c. Set Float volts = 40V
d. Set REBULK = (Voltage you want to start back charging, must be > 40 Volts < 52
Volts
2. The Classic will report BATTERY OVER VOLTAGE and will stop charging (RESTING) until re-
bulk voltage is reached.
Skip Days – This setting forces the Classic in to Float at the start of the charging day vice in to
Bulk. Useful if you have an unattended system, say at a remote cabin, one that you do not
frequent often, and you do not need the solar system charging fully every day.
Limits
Output Amps – This setting limits the Classic’s output amps. Useful if your system produces more
current than your battery manufacturer recommends. Also useful if you installed a circuit
breaker between the Classic and the battery bank that is too small for the current load, and you
want to stop nuisance tripping of the breaker. Say your system outputs 80A yet you installed a
63A breaker and it keeps tripping. Change the Output Amps to 63A until you can replace the
breaker with the correct size.
Input Amps – Limits the incoming amps from the PV array. Usually not needed.
Max and Min T-Comp Vs
1. MAX - Leave at default. Only change if cold battery offset increases voltage to where
inverter shuts down from HI BATT. If so, cap it so inverter stays on.
2. MIN – Leave at default. If the battery is hot enough to make it drop too low, there will be
bigger issues to deal with.
Mode Menu
Solar – Default mode for most all solar systems. Classic sweeps the IV Curve in 0.5 seconds or
less and will re-sweep at a user-adjustable interval (Mode/Solar/Setup), normally every 3
minutes or sooner if the Classic determines a new sweep is necessary.
Wind Track – Used with wind turbine operations. Select a preprogrammed wind curve or create
your own. The wind curve consists of 16 steps along the curve, defined in terms of a voltage and
a current at each step. Best to start the curve at 2V higher than your nominal battery bank
voltage. For example, with a 24V bank, Step 1 of the curve will have a voltage setting of 26V and
0A.
Hydro – Used with a micro hydro system or other varying voltage DC inputs. Hydro mode has
two user-selectable settings: Sweep interval in minutes and Sweep Depth in %.
