In summary, Panasonics HE-V relay is a miniature power relay that can conduct and cut off high DC voltage or high currents. The LF-G relay is ideal for small sized inverters due to a large contact gap, high insulation resistance, and high surge breakdown voltage. The HE-S relay is a miniature high capacity 2FormA relay that features an auxiliary 1FormB contact. PhotoMOS ICs are used for monitoring storage battery units for insulation deterioration and for monitoring the charging voltages of a battery cell group.
