Hi Larry,
In this case, the Enphase will AC couple with the Magnum in the
protected loads panel. The AC out of the Magnum provides the micro
grid to which the Enphase connects. If charging exceeds loads, when
the grid is down, power will go to the batteries (up to the high
battery voltage set point). If loads are greater than the output of
the Enphase system, the Magnum will produce power to feed the loads.
Thanks,
Drake

Hi Drake,
If the Enphase are online, up to 60 amps (30A @ 240V) can be
transferred through the Magnum inverter to loads. The inverter is
not providing power to loads at that time. If the Enphase go
offline, the Magnum takes over using power from the battery. If the
load is greater than your Enphase system can provide, the Magnum
will transfer to battery power based on the VAC dropout setting. You
probably want to use the UPS mode (read ME-ARC manual about this).
The new Magnum MSH models can combine AC input power and battery
power to increase the total AC output capacity for starting heavy loads.

This information helps greatly. I really appreciate all of your expert advice.
One other wild card in the installation is that the inverter is
going to be AC coupled with an Enphase system. The Enphase system
will contribute greatly to the overall power available in the
protected loads panel. But, with Magnum's slow voltage response I'm
not sure if the Enphase system will drop off line when the pump
surges, or if the Enphase power will be available to help with the
startup surge.
Any insights on this?
Thank you,
Drake
