SunSaver MODBUS Specifications

EV_eq [57352][0xE007](V). Equalize voltage @ 25ºC, bank 1
EV_eq2 [57365][0xE014](V). Equalize voltage @ 25ºC, bank 2
Battery equalize voltage. Periodic equalization equalizes cell voltages, bubbles the electrolyte, and helps
prevent sulfation of the battery. See diagram A.
Set to zero to disable equalization
Et_eqcalendar [57353][0xE008](days). days between eq cycles, bank 1
Et_eqcalendar2 [57366][0xE015](days). days between eq cycles, bank 2
Specify the number of days between equalizations. Equalizing on a calendar basis ensures proper
maintenance of batteries.
Et_eq_above [57354][0xE009](seconds) equalize time limit above Vreg, bank 1
Et_eq_above2 [57367][0xE016](seconds) equalize time limit above Vreg, bank 2
Equalization will timeout after the specified number of seconds above PWM regulation voltage. If the
battery is charged above absorption voltage but has not yet reached the equalization setting, this value
serves as a safety timeout to prevent partial equalizations for extended periods of time. See diagram A.
Et_eq_reg [57355][0xE00A](seconds) equalize time limit at Veq
Et_eq_reg [57368][0xE017](seconds) equalize time limit at Veq
Equalization will stop after the specified number of seconds at the equalization setpoint voltage. See
diagram A.
Charging Settings (shared)
EV_tempcomp
[57371][0xE01A](V/C). temperature compensation.
Battery chemistry changes with temperature. Temperature compensation coefficient specifies the
amount that regulation voltage will be shifted with temperature. 25ºC reference, the negative is implied
(write a positive value). 12V lead-acid battery temperature compensation is approximately 0.03 V/C
EV_hvd
[57372][0xE01B] High Voltage Disconnect @ 25ºC
Flag a fault/alarm if the battery voltage exceeds this setpoint. Also attempts to open the MOSFETs to
stop charging. Set to zero to disable HVD
