Q) Can I charge my unit with a wall outlet or generator?
• A) Yes, there is an on-board AC battery charger built into your unit.
◦ There is a receptacle located on the rear passenger side that you can plug a power
supply to the battery charger.
◦ Remember to use a 20amp circuit if you're getting power from a wall receptacle.
The battery charger uses 14 amp of AC current. If you're using a generator, use at
least a 3KW (running watts) sized generator.
Q) How long does it take the AC battery charger to recharge my batteries?
• A) That depends on the depth of discharge of the batteries.
The batteries will normally recharge within 8 to 12 hrs. depending on the depth of
◦
discharge. (22vdc-24.5vdc)
If your batteries are lower, then the AC charger will take longer to charge the battery
◦
bank.
NOTE: Battery banks that are below 20vdc may be damaged not come back at
▪
all. Therefore, it is very important to keep the solar wings up and breakers on for
the solar charge controllers, even when not in use, to maintain the battery bank.
Q) What are some appropriate solar input voltages?
• A) The solar input voltage will vary depending on what stage of charging your unit
is in.
You will see solar input voltages between 80 volts to 12 volts DC. If the unit is in the
◦
sunlight, otherwise you may see much lower voltages.
It's important to note that is it's about the voltage of the solar panels but about the
◦
amperage going into your batteries.
Q) The solar panels don't seem to be charging according to the remote meter (if
equipped), no wattage showing, is there something wrong?
• A) No, the Tri-Star remote meter will only display what wattage the batteries are
expecting.
◦ Exp: one side of the solar panel is showing 113 watts, the other side pointed in the
same direction is only showing 30 watts.
▪ This is because the voltage of the battery bank is almost topped off and is only
allowing (x) number of solar panels to provide power to the battery bank.
