Solar Charge Controller

Japanese Patent Applied 2013-035410

O ver Discharged Battery Recovery

T he World's Lightest & Compact
SolarAmp B is the lightest controller in the world. Theappearance is just as a business card and beautiful, so thatyou could make your control box smaller.

SolarAmp B has the battery recovery function. This isconvenient for the system in areas where routine
maintenance is difficult.

S imple Installation

N ight Lighting Control Function

SolarAmp B is very simple to use. Do not need any setting.
SolarAmp B turns on the light from dusk to down
Just connect to photovoltaic module, battery and DC load.
automatically. This function is appropriate with solar
lighting system such as solar streetlights and solar
gate lights.
ow Self-Consumption

LThe self-consumption current of SolarAmp B is about
2mA. This contributes to the long-term stabilization andperformance increase of your PV systems.

R ich Protection Circuitry
