Abstract: Hybrid Solar Power Pack is an integrated system consisting of Solar charge controller and Grid charger. The HYBRID SOLAR POWER PACK system consist of additional SMF Battery of 12V. The Hybrid Solar power pack charges the battery with mains and Solar Both by current sharing process, giving preference to solar and DC Power Supply specially designed for other DC Power equipment. If Float charger output goes high (>14.1 V) then it disconnect the load and battery. Hybrid Solar Power pack is a DC power solution for DC equipment using both solar as well as AC mains supply. This system provide the five output port with maximum output of 12V/7A (DC) from mains and 12V/10A (120W) from solar. We briefly described the invention through images in this documents.
Description:
HSPP is a Hybrid power supply system which uses Solar Photo Voltaic power and AC
mains to charge the battery and run the DC load. It also includes high frequency Grid
charger with active power factor correction .
HSPP is an innovative as well as eco friendly, DC power solution that provides power to
Battery and external DC equipments. It is designed to install with external battery. Its
compact size and design makes it suitable to install in lesser area.
Major Components of the System :
Charge Controller UnitrThe charge controller is consist of:
(a)SPV Charge controller : The function of SPV charge controller unit is to provide DC
power supply to the load and battery & protect battery bank from over charge , deep
discharge, reverse polarity and short circuit thereby ensuring that the electrical
characteristics of the system are met for optimum performance and reliability.
(b) Float Charger (FC): The unit have an in-built float charger that provides DC power
supply to the load and battery when the AC main are available.
(c) Battery Bank: It stores the energy generated by the Float charger and SPV
charger. The battery capacity is decided by the load and the number of sun less days.
(d) Charge controller provides the isolation between the FC output and output of the
SPV power source. It also provides priority to SPV output over the FC power when both
are available.
Solar Photovoltaic Generating Module/Panel: The module consists of a number of
solar cells that are interconnected in series combination and hermetically sealed with a
toughened and highly transparent front glass cover. This module is used for charging
the batteries & simultaneously meeting the demand of load when sufficient sunshine is
available.
Communication Protocol:
• The Hybrid solar power pack have provision for 1 USB 2.0 ports for remote
control and monitoring the health of the SPV system based on various
parameters like solar voltage, solar current, battery voltage, battery current, load
voltage, load current, battery state of charge, depth of discharge, Mains voltage,
and alarm indications.
Work information:
HSPP has a provision of sharing power between Solar and grid. It will run the load
through grid power and Solar power with charging of the battery. Itwill give priority to
run the load if the input power is not sufficient. When the incoming power is such that it
fulfills the load requirement then the excess power will be used in charging the battery.
LCD Display
HSPP has user friendly LCD panel that display system parameters with battery status,
Grid charging, Solar Charging and protections.
LEDs
AC ON (Green LED): This LED indicates, when continuous glowing, AC mains is in the
required range which is 90V to 300V. It will be off when the AC input is out of its
operating range.
Battery Low (Red LED): This LED will glows intermittently when the battery voltage
becomes in the range of 11.IV to 11.4V while decreasing. It will solid glow when the
output goes off due to battery low below 11.1V.
FC CHG (Amber LED): This LED indicates, when glowing, that the battery is getting
charged or load is operating by utility grid.
Solar CHG (Yellow LED): This LED indicates, when glowing, that the battery is getting
charged or load is operating by Solar Power.
FC Fault (Red LED): This LED will glow when FC output becomes greater than 14.1V
due to MAINS charger fault OR SPV fault in the system other than Mains out of range.
SWITCH Functionality
SCROLL SWITCH: It is used to stop the automatic scrolling of the display parameters.
When we press this switch for at least 1 sec then it will hold the display to its presently
displaying parameters. To signify the hold display a symbol of @ will occur at the top
right corner of the display.
This indication shows that the grid voltage is
cut and charging from Grid is OFF.
This indication occurs when the system is
connected to the grid and load is off under
LOW VOLTAGE DISCONNECT protection
when battery voltage becomes less than
11.1V.
This indicates the status of charging through
Solar. Whenever charging occurs through
Solar and load terminal is ON then this
indication will occur on the LCD panel.
When short circuit occurs at the load
terminals then the LCD panel will show this
indication.
This indication will be displayed on the LCD
panel when FC output becomes greater than
14.1V due to MAINS charger fault OR SPV
fault in the system other than Mains out of
range.
Features:
a. Solar and Grid charging option.
b. Intelligent sharing of power between Solar and Utility Grid.
c. Prioritize Solar power over grid power.
d. LCD and LED monitoring.
e. USB 2.0 Port for Data logging.
f. Active power factor correction.
g. Eco friendly.
h. Solar Photovoltaic Reverse Polarity
Fully protection against PV reverse polarity, no damage to the system will result.
Correct the wire polarity to resume normal operation.
i. Battery Reverse Polarity
Fully protection against battery reverse polarity, no damage to the system will result.
Correct the wire polarity to resume normal operation.
j . Over Charging Voltage/Current
This device has Features to protect batteries from overcharge that can damage it by
excessive heating during overcharging. It always limits the charging voltage/current that
maintains battery health.
k. Solar high voltage & current
It will protect against high voltage of Solar panel. If mistakenly high Solar voltage (>25V)
is applied to the system then it automatically detects high voltage and rejects the Solar
power. Correct the Solar panel voltage to resume normal operation. Also, it has the
facility to limit solar power. If output power exceeds to WOW then it limits the output
current and reduces the output voltage.
I. Output High voltage and current
It will protect load against high voltage such that if output voltage reaches above 14.1V
then it will automatically disconnect the load. In over current protection, system will
turned off and it will reattempt 3 times at 10 sec interval and load disabled for 30 min. In
order to cease the load terminal to be turned off again, user have to reduce the load
connected to the system.
m. Reverse current flow at night from battery to Solar array
During night time Solar panels fetch power from battery and it can discharge the battery.
But in HSPP there is a protection to cease the power fetching from battery through
Solar panels. This will saves stored energy in battery.
n. Deep Discharge Battery Recovery
If the battery get deep discharged then HSPP has the ability to charge that battery
efficiently.
o. Load Short Circuit
This protection protects the system in condition when the load terminals get shorted. In
that condition load terminal will be turned off and retry after 30 minutes. If the short
circuit condition is not removed then this system will take 3 retries to connect the load
after every 30 min interval. After 3 retries short circuit condition remains same then load
disable permanently. To run system again, system power sources like Battery, Solar
and Mains input needs to be remove and wait for 30 sec. Now connect the power
sources again.
p. Last Discharge Cycle
This feature detects battery charge and discharge cycle in 180 days. If battery level
goes below 11.5V before 180 days then system day counting time will be reset. This
means that timer will start again. If battery level do not goes below 11.5V in 180 days
then system will switch off the battery charging until battery falls below 11.5V. This will
be repeated in every 180 days. This shows that one charge and discharge cycle for
battery is completed.
