Pure sine wave inverters produce a wave shape identical to the electricity grid, so can power any 220V AC device.
Suitable for powering PCs, TV, radios, hifi, phone charger, and other electrical appliances. They are not recommended for appliances such as fridges, washing machines, microwaves, neon lights or inductive loads such as pumps.
Suitable for use in grid connected systems, with the certifications required in order to access tariffs of the "Conto Energia"
Inverters with integrated storage, which allow you to build photovoltaic plants grid-connected, store excess energy for night use at and sell the surplus to the grid with net metering
Integrated systems which can handle photovoltaic and wind energy, building up self-produced energy in batteries. They include pure wave inverter, charge controllers, switches and protections.
