1.1 Product information
The MPPT Solar charge controller is a fully automatic battery charger that
converts the energy, generated by the Solar panel, into a regulated battery
voltage. MPPT stands for Maximum Power Point Tracking. Using this
technology, the charger continuously searches for the maximum
deliverable capacity or the Solar panel. This to ensure to get maximum
return from your Solar panel. This return is more than 20% higher than for
conventional systems.
This product can be connected to an external LDC display or Bluetooth
communication module.
1.2 Product properties
▪The charger has a dual-peak or multi peak tracking technology.
This will always monitor the maximum power point, if the solar
panel is partly in the shade or partly dysfunctional.
▪The charger can be set for the following types or batteries: gel-
batteries, low-maintenance batteries, lead batteries, lithium
batteries, etc.
▪The charger is protected against too high currents. In case the
capacity of the solar panel exceeds a certain level and the
charging current is higher than the rated current, the charger will
automatically assume downward adjustment and align the
charging current to the rated level.
▪High start-up currents or capacitive loads do not cause failures.
▪The charger will automatically set to 12 or 24V-DC battery
voltage.
▪The charger has a data log function. Details can be stored for up
to a year.
▪The charger has built-in temperature monitoring. When the
temperature exceeds the set value, the charging current will
linearly drop to reduce the temperature increase of the charger.

This is to prevent the charger from getting damaged by
overheating.
▪During the charging of lead batteries, in can of a temperature
increase, the charger will automatically reduce the charging
voltage to lengthen the life span of the battery.
1.3 Introduction to Maximal Power Point Tracking (MPPT)
technology
Maximum Power Point Tracking (MPPT) is an advanced charging
technology in which the solar panel generates more output capacity, due
the adjustment of the settings of the electrical module. Due to the non-
linear character of solar panels there is a maximum output capacity
(maximum power point) on the power curve. As conventional PWM
chargers do not continuously follow this point, they do not get the
maximum capacity of the solar panel. But a Solar charge controller with
MPPT-technology will continuously monitor the maximum power point to
get the maximum quantity of energy from the panel.
Take a 12V Solar system for example. The maximum peak voltage (Vmpp)
of the solar panel is approximately 17V, whereas the battery voltage is
approximately 12V. When using a conventional charger, the voltage of the
solar panel will remain around 12V, not being able to provide the
maximum capacity. The MPPT-charger solves this problem by
continuously adjusting the input voltage and current of the solar panel
continue and, as such, realise maximum input power.
In comparison with conventional PWM-chargers, the MPPT-charger uses
the maximum capacity of the solar panel and, as a consequence, it be able
to provide a higher charging current. In general, the MPPT charger is able
to increase the energy consumption by over 20% compared to
conventional chargers. A series connected panel can also be connected
with lower currents and losses.

As a consequence of the changing ambient temperature and light
intensity, the maximum power point will vary significantly. Our MPPT-
charger will adjust the parameter settings, based on the conditions so that
the system will always function close to the max. operational point. The
entire process is fully automatic.

1.4 Introduction of charging phases
The MPPT charger makes use of a 3-step charging curve for the
charging of the battery. A full charging process includes: A] consistent
current charging, B] consistent voltage charging, C] floating charging.
The charging curve as shown below:
Image 4. Charging diagram
A] consistent current (CC) charging
During CC charging, if the battery voltage hasn’t yet reached the set value
of charged voltage, the charger will charge the battery with maximum
MPPT Solar energy capacity. When the battery voltage reaches the pre-
set value, charging at consistent voltage will start.
User manual MPPT Solar charge controller PowerXtreme XS20s
E18-XS20s-EN00 www.emergoplus.com Page 10 of 49
B] consistent voltage (CV) charging
During this phase in the charging process no MPPT charging is used.
During this phase the charging current will gradually reduce. The
consistent voltage charging consists of two sub-phases, i.e. equalizing
charging and boost charging. These two phases are not executed
alternately, but equalizing is activated once every 30 days. This does not
happen in the charger is in Lithium mode.
B.1] Boost charging
As a rule, the boost charging takes approximately 2 hours. Users can
adjust the pre-defined values of duration and boost voltage point for lead
batteries to suit their own needs. When the time set has been reached, the
system will switch to floating charging.
B.2] Equalizing charging.
WARNING!
During the equalizing charging, an open lead
battery could produce explosive gas. For that
reason, the battery should be charged in a well-
ventilated location!
CAUTION!
During the equalizing charging, the battery voltage
could reach values high enough to cause damage
to the sensitive DC users. Check and ensure that
all permitted input voltages of all users in the
system are higher than the voltage set for battery
equalizing charging.
