INSTALLATION & OPERATION

SURYA-40 HV VERS.7

1. PV Panel Grouping: Group the PV panel array using standard Solar MC4 connectors and parallel connectors as to the recommended grouping example chart provided. Good quality weather proof solar DC cables must be used (4sq,6sq,10sq).
2. Battery Bank Setup: If more than one battery is used, Connect the batteries with 16sq.mm/10 sq.mm interlinking cables and tight them well. Check each battery separately for specific gravity, same terminal volt and good backup. Do not use old and new batteries together, either in parallel or in series
3. MPPT Charge controller installation: Mount the MPPT charge controller vertically on the wall using the wall mounting clamp provided. It is better to isolate MPPT from the wall , mounting it on a PVC board (kitchen cutting board) in order to avoid lightning hazards and earth leakage problems.

❌Avoid exposure to rain, dusty area, direct sun light or in area having high temperature
✔ Use 25 sq.mm/16 Sq.mm standard electric cables below 1.5 meter length as battery wires, red color for positive connection and black for negative. Remove the connection terminal cover of the charger. and connect the battery wires with correct polarity to the desired battery bank (Reverse polarity will spoil the charge controller)

Three LED Indicators and cooling fan of the device starts functioning for 5 seconds and goes off.
MPPT starts scanning connected battery bank. Display shows the voltage of the connected battery bank and applicable range of PV Panel Open Circuit Voltage (Voc) limit for the connected battery bank. Ensure the displayed battery bank voltage and connected battery bank voltage is same when MPPT is powered on. (12V/24V)

Connect the cables from PV panels to the solar positive and negative terminals of the charge controller. If the panel voltage and polarity is correct green LED indicator glows on. When the PV Panel voltage detected is higher than the connected battery bank voltage MPPT starts charging.
When the PV panel voltage goes below the battery bank voltage the green LED indicator goes off. When the device detects more than 2Amp charging current to the battery, charging LED (RED) glows on.

If the current is less than 2Amp the Red LED goes off ,but charging continuous in low amp till the solar power availability.
When the connected battery voltage reaches 14.2V (adjustable) the Blue LED glows on indicating battery is near full charge (default value 14.2V) and ready to use load either directly from the battery or through an inverter.

Automatic Grid power/ Solar Power Change Over using MPPT charge controller
(Converting a Home Inverter to a Smart Solar Inverter – Solar Management Unit – SMU )

Remove the connected grid phase input wire from the the inverter and connect to the ‘PHASE IN’ terminal on the charge controller.
Connect another wire from the ‘PHASE OUT’ terminal of the charger to the input phase connector of the inverter.

Automatic Solar to Grid / Grid to Solar change over function
In default mode MPPT charge controller is in AUTO BYPASS ON mode.
When it is in OFF mode press and hold ( ) UP button on the front panel for 2 seconds.

What Happens If Auto Bypass Mode Is In ON Position:
✔ MPPT disconnects grid power to inverter when the battery voltage goes above GRID-SOL set voltage
(default 14.2V/Battery). MPPT display shows INV MODE ON , AUTO BYPASS ON and LOAD ON SOLAR LED (Blue) glows on.
✔ MPPT connects grid power to inverter when the battery voltage goes below SOL-GRID set voltage
(default 11.5V/Battery).MPPT display shows INV MODE OFF , AUTO BYPASS ON and LOAD ON SOLAR LED (Blue) goes off.

To turn off automatic bypass function in MPPT press and hold ( ) Down button on the front panel for 2 seconds.

When Auto Bypass Mode off :
✔ MPPT reconnect grid power to the connected inverter. MPPT displays shows INV MODE OFF , AUTO BYPASS MODE OFF.
In this mode inverter will be always on grid power.

What is Forced Grid to Solar Shifting
When a heavy load is applied on inverter when running on solar mode (eg;- iron box, pump set, normal fridge, etc.) a sudden voltage drop will make MPPT to shift from solar mode to grid mode. It will only be shifted to solar mode the very next day when battery is fully charged .If the battery terminal voltage is above the solar to grid change over set voltage (default 11.5V) inverter load can be shifted again to solar mode by pressing and holding (⏺ ) ENTER button for 3 seconds.

