Delta Volt Fuel Gauge
Q) My fuel gauge shows my battery capacity in the RED for several days in a row.
Is my unit charging?
• A) YES, once your fuel gauge enters the RED it will not move back up the LED line
till your battery voltage reach's 26 volts.
• If your unit is working 7 days a week and you're in the Fall Winter months, it's hard for
the SLT units to recover enough solar input in one day to get the battery voltage above 26
volts. Read the user manual on the delta-volt for more information on LED color code.
◦ The new delta-volt fuel gauges reset themselves every 7 mins to give the customer a
better accurate reading of battery capacity.
