Microgreen Power Pak - Warranty Information

The table below describes common problems and recommended solutions.
Table 9.2
AC Charging Current for Power Pak Model
Symptom
Possible Cause
Recommended Solution
Power Pak will not turn on during
initial power up.
Batteries are
not connected,
or connections
are loose.
Check the batteries and cable connections.
Ensure the battery switch [11], MPPT-battery breaker and MPPT-
PV breaker [9] are set to ON. If it still will not turn on, call
Microgreen support (it may be the DC fuse).
Low battery
voltage.
Charge the battery. The battery voltage may be too low for the
Power Pak’s built-in chargers to initiate a charge. An external
charging source, such as a car charge, may be required to bring
the battery voltage up to the minimum for the Power Pak to
function.
See Section 7.2.3 for more information.
No AC output voltage and no
indicator lights ON.
Power Pak has
been manually
switched to
OFF.
Toggle the Power Pak Switch on the front of the Power Pak.
AC output voltage is low and the
Power Pak turns loads OFF in a
short time.
Low battery.
Check the status of the batteries and recharge if possible.
Charger is inoperative, and unit will
not accept AC power.
AC voltage has
dropped out-of-
tolerance.
Check the AC input source for proper voltage and frequency.
Charger is supplying a low charge
rate.
Charger
controls are
improperly set.
Adjust the charging rate using the liner switch to the right of the
Battery Type Selector on the front of the Power Pak.
Low AC input
voltage.
Ensure a qualified AC power source is properly connected to the
AC input.
Loose battery or
AC input
connections.
Check all DC /AC connections.
Charger turns OFF while charging
from a generator.
High AC input
voltages from
the generator.
If possible, turn the generator output voltage down. Alternatively
load the generator down with a heavy load, for example by
turning on a heater.
Sensitive loads turn off temporarily
when transferring between grid
and battery power.
Low voltage trip
may be set too
low to sustain
certain loads.
Set DIP SW2 to Position 0 to select a more narrow AC voltage
range or install a UPS for sensitive loads.
Unusual noise from the Power Pak.
Applying
certain loads,
most commonly
a hair drier.
Certain types of loads can cause internal components to rattle or
vibrate. This will not harm the Power Pak or connected devices.
The noise should stop when the load is reduced, for example by
unplugging the hair drier.
