Hello sir, I have a 1000W solar inverter, when i connect my battery it causes a short circuit to the battery thereby producing a burning smell from the battery terminals(wires). Aqib, try checking the stage which is responsible for activating the relay, it could be an opamp which is configured to sense overload and could have gone faulty and might be causing the relay to trip…therefore locate this opamp or whatsoever stage it may be and check the reason behind its malfunctioning, and possibly replace the faulty part with a new one…. If yes that would mean your oscillator stage is OK and the mosfets would oscillate normally allowing the inverter to work normally, that would imply your fault light stage has some probelms, you can diagnose this by checking the signal source which may be causing it to incorrectly trigger, or you may temporarily isolate this stage entirely and then check whether the inverter now starts working or not…. that clearly indicates that your mosets are short circuiting the battery, or the mosfets are not oscillating. Please clarify this point, once I understand this I will try to sort out the problem for you. DC is a relatively stable and positive voltage source and AC oscillates around a 0V base level, usually in a square or sinusoidal fashion. Indoor Status = Off, Error Code = 07 Hello Kapil, if the inverter runs normally after sometime, then the battery may not be the problem, the problem could be somewhere in the inverter.
