Wakeup As the PV open circuit voltage (Voc) rises above the battery system voltage by two volts, the
MX60 prepares to deliver power to the batteries. During this period, the MX60 is calculating the pulse
width modulation (PWM) duty cycles, turning on power supply voltages in the proper sequences, and
making internal calibrations. At wakeup, the MX60 closes its relays and then starts sweeping the input
voltage (the “initial” sweep) towards the battery voltage. At dawn and dusk this may happen many
times until there is (or is not) enough power from the PV array to keep going. Wakeup is also a time
when the MX60 acquires a new Voc.
Zzzz... At night (3 hours of Sleeping) the MX60 will display Zzzz... until the next wakeup. At the next
wakeup, (usually the next morning), the daily statistics, (AmpHours, KWh, etc.), will accumulate into the
total statistics and then the displayed daily statistics will clear. A Bulk charge will automatically initiate
at the next Wakeup.
