    Sir,
    Thank you for your valuable guide.
    Sir, I want to build solar inverter for driving A.C. load of 200watt for 5 hours. Also I want to charge battery by solar as well as A.c. 230 volts But preference to solar . Since in Maharashtra now tariff rate is very high. Also load shading problems.

    Can i use to charge 12v 70ah battery?

    October 27th, 2011 at 12:08 pmTo charge 70Ah battery, you need atleast 7Amps transformer for C/10 mode.

    For my inverter transformer-primary(723turns) and sec(36). And i have 12v 70ah for the inverter. What is my transformer amps rating. If is not suitable what should i do?

    October 27th, 2011 at 3:27 pmTransformer Amps can’t be determined by counting number of turns.
    Generally 6-7Amperes transformers weight around 5Kg.

    Concerning the relay, pls explain the pins, and how to connect the pin to regulator and the output of the inverter.

    November 4th, 2011 at 4:43 pmDear Matt
    use this relay for autmation & note that the relay(shown in linked relay circuit) pin no:1 & 9 connect with circuit relay pin 11 & 21 respectivly, and relay pin no: 6 & 10 with circuit relay pin no:14 & 22,here is link which aded ….http://www.futurlec.com/Relays/GR220PIN4P.shtml

    I buy one 220vac, 12vdc. But the pins does not av number.

  • Matt on November 15, 2011 – 4:55 pm

    Tell me the function of those diode and why we use 7809 regulator not 7805 or 7812. And can this inverter charge 12v 100ah battery.

  • Mujtaba Ali on November 15, 2011 – 6:04 pm

    re check the given link,here is solution off your problem,bcoz any 220VAC relay pins are like given link relay pins…..for just 14 pin type of relay…ok

    and you have to need also to follow this link,

    that is also in your mind that when you start design inverter, for this purpose you have need re wounded tranformer,bcoz the tranformer which is available at shops can not provide require voltage when you supplied it by battery…..so you have use your own rewounded tranformer for good voltage regulation on Load……..
