This document introduces AC power backup for disaster evacuation shelters and similar facilities using inverter-type independent power sources. It includes information on AC power backup operations using SC inverters and examples of AC power backup configurations with the SC2000 inverter. During disasters, evacuation shelters (such as community centers) require a minimum AC power supply for lighting, smartphone charging, and disaster prevention equipment, even when commercial power is out, making independent power backup desirable. For more details, please download and take a look.

The SC series is an inverter that incorporates a battery charger into a pure sine wave inverter. During a power outage, the AC bypass circuit automatically activates, instantly starting the inverter and continuously supplying power to the electrical devices connected to the AC output. Depending on the settings, AC switching can also be prioritized for the inverter. It can also be used as an emergency power source during disasters at business locations. 【Features】 ■ Built-in battery charger in a pure sine wave inverter ■ Charges the battery while AC power is available ■ AC bypass circuit automatically activates during a power outage ■ AC switching can be prioritized for the inverter based on settings ■ Usable as an emergency power source during disasters at business locations *For more details, please refer to the PDF document or feel free to contact us.

The "BA-100" is a battery analyzer that displays a comprehensive evaluation of the battery based on the measured data. It’s a battery that has been used for a long time. You cannot determine its current condition or when it should be replaced just by looking at it. Deterioration and overcharging can lead to malfunctions and failures, so it is necessary to accurately understand the condition of the battery. This product can measure not only the voltage but also the CCA value, CA value, internal resistance, deterioration state, and charging capacity of the battery. 【Features】 ■ Measurement of Cold Cranking Amps (CCA value) ■ Measurement of battery deterioration state ■ Measurement of Cranking Amps (CA value) ■ Measurement of battery charging capacity ■ Measurement of internal resistance *For more details, please refer to the PDF document or feel free to contact us.