How MPPT charger controls the connected Inverter:
Charge controller is provided with a relay inside to connect and disconnect grid power to inverter monitoring the terminal volt of the battery. When the battery terminal volt rises up to 14.2V (adjustable) charger disconnects Grid power to the inverter and the load on it starts running on battery power (solar power). When the solar charging current stops load will be working from the battery bank and the battery voltage goes down. When it reaches 11.5V (adjustable) the device reconnects AC mains (grid power) to inverter and the blue LED goes off. Blinking of blue LED indicates low battery bank voltage. ie. below 11.7 V (adjustable) giving warning indication to remove heavy load on inverter

IMPORTANT NOTE FOR ACTIVATION OF LIMITED
AMPERE BATTERY CHARGING AND EQUALIZATION CHARGING

1. What is initial limited ampere charging in MPPT charge controller ?
   Maximum recommended charging current for a solar C10 inverter battery is up to 20% of the battery AH. Batteries used in solar power system is often discharged below 11.5V every day. So it is recommended to start initial charging with limited ampere instead of charging with maximum capacity of MPPT charge controller.
   Eg: Recommended maximum charging current for a 12V,150AH lead acid battery is 30 Amp. If such a battery is connected to the MPPT delivering above 30 amps the excess ampere entering the battery can be controlled in the initial charging stage by activating initial limited ampere charging feature. MPPT delivers only 20% of the battery Ah. ie.30amps to the battery

2. Ampere Limiting based on load shifting voltage:
   (grid to solar shifting volt) In this mode battery charging ampere is limited in the initial stage .(if battery is 150Ah charging current will be limited to 30 amps.) When load is shifted to solar, entire ampere is shared between load and battery.

3. Ampere limiting based on Charging mode :
   In this mode also, battery charging ampere is limited in the initial stage and the limitation is stopped after the completion of bulk charging stage. (when float charging starts) ie. The entire charging current is never delivered to battery in float charging mode as the battery is already charged to float charging level.
   MPPT charge controllers are sun light dependent devices and they can’t deliver high ampere in the morning. They start to charge the batteries in low ampere early in the morning. As the terminal volt of the battery increases, charge controller shifts the connected inverter load to solar power and the current is shared to load and battery charging. Hence the activation of limited ampere charging is not necessary in low ampere charge controllers connected with high Ah batteries.
   eg: If the charge controller delivers more than 30amp current in starting stage and the connected battery is below 150Ah it is recommended to activate limited ampere charging option.

4. What is Equalization charging in MPPT charge controller?
   When a lead acid battery is left in a discharged state for extended periods of time, non-removable sup hate crystals are formed on the surface of battery plates that reduce the charging and discharging capacity of the battery. Equalization charging is an over charging process of lead-acid batteries above their recommended charging voltage, to remove solation and bring all cells of the battery to similar levels by increasing the voltage to 2.50V/cell, or 10 percent higher than the recommended charging voltage. Equalization charging also equalize acid stratification, a condition where acid concentration is greater at the bottom of stationary batteries than at the top level. Battery experts recommend periodic equalization charging to keep the batteries healthy (once in every three month)
   SMF, VRLA, AGM, GEL Batteries.
   SMF (sealed maintenance free), SLA (Sealed lead acid) and VRLA (Valve regulated lead acid) batteries are same. Its 2 types of cells are (AGM (Absorbed glass mat) and GEL cells. They are maintenance free batteries which do not require regular water filling, its composition of electrodes and electrolyte is same as flooded lead acid batteries. These batteries do not need to be kept upright as the electrolyte is in the form of gel or paste.)
   Un-attended equalization charging of battery is risky as there is chance for overheating of battery plates, overflowing of electrolyte and damaging of batteries.
   Remove all loads from the batteries before starting equalization charging. Fill all the battery cells with distilled water in the required level. It is better to remove the all the lids of batteries before starting equalization charging as the batteries will begin gassing and bubbling vigorously at the peak stage of boost charging. Ensure the batteries are installed in a good ventilated area. Even a spark from a metal cutter, loose contact of battery wires may cause fire hazard and explosion of batteries. During equalization charging, check the changes in the specific gravity of acid of each cells every hour and stop charging if the gravity and voltage of cells no longer rises during the gassing stage. Further improvement of the cell is not possible and continued charging will spoil batteries
   Enabling limited ampere charging in MPPT charge controller.
   Enter settings menu 13. AMP-LT (Read page 10 for MPPT function settings)

5. Select option “0” to disable limited ampere charging.

6. Select option “1” for limited ampere charging up to the set value of 7th menu. (7.GRD-SOL) ( Grid to Solar shifting volt 14.2V default) When kept in this mode MPPT delivers only 30 amps of continuous charging current to the battery if the Ah is set to 150 and delivers the maximum available ampere to load and battery charging after shifting to solar power.

