DENRYO CO., LTD.

Thank you for purchasing

solar charge controller. This

1. Introduction

manual contains important safety, installation and operating instructionsfor

5-3：Explosion hazard

4. Precaution

Ver.1.04

solar charge controller in order to prevent the users

from any damage. Make sure to read all of the instructions and cautions

・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 you
need negative earth ground, connect only one terminal(battery or PV panel
or 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.

in the manual before beginning installation.

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

・When battery is connected, the output power is supplied to the load. If
charging starts, the output power is oﬀ after 5 minutes. You can checkthe load operation in this timing.
・If charging stops, the load will turn on about 10 minutes after.
