The DeviceInfo XML returns data like this:

<?xml version="1.0" encoding="UTF-8" ?>
<info time="167C123A">
<data key="vendor" value="EnaSolar" />
<data key="model" value="1" />
<data key="acOutputVolts" value="247.1" />
<data key="pvVolts" value="354.6" />
<data key="pvPower" value="0.989" />
<data key="acPower" value="0.942" />
<data key="kWattHoursToday" value="9.35" />
</info>

We had mistakenly interpreted pvPower and acPower as amp current values, but they turn out to be kW values. The node should use pvVolts and acOutputVolts to calculate the pv and ac current values.
