Classic Charge Modes:
EQ MPPT - Full output trying to get to the Equalize setpoint.
EQUALIZE - Has reached the set point and is regulating to maintain voltage.
BULK MPPT - Full output trying to get to the Absorb setpoint.
ABSORB - Has reached the set point and is regulating to maintain voltage.
FLOAT MPPT - Full output trying to get to the Float setpoint.
FLOAT - Has reached the set point and is regulating to maintain voltage.
Classic and Float - 4 ways to make the Classic come out of Float:
1. Start of a new day, which the Classic does at 23:59 hours. Ensure the clock is set
correctly, or the Classic may start a new day at some random time.
2. A REBULK voltage setting will force the Classic back into Bulk mode if the battery
voltage is =< the REBULK setting for 90 seconds. Any “blip” or jump of the battery
voltage above the REBULK setting will start the timer back at 90 seconds.
3. Power off the Classic for 30 seconds, then turn it back on. It will act like it does at
sunup.
4. Forcing the Classic into Float using the “FLT” setting in the TWEAKS menu.

Charge Time
For the Absorb timer, use the formula Charge Time = 0.42 X (Bank Ah / Charge rate). For example:
1. Your battery bank total amp-hour capacity is 400Ah
2. Your charge controller outputs 65A (This is based on PV wattage / nominal bank voltage)
