800Va Home inverter charging

[nicolethomson]

Hi board members,

I have a 800Va inverter from local vendor, so far it was getting charged over my home Power connection from EsComs,

if it has to get charged with Solar panel also, whatwould be the requirement from

1. Solar panel output,
2. any circuit tobe added/ changed in Inverter?

can someone please guide me,

You should look the voltages. wich gives you Solar pannel. If the voltages are the same, you can try to connect it directly. Or with diodes.

The best way to charge your batteries using solar panels is to use ''solar charge controlers''their are pwm charge controlers in the market you can get one or you construct it.

any specifications on pwm charge controllers i need to check ?

like 5A or 12A, i willbe using 100Ah

also

can i add 2.5Ah 12V battery and 10Ah 12V battery in series, to get 24V? in that case what will be the Ah?

If you to construct your own then following link is useful.

Effectively 2.5AH for 24v. They need to be the same AH rating, not good mixing it this way.

When battereies are charged through solar pannels, it is suggested to verify that the pannel is capable of delivering at least 10% of the capacity of the battery. Mean if your batterey is 100ah, the panel is ecpect to be atleast of 10ah for better performance. A solar charge controller is used in between the pannel and the battery. If you choose to charge the battery by solar, disconnecting your regular charger will be the best idea and vice versa.

thanks pranam77,

i am going back to the basic's, if we buy a 100Watts solar panel, this will produce 100watts/sec in bright sunny day? in this case 100Watts X 60 sec x 60 mins?

could it be correct

 

[pranam77]

Wattage is usually calculated per hour. Having a 100 watt pannel, with 12 volts means it is capable of delivering Approx 8 amps of current @12 volts per hour. But naturally it is a means of mesurement, and this will vary from pannels and the light conditions where it is placed...Cheers

that is awesome answer dear pranam77.

thanks a lot.
