1. Introduction

Thank you for purchasing

solar charge controller. Thismanual contains important safety, installation and operating instructions
for5-3：Explosion hazard

4. Precaution

solar charge controller in order to prevent the users

from any damage. Make sure to read all of the instructions and cautionsin the manual before beginning installation.
< Battery type >Please use 11.1V lithium-ion secondary battery. The battery may beequipped with protection circuit. Depending on the protection circuit,SolarAmp B and your battery may work incorrectly. Please check thespeciﬁcation of the lithium-ion secondary battery or conﬁrm with thebattery manufacturer before using SolarAmp B .

5-4：Mounting direction

・ Cover the PV panel (Photovoltaic panel: Solar panel) with cloth not togenerate electricity during installation.
・ It is recommended to install an external fuses (less than rated current)
between controller and battery, controller and load.
・ Connect battery to earth ground if necessary (positive earth ground). If youneed negative earth ground, connect only one terminal(battery or PV panelor load terminal) to the earth ground.
・ Do not connect device which has big input capacity such as DC-AC
inverter to the load terminal.
・ Do not use PV panel or Load which speciﬁcation is out of the ratings.

Non-invertible

5-5：Positive earth ground・ Charging will start when PV panel voltage exceeds battery voltage.
・ Reverse Polarity Protection and Over Load Protection is not eﬀective inevery possible condition, thus please take care in wiring and conﬁrm thespeciﬁcations of PV panel and Battery and Load.

< Battery charging operation>• SolarAmp B charges the battery with PWM constant voltage
charging.
• Pre-charge function charges the battery with PWM at a 10% duty
cycle from LVD till the battery voltage raise to 10.0V.
• In bulk charge status, the battery is charged by the maximum output
current from the PV panel• In absorption charge status, SolarAmp B charge the batteries withPWM constant voltage charging, not linear constant current charging.

is very compact design and very simple to use, which has
full electronic protections.

Flashing: The load current exceeds the maximum load current rating.
The Load is reconnected automatically by every 3 seconds in 10 minutes.
If the overload remains, LED becomes solid and disconnects.※¹
