New Proposal of Dual Power Supply Source for Rural Stand Alone Solar Photovoltaic Home Electrification System in Malaysia

Abstract:

Most of renewable energy electrification systems in rural residential area in Malaysia are benefitting the solar PV (photovoltaic) system. The initial 24V_DC voltage generated by the modules are converted and inverted to 240V_AC to replicate national utility grid standard. However indeed most modern connected loads and electrical appliance are operable within DC voltage internally which requires no extra conversion or inversion at all. Nevertheless when the AC voltage from the grid once been connected to the system, the early PV modules seemed to be totally forgotten and abandoned. An energy conservation concept has been disrupted. A new strategy of benefitting both available DC power and AC utility grid was introduced which could be implemented to save energy and optimised the whole system. Throughout design concept has been proposed and discussed.
