Built-in high-frequency isolation transformer for emergencies

Even if the solar cell module is grounded due to earthquake, lightning or other event, the current from the power company’s commercial power supply side unit will not flow to the solar cell side.

Can be switched to stand-alone operation in a power failure

Even in the unlikely event of a power failure, if the unit is still in a power-generating state it can be switched to stand-alone operation to allow use of a dedicated outlet in the system only (AC100V, up to 1.5 kW).

If Sunvista should be damaged due to a sudden accident such as fire, lightning, or typhoon, repair costs will be guaranteed up to a certain limit according to the installed capacity, in the event that your fire insurance does not provide satisfactory compensation. (Low-voltage systems under 50 kW)

Ex. Up to 2.26 million yen for a 4 kW installation

Surplus power generated can be sold, and less expensive nighttime power can be stored. Stored power can be used during morning or evening time periods when less power is generated, reducing the need to purchase expensive power. Cloud HEMS supports the use, storage, and buying of energy.
