Installation; Tools And Materials Needed - Go Power MPPT-PRO User Manual

STAGE 1: BULK
In quick charge stage, the battery voltage has not yet reached the set value of full charge voltage (i.e. equalizing/boost
charge voltage) and the controller will perform MPPT charging, which will provide maximum solar energy to charge the
battery. When the battery voltage reaches the pre-set value, Stage 2 charge will start.
STAGE 2: BOOST
When the battery voltage reaches the boost voltage, the controller will perform constant voltage charging. This is no
longer MPPT charging, and the charging current will gradually decrease with time.
STAGE 3: FLOAT
Float charge is conducted following the boost charge stage. The controller will reduce the charge current to a small
amount in order to prevent self-discharge of the battery and keep it fully charged. If the load exceeds this small current
the battery voltage will start to decrease until it reaches the recharge voltage. When the battery voltage falls below the
recharge voltage, the controller will switch back to bulk charging.
STAGE 4: EQUALIZE
Warning: Risk of explosion!
Equalizing vented lead-acid battery may generate explosive gases. So, the battery
compartment must be well ventilated.
Caution: Damage of device!
Equalization can increase the battery voltage to levels that may damage sensitive DC loads.
It is necessary to verify that the allowable input voltage of all system loads is greater than the
equalizing charge set value.
Caution: Damage of device!
Over charge and excessive gas evolution may damage the battery plates and cause active
substances on the battery plate to come off. Equalizing charge may cause damage if voltage
is too high or time is too long. Please carefully check the specific requirements of battery
used in the system.
Certain types of battery benefit from regular equalizing charge, which can stir electrolyte, balance battery voltage,
and complete chemical reaction. The equalize charge increases the battery voltage above standard voltage, causing
vaporization of battery electrolyte. By default, this happens every 28 days.
Note When the controller is not able to stabilize battery voltage due to the influence of installation environment or
load, the controller will wait for 3 hours (or custom value if custom battery type used) and then automatically
switch to float charge
