a couple conductors back out from
the house to power the tracker. I suggested that we tap off of the output from
one of the AC legs of the Enphase output instead. From the inventor of the
tracker: from the manufacturer"The tracker needs 12V 10A on demand. I have
found that a small battery w/ charger nearby or AC to DC converter to 20A (for
surge) will work." These would be short surges of perhaps 4 seconds. Since
it is backfeeding onto the lines instead of powering a device, i.e. a motor
which might overheat if there is an imbalance, the only consideration would
seem to be that the frequency of the signal remain stable. Once in the bus bar
of the house panel, it would be irrelevant that there would be a temporary
voltage drop or slight imbalance.<o:p></o:p></span></font></p>
