<div dir="ltr">True, but I don't think I'd want to risk the batteries and rely on customer load management. And it seems like energy management mode (according to the manual) should do what I want, so the lingering questions are:<div>

Expanding on William's suggestion, you might also consider a
conventional 240V time switch on the AC1 input, to limit the times
when grid charging might occur. The inherent limitation of this
approach is that it while it would effectively prevent charging
during peak hours, it would defeat allowing the grid to charge
when really needed, so the owners would have to pay more attention
to their usage habits. This may not be so bad, as it would only
affect short-term usage and would not depend on weather patterns
varying the solar insolation.<br>

LBX can have the unintended consequence of charging during
peak hours if the loads draw the batteries down during that
time. This can be avoided if you can control the loads so
all or most do not operate during peak hours.<u></u><u></u></span></p>

The obvious logic is that if you can control the loads to

<p class="MsoNormal">Thanks, I was thinking about using LBX,
but the customer is really not too excited about it. And
based on the manual, Energy Management Mode seems like it
fits the bill, but it doesn't seem to be going back into
stand-alone/inverter mode when the timer is supossed to turn
off.<u></u><u></u></p>

<span style="font-family:"Arial","sans-serif"">Hi
Brian,</span> <br>
<span style="font-family:"Arial","sans-serif"">LBX

the grid when the batteries get low. Unfortunately, the
