Inverter is just an electrical device that convert AC voltage to DC voltage during charging and vice versa during discharging ( usage). Step to increase my inverter life span.....
* Use 80 % of the rated load of the inverter.
*off all electrical appliances you are not using
* Automatically isolated loads that won't be connect to the inverter.
* keep in a well ventilated place.... Because inverter is a room tempt. Device.
* Avoid short circuiting........

Ok

How can I form the solar panels array.
First is to know the open circuit voltage of the charge controller and each solar panel, next is to know the maximum current of the charge controller and each solar panel.
To connect solar panels in series, you need the open circuit voltages. For example is a solar panel is rated Voc= 35.5( open circuit voltage) and Imax= 9.02 A. And the charge controller is rated ( nominal voltage =48V, Voc=125V, Imax=45A)
Number of panels in series ( 125V/35.5v = 3.5211) ....take the whole number = 3
That is only 3 can be connected in series.(NB: series voltages are additive)
To connect in parallel, use 80% of your rated charge controller current ( 80% of 45A =36A)
Number of the string in parallel = 36A/9.02A= 3.9911=4.
The array is panels is 3 by 4 ......

Any inverter with mains of >= 200V can charge 200 AH batteries connected in series or parallel. If your mains is low, you need a stabilizer

Practically Charge controller is connected between solar panels array and batteries.

Charge controller is to control the amount of charges entering the batteries from the solar panels array.

Batteries are storage device for storing electrical energy from solar array in volt-ampere hour(V*AH or WH, since V*A=Watt(W)

Solar panel array convert sun radiation directly to electrical energy.

"Matching charge controller with batteries."

The first thing to consider is the nominal voltage of the system. I.e the normal voltage of the series connected batteries to store energy. For 4 batteries connected in series with 12V each, the nominal voltage is
4*12 = 48V,
Therefore, you need a charge controller with nominal voltage of 48 V.

"Matching charge controller with solar panel array"

Solar panels array is a combination of solar panel connect in series and parallel

Two or more solar panels connected in series is called strings of solar panels.
Strings of solar panels connected in parallel is called array of solar panels.

From elementary Physic, parallel voltages are equal, while series voltages are additive.
Also series current are the same, while parallel currents are additive..........

This elementary rules will enable us form the solar panels array

Maintenance of inverter batteries:
Inverter batteries are deep cycle AGM or GEL batteries.
These batteries are room temperature batteries. Therefore to increase the life span of your batteries you must.....
1.Ensure its below ROOM TEMPERATURE
2.Ensure the batteries terminals is tight
3.Ensure the batteries are well ventilated
4. Don't over load your battery
There are different types of deep cycle batteries * 100 AH. 150AH, and 200AH
For a load current of 10 amperes (A)
100AH will last 10 hours while 150 AH will last 15 hours and 200AH will last 20 hours....

Congratulations. The list will come out soon.
