Current developments in wave energy conversion has focussed on locations where the wave energy resource is highest; using large devices to generate hundreds of kilowatts of power. However, it is possible to generate power from low power waves using smaller wave energy devices. These lower rated wave energy converters can form arrays to supply power to remote coastal or island communities which are off-grid. The paper introduces wave-to-wire modelling of wave energy arrays for off-grid systems using low power permanent magnet linear generators. Offshore battery storage at the DC link is added to keep the voltage constant along with a direct power controller for the inverter in order to supply constant low harmonic power to the residential load connected off-grid. Results presented show that the wave energy array can generate power independently from the residential side by keeping the system stable using offshore storage. In addition, different types of controllers for wave energy devices based on the point absorber concept are compared based on the power captured from the waves
