High Weather Resistance

SolarAmp BG is fully encapsulated in a special plastic case and meets waterproof and dustproof IP68*. The operating temperature range is -40°C to +70°C, which is for use in harsh environments.
*Tested in water at a depth of 5m for 1 hour.

Slim and compact design

The size is as small as a business card. Thanks to no terminals, the thickness is only 8.5 mm.

High Toughness

The housing by impact resistant special plastic and fully encapsulated structure prevent mechanical failure from in breaking of foreign body. Outdoor rated, connecting wires prevent terminals from rusting.

Easy to Install and Use

No installation settings are required. Automatically start after connecting the battery, photovoltaic module and DC load.

Multicolor LED Indicator

Green, yellow, and red, three-colors LED indicates charging status, warning or error.

Low Self-Consumption

The low self-consumption current brings long-term stabilization and increases system performance.

Cutting-edge Technology

SolarAmp BG utilizes the most advanced materials and components in Japan; achieving excellent durability and reliability.

Adequate Protection Circuit

• High / Low Voltage Protection
• Over Discharge Protection
• High Temperature Protection
• Reverse Polarity Protection
• Over Load Protection
• Short Circuit Protection
• Surge Protection

Over Discharged Battery Recovery

SolarAmp BG has the battery recovery function. This is convenient for the system in areas where systems are difficult to maintain on a regular basis.

Made in Japan

Both software and hardware are designed and manufactured in Japan.
