WARNING: Risk of Explosion
Equalizing vented batteries produces explosive gases.
The battery bank must be properly ventilated.
CAUTION: Equipment Damage
!
Equalization increases the battery voltage to levels that
may damage sensitive DC loads. Verify all system loads
are rated for the temperature compensated Equalize
voltage before beginning an Equalization charge.
CAUTION: Equipment Damage
!
Excessive overcharging and gasing too vigorously can
damage the battery plates and cause shedding of active
material from the plates. An equalization that is too
high or for too long can be damaging. Review the
requirements for the particular battery being used in
your system.
Battery Charge Settings
Preset EcoBoost MPPT battery charging options are shown
in tables 4-1 and 4-2 below. All voltage settings listed are
for nominal 12 Volt batteries. Multiply the voltage settings
by two (2) for 24 Volt batteries.
