STEP 11
Turn on the 72V 900W AC/DC power supply. The MPPT
charge controller will show PV input is active and the batteries will start
charging after 1
-
2 minutes. When the AC/DC power supply is charging,
both LED will be red and the unit fan will come on. This is normal. When
the batteries are fully charged the 72V 900W charger will go into
standby mode and one LED will turn green.
STEP 12:
The enclosure comes with a thermostatically (45C) con-
trolled 24/48V ventilation fan. Connect this fan directly to the batteries.
Note: Please see the MPPT solar controller user guide for addition-
al details.
TECH CORNER
Additional Information you may find useful
Solar Ready:
The system is solar ready. You may need to add a
100V 30A blocking diode (Tycon pn 5600059) between the solar pan-
el and the PV input to avoid reverse current from the 72V AC/DC
power supply going back into the solar panels.
Batteries:
The batteries are maintenance free and should last over 5
years in normal operation. The charge controller will automatically do
a balance charge on the batteries periodically.
Enclosure:
We recommend making extra keys in case the enclosure
keys are lost.
