Waterproof and Dustproof
Solar Charge Controller

IP68*Tested in water at a depth of 5m for 1 hour.

High Weather ResistanceSlim and compact design

SolarAmp BG is fully encapsulated in a special plastic
case and meets waterproof and dustproof IP68*.
IP68.* The
operating temperature range is -40°C to +70°C, which
is for use in harsh environments.

The size is as small as a business card. Thanks to noterminals, the thickness is only 8.5 mm.

High Toughness

Easy to Install and Use

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

No installation settings are required. Automaticallystart after connecting the battery, photovoltaic moduleand DC load.

Multicolor LED Indicator

Low Self-Consumption

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

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

Cutting-edge Technology

Made in Japan

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

Both software and hardware are designed and manufactured in Japan.

Adequate Protection Circuit

Over Discharged Battery Recovery·High / Low Voltage Protection·Over Discharge Protection·High Temperature Protection·Reverse Polarity Protection

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

·Over Load Protection·Short Circuit Protection·Surge Protection

3-Stage Charge

Applications

SolarAmp BG detects battery voltage and runs 3-stage
charging of bulk, absorption, and float charge automatically. The charging stage can be confirmed from the LED.

SolarAmp BG is widely used in stand-alone PV systems such as solar home system in remote area,
solar street light and measuring system.
