SAFETY
• Keep your Pulse Width Modulation (PWM) controller & battery away from any liquids
at all times.
• Keep the controller clean at all times (always check connectors to ensure they’re
free of grit before plugging them in).
• Do NOT use the solar controller to charge non-rechargeable batteries. Doing so may
result in harm to the user and/or damage the solar module, battery and controller.
Only use the provided solar blanket, regulator and adaptors/wiring provided in the
kit.
• All lead-acid batteries produce harmful, explosive gases. The battery should be
mounted in a well-ventilated area, as far as possible from any ignition sources. Do
NOT smoke or have a naked ame in the vicinity of the battery under charge.
• Never tamper with or pull any component of the regulator apart. Doing so will void
the warranty.
• The PWM controller is only suitable for regulating solar modules.
• The PWM controller is only suitable for lead-acid batteries: LEAD, AGM, GEL &
LITHIUM. The Solar Blanket & Controller should not be used with nickel metal
hydride batteries.
• Never connect more than 1 charging source to the PWM controller.