7. Select option “2” for limited ampere charging up to the set value of 2nd menu. (Bulk charging limit. 14.8V default) MPPT delivers only 30 amps of continuous charging current to the battery if the Ah is set to 150 and release the ampere limit only after the completion of bulk charging (14.8V in default). In this mode, load is shifted to inverter only after starting float charging (end of bulk charging)
   Enabling equalization charging in MPPT charge controller.
   Enter settings menu and configure menu 5.N-DAYS “0” to disable all modes of equalization charging.
   Enter settings menu and configure following settings for enabling equalization charging:

8. EQLZ-V : Set the equalization voltage
   As the equalization is an over charging process, ask a battery expert before setting the maximum applicable upper voltage limit. Blind settings will spoil the batteries.

9. BVLC-V : Select the battery low voltage level to enable equalization charging based on battery terminal volt. (Configure a value slightly less than inverter low voltage cut off to avoid frequent equalization charging)

10. N-DAYS : Set period of Equalization charging

    • N-DAYS = 0 =>Disables all modes of Equalization charging
    • N-DAYS = 1 =>Equalization charging starts every alternate days
    • N-DAYS = 2 =>Equalization charging starts every 2 days
    • N-DAYS = 30 => Once in a month (Recommended)
    • N-DAYS = 90 => Once in 3 months
    • N-DAYS = 180 => Once in 6 months

11. AMP-LT : Recommended to set AMP-LT “1” or “2” for controlled (limited ampere) charging to battery in Equalization charging mode. This option is recommended because system will not shift from grid to solar till the equalization charging is completed which helps to rise battery terminal voltage gradually and attains maximum gravity of electrolyte and gets good backup from batteries.

Changing the default settings of MPPT charge controller
Note: Before changing the default settings values of the device, ensure the maximum ampere and voltage ratings applicable for your battery type and brand (SMF, LEAD-ACID, GEL) This device is not designed for direct charging of lithium Phosphate battery . Blind settings may cause severe damage to the batteries and charge controller. Default values given are for lead acid C10 grade solar batteries. To reset to default settings enter settings menu 14 F-RST and set the value to “1”.(Refer user manual function settings page)

Refer battery user manual for recommended charging ampere and voltage for the connected batteries.
Never try to change the default settings of the device without the help of technical advice. Note down the default settings of the device before changing. Read function settings page before changing default settings of the device.

CONVERTING A NORMAL INVERTER TO A SMART SOLAR INVERTER
USING MPPT CHARGE CONTROLLER
Before starting it is better to make a plan of your solar energy needs and ensure your existing inverter and batteries are suitable for solar application. When a battery is charged with limited charging ampere (6AMP to 10AMP ) for long hours it delivers good energy backup. Solar charging and discharging is a daily process with high current from solar panels. We get only 4 to 5 hours average sun light in a day and have to charge the batteries in this time. C10 grade solar batteries above 100 Ah have the capacity to handle high current charging and discharging. Usually inverter batteries are either C20 grade or C10 grade normal batteries. An inverter battery is always connected to grid power and continuously charging the batteries in limited ampere for long hours (6AMP to 10AMP) and gives good back up. That is why we don’t get enough backup from normal batteries when charged from solar power with high current. If we use normal batteries for solar charging with limited charging current they can’t be got fully charged before evening. So always insist on C10 grade solar batteries for solar applications. Now check your home inverter is provided with a grid charging ON/OFF switch. Most of the branded normal type inverters are not provided with a grid charging ON/OFF switch on them. When we use this type of normal inverter in solar off-grid system it will charge batteries from grid power and we do not get actual solar benefit.

HOW THE CHARGE CONTROLLER DRIVES THE CONNECTED INVERTER
Most of the SMU type solar MPPT charge controllers are provided with an inbuilt relay to control grid power to the inverter. Remove grid power phase wire from your inverter and connect to PHASE IN terminal of MPPT. Connect a wire from the PHASE OUT terminal of MPPT to the PHASE IN terminal of the inverter. (Never connect the neutral wire of grid power to any connectors of MPPT). When charging starts terminal volt of the battery rises to the preset voltage 14.2 V (this value is adjustable) MPPT disconnects the AC mains to the inverter and the connected load on the inverter works on battery power (solar power). when the battery terminal volt goes down (in the evening or cloudy sky) and reaches 11.5 V (this value is adjustable) MPPT reconnect grid power to the inverter. If your inverter is a normal type without a grid charging disabling switch it will charge the batteries and we don’t get the solar benefit. To overcome this it is better to limit the load on the inverter and keep the battery terminal volt always high. Some customers use solar power only in the daytime and shift the load to AC mains by keeping the shifting to AC mains voltage 12.0 V or more. Fitting an external grid change over the relay system for bypassing grid power directly to load is also applicable. If we use an inverter with a grid charging ON/OFF switch we can keep the switch in off position to avoid charging from the grid. Only on cloudy days we can keep the switch in on position and charge the batteries from grid power.
