• There are no serviceable parts for this controller. Do NOTdisassemble or attempt to
repair the controller.

Charge Controller Safety
• NEVERconnect the solar panel array to the controller without a battery. Battery must be
connected first. This may cause a dangerous occurrence where the controller would
experience a high open circuit voltage at the terminals.

Open Circuit (V
oc
) to make sure the voltage does not exceed this value when connecting
panels together in series.

environment.
• Do NOT allow water to enter the controller.
Battery Safety

ventilation to release the gases.
