Summary:During islanding conditions, two or more on/off GTIs will work stand alone, these inverters can't work in parallel, because there is no parallel mechanism in this inverter. So power absorption from PV not reach maximum and battery power drain. To make these inverters can work in parallel we must add a power limiter in input inverter using chopping/PWM method and this is not cheap. This research proposed method to parallel two inverter using reconfiguration of Photovoltaic (PV) circuit on microgrid based on/off GTI inverter, in islanding condition, using master slave parallel network topology inverter. The test results showed paralleling two inverter can be done using reconfiguration of Photovoltaic (PV) circuit and increase the absorption of energy from PV up to 26% and reduce the use of battery backup up to 26.38%, so the level of the battery can be sustained.
